Creating an Enduring Power of Attorney in South Australia - Complete Guide

By James Stevens, Director and Solicitor, Go To Court Lawyers. Last reviewed 10 April 2026.

An enduring power of attorney in South Australia is a crucial legal document that allows someone you trust to make financial or personal decisions on your behalf if you lose mental capacity. Unlike an ordinary power of attorney, an enduring power specifically survives your loss of capacity - continuing to operate when you can no longer make decisions yourself. You must create this document while you still have full mental capacity, and it must comply with strict South Australian legal requirements to be valid.

Do You Need a Lawyer?

While South Australia allows you to complete enduring power of attorney forms yourself, getting legal help is strongly recommended. A single mistake in the witnessing requirements, form completion, or understanding of attorney powers can render your document invalid when you need it most. A lawyer ensures your enduring power of attorney properly reflects your wishes, meets all legal requirements, and protects you from potential abuse.

Without proper legal guidance, you risk creating a document that won't work when your family needs it, or worse, one that gives an attorney more power than you intended. The consequences of an invalid or poorly drafted enduring power of attorney can include lengthy court proceedings, family disputes, and decisions being made by strangers appointed by the South Australian Civil and Administrative Tribunal (SACAT).

What Happens Next - The Process

1. Choose your attorney carefully: Select someone you trust completely to act in your best interests. This person will have significant power over your finances or personal decisions.
2. Decide on the type: Choose between an enduring power of attorney for financial decisions, personal/health decisions, or both (using separate documents).
3. Complete the official South Australian form: Use only the prescribed forms available from the South Australian Attorney-General's Department or Courts Administration Authority.
4. Include specific instructions: Write clear directions about what your attorney can and cannot do, any restrictions on their powers, and your preferences for care or financial management.
5. Arrange proper witnessing: Have the document witnessed by an eligible person who meets South Australia's strict witnessing requirements.
6. Store the original safely: Keep the original document secure but accessible to your attorney when needed. Consider lodging a copy with your lawyer.
7. Inform relevant parties: Tell your attorney, family members, doctor, and financial institutions that you have created an enduring power of attorney.
8. Review regularly: Update your enduring power of attorney if your circumstances change or if you want to change your attorney.

The Law in South Australia

Enduring powers of attorney in South Australia are governed by the Powers of Attorney and Agency Act 1984 (SA). This Act sets out specific requirements that must be followed for your document to be legally valid and enforceable.

South Australia recognises two distinct types of enduring powers of attorney:

Enduring Power of Attorney (Financial): Covers property and financial matters including banking, investments, real estate transactions, tax affairs, and business decisions. Your attorney can access bank accounts, sell property, make investments, and handle all financial affairs as specified in the document.

Enduring Power of Attorney (Personal/Health): Covers personal care and health decisions including medical treatment, accommodation arrangements, lifestyle choices, and social activities. This does not include financial decisions and operates under different legal constraints.

The witnessing requirements under South Australian law are strict. Your enduring power of attorney must be witnessed by either a justice of the peace, commissioner for taking affidavits, notary public, or legal practitioner. Family members, beneficiaries under your will, or anyone who might benefit from the enduring power of attorney cannot act as witnesses.

The Act also establishes clear obligations for attorneys, including acting in your best interests, avoiding conflicts of interest, keeping accurate records, and not using their position for personal benefit unless specifically authorised.

Mistakes to Avoid

Using outdated or incorrect forms: Many people download old forms from unofficial websites or use interstate forms. South Australia has specific prescribed forms that must be used. Using the wrong form renders your enduring power of attorney invalid, potentially leaving your affairs in limbo when you need protection most.

Improper witnessing: The most common error we see is having the document witnessed by ineligible people - often family members or friends who cannot legally witness an enduring power of attorney. This single mistake invalidates the entire document, regardless of how well it was otherwise prepared.

Choosing the wrong attorney: Appointing someone based on family relationships rather than capability and trustworthiness causes significant problems. We've seen cases where well-meaning but financially inexperienced attorneys make poor decisions, or worse, where attorneys abuse their position for personal gain.

Failing to provide clear instructions: Vague or contradictory instructions in your enduring power of attorney create confusion and disputes. Without specific guidance about your preferences, attorneys may make decisions you wouldn't approve of, or family members may challenge their choices.

Not understanding the scope of powers: Many people don't realise how broad the powers they're granting can be. An enduring power of attorney for financial matters can allow your attorney to give away your property, change your will's beneficiaries (in some circumstances), or make major financial decisions without consulting anyone.

Likely Outcomes and Costs

With proper legal assistance, you can expect a comprehensive enduring power of attorney that protects your interests and clearly expresses your wishes. A lawyer will ensure all South Australian legal requirements are met, reducing the risk of future challenges or invalidity. Professional drafting typically costs between $400-$800 depending on complexity, but this investment protects assets potentially worth hundreds of thousands of dollars.

Going alone risks creating an invalid document that fails when you need it most. Court applications to resolve invalid enduring powers of attorney typically cost $3,000-$10,000 and take 6-12 months to resolve. During this time, your affairs may be frozen or managed by court-appointed administrators who don't know your wishes.

A well-drafted enduring power of attorney provides immediate peace of mind and can save your family thousands of dollars in legal fees and court costs. It also ensures your preferences are followed rather than having decisions made by strangers according to generic legal principles.

If attorney abuse occurs, recovery of misused funds through legal action typically costs $10,000-$50,000 depending on the amount involved and complexity of the case. Prevention through proper initial drafting and safeguards is always more cost-effective than attempting to recover losses after the fact.
