How do I choose the right person to make medical decisions for me? Choose someone who understands your values, can stay calm when information is incomplete, asks clinicians useful questions and will follow your wishes even when they would personally choose something different. Family closeness matters, but capability, willingness, availability and respect for your autonomy matter more.

The appointment is only the first step. The person also needs a clear explanation of what matters to you, the current legal document for your jurisdiction, a concise health summary, the names of key clinicians and instructions for finding the latest records. This guide gives you a practical selection process, a scorecard, conversation prompts, conflict scenarios and a preparation checklist.

How do I choose the right person to make medical decisions for me?

Start by defining the job. A medical decision-maker may need to listen to a clinical explanation, ask what the realistic options are, consider what you have said about comfort and acceptable recovery, consult the relevant documents and communicate a decision under time pressure. The role is not a reward for being the closest relative. It is a demanding responsibility that should be accepted knowingly.

Choose the person who can represent your values rather than their own. They do not need to predict every treatment choice. They need enough knowledge of your priorities to make a defensible decision when the exact situation was never discussed. For example, knowing that you value being able to recognise family and communicate may be more useful than a broad statement that you do not want “heroic measures”.

Good preparation also improves routine communication before a crisis. The article Doctor-Patient Calls Work Better With Shared Information shows why a caller who has medicines, recent changes, questions and authority details ready can use limited clinical time more effectively.

Advance Care Planning Australia explains what advance care planning involves. Healthdirect also covers advance care planning and substitute decision-making. Use official local guidance because the name, legal effect and witnessing process vary by jurisdiction.

Understand when the role begins and what it does not permit

A medical decision-maker does not normally take over simply because they have been appointed. While you can understand, weigh and communicate the relevant decision, your own informed choice remains central. The representative role usually becomes active when you cannot make or communicate the decision, subject to the law and clinical context where you live.

The role is also narrower than general control over your life. A healthcare appointment may not authorise financial transactions, access to every digital account or decisions about property. Separate appointments and permissions may be needed. Do not give a person passwords or unrestricted access merely because they have a health role.

The United States National Institute on Aging explains healthcare proxies and advance directives. MedlinePlus provides a separate overview of advance directives and healthcare agents. In England and Wales, GOV.UK distinguishes a lasting power of attorney from ordinary informal help. The NHS explains planning ahead for end-of-life care.

Use Evaheld’s planning ahead pathway to separate the appointment, health wishes, family communication and practical document access. This makes it less likely that relatives mistake one role for another.

Use a practical candidate scorecard

Selection factor	Strong evidence	Warning sign	Question to ask
Understands your values	Can explain what dignity, comfort and acceptable recovery mean to you	Repeatedly replaces your preferences with their own	“What do you think matters most to me if recovery is uncertain?”
Emotional steadiness	Can hear distressing information without ending the conversation	Avoids medical discussions or becomes unable to act	“How would you handle a decision that upset the family?”
Communication	Asks direct questions and summarises choices accurately	Interrupts, dominates or accepts unclear answers	“What would you ask if two options had different risks?”
Availability	Can be contacted, attend calls and arrange cover	Is frequently unreachable and refuses a backup plan	“Could you respond at short notice, and who would step in?”
Respect for autonomy	Accepts that your choice may differ from theirs	States that they would do what they believe is best regardless	“Could you follow my recorded wishes if you disagreed?”
Ability to manage conflict	Listens to relatives without surrendering the appointed role	Uses the position to settle old disputes	“How would you update siblings who strongly disagree?”
Practical organisation	Keeps records current and knows where originals are held	Loses documents or relies on memory	“Where would you find the latest directive and medicine list?”
Willingness	Has considered the burden and freely accepts it	Agrees from guilt or family pressure	“Do you genuinely want this role, and what support would you need?”

Score candidates honestly rather than using the table to justify a decision already made. A person who understands you deeply but cannot be contacted may be better as a trusted adviser than the sole formal appointee. A person who is organised and available but dismisses your values is not suitable.

