Need an enduring power of attorney in NSW? Learn the difference between a general POA, who can witness it, and how capacity works. Read our Sydney legal guide.

r you lose capacity. That’s the whole point of it. It’s the document you sign before anything goes wrong, so someone you trust can manage things when it does.

Most people who come to us asking for an “EPoA” have been told they need one, often by a GP, sometimes by a family member after a fall, and whoever raised it is almost always right. A general POA is convenient for short-term tasks. An enduring POA is the one that actually protects you in the scenarios people don’t like thinking about.

When does an enduring power of attorney start, and when does it end? 

You choose when your enduring POA starts. Most people pick “immediately” on the view that a trusted attorney can sit on the sidelines until they’re needed. Others prefer a trigger, usually a medical opinion that capacity’s been lost, or a specific future date. The immediate option is simpler to administer and doesn’t require a doctor to certify incapacity before anyone can act on your behalf.

A general POA usually starts the day it’s signed. It ends when the job it was created for is done, or when the set date passes, or the moment capacity is lost, whichever comes first.

Both documents end when you die. After that, making a will ensures your chosen executor takes over, and the POA has no further authority. One of the more common misconceptions is that an attorney can keep operating accounts after death. They can’t. The authority dies with the principal, and the executor, if there’s a will, takes over from there.

What does “capacity” mean for a power of attorney in NSW? 

Capacity, in the legal sense, has a specific meaning. It’s the ability to understand the information behind a decision, to weigh up what the options actually mean for you, and to communicate the choice you’ve made. The Powers of Attorney Act 2003 (NSW) starts from the presumption that adults have capacity; the burden sits on whoever’s arguing otherwise.

What capacity isn’t: a fixed status. You might have the capacity to decide where to live, but not to manage a share portfolio. It can come and go, dementia progresses in waves, and someone having a bad day in the hospital might have a clear one a week later. The question is always decision-specific and time-specific.

If you’ve signed an enduring power of attorney, a loss of capacity is the moment it starts doing its real work. Your attorney steps in to run the day-to-day money side — bills, bank dealings, super and Centrelink paperwork. Whatever was your job yesterday becomes theirs today.

If you haven’t signed one and capacity’s lost, nothing moves. Your bank accounts are still yours, but nobody has legal authority to operate them. The family’s only option is an NCAT application for a financial management order under the NSW Trustee and Guardian Act 2009 (NSW). NCAT can appoint a family member as financial manager or the NSW Trustee and Guardian directly.

Who can witness an enduring power of attorney in NSW? 

A general POA needs one adult witness. Any competent adult will do, provided they aren’t an attorney under the document themselves.

An enduring POA is different. It needs a prescribed witness, someone from a short statutory list, who signs a certificate on the form confirming they explained the effect of the document and that you appeared to understand it. Without that certificate, the document has no enduring effect. It’s the single most common technical failure we see in DIY POAs that clients bring in after the fact.

Prescribed witnesses under the Act include solicitors and barristers, registrars of a Local Court, licensed conveyancers, and certain authorised staff of the NSW Trustee and Guardian. A family member can’t witness your enduring POA, even an adult one with no involvement in the document, because the role is reserved for an independent professional who can certify your understanding.

Do you have to register a power of attorney in NSW? 

Not to make it valid. A properly signed and witnessed POA works from the moment it’s signed, whether or not it’s registered anywhere.

Registration becomes necessary when the attorney signs a dealing that affects NSW land, such as a sale, transfer, or mortgage. NSW Land Registry Services won’t accept the dealing for registration unless the underlying power of attorney has been registered first. Plenty of attorneys get caught by this at settlement, having to delay transactions while the registration goes through.

Registration has practical advantages even where land isn’t involved. The POA becomes a public document, which makes it easier for banks and other third parties to accept without further enquiry. Banks are sometimes cautious with unregistered POAs. It’s not always strictly correct of them, but they’d rather see the public record. Where your attorney’s going to be dealing with significant assets, the filing fee is worth paying.

Can a power of attorney make medical decisions in NSW? 

No. A power of attorney, general or enduring, covers financial and legal decisions only. Medical and lifestyle calls, where you live, what care you consent to, fall to an Enduring Guardian, appointed separately under the Guardianship Act 1987 (NSW).

This is one of the biggest misconceptions about POAs. People sign one thinking they’ve covered everything and only find out later, often when a spouse goes into the hospital, that their attorney can’t consent to surgery or make the call on residential aged care. Those decisions rest with an Enduring Guardian if you’ve appointed one, or with a default list of relatives under the guardianship legislation if you haven’t.

If you want the same person handling both sides, they need both appointments. Most people do both at the same time, usually naming the same person as attorney and guardian. The documents sit next to each other in the file.

Can you have more than one attorney? 

Yes, and the way you set up the appointment changes the practical effect significantly.

Joint attorneys have to act together on every decision. That builds in checks and balances, because nothing happens without agreement. It also means if one attorney is overseas or in the hospital, nothing can be done. For anything time-sensitive, joint appointments slow things down.

