HDB statutory declaration: what you need to know

HDB transactions often require a statutory declaration. Here is when you need one, who can witness it, and what it costs.

If you are buying, selling, or transferring an HDB flat in Singapore, there is a good chance you will be asked to make a statutory declaration at some point in the process. This is a formal sworn statement confirming certain facts, and it needs to be signed in front of an authorised witness.

When HDB requires a statutory declaration

Change of flat ownership (adding or removing an owner).
Declaring the relationship between co-owners.
Confirming that you meet eligibility conditions (citizenship, income ceiling, family nucleus).
Declaring the source of funds for the purchase.
Replacement of a lost or damaged title deed or lease.

Who can witness it?

Since HDB statutory declarations are for domestic use within Singapore, a Commissioner for Oaths is sufficient. You do not need a Notary Public unless the document will also be used overseas.

Commissioner for Oaths fee: $25 for the first document, $10 for each additional document signed on the same occasion. Page count does not matter.

What to bring

Your NRIC or passport for identity verification.
The draft statutory declaration. HDB may provide a template, or your lawyer can prepare one.
Any supporting documents referenced in the declaration.

The process

You read the declaration, confirm the contents are true, sign it in the presence of the Commissioner for Oaths, and they countersign and stamp it. The whole thing typically takes 10 to 15 minutes. Walk-in appointments are common at most law firms.

Making a false statutory declaration is a criminal offence in Singapore, so ensure every statement in the document is accurate before you sign.