Do not choose by family rank alone

A spouse, partner or adult child may be an excellent choice, but the relationship does not remove the need for assessment. Some spouses find it difficult to authorise comfort-focused care because they cannot separate hope from the person’s stated preferences. Some adult children live overseas, avoid conflict or have different religious views. Another relative or close friend may be better equipped to act.

Explain the appointment before a crisis. A clear statement can be brief: “I chose Sam because Sam can attend appointments, understands my priorities and stays calm with medical information. I still want everyone kept informed, but Sam will hold the formal role.” This separates authority from family importance.

If the family is already divided, do not assume the appointment will resolve the dispute. Consider whether the appointee needs written communication instructions, a neutral support person or professional advice about the legal form. Relationships Australia provides family relationship support, while the Better Health Channel outlines principles for clear communication in relationships.

Evaheld’s caring for parents and family guidance can help relatives record who holds authority, who should receive updates and which information should remain private.

Test willingness before completing the appointment

Ask directly rather than announcing the decision. Describe the possible tasks, including hospital calls, difficult conversations, reviewing documents, consulting clinicians and explaining choices to relatives. Give the person permission to decline. A reluctant appointee can create delay at the moment the role matters most.

Use a teach-back conversation. Explain one important value and ask the candidate to describe how it might guide a decision. For example: “If treatment could extend my life but was very unlikely to restore the ability to communicate, what would you want the clinicians to clarify?” The purpose is not to test medical knowledge. It is to see whether the person listens and asks the right next question.

Discuss uncertainty. Many real decisions are not a simple choice between complete recovery and death. A treatment may offer a modest chance of improvement, impose discomfort, require a trial period or lead to a different level of independence. The decision-maker must be able to ask about likely outcomes, timeframes, burdens and what happens if the treatment does not work.

The Conversation Project publishes a conversation starter guide that can help people begin values-based discussions. Use the questions as prompts, then record your own words rather than copying generic phrases into a directive.

Name a backup and build a continuity plan

People move, become ill, change relationships or decide they can no longer act. Where local law allows, appoint a backup and tell both people how the order works. A backup should receive enough information to step in without reconstructing the entire plan from relatives.

Location matters, but it is not the only factor. A person in another city may act effectively if they are reachable, comfortable with video calls and have authorised access to documents. A nearby relative who is frequently unavailable may be less practical. Consider time zones, mobile coverage, work restrictions, caring responsibilities and the ability to travel.

Review the appointment after separation, bereavement, serious diagnosis, cognitive change, relocation or a major conflict. Replace outdated copies and tell the clinical team where the current version is stored. Evaheld’s end-of-life planning guidance supports periodic review rather than treating the appointment as a one-time form.

The official Advance Care Planning Australia page provides state and territory planning links. NSW Health publishes advance care planning information for New South Wales. Queensland Health provides Queensland advance care planning guidance, and HealthyWA explains advance care planning in Western Australia.

$\"Medical$

Prepare the person with more than a legal form

The appointment document identifies authority. It may not explain what a good day means to you, which outcomes you would find unacceptable, how you balance comfort and longevity, or who you want included in discussions. Create a short values summary in plain language.

Include current medicines, allergies, diagnoses, treating clinicians, pharmacy, preferred hospital, communication needs and the location of relevant directives. Do not create a long medical autobiography. The representative needs a current, usable summary and a path to the source records.

Record family communication preferences. Decide who should receive updates, who should not receive sensitive information and whether one person will coordinate messages. This can prevent the decision-maker from spending critical time repeating the same explanation to several relatives.

Keep the current appointment separate from superseded versions. An online estate planning vault can organise legal records, while a health and care vault can hold the values, health summary and access instructions that support the role. The categories remain connected without giving every recipient access to every document.

The Victorian Office of the Public Advocate explains medical treatment decision-making in Victoria. Because the terminology and formal requirements differ, use the authority for your own jurisdiction before signing or replacing a document.

