Separation does not revoke an enduring power of attorney in NSW. An enduring power of attorney granted to a spouse during the marriage stays in force after separation. It also survives a divorce order, a binding financial agreement, and any property settlement reached without a separate step being taken to revoke it. Only a written revocation, properly prepared and communicated, brings the appointment to an end.

This catches separating couples in NSW more often than almost any other estate planning oversight. The original signing usually happened years earlier, often when buying a house or making a will. By the time the relationship ends, the document itself has often been forgotten. The legal authority it confers on your former partner continues to operate regardless.

For anyone moving through a separation in NSW, revocation of any enduring power of attorney granted to a former spouse belongs at the top of the administrative list.

Key Takeaways

• An enduring power of attorney granted to a spouse continues to operate after separation, divorce, and property settlement.
• A former partner who remains your appointed attorney can still operate accounts and sign documents in your name. If the power extends to real property, they can deal with that too.
• Revocation requires a written instrument of revocation. The instrument has to be served on the former attorney, and where the power was registered with NSW Land Registry Services, the revocation needs to be registered as well.
• If your former partner has already used the power of attorney during the separation to move assets, those transactions may be reversible. Section 106B of the Family Law Act 1975 is the most common path to setting them aside.
• The revocation belongs alongside the other administrative tasks taken early in a separation, including review of the will, reconsideration of any superannuation binding death nomination, and reassessment of the enduring guardian appointment.

Why Doesn’t Separation Affect a Power of Attorney in NSW?

The Powers of Attorney Act 2003 (NSW) sets out when a power of attorney ends. The terminating events are limited. The death of the principal terminates it. Written revocation while the principal still has capacity terminates it. An order of the NSW Civil and Administrative Tribunal can terminate it. None of those triggers is activated by separation or by divorce.

This is different from how some other estate documents are treated. Wills can be partially affected by divorce under the Succession Act, with gifts to a former spouse treated as revoked in defined circumstances. Powers of attorney sit outside that framework. The legal authority you granted is to the person, not to the relationship, and the document does not care whether you are still living together.

The reasoning behind the legislation is practical. Powers of attorney are relied on by third parties: banks, conveyancers, accountants, and share registries. If the document’s validity depended on the state of a marriage, every institution dealing with an attorney would need to verify the principal’s marital status before acting. Such a requirement would undermine the workability of the system. The protection against misuse sits elsewhere, in the fiduciary duty owed by the attorney and the principal’s right to revoke at any time while they have capacity.

What Can a Former Spouse Attorney Still Do?

The practical reach is broader than most clients expect when they first ask the question.

A former spouse who holds an unrevoked enduring power of attorney can operate any account named in the document, or any account the document gives general financial authority over. They can sign correspondence and authorisations in your name. Where the power extends to real property, they can sign dealings that affect that property, including transfers and mortgages, provided the power has been registered with NSW Land Registry Services. Reach can extend to superannuation accounts, share portfolios, or a business interest, depending on what the original document was drafted to allow.

Whether your former partner will use the authority is a separate question. In a significant proportion of separations, no use is ever made of the power, even where revocation has been overlooked entirely. Where the matter is contested, however, and particularly where the property settlement remains unresolved, or one party considers themselves financially disadvantaged, the unrevoked authority presents a material risk.

A client came in seven months into a separation, having discovered that her former husband had used the power of attorney to redirect rental income from a jointly owned investment property into an account in his sole name. The transactions were defensible on paper because the power gave him the authority to sign them. Recovering the funds and restoring the position took longer than the original separation negotiations.

How to Revoke an Enduring Power of Attorney After Separation in NSW

Revocation is not a difficult process, but it has to be executed properly. A verbal instruction does not end the appointment, and informal written communication directed to the attorney or to third parties has no legal effect on the authority granted.

The revocation needs to be in writing. It should identify the original power of attorney by date and the parties to it, state clearly that the power is revoked, and be signed by the principal in the presence of a witness. Most NSW solicitors hold standard forms for this purpose and can prepare and witness one in a single appointment.

The instrument must be served on the former attorney. Registered post is the standard approach because it generates evidence of delivery, which matters if the former attorney later signs something using the original authority. Email may suffice in some circumstances, but is harder to prove later.

Banks, financial institutions, accountants, share registries, and any other third party that holds a copy of the original power should be notified separately. Banks will generally require a copy of the revocation and may ask the principal to attend in person to confirm. Where the original power was registered with NSW Land Registry Services, the revocation has to be registered there as well. Without that registration, dealings affecting NSW land could still be accepted on the basis of the original registered authority.

The principal needs to have the capacity to revoke. Where capacity is lost or in dispute, the only path to ending the appointment is an application to NCAT. That route is slower and more public, and the timing is no longer in the principal’s hands.

What If My Ex Has Already Used the Power of Attorney During Separation?

This is where the matter moves from estate planning into family law, and where the cost of recovery typically exceeds the cost of timely revocation by a substantial margin.

