Advance Personal Plan Mistakes to Avoid in the NT

Witnessing Errors

The most common reason an APP is rejected or challenged is a witnessing failure. NT law requires the document to be signed in the physical presence of an authorised witness. The list of authorised witnesses includes justices of the peace, legal practitioners, medical practitioners, nurses, pharmacists, police officers, and social workers.

The witness must physically sign the document, print their full name, address, and professional credentials, and certify that the maker appeared to understand the document and acted voluntarily.

Common failures:

• The witness does not include their professional credentials alongside their signature
• Someone who is not an authorised witness signs (a friend, a family member, a neighbour)
• The maker and witness sign at different times rather than in each other's physical presence
• The witness is also an appointed decision-maker in the plan — this creates a conflict of interest that can invalidate the appointment

Electronic Signatures

The Northern Territory requires wet-ink signatures for Advance Personal Plans. Electronic signatures — DocuSign, scanned signatures, or digital signing platforms — are not accepted. This catches people who download the PDF form and try to complete the process digitally.

The form must be printed on A4 paper (single-sided for scanning purposes), signed physically, and witnessed in person.

The Combined Document Problem

This is not a legal invalidity issue — a combined APP covering both financial and healthcare matters is perfectly legal. But it creates severe practical problems.

When your financial decision-maker presents the combined APP to a bank, the bank's compliance team must review the entire document to verify the decision-maker's authority. That means bank staff reading through your intimate medical preferences, treatment refusals, and lifestyle wishes. Banks frequently delay or reject transactions because their risk teams are uncertain about the scope of a combined document.

The fix is to create two separate APPs: one for financial and property matters, one for healthcare and lifestyle. Both are valid under the Advance Personal Planning Act 2013. The financial APP goes to the bank; the healthcare APP goes to the hospital.

Vague Treatment Instructions

"No heroic measures" and "I want to die with dignity" are the two most common phrases in advance directives across Australia, and neither gives clinicians actionable guidance. In a crisis at Royal Darwin Hospital, the treating team needs to know specifically which treatments you refuse and under which clinical circumstances.

An Advance Consent Decision must be specific to be enforceable. "I refuse mechanical ventilation if I have a progressive neurological condition with no realistic prospect of meaningful recovery" is enforceable. "No extreme measures" is not — it does not define what counts as extreme, and the treating team is left guessing.

Forgetting Registration

Creating and signing the APP is only part of the process. If no one can find the document during an emergency, it is functionally useless.

Public Guardian and Trustee registration is free and creates a central, verifiable record. Without registration, clinicians must rely on paper copies that may or may not be available.

Land Titles Office registration is mandatory if the APP grants authority over real property. Forgetting this step means your decision-maker cannot legally sell or manage property on your behalf, regardless of what the APP says.

My Health Record upload makes the plan accessible to hospital staff during emergencies via the national health record system.

Not Updating After Life Changes

An APP created when you were healthy and married may not reflect your situation after a divorce, a new relationship, a diagnosis, or a family estrangement. Key triggers that should prompt a review:

• Divorce or separation from a de facto partner (your ex may still be your appointed decision-maker unless you revoke the appointment)
• New diagnosis of a progressive condition
• Your appointed decision-maker moves interstate or dies
• Significant change in your financial situation (new property, business)
• Relationship breakdown with an appointed decision-maker

An outdated APP with the wrong decision-maker is worse than no APP at all — it gives legal authority to someone who may no longer understand or respect your wishes.

Printing Errors

The APP and Supreme Court probate processes have separate formatting requirements. For the APP, use the statutory form and print it single-sided. For probate filings, keep each form and supporting document as a separate PDF. Common printing errors include:

• Printing the form double-sided when single-sided is required
• Altering the statutory APP or court template (deleting standard bracketed text, changing font sizes)
• Merging multiple probate forms into a single PDF rather than keeping them as separate documents

These seem minor but can cause real delays or rejection.

Getting It Right

Our Northern Territory Advance Directive & Living Will Kit includes a signing and witnessing checklist that walks through every requirement, the split-document strategy with separate financial and healthcare templates, and a clinical translation worksheet for converting your preferences into specific, enforceable Advance Consent Decisions.
