Best Power of Attorney Solution for a Parent Losing Capacity in South Australia
The Direct Answer
If your parent still has legal capacity — they can understand what a power of attorney is, who they are appointing, and what powers they are granting — the best solution is to execute both an Enduring Power of Attorney (Form P2) and an Advance Care Directive on the same day, using a structured kit that covers the dual-document completion process for South Australia. The South Australia Power of Attorney Kit is built for exactly this scenario: the crisis window where a parent's cognitive decline is accelerating and you need both financial and healthcare authority established before the legal threshold is crossed.
If your parent has already lost capacity, the forms become useless. Your only path is a SACAT administration and/or guardianship application — a four-to-six-week process that costs substantially more and may result in the Public Trustee being appointed instead of you.
The window between "declining" and "legally incapable" is where everything happens. Here is how to use it.
Why South Australia Makes This Harder
South Australia splits decision-making authority across two completely separate legal instruments under two different Acts of Parliament:
- Financial authority (banking, property, investments, tax) requires an Enduring Power of Attorney under the Powers of Attorney and Agency Act 1984
- Healthcare and lifestyle authority (medical treatment, residential placement, personal decisions) requires an Advance Care Directive under the Advance Care Directives Act 2013
Complete one without the other and you have legal authority over half the decisions your parent needs you to make — and no authority over the rest. The hospital will recognise your ACD-based authority to consent to treatment, but the bank will freeze your parent's accounts because you have no EPA. Or you have the EPA for financial transactions, but the aged care facility will not accept your instructions about your parent's daily care because you have no ACD appointing you as Substitute Decision-Maker.
Most other Australian states consolidated these instruments years ago. South Australia has not. That means two sets of forms, two signing protocols, two witnessing requirements, and two sets of failure points — all of which must be navigated while your parent's capacity is still legally intact.
The Capacity Clock
Capacity is not binary — it does not switch off overnight. Your parent may have good days and bad days, clear mornings and confused afternoons. But the legal standard for executing an EPA in South Australia is straightforward: the donor must understand the nature of the power being granted, the scope of authority being given to the attorney, and the consequences if that power is misused.
A GP or specialist who has been treating your parent can provide a medical opinion on capacity. If that opinion is "capacity is present but declining," you have your window. If it is "capacity is no longer present for the purposes of executing a legal instrument," the window has closed.
What makes this urgent is that the window often closes faster than families expect. A stroke, a fall requiring hospitalisation, a sudden cognitive episode — any of these can move the medical assessment from "declining" to "lost" within days.

What to Do Right Now (Same-Day Execution Plan)
Step 1: Confirm capacity with your parent's GP
Call the GP's office and request a capacity assessment or a letter confirming your parent's ability to understand and execute legal documents. This letter is not legally required for the EPA or ACD to be valid, but it creates an evidentiary record that protects the documents against future challenge by other family members or institutions.
Step 2: Execute Form P2 (EPA) and ACD together
Both documents should be completed in the same sitting where possible, while your parent's capacity is confirmed and a witness is available. The critical execution points:
- Form P2: Your parent (the donor) signs before an authorised witness (a Justice of the Peace, solicitor, or proclaimed police officer). You (and any other nominated attorney) must sign the Schedule 2 acceptance — if this section is not completed, the EPA is legally inoperative.
- ACD: If your parent appoints you as Substitute Decision-Maker, you must sign the SDM acceptance section before your parent's signature is witnessed. Reverse this order and the ACD is void.
The South Australia Power of Attorney Kit walks through both signing protocols with conflict-of-interest witness screening and a checklist that prevents the sequence errors that void these instruments.
Step 3: Take the EPA to the bank before you need it
Do not wait until your parent is in hospital to present the EPA to their bank. Visit the branch with the original EPA, your parent's identification, your own identification, and a copy of the GP's capacity letter. Ask the branch manager to register the EPA on the account and note the attorney's authority in the system.
