Estate planning can feel like something you will get around to one day. Then life gets busy, the paperwork ends up in different places, and years pass. Some of the costliest mistakes are surprisingly ordinary: an old super nomination, a will nobody can find, or an executor who has never been told they have the job.
You may have written everything down with the best intentions. But will those instructions work when your family needs them? A few careful checks now can spare people a great deal of guesswork later.
Here are 13 mistakes worth looking for, with clear ways to avoid them. At the end, there is a checklist you can actually use — whether you are starting from scratch or dusting off a plan you made years ago.
Why estate planning mistakes happen even when you have a will
A will directs what happens to assets that form part of your estate. It does not automatically deal with all superannuation benefits, jointly owned property, trust assets, company property, decisions made during incapacity or access to online accounts. Understanding how wills and powers of attorney work is a useful first step.
Think of it this way: first, the right documents need to exist. Second, they need to govern the assets and decisions you think they do. Third, the right people need to find them. You can bring the practical details together by organising estate documents and important information in one place.
First, know what kind of mistake you are fixing, below are the top 13
Some mistakes are about the will itself: its validity, wording or missing provisions. Others affect who actually receives an asset, because superannuation, joint ownership or a trust may follow separate rules. The third group is practical: your wishes are documented, but nobody can find the right record or knows what to do. You may have more than one type of problem, and each needs a different solution.
If you have only ten minutes, start by checking the signed will, the latest superannuation nomination and whether your executor knows where the originals are. Those three checks won't complete your plan, but they can expose a surprising amount.
1. Not having a valid will
“I don’t really own much” is one of the easiest reasons to put a will off. So is “my family knows what I want”. But even modest estates involve decisions, and families do not always agree on what they remember you saying.
What can happen without one
Without a valid will, intestacy rules may decide who receives your estate, and someone may need to apply for authority to administer it. The outcome may not match your relationships or priorities.
Make the will you actually need
Create your legally valid will with Evaheld's guided online will maker. Identify your beneficiaries, appoint your executor, include appropriate replacement arrangements and record how you want your estate distributed. Follow the signing and witnessing steps for your jurisdiction and keep the executed version easy to identify.
A useful first step
Do you have a signed, current will? Does your executor know where the original is? If not, begin by put the essential legal documents in place.
2. Signing your will incorrectly or losing the original
The will is finished, everyone feels relieved—and then the signed copy disappears into a filing cabinet. Or the witnesses were not present as required. Either problem can make an already difficult time harder.
Why the original matters
The intended document may be challenged, additional evidence may be required, and your executor may struggle to establish which will governs the estate.
Avoid confusion about the final version
Complete the required execution process. Record the signing date, witness information and exact location of the original. Label digital copies clearly and identify superseded versions rather than leaving multiple files named “final will”.
Try this simple test
Ask your nominated executor to explain where the signed original is stored. If they cannot answer, record its location and the relevant contact. Next, prepare clear instructions for your executor and family so they know what to look for when the time comes.
Four will-drafting details worth checking
Correct signing is essential, but it doesn't rescue unclear instructions. Ask whether your will covers what happens to the remainder of your estate after specific gifts have been made. Lawyers call this the residuary clause. Also check whether a gift names a person or property clearly, whether substitute beneficiaries are provided for, and whether an asset specifically gifted in the will might be sold before death.
The Legal Practitioners’ Liability Committee identifies missing residuary clauses, ambiguous descriptions of beneficiaries and drafting errors among recurring problems in wills. These are not theoretical concerns: disputes over a word such as “children” can involve costly interpretation, particularly in blended families.
A realistic example: the house that isn't there anymore
Imagine leaving a particular house to your niece, then selling it and moving into an apartment without reviewing the will. A specific gift may no longer take effect as intended when the property is no longer in the estate. This is known as ademption. The outcome depends on the wording and law, so the sensible action is to review the will whenever you sell or replace a specifically gifted asset.
For NSW readers, Legal Aid NSW explains will-making requirements and testamentary capacity, while the Supreme Court outlines the importance of the original will in probate.
3. Assuming your will controls superannuation, insurance and every asset
In Australia, superannuation death benefits are governed by fund rules, superannuation law and applicable nominations. Joint tenancy, trust structures and insurance arrangements can also mean an asset or payment does not pass under your will.
Where the surprise comes from
An intended beneficiary might not receive an asset merely because they are named in your will. A nomination may have expired, or the legal owner may be an entity rather than you personally.
Check the arrangements outside your will
For each major asset, record its legal owner, governing document or nomination, intended recipient and the professional or provider who can verify the outcome. Check whether superannuation nominations are binding, non-binding, lapsing or non-lapsing.
