Power of Attorney: What It Is, Why You Need One, and How to Get It Right

Seam Media • March 3, 2026

Planning for a time when you might not be able to make your own decisions isn't something most people want to think about. But having the right documents in place now means the people you trust can step in and act on your behalf if that time ever comes.


A Power of Attorney is one of the most important legal documents you can have and one of the most misunderstood.

What Is a Power of Attorney?

A Power of Attorney is a legal document that allows you to appoint someone you trust to make decisions on your behalf. The person you appoint is called your "attorney" - not in the legal profession sense, but simply the person authorised to act for you.

In Victoria, there are several types of Power of Attorney, and each one serves a different purpose.


The Different Types

General (Non-Enduring) Power of Attorney

This allows your attorney to manage your financial and legal affairs, but only while you have capacity to make your own decisions. It's often used for practical situations - for example, if you're travelling overseas and need someone to handle a property settlement on your behalf.

If you lose mental capacity, a general Power of Attorney automatically ends.

Enduring Power of Attorney (Financial)

This is the one most people need. An enduring Power of Attorney for financial matters continues to operate even if you lose the ability to make decisions for yourself. Your attorney can manage your bank accounts, pay bills, deal with property, and handle other financial matters.

You can choose whether it takes effect immediately or only when you lose capacity.

Enduring Power of Attorney (Medical Treatment)

This appoints someone to make medical treatment decisions on your behalf if you become unable to make them yourself. This includes decisions about surgery, medication, and other treatment options.

Your medical attorney should be someone who understands your values and wishes regarding healthcare.

Supportive Attorney

A newer option in Victoria, a supportive attorney helps you make and give effect to your own decisions rather than making decisions for you. This can be appropriate if you need assistance but still want to maintain control over your own affairs.


Why You Need One

Many people assume their spouse or adult children will automatically be able to manage their affairs if something happens. This isn't the case.

Without a valid Power of Attorney, your family may need to apply to VCAT (Victorian Civil and Administrative Tribunal) to be appointed as your guardian or administrator. This process can be time-consuming, stressful, and expensive - all during a period when your family is already dealing with a difficult situation.

Common scenarios where a Power of Attorney becomes essential:

  • A stroke, accident, or illness leaves you unable to communicate or make decisions
  • Dementia or cognitive decline develops gradually over time
  • You're having a planned surgery and want someone authorised to act just in case
  • You're ageing and want to ensure a smooth transition if your health declines


Choosing the Right Attorney

This is one of the most important decisions you'll make. Your attorney should be someone who:

  • You trust completely with your finances and personal affairs
  • Understands your values and wishes
  • Is willing and able to take on the responsibility
  • Is organised and capable of managing financial matters
  • Will act in your best interests, even under pressure from others

You can appoint more than one attorney and specify whether they must act jointly (together) or severally (independently). You can also appoint different attorneys for financial and medical decisions.


Common Mistakes to Avoid

Waiting too long

You can only make a Power of Attorney while you have mental capacity. If you wait until a diagnosis of dementia or after a serious health event, it may be too late.

Using DIY kits without advice

While it's possible to create a Power of Attorney without a solicitor, mistakes in execution or wording can render the document invalid. The cost of getting it done properly is minimal compared to the cost of getting it wrong.

Not having the conversation

Your attorney needs to know they've been appointed and understand your wishes. A Power of Attorney sitting in a drawer that nobody knows about won't help anyone when it's needed.

Forgetting to update it

Like a will, your Power of Attorney should be reviewed when your circumstances change - particularly if your relationship with your appointed attorney changes, or if they become unable to act.


When Should You Set One Up?

The short answer is now. It doesn't matter whether you're 30 or 80 - accidents and illness don't discriminate by age. Having these documents in place is simply part of responsible planning.

If you already have a Power of Attorney, consider when it was last reviewed. Does it still reflect your wishes? Is your appointed attorney still the right person for the role?


Take the Step Today

Setting up a Power of Attorney is straightforward and gives you peace of mind that the people you trust can look after your affairs if you're ever unable to do so yourself.

When a relationship ends, one of the biggest questions people ask is: "Do we just split everything down the middle?" The short answer is no. Property settlement in Australia doesn't work on a simple 50/50 rule. The outcome depends on your specific circumstances, and two couples with similar assets can end up with very different results. Understanding how the process actually works can help you feel more prepared and less anxious about what comes next.

Finding your dream home is an emotional journey. After weeks of open inspections and searching online listings, it’s easy to get swept up in the excitement when you finally find "the one." However, before you raise your hand at an auction or sign a contract, there is one crucial document you must understand: the Section 32 Vendor’s Statement. At Lardners Solicitors, we often see clients who are eager to sign but haven't fully scrutinised the legal details of the property. Here is why getting legal advice on the Section 32 is vital before you commit.
