Dementia and Estate Planning: Ensuring Validity in QLD Wills

Disclaimer: The following article is for general educational purposes only and does not constitute legal or medical advice. Laws regarding wills and estate planning vary, and each person’s health scenario is different. If you live in Queensland or have cross-border considerations, consult both a qualified solicitor and, where necessary, a medical professional. This ensures your estate plan fully complies with local law and accounts for any diagnosis like dementia or related cognitive conditions.

Dementia-related conditions—including Alzheimer’s disease—often lead to declining cognitive capacity, posing challenges for individuals looking to create or update a will. Under Queensland law, a testator must have “testamentary capacity” when signing their will for it to remain valid. Below is a guide to help you understand how dementia can affect estate planning, the steps to ensure a will’s validity in Queensland, and ways to protect loved ones if cognitive decline progresses.

Dementia and Testamentary Capacity: Key Considerations

Dementia encompasses a range of symptoms—memory loss, reduced reasoning skills, and compromised decision-making—worsening over time. Testamentary capacity is a legal standard requiring that the person making or updating a will:

• Understands the nature and effect of a will.
• Knows the extent of their assets (though not necessarily exact values).
• Comprehends who might have a moral claim to their estate (spouse, children, close dependants).
• Lacks any major delusions or illusions impacting their will decisions.

If an individual with dementia still meets these criteria at the time of signing the will, it may be upheld. However, if mental function is significantly impaired, the will could be challenged, especially by family members who suspect lack of capacity.

Signs of Capacity vs. Incapacity in Dementia

While a formal medical diagnosis indicates cognitive issues, it does not automatically equate to an inability to create a valid will. Dementia can progress gradually, and someone may have “good days” or “lucid intervals.” Lawyers and courts often look for evidence of capacity at the actual time of will signing. Below is a table illustrating some distinctions:

Note: A single off moment doesn’t always mean a total lack of capacity. Courts consider medical opinions, solicitor records, and witness statements together.

Ensuring a Will’s Validity: Practical Steps

Obtain Medical Assessment
When cognitive decline is present or suspected, it’s prudent to get a formal letter or capacity assessment from a GP, geriatrician, or psychologist near the time of will execution. This medical evidence can be critical if someone later disputes the will on grounds of mental incapacity.

Consult a Solicitor Skilled in Capacity Issues
Queensland solicitors frequently handle capacity checks by posing open-ended questions to gauge if the client grasps essential facts and can articulate rational reasons behind distributions. The solicitor’s file notes can help defend the will’s validity if challenged.

Ensure Proper Formalities
The testator must sign the will in the presence of two witnesses, who also sign. These witnesses should note if the testator appeared mentally clear and not coerced. If possible, avoid using major beneficiaries as witnesses to limit claims of undue influence.

Document Your Rationale
If your testamentary decisions appear unusual (e.g., favouring one child significantly more than others), attach a letter explaining why. This can help a court or beneficiaries understand you made a reasoned choice, offsetting any accusations of confusion or manipulation.

Challenges When Dementia Is Advanced

• If a doctor or lawyer deems the individual lacks capacity entirely, they cannot validly execute a new will. The existing will stands, or if none exists, intestacy rules apply.
• Families might consider alternative legal mechanisms such as an Enduring Power of Attorney (EPOA) to handle finances or property while the person with dementia is still alive but incapacitated. An EPOA cannot make or change a will on behalf of the person, but it ensures day-to-day decisions continue properly.
• In extreme cases, if the person never made a valid will and no capacity remains, loved ones might approach the Supreme Court for a statutory will—a court-ordered will for individuals who cannot create one themselves. The court attempts to reflect the person’s likely wishes based on available evidence.

Disputes and Court Proceedings

Beneficiaries or excluded family members can challenge a will, alleging:

• Lack of capacity: The testator’s dementia was so advanced they could not comprehend their actions.
• Undue influence: Another beneficiary exploited the testator’s cognitive decline for personal gain.

Under Queensland law, the court weighs medical records, solicitor notes, and witness testimonies about the testator’s mental state at the time of signing. If convinced the testator lacked capacity or was coerced, the court might invalidate the will wholly or in part, possibly reverting to a previous will or intestacy.

Tips for Queensland Families and Caregivers

Encourage Early Estate Planning
Once dementia progresses to moderate or severe stages, it may be too late to validly revise a will. Prompt updates while the person is still lucid can secure their testamentary intentions.

Get a Capacity Certificate
For individuals with mild cognitive impairment or early dementia, a professional assessment near the time of signing helps fend off future disputes.

Keep Transparent Communication
If the testator chooses unorthodox distributions, let them share (if comfortable) their reasons with close relatives to avoid shock or suspicion.

Use a Lawyer, Not a DIY Kit
In complex capacity scenarios, solicitors tailor the process carefully—asking capacity-relevant questions, gathering medical letters—minimising the likelihood of future legal challenges.

Consider Non-Legal Tools
Dementia’s progression can lead to daily living difficulties. Make sure to set up or update an Enduring Power of Attorney or an Advance Health Directive so that finances and medical care remain managed effectively.

Scenario: Mild Dementia but Intent to Change Will

Situation: Michael, aged 80, has an early-stage dementia diagnosis. He wants to alter his will so that each grandchild receives a specific bequest, though his prior will did not mention them. He visits a solicitor with a letter from his geriatrician stating he has mild cognitive impairment but still understands property management and key family relationships.

Process:

• The solicitor interviews Michael privately, asking him about his assets, beneficiaries, reasons for the new distributions.
• Michael lucidly identifies each grandchild, their personal circumstances, and the approximate estate assets, showing rational reasoning.
• The solicitor documents these findings, ensuring a second witness is present. Michael signs the updated will.

Outcome: If a disgruntled child challenges the will, Michael’s capacity is supported by the solicitor’s notes, the geriatrician letter, and the coherent conversation transcripts, making the new will more defensible.

Frequently Asked Questions

How can I tell if my parent with dementia still has capacity?
A formal assessment by a medical professional is best. A solicitor can also gauge mental clarity during discussions about estate details. If they can articulate their assets and beneficiaries rationally, they may still have capacity.

What if my loved one’s mental state fluctuates day-to-day?
Queensland courts look for capacity “at the time of execution.” If the will is signed during a lucid interval (and documented thoroughly), it may remain valid.

Can an attorney (under an EPOA) update the will on a dementia patient’s behalf?
No. An attorney cannot create or alter a principal’s will. They can handle finances or property within the attorney powers but not testamentary distributions.

Should the solicitor keep extra records when a client has dementia?
Yes. They often keep detailed file notes about the client’s understanding, mental status, and instructions—protecting the will from future capacity challenges.

Is it legal for family members to isolate a dementia patient to induce will changes?
That might be considered undue influence if it manipulates the testator’s free will. Courts look harshly on such tactics, which can invalidate the resulting will.

Key Takeaways & Summary

• Dementia doesn’t automatically render a person incapable of making or updating a will; what matters is their level of testamentary capacity at the signing.
• Early planning is vital. Making or revising a will while mental function remains sufficient helps avoid future dispute.
• Medical and solicitor evidence can bolster the will’s validity if contested.
• Queensland courts thoroughly examine alleged capacity issues, undue influence claims, and overall fairness.
• Family and caregivers should encourage timely estate planning plus consider EPOA or advanced directives for daily financial and health decisions.

Balancing legal compliance with a respectful approach to the complexities of dementia ensures the final will truly reflects the person’s final wishes, safeguarding both their autonomy and their family’s understanding of the estate decisions.
