How to certify a true copy of your document in Singapore

A certified true copy proves a photocopy is identical to the original. Here's what the process actually looks like.

Certifying a true copy is one of the most common notarial tasks: schools, employers, and foreign authorities often ask for a "certified copy" of your passport, NRIC, or qualifications rather than the original. In Singapore the process is quick and fee-fixed.

What you'll need

  • The original document (the notary must see it in person).
  • A photocopy for them to stamp. Many firms will photocopy it on the spot.
  • Photo ID (NRIC, passport or FIN card) so the notary can verify you.
  • An idea of where the copy will be used, which determines whether a Commissioner for Oaths can help or you need a Notary Public.

The steps

  • Book a short appointment with the firm. Most take walk-ins and some offer doorstep collection.
  • Bring the original document plus ID.
  • The notary checks the copy against the original, signs and stamps the photocopy, and attaches a Notarial Certificate (if a Notary Public is used).
  • If the document is for overseas use, the firm will also arrange SAL authentication, usually the next day.
Multiple documents for the same recipient can often share a single Notarial Certificate, so ask the firm to save on costs.

The entire process typically takes 15–30 minutes at the office. Turnaround including SAL stamping is usually 1–2 business days.