Prepare for the hardest conflict scenarios

The appointee personally disagrees

Ask before appointment whether the person could follow a choice they would not make for themselves. If the answer is uncertain, choose someone else or obtain professional guidance. A representative who intends to substitute personal beliefs for your stated values is not a safe choice.

Relatives pressure the appointee

Give the appointee a written explanation of the role and your communication preferences. Encourage them to listen, but make it clear that family consensus is not always required. A neutral clinician, social worker, pastoral-care worker or mediator may help when conflict becomes unmanageable.

The clinical explanation is unclear

The appointee should ask for plain language, likely outcomes and the reason a recommendation is being made. Useful questions include: What problem is the treatment trying to solve? What is the best likely outcome? What is the worst likely outcome? How soon will we know whether it is working? Can it be tried for a limited period?

The documents cannot be found

Do not rely on one paper copy in a locked home. Record where the signed original is held, who has a copy and how the current version can be accessed. Do not send unrestricted personal information to everyone “just in case”. Use selective access and review it when relationships change.

Protect privacy without blocking necessary access

A decision-maker needs enough information to act, not automatic access to every family, financial or digital record. Separate health information, legal documents, passwords, personal messages and estate notes. Apply the least access required for each role.

The Office of the Australian Information Commissioner explains privacy rights relating to health information. Ask clinicians how an appointed person’s authority will be verified and what information can be shared before incapacity.

Do not place passwords in the directive or email them to relatives. Store access instructions separately and use account recovery or authorised sharing where available. Review the recipients whenever the formal appointment changes.

Evaheld’s digital legacy platform can keep the appointment, values, health summary, practical access notes and private messages in separate Rooms. The account holder can share selected material with the decision-maker without exposing unrelated records.

Common mistakes when choosing a medical decision-maker

Choosing the eldest relative automatically: Family order does not establish capability or willingness.
Asking after the form is signed: The person should understand and accept the role first.
Recording only treatment labels: Explain the values and outcomes that matter to you.
Appointing two people without a conflict process: Confirm whether they act jointly, separately or in sequence.
Ignoring availability: Test how the person will respond outside ordinary hours and while travelling.
Failing to name a backup: A single appointee can become unavailable.
Keeping the document secret: Relevant clinicians and trusted people should know it exists and where the current copy is held.
Giving excessive access: Share only the information required for the role.
Leaving old copies in circulation: Mark superseded documents clearly and replace them.
Never reviewing the choice: Health, relationships, location and willingness can change.

How Evaheld helps prepare a medical decision-maker

Evaheld can connect the formal appointment with the practical information the person will need. The account holder can store the signed document, create a plain-language values summary, record clinician and pharmacy contacts, note where originals are held and organise relevant health information.

Private and shared Rooms let the account holder separate a decision-maker’s material from personal messages, financial records and family stories. A person can share the health summary and directive without sharing every item in the account. Access can be reviewed when appointments or relationships change.

Evaheld can also preserve the explanation behind the form. A short voice note may describe what comfort, independence, communication or time with family means to the person. The recording does not replace a legally valid directive, but it can help the representative understand the values that should guide an unforeseen decision.

Families can compare digital legacy vault plans where they need different storage or sharing arrangements. Start with the minimum information that would help in a crisis, then add detail after the essentials are accurate.

Final medical decision-maker checklist

Describe the role and the decisions it may involve.
List two or three possible candidates instead of defaulting to family rank.
Assess values, steadiness, communication, availability, conflict skills and willingness.
Ask the preferred person directly and allow them to decline.
Use teach-back to check whether they understand your priorities.
Complete the correct local appointment and witnessing process.
Name a backup where permitted.
Give the appointee the current document, values summary, health overview and clinician contacts.
Record who should receive family updates and what remains private.
Store the current version where it can be found and replace old copies.
Review the appointment after major health, family or location changes.
Tell relevant clinicians and trusted people how the current record can be accessed.

