Under the HDB's prevailing policy for divorce (not due to
non-consummation of marriage or annulment or break-up of Fiancé /
Fiancée relationship), a divorced party who has the custody of
the child (including care and control) is allowed
to retain the flat subject to the eligibility
conditions.
If there are no children from the marriage, the
divorced party (flat owner) may retain the flat under the Single
Singapore Citizen (SSC) Scheme, provided:he / she is a Singapore
citizenhe / she is at least 35 years oldthe matrimonial flat must
be a resale flat purchased from the open market without
the CPF Housing Grant for Family.
If the matrimonial flat is bought directly from HDB
(including resale flats bought with the CPF Housing Grant for
Family), the 5-year minimum occupation period (MOP)
must be satisfied before the divorced party is allowed to take over
the flat under the SSC Scheme.
Alternatively, the divorced party may include another person to
retain the flat, subject to the prevailing eligibility criteria and
eligibility scheme regardless of the occupation period.
If the divorced owners wish to resell their flat in
the open market, they must have completed the MOP for the
flat, as at the date of divorce completion. If the divorce is
within the MOP and none of the owners is eligible to retain the
flat, the owners may have to return the flat to HDB, subject to
HDB's approval. The compensation for the return of flat will be
determined by HDB.
