A statutory declaration is a signed statement made under oath. Here's what you should know before you sign one.

  • Making a false declaration is a criminal offence.
  • Fee: $25 for the first declaration, $10 for each extra one at the same sitting.

A statutory declaration is a written statement of facts that you sign and declare to be true, in front of someone authorised to witness it. It is not a court affidavit, but it carries similar weight.

Common uses

  • A change of name, marital status or address.
  • A lost document, for example before replacing a passport.
  • HDB, CPF or immigration applications.
  • Supporting your position in a commercial or family matter.

How it works

  1. 1You, or a lawyer, write the declaration: short, factual statements in the first person.
  2. 2Bring it with photo ID to a Commissioner for Oaths.
  3. 3Read it and sign it in front of them, confirming it is true.
  4. 4They countersign, stamp and record it.

Which witness?

A Commissioner for Oaths is usually enough. If the organisation has asked for the declaration to be notarised, use a Notary Public instead.

Fees

Fixed by law: $25 for the first declaration at a sitting and $10 for each extra one. If you need help writing it, the firm will quote that separately.
