Enduring Power of Attorney in Western Australia

By Jonathan Crabtree · 20 August 2025 · 7 min read

An Enduring Power of Attorney (EPOA) is a legal document that appoints someone you trust—called an attorney—to make financial and property decisions on your behalf if you lose mental capacity. Unlike a general power of attorney, which ceases when you lose capacity, an EPOA 'endures' beyond incapacity. Without one, your family may need to apply to the State Administrative Tribunal (SAT) for guardianship and administration orders, a process that is slow, costly, and public.

What Is an Enduring Power of Attorney?

An EPOA is governed by the Guardianship and Administration Act 1990 (WA). It allows you to appoint one or more attorneys to manage your financial and legal affairs when you are unable to do so yourself—whether due to dementia, stroke, accident, or any other condition that impairs your decision-making capacity.

The key feature of an EPOA is that it continues to have effect even after you lose capacity, whereas a general power of attorney automatically ceases at that point. An EPOA can be drafted to take effect immediately (giving your attorney authority now) or only when you lose capacity (a 'springing' EPOA). Most people opt for the immediate form but rely on trust that the attorney will not exercise the power unless necessary.

An EPOA is distinct from an Enduring Power of Guardianship, which appoints someone to make personal and lifestyle decisions (such as medical treatment and accommodation). Both documents are essential for comprehensive incapacity planning in Western Australia.

Financial vs Personal/Health Decisions

It is important to understand the distinction between financial powers and personal/health powers, as they are governed by separate documents in Western Australia:

  • •Enduring Power of Attorney (EPOA): Covers financial and property matters—banking, paying bills, selling property, managing investments, operating a business, lodging tax returns, and dealing with government agencies like Centrelink.
  • •Enduring Power of Guardianship (EPG): Covers personal and lifestyle decisions—medical treatment, accommodation, services, and day-to-day care. Does not cover financial matters.

You need both documents for complete protection. An EPOA alone does not give your attorney the power to consent to medical treatment or decide where you live. An EPG alone does not allow your guardian to manage your bank accounts or pay your bills. Most people appoint the same trusted person as both attorney and guardian, but you can appoint different people if appropriate.

When It Takes Effect

An EPOA can be structured to take effect in one of two ways:

  • •Immediate: The attorney has authority to act from the moment the EPOA is signed and registered. This is the most common form in Western Australia because it allows the attorney to step in seamlessly if capacity is lost suddenly. You retain the ability to manage your own affairs as long as you have capacity, and the attorney acts alongside you or at your direction. Trust is essential.
  • •Springing (upon incapacity): The attorney's authority is triggered only when you lose capacity, as certified by a doctor or tribunal. This offers greater control but can create delays and uncertainty—banks and institutions may require medical evidence or tribunal orders before accepting the attorney's authority.

Most legal practitioners in WA recommend immediate EPOAs combined with clear safeguards and trusted attorneys. The alternative—waiting until capacity is lost—can result in frozen accounts, unpaid bills, and administrative gridlock at the worst possible time.

How to Make One in Western Australia

Creating an EPOA in Western Australia involves four key steps:

  1. 1.Choose your attorney(s): Select someone you trust implicitly to manage your finances in your best interests. This is typically a spouse, adult child, or close family member. You can appoint joint attorneys (who must act together) or joint and several attorneys (who can act independently). Consider appointing a substitute attorney in case your first choice is unable or unwilling to act.
  2. 2.Draft the document: Use the prescribed form or have a lawyer draft a tailored EPOA. The document must clearly specify when it takes effect (immediate or springing), what powers are granted, and any restrictions or conditions. Common restrictions include prohibiting gifts above a certain value or requiring multiple attorneys to act jointly for major transactions.
  3. 3.Sign and witness: You must sign the EPOA in the presence of two witnesses (or one authorised witness such as a lawyer or justice of the peace). The attorney must also sign, accepting the appointment. Witnesses cannot be your attorney, their spouse, or a relative.
  4. 4.Register and notify: While registration is not mandatory, it is strongly recommended. Registered EPOAs are recorded with Landgate (if they relate to property) or can be registered with financial institutions. Provide certified copies to your attorney, family members, and relevant banks or advisers.

Legal advice is strongly recommended when preparing an EPOA. A lawyer will ensure the document complies with WA law, addresses your specific circumstances, and includes appropriate safeguards. The cost is modest—typically $300 to $800—but the protection it provides is invaluable.

What Happens Without One

If you lose mental capacity without an EPOA in place, no one—not even your spouse—has automatic authority to manage your finances. Your family must apply to the State Administrative Tribunal (SAT) for an administration order, which appoints someone to manage your affairs. This process is:

  • •Slow: SAT applications take 3 to 6 months, during which time your assets may be frozen and bills unpaid.
  • •Costly: Legal fees, medical reports, and tribunal filing fees can exceed $5,000. The appointed administrator may also charge ongoing fees.
  • •Public: SAT proceedings are a matter of public record, and the tribunal may impose restrictions or oversight that you would not have chosen.
  • •Uncertain: The tribunal may appoint someone other than your preferred family member, or appoint the Public Trustee, a government agency that manages estates for a fee.

All of this can be avoided with a properly drafted EPOA. It is one of the simplest and most effective tools for protecting yourself and your family from bureaucratic delay and expense.

Revoking an Enduring Power of Attorney

You can revoke (cancel) your EPOA at any time, as long as you have mental capacity. Revocation must be done in writing, signed, and witnessed in the same manner as the original EPOA. You should notify your attorney, any institutions holding copies (banks, lawyers), and destroy the original document.

If your attorney dies, becomes bankrupt, or is no longer suitable, the EPOA automatically ceases unless you appointed a substitute attorney. You should review your EPOA every few years—particularly after major life events such as marriage, divorce, or the death of your attorney—to ensure it remains appropriate.

If you no longer have capacity, you cannot revoke the EPOA yourself. However, a concerned family member or the attorney themselves can apply to SAT to have the EPOA reviewed or revoked if there is evidence of abuse, conflict of interest, or mismanagement.

An Enduring Power of Attorney is an essential component of any estate plan. It ensures your financial affairs are managed by someone you trust if you lose capacity, avoiding tribunal intervention and protecting your family from unnecessary stress. If you don't yet have an EPOA, speak with a lawyer and put one in place while you still can.
