In short

You can generally only revoke a power of attorney while you still have decision-making capacity. Signing the revocation is a legal act, but it takes practical effect only once third parties are told — there is no national register, so nobody finds out automatically. Notify the attorney, every bank, your super fund, registries and the titles office in writing.

Most estate planning advice is about getting documents in place. Very little of it is about taking one back — which is odd, because a power of attorney is the document you are most likely to need to change. It names a living person, and living people move overseas, get divorced from you, die, lose capacity themselves, or occasionally start helping themselves.

This article is about how to undo one, and more importantly about the part almost everyone gets wrong: signing a revocation is not the same as making it work.

It is general information, not personal financial advice, and it is not legal advice. Powers of attorney are made under state and territory law, and the rules genuinely differ — ASIC's MoneySmart puts it plainly: "Each state and territory has different rules for setting up a power of attorney" (https://moneysmart.gov.au/plan-for-your-retirement/wills-and-powers-of-attorney, as at August 2026). The formalities for revoking one differ too, so the specifics belong with a solicitor in your own state.

The window that closes

Start with the hard part, because it shapes everything else.

You can generally only revoke a power of attorney while you still have decision-making capacity. That is the same threshold that applies to making one — MoneySmart notes you must be "able to make your own decisions" when you create an estate plan, and that once capacity is lost, "you cannot put these arrangements in place."

So the document whose whole purpose is to protect you after capacity goes can only be undone before it. The window is open for as long as you can make your own decisions, and then it shuts.

The practical conclusion is not alarming, it is just administrative: your power of attorney needs reviewing on a schedule, the same way your will does, rather than sitting in a drawer for fifteen years. It belongs on the annual review list — our retirement plan review checklist is a reasonable place to anchor it. The best time to think about whether your attorney is still the right person is a long way before you need them.

Revoking is one document. Making it stick is a campaign

Here is the thing that surprises people.

Signing a revocation is a legal act. It is not, by itself, a practical one. The revocation produces its effect in the real world only once the people who might rely on the old document have actually been told — and nothing tells them automatically.

There is no national register of enduring powers of attorney in Australia. The Attorney-General's Department has been consulting on creating one, and separately on achieving greater consistency in enduring power of attorney laws across jurisdictions. Both of those consultations exist precisely because neither the register nor the consistency does. No central database gets updated when you sign a revocation. Nobody is notified on your behalf.

That matters more than it sounds, because of a general principle that runs through this area of law: a third party who deals with your former attorney in good faith and without notice that the appointment has ended is generally protected. The precise statutory form of that protection differs between jurisdictions, so treat it as the reason notice matters rather than as a rule to rely on. Either way the operative step is not the signature. It is the notice.

So the list below is not administrative tidiness. It is the part that does the actual work.

Who needs to be told

Work through this properly and keep a record of each notification — a copy of the letter, the date sent, and ideally proof of delivery.

Start with the attorney, in writing; if there is any prospect of a dispute, use a method that gives you proof of delivery rather than an email you hope was read. Tell any joint or substitute attorneys as well, since they were appointed under the same instrument and may not have heard from anyone.

Then work through the institutions. Every bank and credit union must be told separately — they do not share this between them — and if your attorney was recorded on accounts, ask for written confirmation the authority has been removed. Our article on getting a power of attorney accepted by the bank describes the process from the other direction; you are now undoing exactly that. The same goes for your superannuation fund and account-based pension provider, and for share registries and brokers.

Two more are easy to miss. If your power of attorney was registered with the land titles office — registration is required in some jurisdictions before an attorney can deal with property — check with your own titles office whether a revocation also needs to be lodged. And notify Services Australia, along with any other agency where the attorney has been dealing with your affairs. Finish with your aged care provider, accountant, solicitor and insurers, as applicable.

Keep this list with your household records rather than in your head — our article on the emergency information folder covers where that sort of thing should live.

The certified copy problem

Ask for the original document back. Then assume you have not solved the problem.

Powers of attorney circulate as certified copies. Your bank may hold one, your share registry another, the aged care provider a third. Retrieving the original does nothing about any of those, and a former attorney who kept a certified copy can still present it to somebody who has not been told.

This is the single most common reason a revocation fails to bite in practice, and it is why the notification list matters more than the document retrieval.

What does not end automatically

Several arrangements survive a revoked power of attorney, and people routinely assume otherwise.

Enduring guardianship and advance care directives are separate documents. A power of attorney generally covers financial and legal decisions; medical and lifestyle decisions usually sit in a different instrument with a different appointee. Revoking one does not touch the other — see our articles on enduring guardianship and on advance care directives for what those cover.

A Centrelink nominee arrangement is separate. It is made with Services Australia directly, not under your power of attorney, so it does not end when the power of attorney does. Cancel it separately with Services Australia — our article on Centrelink nominee and agent arrangements sets out how that appointment works.

Joint account access is separate. If you added someone to an account as a joint holder, their authority comes from the account, not from the power of attorney, and revoking the latter changes nothing. Our article on adding a child to your bank account covers why that arrangement is harder to unwind than people expect.

Do not assume a new power of attorney cancels the old one. Whether making a fresh appointment automatically revokes an earlier one varies between states — and even where it does, the bank holding a certified copy of the old one has no way of knowing that. Ask your solicitor, and notify everyone regardless.

If you think your attorney is misusing the authority

If money is missing, or transactions are appearing that you did not authorise, do not simply revoke quietly and hope it stops. Revoking closes the door going forward; it does nothing about what has already left, and it does not preserve the evidence.