Joint and several attorneys can each act independently, without needing the other’s sign-off. That’s far more flexible; one can handle banking while the other deals with Centrelink, but it relies on both being trustworthy and communicating well. Either of them can, in theory, sign a dealing the other doesn’t know about.

Substitute attorneys are the backup. They only step in if the primary attorney can’t continue, most commonly where the primary has died or resigned from the role. Most well-drafted enduring POAs name at least one substitute. It costs nothing to include and saves a serious problem down the line.

What safeguards should you build into an enduring power of attorney? 

An attorney’s a fiduciary. They have to act in your best interests, keep proper records, and avoid conflicts of interest. Most attorneys do the right thing. A small but consistent fraction don’t, and an enduring POA in the wrong hands gives them serious tools to cause damage.

Good drafting reduces that risk. The safeguards we include in enduring POAs for clients with substantial assets or blended families cover:

• Gift limits — a cap on what the attorney can give away, to themselves, to charity, or to other family, without separate authority
• Separate funds — a requirement that the attorney keep your money in an account separate from their own
• Second signature thresholds — for transactions above a set amount, another nominated person has to approve
• Accounting obligations — a requirement to produce regular written accounts to a named family member or adviser
• No-benefit clauses — the attorney can’t transfer assets to themselves or benefit from transactions unless the document expressly allows it

These aren’t in the standard NSW POA form. Most off-the-shelf documents contain none of them. If you want them included, they need to be drafted specifically — and the drafting needs to come from someone who’s seen how attorneys actually go wrong.

How do you cancel or revoke a power of attorney in NSW? 

You can revoke a POA at any time, provided you still have capacity. The revocation has to be in writing and needs to go to:

• The attorney, ideally, by registered post, so there’s proof of service
• Any bank, financial institution, or third party you know to hold a copy
• NSW Land Registry Services, if the POA was registered there

A revocation that isn’t properly communicated is almost as bad as no revocation at all. If your bank still holds the earlier document and has no notice of cancellation, they’ll keep accepting transactions from your former attorney in good faith. The law’s on your side once the notice is given. The practical mess in the meantime isn’t.

Where you don’t have capacity yourself, you can’t revoke a POA on your own. The only route is an NCAT application asking the Tribunal to revoke the appointment, usually brought by a family member, and typically where the attorney is misusing their authority.

What if the attorney is misusing their authority? 

Misuse of enduring POAs is one of the fastest-growing categories of elder financial abuse in NSW. The pattern’s usually the same. An adult child or long-term carer holding the EPoA starts drawing on the principal’s accounts for their own benefit, or selling assets to related parties below market value. The principal, often already in aged care, doesn’t find out for months.

Red flags worth taking seriously:

• Unexplained withdrawals or sudden changes in banking patterns
• Unpaid bills despite available funds in the principal’s accounts
• The principal being isolated from other family members or advisers
• Sudden transfers of real estate or shares without clear justification

If you suspect misuse, start with legal advice. The bank can freeze accounts pending an application. An NCAT application under the Powers of Attorney Act can revoke the attorney’s appointment and put proper financial management orders in place. Where money’s been taken, civil recovery proceedings can follow. In serious cases, theft from a principal by an attorney is a criminal offence prosecutable by NSW Police.

Delay is the attorney’s friend in these matters. The sooner an application’s made, the more that’s recoverable.

Where powers of attorney meet family law 

Most of the disputed POAs we see at Hillcrest sit in two places.

The first is separation. A client gave their spouse an EPoA in 2015, separated in 2023, and didn’t update anything. Under NSW law, a marriage separation doesn’t automatically revoke the appointment. Neither does applying for divorce later, nor signing a binding financial agreement. The ex-spouse stays the attorney until actively revoked. If relations have turned bitter, that’s a live risk, and the revocation needs to happen the day the separation becomes permanent, not after property settlement is done.

The second is blended family disputes over ageing parents. The second spouse holds the EPoA. Adult children from a first marriage disagree with decisions being made about their parents’ care or money. Those matters end at NCAT more often than anywhere else, with competing applications to revoke the EPoA or to install a financial management order in its place.

There’s a quieter pattern too. One spouse is the attorney for the other under a long-standing EPoA, usually the one who ran the business or the investments. Separation starts, property settlement hasn’t formally begun, and the attorney-spouse starts moving assets under the authority they still technically hold. Reversing those transactions means a Family Court application under s106B of the Family Law Act 1975. It’s winnable. It’s also slow and costly, and the asset pool’s smaller by the time it’s done.

A power of attorney is easy to sign and hard to undo once it’s being misused. The general version handles short-term practical needs. The enduring one carries you through the parts of life where you’re least able to look after yourself. The people you appoint and the limits you build into their authority both matter, and the document sits alongside your will, and any broader estate planning, a testamentary approach that might include a testamentary trust for blended-family circumstances, works best when the POA is consistent with it.

If there’s a separation on the horizon or a parent whose capacity is starting to fail, the POA conversation belongs alongside the family law one.
