Enduring Power of Attorney South Australia: A Plain-English Guide

When someone loses the ability to manage their own finances — through dementia, a stroke, or a serious accident — banks freeze accounts, bills go unpaid, and property cannot be sold without court intervention. An Enduring Power of Attorney prevents that outcome by giving a trusted person the legal authority to act on your behalf before that crisis hits.

But the document only works if it is set up correctly. South Australia has specific requirements for witnessing, registration, and revocation — and some critical rules about when an EPA stops working entirely.

What an Enduring Power of Attorney Does

An Enduring Power of Attorney (EPA) is a legal document in which you (the donor) appoint an attorney to make financial and legal decisions on your behalf. The key word is "enduring" — unlike an ordinary power of attorney, which lapses if you lose mental capacity, an EPA specifically continues to operate once you lose the ability to make decisions for yourself. That is precisely the scenario you are preparing for.

An EPA covers financial and legal matters only: managing bank accounts, paying bills, buying and selling property, managing investments, operating a business. It does not cover medical or lifestyle decisions. Those require a separate Advance Care Directive with an appointed Substitute Decision-Maker.

Many South Australians need both documents running alongside each other: the ACD for healthcare decisions, the EPA for financial ones.

Setting Up an EPA in South Australia

To create a valid EPA in South Australia, you must:

1. Complete the official Enduring Power of Attorney form (available from the Office of the Public Advocate).
2. Sign the document before an authorised witness — a legal practitioner or a Justice of the Peace.
3. Ensure the witness confirms in writing that they witnessed your signature, that you appeared to understand the document's effect, and that you signed voluntarily.

The witness is not simply a formality. They are certifying that you have the legal capacity to grant the power of attorney. If there is any question about your mental state at the time of signing — for example, if you have an existing dementia diagnosis — this can be challenged later. In those circumstances, getting a written assessment of capacity from your doctor beforehand provides important protection.

You can appoint one attorney or multiple attorneys. If you appoint multiple attorneys, specify in the document whether they must act jointly (all must agree before any decision is made) or jointly and severally (either can act independently). Each approach has trade-offs: joint authority adds a check but can paralyse decision-making; several authority increases flexibility but also the risk of unilateral actions.

When You Need to Register with the Lands Titles Office

For most purposes, an EPA does not need to be formally registered anywhere after it is signed. Your attorney can present it to banks, utilities, and government agencies without registration.

The exception is real estate. If your appointed attorney needs to sell, transfer, or mortgage real property on your behalf, the EPA must first be lodged with the Lands Titles Office (LTO). Without LTO registration, a conveyancer cannot act on the EPA and the transaction cannot proceed through PEXA (the electronic conveyancing platform used for all South Australian property transfers).

If your estate includes real property and you want your attorney to be able to manage it, plan for LTO registration from the outset rather than scrambling to do it under pressure.

How to Revoke an EPA While You Still Have Capacity

If you want to cancel an EPA — because your chosen attorney has moved interstate, your relationship has changed, or you simply want to appoint someone else — the revocation process while you still have capacity is straightforward:

1. Complete a formal revocation form (available from the Office of the Public Advocate).
2. Have the revocation witnessed by an authorised person.
3. Provide a copy of the revocation to the person whose appointment you are cancelling.
4. Lodge the revocation with the Lands Titles Office (if the EPA was registered there).
5. Notify all banks, financial institutions, and government agencies that previously received copies of the EPA.

The last two steps are where people fall short. If you revoke the EPA on paper but the bank still has a copy of the old document, your former attorney can continue to access your accounts until the institution is specifically notified. The revocation document itself does not automatically propagate anywhere.

What Happens if You Lose Capacity Before Revoking

If you lose decision-making capacity, you can no longer revoke your EPA yourself. The document cannot be cancelled or altered by any family member who disagrees with the attorney's decisions, no matter how legitimate their concerns.

Revocation after capacity is lost requires an application to either the Supreme Court of South Australia or the South Australian Civil and Administrative Tribunal (SACAT). This is a formal legal proceeding that requires evidence of the attorney's conduct and the donor's best interests. It is expensive, slow, and emotionally draining. It underscores why choosing the right attorney from the outset — someone trustworthy, organised, and willing to act with transparency — is so critical.

When the EPA Ceases to Exist: Death

This is the point that causes the most confusion and the most serious legal breaches. An EPA ceases to have any legal effect at the moment of the donor's death. Full stop.

If an attorney continues to access a bank account, transfer funds, or make financial decisions after the donor has died, they are acting without legal authority. This is a serious breach regardless of whether the attorney believes they are protecting the estate or acting in the family's interests. Banks that release funds based on an EPA after a client's death are also acting improperly, and they can face liability claims from the estate.

The authority to manage the estate passes to the executor named in the will at the point of death. If there is no will, no one has authority to act until an administrator is appointed by the Supreme Court.

If your attorney and executor are different people — which is common — both need to understand exactly where one role ends and the other begins. The EPA covers incapacity; the will and executor cover death. There is no overlap.

What to Do if There Is No EPA and the Person Has Already Lost Capacity

If someone has already lost decision-making capacity and there is no valid EPA in place, the situation requires court or tribunal intervention. The family cannot simply step in and access accounts. Options include:

• Applying to SACAT for a guardianship and administration order (covers both personal and financial decisions)
• Applying to the Supreme Court for a limited order

Both processes take time and cost money. The absence of an EPA is one of the most preventable sources of stress in elder care situations.

Putting It All Together

An EPA sits in the middle of a three-document framework for managing an ageing person's affairs: the ACD handles healthcare decisions during incapacity, the EPA handles financial decisions during incapacity, and the will handles asset distribution after death.

If you are helping a parent or relative prepare for the future, or working through your own estate planning, getting all three documents in place while capacity is clear is significantly cheaper and less stressful than trying to untangle the alternatives later.