Create the supporting record in Evaheld by linking the appointment, health summary and access instructions inside a medical decision-maker workflow that you can update as circumstances change.

FAQs about choosing a medical decision-maker

How do I choose the right person to make medical decisions for me? What to know

Choose someone who understands your values, stays calm, asks useful questions and can follow your wishes when other people disagree. Test the choice by discussing one realistic scenario and asking the person to explain what they would clarify before deciding. Doctor-Patient Calls Work Better With Shared Information shows why prepared context matters, and Advance Care Planning Australia explains the wider planning process.

Should I automatically appoint my spouse or oldest child?

No. A spouse or adult child may be suitable, but family position does not prove willingness, availability or the ability to follow your choices. Explain the selection criteria to the family before a crisis. Evaheld’s planning ahead pathway can separate authority from the communication plan, while Better Health Channel outlines clear relationship communication.

What qualities matter most in a medical decision-maker?

Prioritise respect for your autonomy, emotional steadiness, reliability, listening, clear communication and the ability to manage disagreement. Medical expertise is not required, but the person must be willing to ask questions. A health and care vault can hold the values and records they need, and MedlinePlus explains the purpose of healthcare agents and directives.

Should I name a backup medical decision-maker?

Name a backup where the local process permits it. The first person may be travelling, unwell, unreachable or unwilling when the role begins. Evaheld’s end-of-life planning guidance supports a continuity plan, and the official Australian portal provides state and territory appointment resources.

What should I give my appointed decision-maker?

Provide the current appointment, directive, medicine list, allergies, key diagnoses, clinician contacts, document locations and a plain-language values summary. Do not overwhelm the person with obsolete records. A digital legacy platform can keep the pieces connected, while the OAIC explains privacy rights for health information.

What if relatives disagree with the person I appoint?

Explain why the person was selected and distinguish formal authority from the right to be consulted or updated. Record who should receive information and who should not. Evaheld’s caring for parents and family guidance can clarify roles, and Relationships Australia provides support for difficult family conflict.

Can my medical decision-maker live in another city or country?

Possibly, but assess time zones, availability, travel, local legal requirements and access to records. Name a nearby backup if remote communication could delay urgent decisions. Review the sharing options in digital legacy vault plans, and the National Institute on Aging explains how healthcare proxies fit into advance planning.

Can I change my medical decision-maker later?

Usually, but follow the revocation and replacement process for your jurisdiction. Collect old copies, notify relevant clinicians and update every person who held access. An online estate planning vault can distinguish current and superseded records, while the Victorian Office of the Public Advocate explains medical treatment decision-making requirements.

Does the person control my care while I can make decisions?

Generally no. Your own informed choice remains central while you can make and communicate the relevant decision. The appointment usually operates only when capacity for that decision is absent, subject to local law. Keep the appointment and supporting preferences in a health and care vault, and the NHS explains planning ahead while you can express your wishes.

How can Evaheld help prepare a medical decision-maker?

Evaheld can connect the appointment, values, health summary, clinician contacts, document locations and selective sharing instructions. The person can receive the Rooms relevant to the role without gaining access to unrelated private material. Evaheld’s digital legacy platform keeps the record updateable, and The Conversation Project provides values-based conversation prompts for the discussion.

