Notary Public and Commissioner for Oaths fees in Singapore, explained

A plain-English breakdown of the statutory fee schedules that every registered Notary Public and Commissioner for Oaths charges by law.

Key points

  • Fees are set by law, so every Notary Public charges the same, and so does every Commissioner for Oaths.
  • Commissioner for Oaths: $25 for the first document, $10 for each extra one at the same sitting.
  • Notary Public: a fee for the act, plus $75 per Notarial Certificate, plus $87.20 for SAL authentication where needed.
  • Firms can add admin, courier or translation charges on top, so ask for the all-in price.
In this guide

Notarial fees in Singapore are fixed by law. The only thing that differs between firms is what they add on top, such as admin or courier charges.

Notary Public fees

A Notary Public charges for the act itself, such as certifying a copy or witnessing a signature, plus a Notarial Certificate. If the document needs SAL authentication, that is added too. The rates are set in the Notaries Public Rules.

Certifying true copies

First page of each document

Fee: $10

Each extra page

Fee: $5

Notarial Certificate

Fee: $75. One certificate can cover several documents for the same recipient.

SAL authentication, if needed

Fee: $87.20 ($80 plus 9% GST)

Example

A one-page passport copy with SAL authentication: $10 + $75 + $87.20 = $172.20.

Witnessing a signature

First signatory, per document

Fee: $40

Second signatory

Fee: $20

Each further signatory

Fee: $10

A company signing

Fee: $150 per document

Notarial Certificate

Fee: $75, one for each document

SAL authentication, if needed

Fee: $87.20 per certificate

Example

One contract, one signatory, with SAL authentication: $40 + $75 + $87.20 = $202.20.

What the fixed fees do not include

These extras are not set by law, so they vary between firms:

  • Admin or handling fees.
  • Same-day or urgent turnaround.
  • Courier or doorstep collection.
  • Translation.
  • GST on these extras, if the firm is GST-registered.

Tip

Ask the firm for the all-in price for your job: the fixed fees plus any extras.
