Notarising Documents When You Have a Disability

Having a disability does not stop you from getting a document notarised. What the notary must be satisfied of is the same for everyone: who you are, that you understand the document, and that you are signing freely. Most disabilities only change how that is shown: reading the document aloud, using an Auslan interpreter, or signing by mark.

Key takeaways

• A disability is not the same as a lack of capacity. The notary asks whether you understand this document, not what your diagnosis is.
• If you are blind or have low vision, the document can be read to you, and the notary may record that it was.
• If you are Deaf, an Auslan interpreter, ideally an independent one, lets the notary speak with you directly.
• If you cannot write, signing by mark or by another person at your direction may be possible, but the rules differ and the receiving authority decides what it accepts.
• A supporter can help you communicate, but the decision to sign must be yours.
• Tell the notary before the appointment what you need. Most adjustments are simple once they are planned.

What does a notary actually need to be satisfied of?

When an Australian notary witnesses a signature or administers an oath, three things matter. The notary must be satisfied of your identity. You must have the capacity to sign, meaning you understand the document and what signing it does. And you must be acting freely, without pressure from anyone. The notary does not certify that the contents of the document are true, and does not decide whether the document suits your purpose.

The Attorney-General's Department sets out a similar test for people witnessing a Commonwealth statutory declaration. Its information for witnesses asks the witness to be satisfied the person understands what they are doing and is not being coerced. A Justice of the Peace applies that test for Australian documents. A notary applies the same ideas, with more formality, for documents going overseas.

None of those three questions is about disability. A person who is blind, Deaf, uses a wheelchair or communicates with an electronic device can satisfy all three. The adjustment is in the method, not the standard. Our guide to how a notary checks capacity and duress explains the checks in more detail.

Is a disability the same as lacking capacity?

No, and this is the point most worth knowing. Capacity is decision-specific: it asks whether you can understand this particular document, weigh what it does and communicate your decision. A person with an intellectual disability or a brain injury may well have capacity for a simple consent letter. A complex property transaction might need more care.

A careful notary will talk with you in plain language and ask open questions, such as "what does this document let your brother do?" If the answers show you understand it, the notary can usually proceed. If they do not, the notary will decline, and that decision protects you as much as anyone.

For a power of attorney or a property document, where capacity might later be questioned, a solicitor may suggest a medical opinion close to the signing. That is a legal judgement for your solicitor, not something a notary requires of every person with a disability. Our guide to powers of attorney before a notary covers the notary's part in those documents.

What if you are blind or have low vision?

You can sign a document you cannot read, as long as you know what it says. Usually the document is read aloud to you in full before you sign, by the notary or someone you choose. The notary must be satisfied that what was read matches the document. Some notaries add a statement to the notarial certificate recording that the document was read to you and that you appeared to understand it. That note is useful to an overseas authority, because it explains why the signature may look different from your usual one.

If you use a screen reader, ask for an electronic copy well before the appointment. The version you sign, though, must be the actual document the receiving authority wants, not a large-print or Braille version, unless that authority says otherwise. A signature guide or card can help you place your signature in the right spot.

What if you are Deaf or hard of hearing?

The notary needs to have a real conversation with you about the document, so communication has to work both ways. For many Deaf people that means an Auslan interpreter. NAATI certifies interpreters, including in Auslan, and keeps an online directory of practitioners. An independent, credentialled interpreter is usually better than a family member. The notary needs confidence that the answers are passed on accurately and that no one is steering them.

A notary may ask the interpreter to confirm their name and credential, and may record those details. People who are hard of hearing may manage with a quiet room, a hearing loop, captioning on a video call, or written questions and answers. Say which works for you, because the notary's job is simply to be confident you understood.

What if you cannot write or hold a pen?

Several options exist, but they are where you need to be most careful. The traditional one is signing by mark. You make a mark such as a cross, and the notary records that it is your mark, made after the document was explained to you. Another is a signature made by another person at your direction and in your presence, which some Australian forms allow with specific wording. A third, where you can make any consistent mark, is simply to sign in whatever way you can; a shaky or unusual signature is still your signature.

Whether each option is acceptable depends on two sets of rules. Australian state and territory rules differ on which documents can be signed by mark or by direction, and some forms have their own wording. And if the document is going overseas, the receiving authority decides whether it will accept a mark or a directed signature. Ask it first. For a will, a power of attorney or a property document, speak to a solicitor before the appointment, because an incorrectly executed document may not be valid.

