Powers of Attorney Explained

A Will deals with what happens after you die. But what if you become unable to manage your affairs while still alive? That's where Powers of Attorney come in.

Last updated: January 2025 | 15 min read

1. What is a Power of Attorney?

A Power of Attorney (POA) is a legal document that authorises another person (your "attorney") to act on your behalf. Despite the name, your attorney doesn't need to be a lawyer—they can be any trusted adult.

Critical Distinction

A Will only takes effect after you die. A Power of Attorney operates while you're alive. Both are essential parts of a complete estate plan.

Why You Need a Power of Attorney

Consider what would happen if you:

  • Were in a serious accident and in a coma
  • Developed dementia or Alzheimer's disease
  • Had a stroke that affected your cognitive abilities
  • Were travelling overseas and unable to manage affairs at home

Without a valid POA, your family would need to apply to a tribunal or court for guardianship/administration orders—an expensive, time-consuming, and stressful process during an already difficult time.

Key Point

You can only create a POA while you have mental capacity. Once you lose capacity, it's too late. This is why everyone should have POAs in place before they're needed.

2. Types of Powers of Attorney

There are several types of POA, each serving different purposes:

📋

General Power of Attorney

Authorises your attorney to handle financial and legal matters on your behalf.

Limitation: Automatically ends if you lose mental capacity.

🛡️

Enduring Power of Attorney (Financial)

Continues to operate even after you lose mental capacity—when you need it most.

Essential: This is the type most people need for estate planning.

🏥

Medical/Healthcare Power of Attorney

Authorises your attorney to make medical and healthcare decisions if you can't.

Note: Called different names in different states (see state differences below).

📝

Advance Care Directive

Not technically a POA—records your own wishes about future medical treatment rather than appointing someone to decide.

Complementary: Often used alongside a Medical POA.

3. Financial Powers of Attorney

A financial POA (specifically an Enduring Power of Attorney for financial matters) allows your attorney to manage your money and property.

What Your Financial Attorney Can Do

  • Pay your bills and debts
  • Operate your bank accounts
  • Manage investments
  • Lodge tax returns
  • Buy and sell property
  • Run your business
  • Deal with government agencies
  • Sign contracts on your behalf

What They Cannot Do

  • Make or change your Will
  • Vote on your behalf
  • Make medical decisions (unless also appointed as medical attorney)
  • Act outside the scope of powers you've granted

General vs Limited Powers

You can grant:

  • General powers: Your attorney can do almost anything you could do yourself (most common)
  • Limited powers: Restrict to specific matters (e.g., only managing a particular property while you're overseas)

When Does It Start?

You can specify when the POA begins:

  • Immediately: Your attorney can act straight away (useful if you want help managing affairs)
  • Upon incapacity: Only activates when you lose capacity (common for younger people)
  • Upon a specific event: e.g., when you travel overseas

4. Medical Powers of Attorney

A medical or healthcare POA allows your attorney to make health and medical decisions when you're unable to make them yourself.

Types of Decisions

Consenting to Medical Treatment

Surgery, medication, procedures, experimental treatments

Refusing Treatment

Including life-sustaining treatment in end-of-life situations

Living Arrangements

Decisions about where you'll live (home, aged care facility)

Personal Care

Day-to-day care, lifestyle choices, social activities

State Terminology

Each state calls medical POAs something different:

State Term Used
NSWAppointment of Enduring Guardian
VictoriaAppointment of Medical Treatment Decision Maker
QueenslandEnduring Power of Attorney (for personal/health matters)
WAEnduring Power of Guardianship
SAAdvance Care Directive (appoints substitute decision-maker)
TasmaniaEnduring Guardian
ACTEnduring Power of Attorney (for health care)
NTAdvance Personal Plan (appoints decision maker)

Important Note

Medical POA documents are state-specific. If you move interstate, you should create new documents that comply with your new state's legislation. Unlike Wills, medical POAs don't always transfer cleanly between states.

