How to Revoke Power of Attorney or Enduring Guardian in NSW

You Can Revoke at Any Time — While You Have Capacity

If you have decision-making capacity, you can revoke any of your planning documents unilaterally. No one else's consent is required, and you do not need to provide reasons. The critical requirement is that the revocation must be communicated clearly and documented properly so there is no ambiguity about which version of your documents is current.

The rules differ slightly depending on which document you are revoking, because each one operates under different legal authority in NSW.

Revoking an Enduring Power of Attorney

Under the Powers of Attorney Act 2003 (NSW), you revoke an enduring power of attorney by executing a written revocation instrument. The revocation must be witnessed by a prescribed witness — the same category of witness required for the original EPOA (Australian legal practitioner, Local Court registrar, licensed conveyancer who has completed the approved course, approved NSW Trustee & Guardian or trustee-company employee who has completed the approved course, or qualified foreign legal practitioner).

After signing the revocation, you must notify the attorney in writing that their authority has been terminated. If the power of attorney was registered with NSW Land Registry Services, you must also lodge a revocation with the registry. Until the registry is updated, third parties dealing with the attorney in good faith are protected — meaning your former attorney could theoretically complete a property transaction before the revocation is recorded.

The practical steps are straightforward: draft a revocation document that references the original power of attorney by date, have it witnessed by a prescribed witness, serve a copy on the attorney, and lodge the revocation with Land Registry Services if the original was registered.

Revoking an Enduring Guardian Appointment

The process under the Guardianship Act 1987 is similar but not identical. You must execute a written revocation using the statutory form and have it witnessed by a prescribed witness. The revocation is legally ineffective until written notice has been delivered to the guardian, so failing to notify the guardian promptly creates practical problems because they may continue acting under the belief that they still hold authority.

If you want to revoke the appointment and replace it with a new guardian, you can do both in a single transaction. The new appointment of enduring guardian implicitly revokes any prior appointment for the same functions, provided the new appointment is validly executed and witnessed.

If you have lost capacity and your family believes the enduring guardian is not acting in your best interests, they cannot simply revoke the appointment themselves. Instead, they must apply to the Guardianship Division of NCAT to have the appointment reviewed. NCAT can revoke the appointment, substitute a different guardian, or impose additional conditions. These applications have no filing fee, but complex, contested cases can take six to twelve months to resolve.

Revoking or Updating an Advance Care Directive

Because NSW advance care directives operate under common law rather than a statute, there are no formal procedural requirements for revocation. You can revoke your directive orally, in writing, or by destroying the document. Creating a new advance care directive implicitly revokes any earlier version, provided the new one is clearly dated.

The practical concern is ensuring that every person who holds a copy of the old directive receives the updated version. If your GP's file still contains the 2019 version of your directive while your family holds the 2026 version, there is a genuine risk that the outdated instructions will be followed in an emergency. After updating your directive, send the new version to everyone who received a copy of the old one: your GP, your enduring guardian, your specialists, and your My Health Record.

If you uploaded your directive to your federal My Health Record, log in and replace the old PDF with the new version. Delete or clearly mark the superseded document to prevent confusion.

When Revocation Gets Complicated

The most common dispute arises when family members disagree about whether the principal still has capacity to revoke. If your daughter wants to revoke your enduring guardian appointment and your son (the current guardian) argues that you lack the capacity to make that decision, the dispute must be resolved by NCAT. The tribunal will review the appointment and make a determination.

Another complication: if you revoke your planning documents but do not replace them, you leave a gap. If you later lose capacity without a current enduring guardian or power of attorney, your family will need to apply to NCAT for a guardianship or financial management order — a process that is slower, more expensive, and more adversarial than a voluntary appointment.
