In any case in which child support payments or child and spousal support payments are owed by a member of one of the uniformed services (as defined in section 101(3) of title 37) on active duty, such member shall be required to make allotments from his pay and allowances (under chapter 13 of title 37) as payment of such support, when he has failed to make periodic payments under a support order that meets the criteria specified in section 1673(b)(1)(A) of title 15 and the resulting delinquency in such payments is in a total amount equal to the support payable for two months or longer. Failure to make such payments shall be established by notice from an authorized person (as defined in subsection (b)) to the designated official in the appropriate uniformed service. Such notice (which shall in turn be given to the affected member) shall also specify the person to whom the allotment is to be payable. The amount of the allotment shall be the amount necessary to comply with the order (which, if the order so provides, may include arrearages as well as amounts for current support), except that the amount of the allotment, together with any other amounts withheld for support from the wages of the member, as a percentage of his pay from the uniformed service, shall not exceed the limits prescribed in sections ^[1] 1673(b) and (c) of title 15. An allotment under this subsection shall be adjusted or discontinued upon notice from the authorized person.