Banks routinely reject valid EPAs when attorneys arrive during a crisis without prior registration. A pre-crisis visit — while your parent may even be able to accompany you — eliminates the most common institutional rejection point.
Step 4: Register with Land Services SA if property is involved
If your parent owns real property in South Australia, the EPA must be deposited with Land Services SA under Section 156(3) of the Real Property Act 1886 before you can transact on their behalf. The lodgement fee is $204.00 per donor (2026/2027 financial year). Do this before the property needs to be sold to fund aged care — the registration process takes time, and a last-minute lodgement during an urgent sale creates unnecessary risk.
Who This Is For
- Adult children whose parent has been formally diagnosed with early-stage dementia, mild cognitive impairment, or another progressive condition
- Families where a parent has had a recent health event (stroke, fall, hospitalisation) that has accelerated cognitive decline
- Anyone whose parent is entering residential aged care and needs both financial and healthcare decision-making authority established before the transition
- Families in regional South Australia who cannot easily access a metropolitan solicitor for same-day execution
Who This Is NOT For
- Families where the parent has already been assessed as lacking legal capacity — your path is a SACAT administration and/or guardianship application, not an EPA
- Situations involving active family disputes over who should be appointed attorney — a solicitor can provide independent capacity verification and reduce the risk of future challenge
- Parents with complex business interests, multiple trusts, or cross-border assets where the conditions and limitations of the EPA require professional drafting
The Cost of Waiting
The arithmetic is simple and the numbers are specific to South Australia:
- Solicitor drafting: $165–$1,430+ for EPA and ACD preparation. Appointment wait: one to three weeks in Adelaide, longer in regional areas.
- SACAT application (if capacity is lost): four to six weeks processing time with perfect medical evidence. During this period, bank accounts are frozen, nursing home fees accumulate out of pocket, and mortgage payments may lapse.
- Public Trustee appointment (if SACAT does not appoint family): statutory commission of up to 4.4% on the first $200,000 of assets, plus ongoing administration fees while the order remains in place.
- Self-directed kit: $24, same-day completion, no appointment wait. Covers both EPA and ACD execution, bank acceptance strategy, and SACAT avoidance planning.
Every week of delay narrows the window. The optimal time to execute these documents is not when the crisis hits — it is before the crisis makes execution impossible.
Frequently Asked Questions
Can my parent still sign a power of attorney if they have dementia?
It depends on the stage. Early-stage dementia does not automatically void legal capacity. The legal test is whether your parent understands the nature of the document, who they are appointing, and the consequences. A GP's assessment of capacity at the time of signing creates the evidentiary record. If the dementia has progressed to the point where understanding is absent, the forms cannot be legally executed.
What if my parent loses capacity between signing the EPA and registering it with the bank?
The EPA is valid from the moment it is properly signed and witnessed — registration with the bank is not a validity requirement. You can present a valid EPA to the bank after the donor has lost capacity. The challenge is practical, not legal: banks are more cooperative when the EPA has been pre-registered during a calm visit rather than presented for the first time during a crisis.
How quickly can I complete both documents?
With all materials prepared (identification, witness arranged, GP capacity letter), both the EPA and ACD can be executed in a single sitting — typically two to three hours including reading, completion, and witnessing. The kit is designed for same-day completion specifically because the crisis window does not allow for multi-week processes.
What happens if we miss the capacity window entirely?
You apply to SACAT for administration (financial) and guardianship (personal/health) orders. The application requires a comprehensive medical report confirming incapacity, evidence that the proposed administrator/guardian is suitable, and a filing that meets SACAT's procedural requirements. The process takes four to six weeks with complete evidence and longer if the application is returned for corrections.
Can I execute the EPA in a hospital?
Yes, as long as an authorised witness (JP, solicitor, or proclaimed police officer) is available and the donor has legal capacity at the time of signing. The signing environment does not affect the document's validity — only the capacity of the donor and the presence of a proper witness matter.
