How to Ensure Your Power of Attorney Is Legally Binding in NSW

By CM Lawyers – Power of Attorney Specialists in Marrickville, NSW

When you create a Power of Attorney (POA), you’re giving someone the authority to make important legal and financial decisions on your behalf. But here’s the reality: not all Powers of Attorney are created equal.

If your POA is missing key elements, isn’t execuwillted properly, or doesn’t meet NSW’s strict legal requirements, it could be invalid—leaving your attorney powerless when you need them most.

At CM Lawyers in Marrickville, we specialise in preparing Powers of Attorney that are not only tailored to your needs but airtight in their legality. In this guide, we’ll explain exactly how to ensure your Power of Attorney in Marrickville is legally binding in NSW, based on our years of experience helping clients across Sydney and the Inner West.

Why Validity Matters

A Power of Attorney is a legal tool, but it only works if:

It’s correctly drafted.

It’s signed and witnessed by the right person.

It meets all legislative requirements under the Powers of Attorney Act 2003 (NSW).

We’ve seen clients come to us with DIY templates or outdated documents that weren’t worth the paper they were printed on—often discovered when it was too late. That’s why getting it right from the start is critical.

Step 1: Choose the Right Type of Power of Attorney

In NSW, there are two main types:

General Power of Attorney – Used for short-term or specific purposes, such as when you’re overseas and need someone to manage property transactions. It ends if you lose mental capacity.
Enduring Power of Attorney – Continues to operate even if you lose capacity, making it essential for long-term planning.

At CM Lawyers, we help you determine which type best suits your circumstances. Choosing the wrong one can limit your attorney’s authority or make the document useless in the future.

Step 2: Appoint the Right Attorney

You can appoint one or more attorneys, but they must be:

Over 18 years old.

Someone you trust completely.

Capable of managing legal and financial responsibilities.

We often advise clients to consider the practicalities—is your chosen attorney local and able to act quickly if needed? Can they work well with co-attorneys if appointed jointly?

Step 3: Draft the Document Correctly

Your Power of Attorney must clearly outline:

The scope of powers given.

Any limitations or conditions.

How attorneys make decisions (jointly or severally).

Our solicitors ensure every detail is correct and compliant with NSW law, so there’s no ambiguity. A poorly drafted POA can lead to disputes, delays, or legal challenges.

Step 4: Meet the Witnessing Requirements

In NSW, witnessing is more than just signing a piece of paper.

General POA – Can be witnessed by any adult not named in the document.

Enduring POA – Must be witnessed by a prescribed witness, such as a solicitor or barrister.

At CM Lawyers, we act as prescribed witnesses and certify that you understand the document and its implications before you sign. This step is vital for your POA to be legally binding.

Step 5: Register if Property Is Involved

If your POA will be used for real estate transactions in NSW, it must be registered with NSW Land Registry Services (LRS). Without registration, your attorney cannot buy, sell, or transfer property on your behalf.

Our team handles the entire process—from preparing the forms to lodging the POA—ensuring it’s registered quickly and without errors.

Step 6: Keep It Accessible and Up to Date

Once your POA is complete:

Store the original safely (we can store it securely for you).

Provide certified copies to your attorney and relevant institutions.

Review it regularly, especially if your circumstances change.

We offer ongoing support, so if you need to update or revoke your POA, it’s done correctly and without legal gaps.

Common Mistakes That Make a POA Invalid

From our experience in Marrickville, the most common issues include:

Using outdated or interstate templates not compliant with NSW law.

Failing to use a prescribed witness for an Enduring POA.

Not registering when property transactions are required.

Ambiguous powers or missing details.

Each of these mistakes can be avoided with proper legal advice.

Client Story: Avoiding a Costly Delay

A client recently came to us after attempting to use an online POA form for a property sale. The form was invalid under NSW law and hadn’t been registered. The property settlement was at risk of falling through.

We urgently prepared a compliant Enduring POA, witnessed it, and lodged it with LRS. The sale proceeded on time—saving the client thousands in potential penalties.