5. Advance Care Directives

An Advance Care Directive (ACD)—also called a Living Will or Advance Health Directive—is a document where you record your own wishes about future medical treatment.

ACD vs Medical POA: What's the Difference?

Advance Care Directive

  • • Records YOUR specific wishes
  • • States what treatments you do/don't want
  • • Directly instructs healthcare providers
  • • May not cover every possible scenario

Medical Power of Attorney

  • • Appoints someone to decide FOR you
  • • They use their judgment based on your values
  • • Can respond to unforeseen situations
  • • More flexible but relies on their choices

Best practice: Have BOTH. Your ACD guides your medical attorney about your values and specific wishes, while they can handle situations your ACD doesn't cover.

What to Include in an ACD

  • Life-sustaining treatment: Your wishes about CPR, mechanical ventilation, feeding tubes
  • Pain management: Preferences about pain relief even if it may hasten death
  • Organ donation: Whether you wish to donate organs
  • Values statement: What matters most to you about quality of life
  • Religious/cultural considerations: Any faith-based treatment preferences

Conversation is Key

The most important thing you can do is discuss your wishes with your family and medical attorney. A document is valuable, but understanding gained through conversation helps your loved ones make decisions that truly reflect your values.

6. Choosing Your Attorney

Choosing an attorney is one of the most significant decisions you'll make. This person will have considerable power over your life and assets.

Essential Qualities

Trustworthy

They'll have access to your finances and personal information

Responsible

Able to make careful, considered decisions

Available

Willing and able to take on the role when needed

Understands Your Values

Especially important for medical decisions

Geographically Accessible

Can physically attend to matters if required

Good Communicator

Can liaise with family, doctors, and institutions

Common Choices

  • Spouse/Partner: Most common choice. They know you well and have a vested interest.
  • Adult Child: Often appropriate, especially if your spouse has passed or also lacks capacity.
  • Sibling or Other Family: A trusted relative who understands your values.
  • Close Friend: Sometimes more appropriate than family in certain circumstances.
  • Professional: Solicitors or trustee companies can act (fees apply).

Multiple Attorneys

You can appoint more than one attorney:

  • Jointly: They must all agree on every decision (can cause delays)
  • Severally: Any one of them can act independently
  • Jointly and severally: They can act together or independently
  • Substitute attorney: Steps in if the primary attorney can't act

Warning

Never appoint someone solely because you feel obligated. A poorly chosen attorney can cause significant financial harm or make medical decisions against your wishes. Choose based on capability and trustworthiness, not obligation.

7. State-by-State Differences

Unlike Wills, Powers of Attorney are highly state-specific. Each state has different legislation, forms, and requirements.

  • Note: Must use prescribed forms

Moving Interstate?

If you move to a different state, you should create new POA documents that comply with your new state's laws. While some recognition exists between states, it's not guaranteed, especially for medical POAs.

8. Revoking & Updating Your POA

You can change or revoke your Powers of Attorney at any time while you have mental capacity.

How to Revoke

  1. Create a written revocation: State clearly that you revoke the specific POA, including its date
  2. Notify your attorney(s): Inform them in writing that their appointment is revoked
  3. Notify institutions: Tell banks, land registries, and any organisations that have been using the POA
  4. Destroy old documents: Collect and destroy all copies of the revoked POA

Automatic Revocation

A POA may be automatically revoked by:

  • Creating a new POA that revokes previous ones
  • The attorney dying, losing capacity, or becoming bankrupt (for financial POAs)
  • Marriage or divorce (in some states and circumstances)
  • Your own death (POAs don't continue after death—your Will takes over)

When to Update

Review your POAs when:

  • You marry, separate, or divorce
  • Your attorney dies or becomes unsuitable
  • Your relationship with your attorney changes
  • You move to a different state
  • Your health circumstances change significantly
  • Every 5 years as a general review