The starting point is identifying what has been done. Bank statements, conveyancing records, accountant correspondence, and Land Registry searches all become relevant. The transactions need to be mapped, dated, and characterised before any application is made.

The most common path to reversing the transactions is section 106B of the Family Law Act 1975, which allows the Federal Circuit and Family Court of Australia to set aside dispositions made to defeat a party’s claim in property settlement proceedings. The provision is not limited to transactions made under a power of attorney, but it is the cleanest route where an attorney-spouse has moved assets during separation. The court can also restrain further dispositions through injunctive relief while the main matter is being heard.

Where the conduct moves beyond moving assets and into outright misappropriation, NCAT can revoke the appointment and put a financial management order in place. Recovery of misappropriated funds is a separate civil proceeding. In serious cases, where the attorney has knowingly taken property belonging to the principal, the conduct can constitute a criminal offence prosecutable by NSW Police.

These outcomes are achievable. They are also costly and time-consuming, and represent expenditure that timely revocation would have rendered unnecessary. The substantially cheaper position is a written revocation, signed and served in the week the separation becomes final.

Where Revocation Fits in the Separation Timeline

The administrative side of separation in NSW is often deferred while parenting, accommodation, and the property pool take immediate attention. The risk in that sequencing is that the documents giving your former partner authority over your affairs sit untouched while everything else is being negotiated.

Our standard advice for clients beginning a separation covers four documents in the first month. The will is one. Most wills drafted during a marriage name the spouse as primary beneficiary and executor, and continuing with that arrangement after separation is rarely what the principal would now choose. The superannuation binding death benefit nomination is the second. These nominations are often pointed at the spouse and cover what is, for many people, the largest single asset they hold. The enduring guardian appointment is the third. The enduring power of attorney is the fourth.

None of these documents are revoked by the act of separation itself, and each requires its own positive step on the part of the principal.

Common Misconceptions About Powers of Attorney After Separation

Many clients arrive believing that lodging an application for divorce or signing a binding financial agreement ends the power of attorney by operation of law. It does not. The documents sit in different statutes and do not cross-reference.

Others assume that the principal can simply tell the bank to stop accepting the attorney’s authority. Banks will sometimes flag the account and require additional verification on the basis of an informal instruction, but the underlying legal authority remains in place until the power is properly revoked. The bank’s caution is not a substitute for revocation.

In amicable separations, the more common view is that revocation is unnecessary because the former partner would never use the authority. The difficulty with that view is that the circumstances of an amicable separation rarely hold still. A new partner enters the picture, financial pressures change, fresh advice comes from outside the original relationship, and what felt safe at the point of separation no longer is. The appointment that posed no risk when signed continues to operate regardless of how the relationship has shifted.

If you are separating in NSW and your former partner holds a power of attorney over your affairs, book a confidential consultation with our family law team. The revocation itself is a brief instrument to prepare in isolation. We can review it alongside your will, your superannuation nomination, your enduring guardian appointment, and any property settlement steps already underway.

Frequently Asked Questions

Does divorce automatically revoke a power of attorney in NSW? 

A divorce order does not end any power of attorney granted during the marriage. The Powers of Attorney Act 2003 (NSW) does not list divorce among the events that bring an appointment to an end. The marriage ends; the power of attorney granted to the former spouse continues to operate. Revocation has to be done separately, in writing, and served on the former attorney before the authority comes to an end.

Can my ex sell my house under power of attorney after separation? 

Possibly. The answer depends on how the original power was drafted and whether it was registered with NSW Land Registry Services. A power authorising the attorney to deal with real property, and properly registered, would, in theory, allow a sale to proceed. Conveyancers and buyers’ solicitors will often pick up the separation context and raise enquiries, but reliance on that is not safe. Revoking the power and registering the revocation is the protective step.

How long does it take to revoke a power of attorney in NSW? 

The revocation instrument itself takes a single appointment to prepare and sign. Service on the former attorney and notification to banks and other institutions can be completed within days. Where the original power was registered with NSW Land Registry Services, registration of the revocation usually takes a week or two, depending on the lodgement queues. The full process is typically finished within two to three weeks.

Do I need a lawyer to revoke a power of attorney after separation? 

There is no legal requirement to engage a lawyer. A properly drafted revocation is a short document, and a principal who understands what needs to go into it can prepare one without representation. The reason most clients choose to use a solicitor is the consequence of a defect: a former attorney who later disputes service, or argues the revocation was not validly executed, can leave the principal exposed to transactions that should never have been possible. Where the separation involves real property, a former spouse with strong financial motivation, or any prospect of contested property settlement, legal preparation reduces a real risk to a small fixed cost.

What if my ex won’t accept the revocation notice? 

Acknowledgement by the former attorney is not required for the revocation to take effect. What is required is proper service. The revocation operates from the point at which service has been properly effected, regardless of whether the former attorney acknowledges receipt. The relevant banks and other third parties should be notified at the same time so that the original document is no longer relied on.
