Article 3 Duration of beneficiaries' pensions
Where a person makes an allocation under these Rules in favour of his spouse, the Treasury may grant to his spouse a pension which—
if the person making the allocation exercises the option to be known as Option A, shall be payable in respect of the period, if any, for which the spouse survives the person making the allocation, or
if the person making the allocation exercises the option to be known as Option B, shall be payable in respect both of the period of their joint lives beginning with the date as from which that person's allocation declaration has effect under paragraph (2) or paragraph (4) of Rule 23 of these Rules and of the period, if any, for which the spouse survives the person making the allocation.
Where a pension is payable for the periods specified in paragraph (1)(b) of this Rule, the rate of pension payable to the spouse during the second period shall be twice the rate payable to the spouse during the first period.
Where a person makes an allocation under these Rules in favour of a dependant (other than a spouse), the Treasury may grant to such dependant a pension which shall be payable in respect of the period, if any, for which the dependant survives the person making the allocation.