Check your super first
Find your latest superannuation nomination and ask your fund to confirm its status. Then document your property and assets, including who legally owns them and where the supporting records are held.
In Australia, wills and superannuation arrangements need to be considered together, rather than assuming one automatically controls the other.
A realistic example: the nomination nobody checked
Suppose your will leaves everything to your two children but an old superannuation nomination still identifies a former partner. Your family cannot assume the will overrides the fund’s governing rules. The useful check is not just reading the will: it is confirming the current nomination directly with the fund, its status and whether the nominated person is eligible.
4. Leaving beneficiaries and family arrangements out of date
Marriage, separation, divorce, death, children, new dependants and major lifetime gifts can all change who you intend to benefit. An old document may remain on file long after your circumstances have changed.
Why yesterday’s decisions may no longer fit
A beneficiary may have died, a substitute may be missing, or the plan may no longer account for someone who relies on you. Unequal gifts can also create surprise and resentment if the circumstances behind them were never properly considered.
Review people, not just paperwork
Check full legal names, substitutes, minors, charities, people with disabilities, people intentionally excluded and nominations held by providers. Where gifts differ between children, assess dependency, caregiving, family-business interests and prior support rather than relying on assumptions.
An important question
Write down who would receive each major asset under the current arrangements. If you're wrestling with whether an unequal inheritance is fair, consider how different gifts to your children might be understood and how to explain your thinking respectfully.
5. Choosing an executor or decision-maker without preparing them
The eldest child or nearest relative is not automatically the most suitable executor. An executor must manage legal and administrative obligations, deal with providers and beneficiaries, and maintain reliable records.
The problem with choosing by family rank
A person who is unwilling, unavailable, conflicted or unaware of the appointment may struggle when the work begins. Naming multiple people without considering disagreements can cause additional difficulty.
Give your executor a fair start
Choose someone for willingness, judgement, availability and communication skills. Ask before appointing them, consider a backup, explain the role and tell them where the will and essential contacts can be found.
Would they know where to begin?
Can your executor name your solicitor, locate your signed will and find a first list of assets and liabilities? If not, prepare an executor checklist with the first practical tasks.
6. Forgetting incapacity and healthcare planning
Estate planning should address more than what happens after death. Illness, injury or cognitive change can affect your ability to make or communicate decisions while you are alive. A will does not itself appoint a financial or healthcare decision-maker during incapacity.
The gap families discover in a crisis
Your family might know what you want, yet be unsure who is authorised to speak for you. Your care team may also be missing everyday details — from allergies and medicines to the people who should be called first.
Put your care wishes within reach
Consider the relevant power of attorney, guardianship or healthcare appointment, and advance care documentation for your jurisdiction. Record your values, preferences, care team and emergency contacts. Speak with the people likely to support you.
One question worth answering
Could a trusted person identify your care wishes and the relevant decision-maker? Keep advance care wishes, health information and emergency details organised, with appropriate access for the people who may need them.
7. Overlooking jointly owned property, trusts and business interests
You may control an asset without owning it personally. A company director does not personally own the company's assets simply by managing them; trust assets and jointly held property have their own governing arrangements.
Why ownership changes the outcome
Your will cannot automatically distribute property that is not part of your estate. Business control, trust succession and joint ownership may require separate legal and administrative steps.
Make an asset-and-control map
Collect titles, trust deeds, shareholder agreements, partnership documents and any relevant succession provisions. Record both ownership and control. Complex arrangements should be checked with appropriate legal, tax and financial advisers.
Start with your property records
Identify every asset you use but may not own outright. A home inventory for insurance and estate planning can also capture household contents, heirlooms, receipts and valuable collections that formal statements may miss.
What professional claims reveal about property ownership
The Legal Practitioners’ Liability Committee's will-preparation checklist specifically calls for ownership checks and careful consideration of joint tenancies. In its published claims examples, property understood to be available for a gift under a will was actually held as joint tenants or belonged to a company. For your own plan, don't rely on memory: check the title and entity records before assuming who can inherit an asset.
8. Ignoring blended families, vulnerable beneficiaries and potential disputes
Blended families, stepchildren, former partners, disabled dependants, family businesses and unequal lifetime support can make estate planning significantly more complex. Equal shares may not meet everyone's needs; unequal shares may not be understood without context.
Where misunderstandings begin
Family provision laws may permit eligible people to seek provision in certain circumstances. Unclear guardianship, beneficiary arrangements or assumptions about who depends on you can produce expensive conflicts.