Where local law allows, appoint a backup and tell both people how the order works. A backup should receive enough information to step in without reconstructing the entire plan from relatives. Location matters, but it is not the only factor. A person in another city may act effectively if they are reachable, comfortable with video calls and have authorised access to documents. A nearby relative who is frequently unavailable may be less practical. Consider time zones, mobile coverage, work restrictions, caring responsibilities and the ability to travel. Review the appointment after separation, bereavement, serious diagnosis, cognitive change, relocation or a major conflict. Replace outdated copies and tell the clinical team where the current version is stored. Evaheld’s end-of-life planning guidance supports periodic review rather than treating the appointment as a one-time form. The official Advance Care Planning Australia page provides state and territory planning links . NSW Health publishes advance care planning information for New South Wales. Queensland Health provides Queensland advance care planning guidance , and HealthyWA explains advance care planning in Western Australia . Prepare the person with more than a legal form The appointment document identifies authority. It may not explain what a good day means to you, which outcomes you would find unacceptable, how you balance comfort and longevity, or who you want included in discussions. Create a short values summary in plain language. Include current medicines, allergies, diagnoses, treating clinicians, pharmacy, preferred hospital, communication needs and the location of relevant directives. Do not create a long medical autobiography. The representative needs a current, usable summary and a path to the source records. Record family communication preferences. Decide who should receive updates, who should not receive sensitive information and whether one person will coordinate messages. This can prevent the decision-maker from spending critical time repeating the same explanation to several relatives. Keep the current appointment separate from superseded versions. An online estate planning vault can organise legal records, while a health and care vault can hold the values, health summary and access instructions that support the role. The categories remain connected without giving every recipient access to every document. The Victorian Office of the Public Advocate explains medical treatment decision-making in Victoria. Because the terminology and formal requirements differ, use the authority for your own jurisdiction before signing or replacing a document. Prepare for the hardest conflict scenarios The appointee personally disagrees Ask before appointment whether the person could follow a choice they would not make for themselves. If the answer is uncertain, choose someone else or obtain professional guidance. A representative who intends to substitute personal beliefs for your stated values is not a safe choice. Relatives pressure the appointee Give the appointee a written explanation of the role and your communication preferences. Encourage them to listen, but make it clear that family consensus is not always required. A neutral clinician, social worker, pastoral-care worker or mediator may help when conflict becomes unmanageable. The clinical explanation is unclear The appointee should ask for plain language, likely outcomes and the reason a recommendation is being made. Useful questions include: What problem is the treatment trying to solve? What is the best likely outcome? What is the worst likely outcome? How soon will we know whether it is working? Can it be tried for a limited period? The documents cannot be found Do not rely on one paper copy in a locked home. Record where the signed original is held, who has a copy and how the current version can be accessed. Do not send unrestricted personal information to everyone “just in case”. Use selective access and review it when relationships change. Protect privacy without blocking necessary access A decision-maker needs enough information to act, not automatic access to every family, financial or digital record. Separate health information, legal documents, passwords, personal messages and estate notes. Apply the least access required for each role. The Office of the Australian Information Commissioner explains privacy rights relating to health information . Ask clinicians how an appointed person’s authority will be verified and what information can be shared before incapacity. Do not place passwords in the directive or email them to relatives. Store access instructions separately and use account recovery or authorised sharing where available. Review the recipients whenever the formal appointment changes. Evaheld’s digital legacy platform can keep the appointment, values, health summary, practical access notes and private messages in separate Rooms. The account holder can share selected material with the decision-maker without exposing unrelated records. Common mistakes when choosing a medical decision-maker Choosing the eldest relative automatically: Family order does not establish capability or willingness. Asking after the form is signed: The person should understand and accept the role first. Recording only treatment labels: Explain the values and outcomes that matter to you. Appointing two people without a conflict process: Confirm whether they act jointly, separately or in sequence. Ignoring availability: Test how the person will respond outside ordinary hours and while travelling. Failing to name a backup: A single appointee can become unavailable. Keeping the document secret: Relevant clinicians and trusted people should know it exists and where the current copy is held. Giving excessive access: Share only the information required for the role. Leaving old copies in circulation: Mark superseded documents clearly and replace them. Never reviewing the choice: Health, relationships, location and willingness can change. How Evaheld helps prepare a medical decision-maker Evaheld can connect the formal appointment with the practical information the person will need. The account holder can store the signed document, create a plain-language values summary, record clinician and pharmacy contacts, note where originals are held and organise relevant health information. Private and shared Rooms let the account holder separate a decision-maker’s material from personal messages, financial records and family stories. A person can share the health summary and directive without sharing every item in the account. Access can be reviewed when appointments or relationships change. Evaheld can also preserve the explanation behind the form. A short voice note may describe what comfort, independence, communication or time with family means to the person. The recording does not replace a legally valid directive, but it can help the representative understand the values that should guide an unforeseen decision. Families can compare digital legacy vault plans where they need different storage or sharing arrangements. Start with the minimum information that would help in a crisis, then add detail after the essentials are accurate. Final medical decision-maker checklist Describe the role and the decisions it may involve. List two or three possible candidates instead of defaulting to family rank. Assess values, steadiness, communication, availability, conflict skills and willingness. Ask the preferred person directly and allow them to decline. Use teach-back to check whether they understand your priorities. Complete the correct local appointment and witnessing process. Name a backup where permitted. Give the appointee the current document, values summary, health overview and clinician contacts. Record who should receive family updates and what remains private. Store the current version where it can be found and replace old copies. Review the appointment after major health, family or location changes. Tell relevant clinicians and trusted people how the current record can be accessed. Create the supporting record in Evaheld by linking the appointment, health summary and access instructions inside a medical decision-maker workflow that you can update as circumstances change.