Ring the bank first, or at the same time. Ask them to stop acting on the existing authority immediately and tell them why — do not wait until the revocation paperwork is finalised. Get the statements covering the whole period the attorney has been acting, before anything is tidied up, because you cannot assess what has happened without them.

And understand what this is. Misuse of a power of attorney by a family member is financial abuse, and depending on what has occurred it may also be theft. Our article on financial abuse and older clients covers the shape of it, including why it is so often a close relative and why it goes unreported for so long.

Get help, and get it from outside the family. The national elder abuse line is 1800 ELDERHelp — 1800 353 374 — a free call number that "automatically redirects callers seeking information and advice on elder abuse with the phone service in their state or territory" (Department of Health, Disability and Ageing, https://www.health.gov.au/contacts/elder-abuse-phone-line, as at August 2026). If your situation involves government-funded aged care, the Older Persons Advocacy Network runs the Aged Care Advocacy Line on 1800 700 600, which connects you with the aged care advocacy organisation in your state or territory (https://www.health.gov.au/contacts/older-persons-advocacy-network-opan-contact). A free financial counsellor can help you work through the financial damage, and a solicitor can advise on recovering money and on applying to the tribunal if that becomes necessary.

You are not being disloyal by asking questions. An attorney is required to act in your interests and to keep your money separate from theirs, and a person doing that properly will have no difficulty explaining the transactions — our article on an attorney's duties and responsibilities sets out what the role actually requires.

If capacity has already been lost

Then revocation is no longer available, and it becomes a matter for the civil and administrative tribunal in the relevant state or territory.

Broadly, these tribunals can review an enduring appointment, suspend or revoke it, and appoint a guardian or an administrator instead. An application can generally be made by a family member or another person with a proper interest — you do not have to be the attorney or the principal to raise a concern.

The process and the body differ in every jurisdiction, so this is one to take to a solicitor rather than work out from a website. But the important point is that the situation is not hopeless just because the window for revocation has closed.

Worked examples

Two readers arrive at this article for completely different reasons. Illustrative only, and not legal advice; formalities differ by state. No dollar figures appear here because nothing in this process turns on an amount — it turns on capacity, notice and timing.

Consider Margaret, 73, who separated from her husband eighteen months ago and has just realised he is still named as her attorney under an enduring power of attorney signed in 2011. Nothing has gone wrong; this is housekeeping. But three features of the process apply to her all the same. She can revoke it now because she has capacity, and that window will not stay open indefinitely. Signing the revocation will not tell her bank, her super fund or her share registry anything, because there is no national register to tell them. And her former husband may well hold a certified copy — so retrieving the original from the solicitor's file solves very little. On these facts, treating the notification list as the real task, and keeping proof of delivery for each one, is generally rational: the signature takes an afternoon, and the notices are what actually end his authority.

Now consider Frank, 81, who notices withdrawals from his account that he did not authorise and suspects the son he appointed as attorney. His instinct is to revoke quietly and avoid a scene. The difficulty is that revoking only closes the door going forward — it does not recover what has gone, and it does not preserve the record. On these facts, ringing the bank immediately to stop it acting on the existing authority, requesting statements covering the entire period his son has been acting before anything is tidied up, and calling 1800 353 374 for independent help outside the family are generally rational first steps, with the revocation paperwork following rather than leading. What has occurred may be financial abuse and may also be theft, and both of those are assessed on evidence that exists now and may not exist later.

The one-line version

Signing the revocation is the easy half. Until the bank, the fund, the registry and the titles office have each been told, the old document is still out there working — so treat the notification list as the actual task, and review the appointment while you still have the option.

Key takeaways

  • The window closes with capacity — a power of attorney can generally only be revoked while you can still make your own decisions, so review the appointment on a schedule rather than leaving it in a drawer.
  • There is no national register of enduring powers of attorney in Australia, so nothing notifies third parties on your behalf when you revoke one.
  • A third party dealing with your former attorney in good faith and without notice is generally protected — which makes notification, not the signature, the operative step.
  • Certified copies circulate. Getting the original back does nothing about the copies your bank, share registry and aged care provider each hold.
  • Enduring guardianship, Centrelink nominee arrangements and joint account access are all separate and do not end when a power of attorney is revoked.

Frequently asked questions

Can I revoke a power of attorney at any time?

Generally only while you still have decision-making capacity — the same threshold that applies to making one. That is why it is worth reviewing the appointment on a schedule rather than waiting until there is a problem. If capacity has already been lost, revocation is no longer available and it becomes a matter for the civil and administrative tribunal in your state or territory.

Is signing a revocation enough to stop my attorney acting?

Not on its own. A third party who deals with your former attorney in good faith and without notice that the appointment has ended is generally protected, and there is no national register that tells anyone. The revocation takes practical effect only once you have notified the attorney, your banks, your super fund, registries and the titles office in writing.

Does making a new power of attorney cancel the old one?

It varies between states and territories, so do not assume it. And even where a later appointment does revoke an earlier one, an institution holding a certified copy of the old document has no way of knowing that. Ask your solicitor about your own state, and notify everyone regardless.

What should I do if I think my attorney is taking my money?

Do not simply revoke it quietly. Contact your bank straight away and ask them to stop acting on the existing authority, get statements covering the whole period the attorney has been acting before anything is tidied up, and get help from outside the family. The national elder abuse line is 1800 ELDERHelp (1800 353 374), which redirects to your state or territory service.

Does revoking my power of attorney also end my Centrelink nominee arrangement?

No. A Centrelink nominee arrangement is made with Services Australia directly rather than under your power of attorney, so it continues until you cancel it separately. The same applies to enduring guardianship, advance care directives and joint account access — each is its own arrangement and needs its own cancellation.
