Buying, selling or transferring an HDB flat? You will probably be asked to make a statutory declaration: a formal statement of facts, signed in front of an authorised witness.

When HDB asks for one

  • Adding or removing an owner.
  • Declaring the relationship between co-owners.
  • Confirming you meet the eligibility conditions, such as citizenship, income ceiling or family nucleus.
  • Declaring where the money for the purchase comes from.
  • Replacing a lost or damaged title deed or lease.
