This has the advantage of not subjecting the member's CPF savings to his debts upon his death.This is to protect the member's CPF monies and ensure that the member's dependants receive the monies. Moreover, if CPF monies are distributed according to a will, any disputes arising from the existence and validity of the will may delay the receipt of the CPF monies by the dependants.It is, therefore, in the interests of both members and their dependants for un-nominated CPF monies to be distributed by a public agency outside of the member's estate, in accordance with intestacy laws.If the CPF member wants his CPF monies to be distributed in accordance with a will, the member can make a nomination of the same beneficiaries as those under the will. Upon the member's death, the CPF Board will pay the CPF monies to the nominees directly.
