Who Can Witness Documents in South Australia
Table of contents
In South Australia, the correct witness and signing method depend on the document. Statutory declarations, enduring powers of attorney and advance care directives have different rules. A JP can perform authorised services free, but an overseas recipient may require a notary. Some original Australian public documents can instead go directly to DFAT.
Key takeaways
- South Australia sets out who may witness statutory declarations, affidavits, enduring powers of attorney and advance care directives. The lists are not all the same.
- Since 2014, the advance care directive has been South Australia's single document for future health, accommodation and personal decisions.
- An enduring power of attorney covers financial matters only, and has its own form and witness rules.
- JPs provide free authorised services. DFAT will not legalise a copy certified only by a JP.
- For overseas use, determine whether the recipient needs the original, notarisation, DFAT legalisation, or a combination.
Which documents have their own witness rules in South Australia?
South Australia treats witnessing as a safeguard, and it sets rules for each kind of document according to what is at stake. A statutory declaration is a written statement you declare to be true. An affidavit is sworn evidence for a court. An enduring power of attorney hands someone control of your finances, possibly after you lose capacity. An advance care directive records your wishes about health care and appoints people to make decisions for you.
Each has its own form, and the people who may witness it are set out in South Australian law. The lists overlap, and Justices of the Peace and lawyers appear on most of them, but they are not identical. Other state or territory rules may differ. The first step is to identify the document, then check the current list for that document. The South Australian Government publishes the forms and guidance.
Who can witness a South Australian statutory declaration?
A South Australian statutory declaration must be taken by an authorised witness under the Oaths Act and regulations. Current categories include JPs, police officers other than probationary constables, notaries, commissioners for taking affidavits and specified professionals and office holders. The declarant must follow the prescribed process, including identification, signing and the spoken declaration.
The SA Government statutory declaration guide provides the current form, authorised-witness route and face-to-face or online steps. A Commonwealth declaration is a separate instrument, so use the form the recipient asks for rather than inferring it from the witness's occupation. Our guide to who can witness a statutory declaration compares them.
What is an advance care directive?
An advance care directive is South Australia's document for recording your wishes and values about future health care, where you live, and other personal matters, and for appointing substitute decision-makers to act if you cannot. Since 2014 it has replaced the older South Australian documents that covered these matters separately, such as enduring powers of guardianship and medical powers of attorney. Documents made under the older arrangements before the change generally continue to have effect.
An advance care directive must use the approved form and be signed in person before an independent authorised witness. The witness cannot be a beneficiary under the maker's will, an appointed substitute decision-maker, or the maker's health practitioner or paid professional carer. The current SA Health advance care directive guidance provides the approved form and explains the eligibility, independence and certification rules. Our power of attorney and legal declarations guide explains equivalent documents elsewhere.
Who can witness a South Australian enduring power of attorney?
An SA enduring power of attorney concerns financial and legal matters, not the health, accommodation and personal decisions dealt with by an advance care directive. The donor signs the prescribed form before a person authorised to take affidavits, such as a JP or lawyer. A donee cannot witness it. The witness must be satisfied that the donor acts freely and understands the document's nature and effect.
The Legal Services Commission of SA kit explains the form, witness and acceptance requirements. Execution is in person, and land registration has additional original-document requirements. Use the current form and obtain legal advice for complex assets, capacity concerns or family conflict. Our guide to powers of attorney and legal declarations gives the general picture.
Which SA document needs which witness?
The table gives the usual answer. The receiving body's instructions always come first.
| Document | Usually witnessed by | What to check |
|---|---|---|
| SA statutory declaration | A JP, lawyer, notary or other authorised person | That your witness is on the current SA list |
| Commonwealth statutory declaration | Anyone on the Commonwealth list of approved witnesses | That the receiving body wants the Commonwealth form |
| Affidavit for an SA court | A JP, lawyer or other authorised person | The court's rules on form and exhibits |
| Enduring power of attorney | A person authorised to take affidavits; not the donee | The prescribed form, in-person execution and witness certification |
| Advance care directive | An independent authorised witness from the ACD list | The approved form, exclusions and in-person signature |
| Document for use overseas | The issuer, a notary or another witness specified by the recipient | Whether it needs the original, notarisation, DFAT legalisation or a combination |
What does a South Australian JP do?
