Commissioner for Oaths in Singapore

For documents that stay in Singapore, a Commissioner for Oaths is usually all you need, and it costs less than notarisation. Knowing which applies is worth a moment.

A Commissioner for Oaths administers oaths and takes declarations for documents used within Singapore. It is a different appointment from notary public, and for the documents it covers it is the cheaper and entirely correct choice.

The fee does not depend on length

Unlike certified copies, this is a flat fee per document however many pages it runs to. Additional documents at the same appointment cost less again.

When it is not enough

If the document is leaving Singapore, a Commissioner for Oaths is very unlikely to satisfy whoever receives it, whatever the form says. Overseas forms frequently ask for “a Commissioner for Oaths or equivalent” because they were drafted for a domestic reader and did not anticipate being signed in another country.

That single misunderstanding is the most common reason someone pays twice. If there is any doubt about where the document is going, ask before you sign.

How we help

How we help

Confirm this is the right and cheaper option

For documents staying in Singapore it usually is. Being told that, rather than being sold notarisation, is the point.

Administer the oath or take the declaration

A short appointment, and a flat fee per document however long it runs.

Do several documents at one attendance

Additional documents at the same appointment are charged at a lower rate.

Warn you when it will not be enough

If there is any prospect of the document going overseas, we will say so before you sign rather than after it is rejected.

Questions people ask

How is this different from a notary public?

Different appointment, different fee, and different reach. A Commissioner for Oaths covers documents used within Singapore. A notary's signature and seal are recognised abroad.

Does the fee depend on the length of the document?

No. It is a flat fee per document however many pages, which is the opposite of how certified copies work.

My overseas form asks for a Commissioner for Oaths. Is that fine?

Probably not, and this is the most common way people end up paying twice. Forms drafted abroad often ask for a Commissioner for Oaths without allowing for the document being signed in a different country. If it is leaving Singapore, assume a notary is needed and check.

Can the same person act in both capacities?

Many practitioners hold both appointments. What matters is which capacity applies to your document, because it determines the fee and what the certificate says.