A further practical next step is navigating the doctor registration process in australia , which helps connect this article’s ideas with a broader family plan. FAQs about choosing a medical decision-maker How do I choose the right person to make medical decisions for me? What to know Choose someone who understands your values, stays calm, asks useful questions and can follow your wishes when other people disagree. Test the choice by discussing one realistic scenario and asking the person to explain what they would clarify before deciding. Doctor-Patient Calls Work Better With Shared Information shows why prepared context matters, and Advance Care Planning Australia explains the wider planning process . Should I automatically appoint my spouse or oldest child? No. A spouse or adult child may be suitable, but family position does not prove willingness, availability or the ability to follow your choices. Explain the selection criteria to the family before a crisis. Evaheld’s planning ahead pathway can separate authority from the communication plan, while Better Health Channel outlines clear relationship communication . What qualities matter most in a medical decision-maker? Prioritise respect for your autonomy, emotional steadiness, reliability, listening, clear communication and the ability to manage disagreement. Medical expertise is not required, but the person must be willing to ask questions. A health and care vault can hold the values and records they need, and MedlinePlus explains the purpose of healthcare agents and directives . Should I name a backup medical decision-maker? Name a backup where the local process permits it. The first person may be travelling, unwell, unreachable or unwilling when the role begins. Evaheld’s end-of-life planning guidance supports a continuity plan, and the official Australian portal provides state and territory appointment resources . What should I give my appointed decision-maker? Provide the current appointment, directive, medicine list, allergies, key diagnoses, clinician contacts, document locations and a plain-language values summary. Do not overwhelm the person with obsolete records. A digital legacy platform can keep the pieces connected, while the OAIC explains privacy rights for health information . What if relatives disagree with the person I appoint? Explain why the person was selected and distinguish formal authority from the right to be consulted or updated. Record who should receive information and who should not. Evaheld’s caring for parents and family guidance can clarify roles, and Relationships Australia provides support for difficult family conflict . Can my medical decision-maker live in another city or country? Possibly, but assess time zones, availability, travel, local legal requirements and access to records. Name a nearby backup if remote communication could delay urgent decisions. Review the sharing options in digital legacy vault plans , and the National Institute on Aging explains how healthcare proxies fit into advance planning. Can I change my medical decision-maker later? Usually, but follow the revocation and replacement process for your jurisdiction. Collect old copies, notify relevant clinicians and update every person who held access. An online estate planning vault can distinguish current and superseded records, while the Victorian Office of the Public Advocate explains medical treatment decision-making requirements. Does the person control my care while I can make decisions? Generally no. Your own informed choice remains central while you can make and communicate the relevant decision. The appointment usually operates only when capacity for that decision is absent, subject to local law. Keep the appointment and supporting preferences in a health and care vault , and the NHS explains planning ahead while you can express your wishes. How can