Section 51

If a person dies during any period for which he is entitled to any of the cash benefits (or when he is entitled to invalidity grant) provided under this Act, the amount of such benefit (or grant) shall be paid to any person nominated by the deceased person in writing in such form as may be specified in the regulations or, if there is no such nomination, to the heir or legal representative of the deceased person:

Provided that the amount of cash benefit shall be payable up to and including the day of his death in case of disablement benefit (and constant-attendance allowance, if any) and dependants’ benefit and survivors’ pension and up to the last day of the month preceding the month in which the pensioner dies, in case of invalidity pension (and constant-attendance allowance, if any).
