In short

A power of attorney lets a trusted person make decisions for you. A general power of attorney only works while you still have capacity and ends the moment you lose it — the opposite of protection. Only an enduring power of attorney (for finances) plus an enduring guardianship or advance care directive (for health) protect you if you lose capacity, and both must be made while you're still well.

Almost everyone understands they should have a will. Far fewer understand that they also need a power of attorney — and that's a problem, because the two documents do completely different jobs. A will deals with your assets after you die. A power of attorney protects you while you're alive but unable to make your own decisions — after a stroke, a serious accident, or the onset of dementia. Put bluntly, a power of attorney is arguably *more* likely to be needed than a will, yet it's the one most people don't have. And there's a trap in the detail that catches even those who think they're covered. Here's what the different powers of attorney are, and which ones you actually need. This article is general information only, not personal or legal advice.

What are the types, explained?

"Power of attorney" is really an umbrella term for a few different documents. A general power of attorney appoints someone to make financial and legal decisions on your behalf — but only while you still have the capacity to make decisions yourself. People use one when they're going overseas for a while, or simply want help managing their affairs. The crucial thing to understand is that a general power of attorney ends the moment you lose capacity, which means it is *not* the document that protects you against incapacity (ASIC MoneySmart, https://moneysmart.gov.au/plan-for-your-retirement/wills-and-powers-of-attorney). This is exactly the trap: plenty of people sign a general power of attorney and assume they're covered for the future. They're not.

An enduring power of attorney is the one that matters most. It also covers financial and legal decisions, but — as the name says — it endures: it continues to operate even if you lose the ability to make decisions yourself (ASIC MoneySmart, https://moneysmart.gov.au/glossary/enduring-power-of-attorney). This is the document that lets a trusted person keep your finances running if illness or age ever takes away your ability to do it yourself.

And then there's the health and lifestyle side, covered by a document variously called an enduring guardianship, a medical power of attorney, or an advance care directive, depending on where you live. This lets a trusted person make medical and lifestyle decisions for you if you can't make them yourself, and it sits alongside the broader idea of advance care planning (Australian Government, https://www.health.gov.au/topics/palliative-care/planning-your-palliative-care/advance-care-planning). Our separate article on enduring guardianship goes into it.

What is the key point — do only the "enduring" versions protect you?

If you take one thing from this article, take this: a general power of attorney and an enduring power of attorney are not interchangeable. Only the enduring documents — financial *and* health — protect you if you lose capacity. So it's genuinely worth checking which one you actually have, because a lot of people are holding a general power of attorney in the belief that it will cover them in old age, when it will do the opposite.

Why does everyone need them?

Here's what happens if you lose capacity without an enduring power of attorney in place: no one can automatically step in — not even your spouse. It surprises people, but marriage doesn't give an automatic right to manage a partner's finances or make their care decisions (ASIC MoneySmart, https://moneysmart.gov.au/glossary/power-of-attorney-poa). Instead, your family has to apply to a state tribunal — the NSW Civil and Administrative Tribunal (NCAT) in New South Wales, the Victorian Civil and Administrative Tribunal (VCAT) in Victoria, and their equivalents elsewhere — to be appointed to act for you, often under a financial management or guardianship order. That process is slow, costs money, and adds stress at what is already one of the hardest times a family faces. A single document, signed while you were well, avoids all of it. The same goes for dealing with Centrelink or Medicare on someone's behalf, which has its own separate authorisation process (Services Australia, https://www.servicesaustralia.gov.au/someone-to-act-for-you-with-medicare-centrelink-aged-care-or-child-support).

Can you only make them while you're well?

And that's the catch that makes this urgent: you can only make a power of attorney while you still have capacity. Once capacity is gone — once dementia has advanced, say — it is too late, and the tribunal route is the only option left. So, exactly like a will, a power of attorney is a document you put in place in advance, while you're healthy and not expecting to need it. The best time to do it is well before you think you have to.

How do you choose your attorney?

The person you appoint — your attorney — should be someone trusted, capable and willing to take it on. You can appoint more than one person (to act together, or separately), and it's wise to name a backup in case your first choice can't act when the time comes. Bear in mind that an attorney takes on real legal duties: to act in your best interests, to keep your money entirely separate from their own, and to keep records. Our article on an attorney's duties covers what the role involves, and our piece on DIY will kits versus a solicitor explains why these documents are usually best prepared professionally.

What do the worked examples show?

These show the trap and the fallback in action. They are illustrative only, not personal or legal advice.

Consider Frank, 72, who signed a general power of attorney a decade ago so his daughter could manage a property sale while he travelled overseas, and has assumed ever since that it protects him for old age. On these facts that assumption is the costly mistake: a general power of attorney ends the moment Frank loses capacity, so if he were to develop dementia the document would simply stop working rather than let his daughter step in (ASIC MoneySmart, https://moneysmart.gov.au/plan-for-your-retirement/wills-and-powers-of-attorney). On these facts it is generally rational for someone in Frank's position to check which document he actually holds and, while he is still well, put in place an enduring power of attorney for his finances and an enduring guardianship or advance care directive for his health.

Now consider Susan and David, a married couple in their late 60s, when David has a sudden stroke and can no longer manage money or make decisions, with no enduring power of attorney in place. On these facts Susan discovers what surprises most people: being David's wife does not automatically let her operate his accounts or make his care decisions, and she must apply to the state tribunal — NCAT if they live in New South Wales — to be formally appointed, a process that takes time and money at an already distressing moment (ASIC MoneySmart, https://moneysmart.gov.au/glossary/power-of-attorney-poa). On these facts it is generally rational for other couples reading Susan and David's story to each make an enduring power of attorney and a health directive now, while both still have capacity, so that neither is ever left going through a tribunal to help the other.

What should you do?

The names, forms and witnessing rules for these documents vary by state and territory, so this is an area where a solicitor is well worth using — and powers of attorney are very commonly prepared at the same time as your will, which makes it easy to sort the whole lot in one go. So the plan is simple: while you're well, put in place an enduring power of attorney for your finances and an enduring guardianship or advance care directive for your health, alongside your will; choose trusted attorneys and a backup; store the documents somewhere safe and findable and tell the people who need to know; and review them after any big life change. It's not a cheerful task, but it's one of the most protective things you can do — for yourself, and for the people who'd otherwise be left navigating a tribunal on your behalf.

Frequently asked questions

What is the difference between a general and an enduring power of attorney?

A general power of attorney appoints someone to make financial and legal decisions on your behalf, but only while you still have capacity — it ends the moment you lose capacity. An enduring power of attorney continues to operate even if you lose the ability to make decisions yourself, which is why it's the one that actually protects you against incapacity.

Does my spouse automatically get to manage my affairs if I lose capacity?

No. Marriage doesn't give an automatic right to manage a partner's finances or make their care decisions. Without an enduring power of attorney, your family would have to apply to a state tribunal to be formally appointed, a process that's slow, costly, and adds stress at an already difficult time.

What documents do I need to be fully protected?

An enduring power of attorney covers financial and legal decisions if you lose capacity. Separately, an enduring guardianship, medical power of attorney, or advance care directive (the name varies by state) covers health and lifestyle decisions. Both are needed alongside a will, which only takes effect after death.

When should I make a power of attorney?

As early as possible, while you're still healthy. You can only make a power of attorney while you have capacity — once it's gone, for example after advanced dementia, it's too late, and a tribunal application becomes the only option for your family.
