Challenging Power of Attorney Australia

You think the appointed attorney is mismanaging your parent's money. Or a sibling got themselves named as sole attorney and is cutting everyone else out of care decisions. You want to challenge the arrangement — but you're not sure whether you have standing, what grounds are valid, or how the tribunal process actually works.

Challenging an EPOA in Australia is a serious legal step, but it's one the system explicitly allows. Every state tribunal has a guardianship division designed to handle exactly these disputes.

Who Can Challenge an EPOA

Any "interested person" can apply to the tribunal for a review of an enduring power of attorney. This includes the principal (if they retain capacity), any family member, a friend or carer with a genuine interest in the principal's welfare, a social worker, a medical professional involved in the principal's care, and the Public Guardian or Public Advocate.

You don't need to be named in the EPOA. You don't need to be the closest relative. You do need a genuine concern about the principal's welfare — tribunals will dismiss applications that are clearly motivated by family politics rather than the principal's interests.

Grounds for Challenge

The principal lacked capacity when they signed. If the principal didn't understand the nature and effect of the EPOA at the time of execution — perhaps because dementia had already progressed beyond the capacity threshold, or because they were under the influence of medication — the document may be void. You'll need medical evidence from around the time of signing.

The attorney is acting improperly. Financial mismanagement is the most common ground: the attorney is spending the principal's money on themselves, making risky investments, failing to pay bills, or refusing to account for transactions. Personal care concerns may also be relevant where the instrument gives the attorney personal powers, or where a related guardianship appointment is under review.

The attorney has a conflict of interest. The attorney is making decisions that benefit themselves at the principal's expense — for example, selling the principal's property to themselves below market value, or choosing an aged care facility based on its proximity to the attorney rather than its quality of care.

The attorney is incapable. The attorney's own health has deteriorated, they've moved overseas, or they simply can't manage the responsibilities. An EPOA doesn't work if the person holding the authority can't exercise it.

Undue influence or coercion. The principal was pressured or manipulated into signing the EPOA, or the attorney is using their position to coerce the principal's ongoing decisions.

The Tribunal Process

File an application with the guardianship division of your state tribunal. The application is free in every Australian jurisdiction:

NCAT (NSW), VCAT (Victoria), QCAT (Queensland), SAT (Western Australia), SACAT (South Australia), TASCAT (Tasmania), ACAT (ACT), NTCAT (Northern Territory).

The tribunal will notify all interested parties — including the attorney being challenged — and schedule a hearing. At the hearing, you'll present your evidence (financial records, medical reports, witness statements), and the attorney will have the opportunity to respond.

Tribunals are less formal than courts. You can represent yourself, and the rules of evidence are relaxed. But the standard of proof is still substantial: you need more than suspicion or family disagreement. You need documented evidence that the attorney's conduct is harming or risking the principal's welfare.

What the Tribunal Can Do

If the tribunal finds the challenge is justified, it can make orders addressing the person's personal and/or financial decision-making, including changing who is appointed or appointing the Public Trustee or Public Guardian if no suitable family member is available. The exact powers and conditions vary by jurisdiction.

The tribunal can also dismiss the application if the evidence doesn't support the claim. Dismissed applications don't automatically penalise the applicant, but repeated unfounded applications may be treated as vexatious.

Reviewing Existing Tribunal Orders

If a guardianship or administration order is already in place (rather than an EPOA), the same tribunal process applies. Any interested person can apply to review the order. Tribunals periodically review their own orders, but an interested person can request an earlier review if circumstances have changed.

Before You File

Consider whether informal resolution is possible first. If the dispute is between siblings about care decisions rather than actual misconduct, family mediation may resolve the conflict without a tribunal hearing. Many community legal centres offer free or low-cost mediation for elder law disputes.

If you genuinely believe the attorney is mismanaging funds or neglecting the principal's welfare, don't wait. Financial abuse escalates, and the longer it continues, the more difficult it is to recover assets.

The Enduring Power of Attorney and Guardianship toolkit covers the tribunal application process for all eight jurisdictions — including evidence checklists and what to expect at the hearing.
