Notary Public and Commissioner for Oaths fees in Singapore, explained

Fees for notarial work in Singapore are not a free market. Both Notaries Public and Commissioners for Oaths operate on statutory schedules, meaning the rate you see at one firm is, by law, the same rate you'll see at every other firm. What differs between providers is only the admin and handling charges they layer on top. Here's a plain-English guide to each schedule and what to watch for.

Commissioner for Oaths fees

A Commissioner for Oaths (CO) witnesses statutory declarations, affidavits, and similar documents intended for use in Singapore. Their fees are set under the Commissioners for Oaths Rules and are charged per occasion, not per page.

• $25 for the first document signed in a single appointment.
• $10 for each additional document signed on the same occasion.
• Page count is irrelevant: a 1-page affidavit and a 20-page affidavit attract the same fee.
• No Notarial Certificate fee. No SAL authentication.

Notary Public fees

A Notary Public (NP) handles documents for overseas use. The fee schedule is set out in the Second Schedule of the Notaries Public Rules and is more granular than the CO scale, because a notarial act requires both the underlying action (certifying a copy, witnessing execution) and the production of a Notarial Certificate that the Singapore Academy of Law then authenticates.

Certifying true copies

• $10 per document for the first page.
• $5 per additional page within the same document.
• $75 for each Notarial Certificate. One certificate can cover multiple documents going to the same recipient.
• $87.20 for each SAL authentication ($80 plus 9% GST, mandatory since October 2019 for overseas use).

Witnessing execution of a document

• $40 for the first signatory per document.
• $20 for the second signatory per document.
• $10 for each additional signatory per document.
• $150 flat per document if the executing party is a company.
• $75 Notarial Certificate per document. Unlike with true-copy certification, witnessing requires a separate certificate for each document (Rule 8, Notaries Public Rules).
• $87.20 SAL authentication per certificate where the document leaves Singapore.

What the statutory schedule does not include

Firms may legitimately charge for costs outside the statutory schedule. These are not price-controlled and will vary between providers, which is why the same document can end up with different final bills:

• Admin or document handling fees, usually a flat charge per engagement.
• Travel to SAL or same-day turnaround premiums.
• Courier, dispatch, or doorstep collection fees.
• Translation services where required.
• GST on any of the non-statutory fees above, if the firm is GST-registered.

When calling or messaging a firm, ask them to quote the all-in price for your specific job: statutory fees plus their handling and any add-ons, so there are no surprises at invoice time.

Quick reference

• Singapore-only declaration (CO): $25 first, $10 each additional.
• Overseas certified passport copy (NP, 1 page): $172.20.
• Overseas witnessing, 1 signatory (NP): $202.20.
• Overseas witnessing by a company (NP): $150 execution + $75 cert + $87.20 SAL = $312.20.