Evaheld help prepare a medical decision-maker? Evaheld can connect the appointment, values, health summary, clinician contacts, document locations and selective sharing instructions. The person can receive the Rooms relevant to the role without gaining access to unrelated private material. Evaheld’s digital legacy platform keeps the record updateable, and The Conversation Project provides values-based conversation prompts for the discussion.","scheduled":null,"categories":[{"label":"Health, Advance Care Planning & Care Wishes","value":"626ba897-70e7-45c5-b800-f81979fc1464"}],"multiauthors":[{"label":"Charli Evaheld, Legacy Expert","value":"153de11c-9ce8-4d79-9d19-c10da778e84c"}],"tags":[{"label":"Advance Care Planning Guides and Resources","value":"f34eb449-00fb-49dd-9566-3e7d3082f116"}],"toc_status":true,"restricted":false,"restricted_percentage":30,"authors":{"id":"5df9480f-2659-40dd-a62f-beaa65e0fc66","cta":null,"theme":{"layout":"stack","custom_theme":":root {\n --c-primary-50: 241, 232, 248;\n --c-primary-100: 224, 204, 239;\n --c-primary-200: 196, 158, 225;\n --c-primary-300: 165, 107, 209;\n --c-primary-400: 136, 60, 195;\n --c-primary-500: 102, 45, 145;\n --c-primary-600: 82, 36, 117;\n --c-primary-700: 60, 27, 86;\n --c-primary-800: 41, 18, 58;\n --c-primary-900: 19, 8, 27;\n }","theme_colour":"#662D91","translation_strings":{"home":{"articles":"","catfilter":""},"post":{"share":"","months":{"apr":"","aug":"","dec":"","feb":"","jan":"","jul":"","jun":"","mar":"","may":"","nov":"","oct":"","sep":""},"min_read":"time to read","share_post":"Share this article","related_posts":"Related Articles"},"common":{"error_msg":"","showmorebtn":"","search_placeholder":""},"category":{"posts":"Articles"},"newsletter":{"subscribe":"Sign Up For Free","nlplaceholder":"","continue_reading":"","subscribe_popup_btn":"Sign Up For Free","subscribe_found_message":"You are already signed up to Evaheld","subscribe_exit_intent_btn":"Sign Up For Free","subscribe_success_message":"You have successfully signed up for Evaheld","subscribe_acceptance_message":""},"all_content":{"explore_all_tags":"","find_all_authors":"","explore_all_categories":""},"breadcrumbs":{"tag_breadcrumbs":"","posts_breadcrumbs":"","author_breadcrumbs":"","category_breadcrumbs":""},"gated_content":{"gated_content_acceptance_msg":"","gated_content_name_placeholder":"","gated_content_email_placeholder":""}}},"users":{"slug":"charli","full_name":"Charli Evaheld, Legacy Expert","avatar_url":"https://auth.typeflo.io/storage/v1/object/public/authors/public/5df9480f-2659-40dd-a62f-beaa65e0fc66/images/avatar.webp?1786768858049"},"embedded":null,"username":"trial","metatitle":"Digital Legacy Vault - Estate Planning, Care Wishes & Stories","cus_domain":"yes","newsletterC":{"popup":null,"title":"Start your Legacy Vault - Free Forever","subtitle":"Your story, estate planning and care wishes, in one secure digital time capsule","acceptance":"","exit_intent":{"title":"Wait!

Prepare for future healthcare decisions by documenting your treatment preferences, personal values, substitute decision-makers and care wishes.

Explore guidance on advance care directives, enduring guardians, emergency health information and conversations with family and clinicians. These resources can help you clarify what matters most before illness, injury or cognitive decline limits your ability to communicate.

Explore the complete health and care planning platform to see how directives, care wishes, medical information, supporting documents and trusted contacts can be organised together.

Advance care planning is not only for older people or those with a diagnosis. It gives any adult greater control and helps prevent loved ones from being left to guess during a medical crisis.

Create your free advance care planning vault and record your first care preference, decision-maker or emergency health detail.