Situation	What usually helps	What to check first
Blind or low vision	Document read aloud in full; electronic copy in advance	Whether the certificate should record the reading
Deaf or hard of hearing	Independent Auslan interpreter, hearing loop or written exchange	Who arranges the interpreter and their credential
Cannot write or hold a pen	Signing by mark or a directed signature	Whether your state rules and the receiving authority accept it
Speech disability	Communication device, board or written answers	Extra time; the notary may ask more questions
Intellectual or cognitive disability	Plain-language explanation; time; a supporter	Whether a solicitor suggests a medical opinion
Limited mobility	An accessible venue, travel to you, or video	Whether the receiving authority accepts remote signing

Can a supporter, carer or family member help?

Yes, and many people bring one. A supporter can help you get to the appointment, help you communicate, and reassure you. What a supporter cannot do is make the decision for you or answer the notary's questions on your behalf. The notary may ask to speak with you alone for part of the appointment, with an interpreter if you use one. That is routine, not an accusation.

A supporter is also not usually the right person to interpret, particularly if they benefit from the document. A substitute decision-maker is different again. Someone who holds a valid power of attorney or guardianship order for you may be able to sign some documents under that authority. The notary will check their papers. Whether that authority extends to the document in question, and whether it is recognised in another country, are questions for a solicitor.

What if getting to an office is the hard part?

If stairs, distance or fatigue make an office visit difficult, ask about the venue before you book: step-free entry, parking close by, and a room where you can sit comfortably. Some notaries travel to a client by arrangement, and our mobile notary services page explains how that kind of appointment generally works. Ask what is possible for your location rather than assuming.

A video appointment can also help, but only where the receiving authority accepts a remotely witnessed document, and many overseas authorities still want the signer physically present. Check first. Our guide to remote notarisation in Australia explains the limits. If you cannot sign at all at the moment, for example during a hospital stay, our guide to when the signatory cannot attend sets out the usual alternatives.

How do you prepare for the appointment?

1. Check what the receiving authority wants. Confirm it needs a notary, and ask whether it accepts a mark, a directed signature or a remote session if you might need one.
2. Tell the notary what you need when booking. Interpreter, reading aloud, extra time, venue access or a video option.
3. Arrange the interpreter early. Agree who books the Auslan or language interpreter and have their details ready.
4. Send the document in advance. So you can review it in an accessible format and the notary can check the wording.
5. See a solicitor for legal documents. Especially for a will, a power of attorney, a property document, or where capacity might be questioned.
6. Bring ID, the original document and any authority. Photo ID (see accepted ID if you do not drive), plus any power of attorney or guardianship order.
7. Allow time. Interpreting and reading aloud take longer.
8. Plan the next step. If the document needs an apostille, DFAT verifies the notary's seal afterwards.

Common mistakes to avoid

The most common mistake is not mentioning the adjustment until the appointment starts. Then there is no interpreter, no time to read the document aloud, or no step-free entry. The second is using a relative who benefits from the document as the interpreter; the notary may not be able to proceed, because they cannot be confident the answers are yours. The third is assuming that an overseas authority will accept a mark or a directed signature because an Australian form does. It may not, and the authority's answer is the one that counts. The fourth is treating a refusal as the end of the matter; ask what would help, such as a plainer explanation, a different time of day or a solicitor's involvement. Our guide to when a notary can refuse explains the grounds.

Here is an illustration, not a real case.

Dev is Deaf and needs to sign a declaration for a bank in the United Kingdom about an account he holds there. When he books, he says he uses Auslan and will bring a NAATI-certified interpreter. He emails the declaration ahead so he can read it at home. At the appointment the notary speaks with Dev through the interpreter, asks him to explain in his own words what the declaration says, records the interpreter's name and credential, and witnesses his signature. His partner waits outside for that part, which Dev had been told to expect.

In short

A disability does not stop you from getting a document notarised. The notary must be satisfied of your identity, your understanding and your free choice. A document read aloud, an Auslan interpreter, a communication device, or a mark where accepted, can all show that. Tell the notary what you need when you book, check with the receiving authority before relying on a mark, a directed signature or a video session, and see a solicitor for wills, powers of attorney and property.