Plan for the family you actually have
Map important relationships and dependencies. Consider arrangements for minor children, people with disability and anyone financially dependent on you. Record relevant facts, discuss suitable structures with an adviser and communicate decisions with care.
What to consider now
Does the plan consider everyone whose needs or claims may matter? Thinking through consider how complex family relationships affect your wishes can help clarify your reasoning. A separate letter of wishes can communicate that context without trying to rewrite the will.
A realistic example: two meanings of “my children”
Imagine a family in which one partner has children from a previous relationship and the couple also has a child together. A will that refers generally to “my children” may raise questions about who was intended to benefit. The Legal Practitioners’ Liability Committee describes ambiguity over beneficiaries as a recurring source of disputes. Clear naming and a review of the entire family structure are more useful than hoping everyone interprets a phrase in the same way.
9. Ignoring digital assets, passwords and online accounts
Financial accounts, email, cloud photographs, cryptocurrency, domains, online businesses, subscriptions and social media may all matter after death. Simply writing passwords in a will or shared family folder is not an adequate access plan.
The risks of leaving accounts unaccounted for
Important accounts may be forgotten or inaccessible. Sensitive credentials can be exposed, while access to a password does not itself establish authority to operate an account. Devices and multi-factor authentication can also create unexpected barriers.
Leave a safe route, not a list of passwords
Maintain an account inventory that identifies what exists, why it matters, the authorised route to access, relevant recovery settings and whether content should be retained, transferred, memorialised or closed. Use a secure password manager and multi-factor authentication.
Test your digital handover
Can a trusted person identify your important online accounts and the approved way to manage them? Start by understanding what happens to digital assets after death. Then make an inventory of your online accounts and record the recovery and after-death arrangements for each one.
10. Leaving your executor and family without practical instructions
Picture your executor at the kitchen table, facing a pile of statements and a locked phone. Who holds the mortgage? Which insurer covers the house? Where are the accountant’s details? A will rarely answers those questions.
Why a will is not a set of instructions
Family members can spend valuable time searching folders and devices, phoning providers and trying to distinguish current information from old records. Meanwhile the person handling funeral arrangements may need different information from the estate administrator.
Write down the details only you know
Create an executor handover covering the original will location, advisers, assets, liabilities, insurance, super, business contacts and first practical actions. Keep private healthcare information, sensitive credentials and personal messages separately permissioned.
An easy way to test it
Ask an appointee to find three important records without help. If it proves difficult, share selected information and request missing details through private or shared Rooms rather than granting access to everything.
A realistic example: the executor who cannot find the original
Your brother agrees to be executor. Years later, he has a scanned will but cannot identify where the signed original is kept. He may then face additional enquiries or evidence requirements instead of simply producing the executed document. The NSW Supreme Court explains the extra process when an original will cannot be located. A clear original-location note is a small task that can prevent a much bigger problem.
11. Using a letter of wishes as if it changes legal rights
Personal instructions can beautifully explain family history, heirlooms, guardianship preferences, funeral wishes and reasons for unequal gifts. But a personal letter should not be used as an inconsistent substitute for the operative legal documents.
When a kind explanation causes confusion
A letter that attempts to change beneficiaries, promise property or contradict a will can create confusion and arguments about what you intended.
Keep the legal and personal messages distinct
Keep formal legal arrangements separate from personal explanations. Write about values and intentions in clear, respectful language, and avoid allegations or private family disputes that would cause unnecessary harm if circulated.
Read your letter alongside your will
Does your personal letter explain your wishes without contradicting your will? You may find it easier to begin with write down your wishes without contradicting your will or to write a statement about the values you want to pass on. Keep personal messages and memories separate from formal instructions in your Story & Legacy Vault.
12. Creating an estate plan but not implementing it
Writing down a decision does not automatically update a superannuation fund, register a property transfer, amend a trust, change a policy beneficiary or complete an appointment. A plan can look finished while essential action remains undone.
What gets missed after the documents are signed
Outdated provider records and ownership arrangements may continue to govern despite what your newly drafted documents say.
Follow through with a simple action register
Keep an implementation register. For each task, identify the provider, responsible person, required documentation, date submitted, confirmation received and next review date. Treat an action as complete only when the relevant process has been confirmed.
Choose one unfinished task
Find one unfinished step and complete or schedule it. Keep each action, contact and supporting record together as you identify the estate planning records you still need.
13. Never reviewing and updating your estate plan
Plans become stale after marriage, separation, divorce, births, deaths, diagnoses, relocation, property changes, business transactions and new relationships. Even unchanged legal documents can be supported by outdated contact or access information.
