38 CFR § 3.450 - General.
(1) All or any part of the pension, compensation, or emergency officers' retirement pay payable on account of any veteran may be apportioned.
(i) On behalf of his or her spouse, children, or dependent parents if the veteran is incompetent and is being furnished hospital treatment, institutional, or domiciliary care by the United States, or any political subdivision thereof.
(ii) If the veteran is not residing with his or her spouse, or if the veteran's children are not residing with the veteran and the veteran is not reasonably discharging his or her responsibility for the spouse's or children's support.
(2) Where any of the children of a deceased veteran are not living with the veteran's surviving spouse, the pension, compensation, or dependency and indemnity compensation otherwise payable to the surviving spouse may be apportioned.
(b) Except as provided in § 3.458(e), no apportionment of disability or death benefits will be made or changed solely because a child has entered active duty with the air, military, or naval services of the United States.
(c) No apportionment will be made where the veteran, the veteran's spouse (when paid “as wife” or “as husband”), surviving spouse, or fiduciary is providing for dependents. The additional benefits for such dependents will be paid to the veteran, spouse, surviving spouse, or fiduciary.
(e) The amount payable for a child in custody of and residing with the surviving spouse shall be paid to the surviving spouse. Amounts payable to a surviving spouse for a child in the surviving spouse's custody but residing with someone else may be apportioned if the surviving spouse is not reasonably contributing to the child's support.