An SA JP is a volunteer office holder who performs authorised witnessing and certification functions without charging for the JP service. A JP does not give legal advice or accept responsibility for the truth of a declaration. JP status also does not override a document's exclusions. For example, an advance care directive witness must be independent.
JPs are available at community sessions and by arrangement. Before attending, confirm that a JP is eligible for the exact document and whether physical presence is mandatory. For overseas use, a JP certification and a notarial act are not interchangeable. Our guide to witnessing signatures before a notary explains the overseas-document role.
When do you need a notary in South Australia?
Use an SA notary when the overseas recipient requires a notarial act, such as witnessing a signature, administering an oath, verifying authority or certifying a copy. Do not infer that step merely from the overseas destination: eligible original Australian government and public-education documents may be legalised directly by DFAT.
DFAT's document legalisation guidance explains when it accepts an original, verified educational record or notarised copy, and confirms that a copy certified only by a JP is not enough. An apostille or authentication verifies the relevant signature, stamp or seal, not the document's contents or foreign acceptance. Our document notarisation guide and apostille and authentication guide cover the steps.
Can documents be witnessed remotely in South Australia?
Since 1 January 2025, SA statutory declarations and affidavits may be witnessed online under the Oaths Act process, including live audio-visual observation, identity checks, required statements and document transmission. That permission does not extend to every document: certified copies, enduring powers of attorney and advance care directives must still be handled in person.
Remote-witnessing permission does not automatically permit every notarial act by video. For overseas use, the notary must confirm whether the particular act is legally and professionally permitted, and the recipient must confirm acceptance. Our mobile notary guide explains what to ask before arranging attendance.
How do you prepare to have a document witnessed in SA?
- Identify the document: statutory declaration, affidavit, enduring power of attorney, advance care directive, or something for overseas.
- Use the current approved form, and read any notes that come with it.
- Check your witness is authorised for that particular document.
- Follow the signing procedure and do not sign until the official instructions tell you to.
- Bring original photo identification and the originals of anything to be certified.
How much does witnessing cost in South Australia?
JPs do not charge for authorised JP services, and the government forms can be obtained without paying a notary. A lawyer or notary may charge for advice, preparation or professional witnessing. Overseas work may include document review, a notarial certificate, additional signers or copies, travel or urgency, plus separate DFAT, translation, consular and courier fees. Send the complete document and recipient instructions first and request an itemised quote; do not pay for notarisation where an accepted free witness or eligible original public document is sufficient.
What does this look like in practice?
Here is an illustration, not a real case. Rosa lives in Mount Gambier. She wants her son to manage her finances if needed, her daughter to make health decisions for her, and she has inherited a share of a family property in Italy.
She completes an enduring power of attorney for finances and an advance care directive for health and personal decisions using the current forms. An eligible JP witnesses both in person, after confirming the separate certification and independence rules. For the Italian inheritance, the notaio supplies written instructions requiring a separate power of attorney to be signed before an Australian notary and legalised, so Rosa follows that sequence.
In short
In South Australia, match the document, witness and method: statutory declarations and affidavits may use the current online process; enduring powers and advance care directives require in-person execution under their own rules. For overseas use, do not assume notarisation. Follow the recipient's written requirements and DFAT's document rules.

Does an enduring power of attorney cover health decisions in SA?

No. Justices of the Peace in South Australia are volunteers and do not charge for witnessing documents or certifying copies. Many attend community sessions in suburbs and towns, and some are available by arrangement.
Can a South Australian JP certify documents for overseas use?
A JP may certify a copy where accepted, but DFAT will not legalise a copy certified only by a JP. The overseas recipient may instead require an original public document, notarised copy or another specified form. Ask first.
When do I need a notary in South Australia?
When the recipient requires a notarial act such as witnessing, an oath, verification of authority or a certified copy for foreign use. Some eligible originals can go directly to DFAT, so overseas destination alone does not establish a need for notarisation.
Can documents be witnessed by video in SA?
SA statutory declarations and affidavits may be witnessed online under the process effective from 1 January 2025. Certified copies, enduring powers of attorney and advance care directives still require in-person handling. This does not automatically permit a notarial act by video.
What should I bring when a document is witnessed?
Bring the unsigned document on the current form with every page, original photo identification such as a passport or driver licence, and the originals of anything to be certified. Check first that your witness is authorised for that document.
