Capacity Assessment for Power of Attorney in Tasmania

A power of attorney signed by someone who lacks capacity is invalid — full stop. But capacity isn't a binary switch that flips from "has it" to "lost it." Early-stage dementia, post-surgical confusion, and medication side effects all create grey zones where the question isn't obvious.

What "Capacity" Means Under Tasmanian Law

To validly sign an enduring power of attorney in Tasmania, the principal must understand:

• The nature of the document — that they're granting someone authority over their financial affairs
• The scope of the authority — what the attorney will be able to do (particularly the difference between Form 3's restricted powers and Form 4's unrestricted powers)
• The consequences — that the attorney could misuse the power, and that the arrangement continues even after the principal loses capacity

Capacity is decision-specific and time-specific. A person might lack capacity to manage a complex investment portfolio but still have capacity to sign an EPOA appointing someone who can. A person might have capacity at 10 AM but not at 4 PM due to medication timing or fatigue (known as "sundowning" in dementia care).

Since the September 2024 amendments to the Guardianship and Administration Act 1995, Tasmania presumes all adults have decision-making capacity unless proven otherwise. This presumption supports signing where possible, rather than defaulting to "they can't."

When a Formal Assessment Is Needed

For a principal in good cognitive health, no medical assessment is required. The witnesses' statutory declaration — that the principal appeared to understand the document and signed voluntarily — is sufficient.

A formal medical capacity assessment becomes important when:

• The principal has a diagnosed cognitive condition — dementia, Alzheimer's, acquired brain injury, or intellectual disability
• There are observable signs of decline — repeated confusion, difficulty following conversations, inability to recall recent decisions
• Family tension exists — if other family members might later challenge the document's validity, a medical assessment on file makes it far harder to succeed
• The principal is in a care facility — where questions about undue influence are more likely to arise

How the Assessment Works

A capacity assessment for signing an EPOA is typically performed by:

• The principal's treating GP — the most common and accessible option
• A geriatrician — for more complex or contested cases
• A neuropsychologist — for formal cognitive testing when the GP's clinical judgment is borderline

The assessment should be:

1. Contemporaneous — conducted on or as close to signing day as possible. An assessment from six months ago doesn't prove the principal had capacity on the day they signed.
2. Documented in writing — a Health Practitioner Report or formal letter stating the clinician's opinion that the principal has (or lacks) the specific capacity to sign the EPOA.
3. Decision-specific — addressing whether the principal understands this particular document and its consequences, not just their general cognitive function.

The Legal Profession Board of Tasmania recommends that solicitors witnessing EPOAs for elderly or unwell principals make detailed contemporaneous file notes recording the principal's responses to capacity questions. Even for non-solicitor witnesses, writing down what the principal said and how they responded during the signing process provides a valuable record.

Protecting the Document From Future Challenges

If there's any risk that a family member might later argue the principal lacked capacity:

1. Get the GP assessment in writing before signing day. Keep the original with the EPOA.
2. Choose one professional witness. Having a solicitor, JP, or medical practitioner as one of the two witnesses adds professional credibility to the execution.
3. Record the principal's understanding. Before the signing, ask the principal to explain in their own words what the document does and who they're appointing. Write down their answers, date them, and have the witnesses sign the note.
4. Avoid signing during "bad" periods. If the principal has dementia, schedule the signing for their best time of day — typically morning, before fatigue or sundowning sets in.
5. Don't rush. Give the principal time to read the document, ask questions, and confirm their choices. Pressure or hurry undermines the voluntary requirement.

What Happens When Capacity Is Lost

If the principal has already lost cognitive capacity, it's too late to sign a new EPOA. The family's only option is to apply to TASCAT for an administration order (for financial decisions) or a guardianship order (for personal and medical decisions).

This process involves:

• Obtaining a Health Practitioner Report confirming the person lacks capacity
• Filing a TASCAT application (no application fee)
• Serving formal notices on the represented person and close family members
• Attending a TASCAT hearing (often via teleconference)
• Receiving and complying with ongoing TASCAT orders and reporting requirements

TASCAT may appoint a family member, the Public Trustee, or the Public Guardian — depending on who's available and suitable. The process takes weeks to months and imposes ongoing oversight that a private EPOA arrangement avoids.

The Practical Takeaway

If you're reading this because your parent has been diagnosed with early cognitive decline, the capacity window may still be open — but it won't stay open indefinitely. The Tasmania Power of Attorney Kit includes a capacity assessment preparation guide and a signing-day protocol designed to create the strongest possible record of valid execution, so the documents hold up if they're ever challenged.
