If the property is held in joint tenancy, the deceased owner’s stake in the property will be passed on to the remaining surviving joint owner(s).
If the property is held as tenancy-in-common, the deceased owner’s stake becomes part of the deceased’s estate and will not be covered by CPF nomination. If there is a will, the deceased owner’s share of the property will be distributed according to the will. If there is no will, the property share will be distributed based on intestacy law, which is a set of distribution rules predetermined by the law. The CPF money the deceased used to pay for the house doesn’t need to be returned to CPF board.