How a good plan becomes yesterday’s plan
Appointees may no longer be suitable, nomination details may change, and your family may rely on obsolete instructions or lose access to the information needed.
Build review into the way you plan
Review legal arrangements after material life events and check contact details, document locations, permissions and asset inventories periodically. Mark old versions as superseded and remove access that is no longer appropriate.
Check the date
When did you last check your executor, nominations, contacts and document locations? Keeping estate, health and personal records connected makes it easier to notice what needs updating when life changes.
How to audit your estate plan in seven areas
For example, suppose your will says your daughter should inherit your savings, but an old super nomination still names someone else. Finding that mismatch while you are alive gives you a chance to check the fund’s rules and put the right paperwork in place. That is what this audit is for: spotting the gaps between your intentions and the arrangements that actually apply.
Do not stop at reading your will. Test the entire system. The document test checks whether the instruments are current and appropriately completed; the control test checks which arrangement governs each asset or decision; and the handover test checks whether the authorised person can find and act on the relevant information.
Audit area | Question to answer | Evidence to inspect |
|---|---|---|
Authority | Can the named person act, and is there a suitable backup? | Will, powers of attorney, guardianship and health appointments |
Ownership | Does the will actually control this asset? | Titles, statements, trust and company records |
Beneficiaries | Are the intended recipients and contingencies current? | Will, fund nominations, insurance policies, trust terms |
Incapacity | Who acts if you cannot decide or communicate? | Appointments, directives and care details |
Access | Can the correct person find the right version? | Original-location notes, permissions and recovery paths |
Execution | Were signing and provider actions completed? | Signed originals, registration or provider confirmations |
Maintenance | What needs updating after a life event? | Review dates, changes in family or assets, contact records |

FAQs about estate planning mistakes
What is the most common estate planning mistake?
Not having a current will is one of the most serious mistakes. Another is assuming a will handles every asset and decision. It helps to understand where an estate plan commonly breaks down, then organise your will, asset details and key contacts together so gaps are easier to spot.
What happens if I die without a will in Australia?
If you die without a valid will, intestacy laws determine how your estate is distributed. The rules differ across Australian states and territories and may not reflect your wishes. Work through the documents and decisions worth putting in place, and put the essential legal documents in place.
Can I create a legally valid will online?
Yes. Evaheld enables you to create a legally valid will online through its guided will maker. Complete the signing and witnessing steps applicable to your jurisdiction. For more complex estates, understand when tailored legal advice may add value alongside your planning, then keep your executed will and estate documents organised for the people who need them.
Does my will include my superannuation?
Not automatically. Superannuation death benefits are subject to fund rules, applicable law and any valid nomination. Understanding which records belong in a complete estate plan helps you identify what to check with your fund. You can then record your super, policies and asset details for your future reviews and executor.
What mistakes cause an executor the most trouble?
Missing originals, outdated asset details, unknown debts and scattered account information can create avoidable work. Prepare a practical handover your executor can follow, and keep essential documents and contacts easy to find rather than leaving them to search through emails and drawers.
How can I reduce inheritance disputes in a blended family?
Identify everyone who may be affected, consider dependants and potential claims, and obtain advice about your circumstances. If you are considering different inheritances for different children, work through the fairness questions. You can also preserve thoughtful personal explanations and messages for family members separately from your legally operative instructions.
What digital accounts should be included in estate planning?
Start with email, banking, cloud files, photographs, subscriptions, social accounts and any digital investments. Think about what happens to digital property after death, then organise the important accounts and their intended next steps. Include legitimate recovery routes rather than assuming someone can simply use your passwords.
Should I put passwords in my will?
No. A will is not the place for passwords that change or could be disclosed through estate administration. Identify the accounts and lawful recovery methods you need to record, then keep credentials in a secure password manager rather than in a shared document.
Do I need advance care planning as well as a will?
Yes. A will generally operates after death. Healthcare wishes and decision-making appointments matter while you are alive. Start by identifying the care and legal documents your family may need. Then keep your care preferences and trusted contacts connected so the right people can find them when needed.
How often should I update my estate plan?
Review the plan after changes such as marriage, separation, births, deaths, substantial financial changes or changed appointees. consider how family relationships affect your legacy arrangements, then keep account details and document locations up to date. Check fund nominations and other records for their own deadlines.
Can Evaheld help me avoid estate planning mistakes for free?
Yes. You can start with one important document, contact or instruction, then build the rest over time. If you're unsure what to tackle first, check the practical details families commonly overlook. Then start your free Legacy Vault with the first missing item from your checklist.
Continue exploring estate, care and legacy topics, answers to common planning questions, or put your legal, health and family records on one checklist.
