To understand why the answer to “can a power of attorney change a Will in Australia” is no, you need to first understand what a power of attorney is.
We will explain the factors to the answer of the question, ‘can a power of attorney change a Will in Australia?.’ Additionally, we will also shed light on some of the functions and purpose of a power of attorney.
Can a Power of Attorney Change a Will in Australia?
A power of attorney is a legal document that authorises a trustee, a person, or an organisation to act on behalf of a party to manage their assets and make legal and financial decisions for them. It can appoint one person or more than one person for these purposes. Someone has to look after your financial affairs in such circumstances.
These documents are useful if you lose mental capacity to make these decisions for yourself. For example, such situations may arise if you suffer from some illness, injury or disability. The power of attorney can do the following:
- operating bank accounts
- signing legally binding documents
- paying bills
- managing investments
- collecting rent
- buying and selling real estate (they must comply with the registration with the NSW Land Registry Services)
Given the wide range of powers that a power of attorney has, can a power of attorney change a Will in Australia? As we have mentioned, they can’t. This is because a Will is separate to a power of attorney.
A Will is a legal document that outlines the wishes of the testator. Moreover, it states the manner of distribution of their assets after their death, such as bank account, or real estate and other estates.

Types of Power of Attorney NSW
In NSW, there are two main types of Power of Attorney that individuals can use to delegate authority to another person for various purposes. These are:
- General Power of Attorney: This grants broad powers to the attorney to manage financial and legal affairs on behalf of the principal. It’s often for temporary or specific purposes, like handling financial transactions while you are abroad.
- Enduring Power of Attorney: This type of power of attorney continues if the principal becomes mentally incapacitated. It can cover both financial and personal matters. But it must specifically state that it is “enduring” to be effective in such circumstances.
How to Make a Power of Attorney in NSW?
Creating a Power of Attorney (POA) in NSW involves several steps. Thus, it is highly recommended to consult with a qualified legal professional. This will ensure that the document is correctly drafted and complies with NSW laws and regulations.
Here’s a general outline of the process:
- Choose the Type of POA: Determine the type of power of attorney document that suits your needs. It could be a General Power of Attorney or Enduring Power of Attorney
- Select an Attorney: Choose the person or persons you want to appoint as your attorney(s). Ensure the appointed person are willing and capable of carrying out the responsibilities you intend to assign to them. This could be a close friend, a family member, NSW Trustee & Guardian or a public trustee organisation or a solicitor.
- Consult a Solicitor: It’s recommended to consult with a solicitor or lawyer experienced in NSW’s POA laws. They can provide legal advice, help you understand the requirements and ensure the document is correctly drafted.
- Draft the POA Document: Work with your attorney or solicitor to draft the POA document. The document should clearly state your intention, the powers granted to the attorney, any limitations and whether it’s enduring or not.
Additional Steps
- Include Witness Signatures: In NSW, a witness must sign a POA. Usually it requires the signature of the principal (you), the attorney(s) and one or more witnesses. The witnesses must be over 18 years old and not be beneficiaries or attorneys themselves.
- Certification: Depending on the type of POA, you may need a certification of legal capacity from a medical practitioner or other qualified professionals, especially for enduring powers of attorney.
- Registration: Certain types of POAs, like enduring powers of attorney, may need to be registered with the NSW Land Registry Services (LRS) office. Your solicitor can guide you through this process.
- Keep Copies: Keep copies of the signed and witnessed POA document in a safe place, and provide copies to your attorney(s) as needed.
- Review Periodically: It’s good practice to review your POA periodically and update if necessary, especially if there have been changes in your circumstances or the people you’ve appointed as attorneys.
Remember, creating a POA is a legal matter and errors or omissions in the document can have serious consequences. Consult a solicitor for these purposes.
