When a Notarial Act Is Invalid

"Invalid" gets used loosely about notarised documents. A foreign registry refuses a certified copy and the client concludes the notarisation was invalid. Usually it was not. The act was sound; the registry wanted something different.

Getting the diagnosis right matters, because the fix is different in each case. This page separates a genuinely defective notarial act from the things that are often mistaken for one.

Three different problems

The notarial act is defective. Something the notary certified did not happen, or happened in a way that undermines the certificate. This is a problem with the act itself.

The act is sound but refused. The certificate is accurate and properly made, but the receiving authority wants other wording, a newer document, a different form of authentication or a particular translation. This is a problem of fit, not validity.

The act is sound but the document is not. The notary properly witnessed a signature on a contract, deed or will that is itself defective under the law that governs it. Notarisation does not repair the document.

Most rejections are the second kind. The first is rarer, and more serious.

Defects that go to the act itself

A notarial certificate is a statement of fact by the notary. It is defective when that statement is untrue, or when the notary could not properly make it.

The signature was not made in the notary's presence. A certificate saying a document was signed before the notary, when it was signed beforehand at home, is false in its central statement.

There was no original. A certificate that a copy is a true copy of an original, when the notary saw only a scan or another photocopy, describes a comparison that never happened.

The signatory was not who they claimed to be. If an impostor was accepted on inadequate identification, the certificate attests to a person who never appeared.

The notary had an interest. A notary who is a party, benefits, or is closely connected to someone who benefits cannot give the independent attestation the certificate implies. Disclosure does not cure it.

Capacity or free will was absent. If the signatory did not understand what they were signing, or signed under pressure, the notarial act may stand as a record of what the notary saw while the underlying transaction is open to challenge. The two questions are related but legally distinct.

The person was not able to act as a notary. An act performed by someone who did not hold a current appointment, or whose authority was suspended or limited at the time, is not a notarial act in the ordinary sense. Whether an act by a notary outside the scope of their appointment is effective is a question for the rules of the appointing jurisdiction.

Defects in the certificate

Some problems lie in the paperwork rather than in what happened:

• no signature, or no seal, where one is required
• no date, or a wrong date
• the signatory's name or capacity recorded incorrectly
• the act described wrongly — "signed before me" where an oath was administered, or a copy described as complete when it was not
• the certificate not properly attached or bound to the document

Where the act itself was properly performed and recorded in the register, errors of this kind can often be addressed by the notary issuing a fresh or corrected certificate. Whether that is possible, and whether the receiving authority will accept it, depends on the error and on the notary's own practice. What a notary will not do is correct a certificate to say something that did not happen.

Defects after the act

A notarial act can be sound when made and compromised afterwards.

Alteration. Anything written on, removed from or substituted in the document after notarisation undermines it. A date added later, a page replaced, a blank completed.

Unbinding. Notaries bind multi-page documents with ribbon, eyelets or seals precisely so that interference is visible. A document that has been unstapled for photocopying looks interfered with, whatever the reason. Receiving authorities will generally treat it as compromised.

There is no repair for either. The act has to be performed again.

What a sound act does not fix

A valid notarial act does not make a document valid. It does not:

• give a company officer authority they did not have
• satisfy execution rules for a deed or will that were not followed
• make the contents of a declaration true
• replace registration, stamping or lodgement the law requires

Where the doubt is about the document rather than the notarisation, the question is for a solicitor in the jurisdiction whose law governs the document, not for the notary.

Who decides

In practice, the receiving authority decides whether to accept a notarial act. Ultimately, whether an act or the transaction built on it is invalid is a question for a court applying the relevant law — which may be foreign law.

A notary cannot declare their own earlier act invalid, and cannot retrospectively validate a defective one.

What to do

If the document has not been used yet, the answer is almost always to repeat the act properly: a fresh signature before the notary, a copy certified against the original, a new certificate. That is quicker than arguing about the old one.

If the document has already been relied on — a property transferred, a company registered, a court filing made — a defect in the notarial act can put the transaction itself in question. Take legal advice in the country where it was used before doing anything else.

Common questions

My document was rejected overseas. Does that mean the notarisation was invalid? Rarely. Get the reason in writing. It is usually a requirement of the receiving authority, not a defect in the act.

Can I fix a problem by having the notary initial a correction? For minor slips, sometimes, if the notary is satisfied the act itself was sound. A clean fresh certificate is usually better for anything going overseas.

Does an apostille mean the notarial act was valid? No. DFAT confirms the notary's signature and seal are genuine. It does not examine whether the act was properly performed.

The notary has since retired. Is my document still valid? Yes. A notarial act made while the notary held office is not affected by later retirement.
