Every government servant should submit nomination in the prescribed form immediately on joining the Fund. While an employee not having family may nominate any other person, the nomination should be in favour of family member(s) only in the case of one having family. The subscriber may provide in the nomination that the nomination shall become invalid in the event of the happening of a contingency specified therein e.g. a bachelor may nominate his father or mother. He can specify in the nomination that the nomination will become invalid in the event of his subsequently getting married. If the nomination is made in favour of more than one person, the proportionate share in which the amount will be payable should be specified clearly in the relevant column. At any time, the nomination may be canceled by the government servant.
