38 CFR § 3.451 - Special apportionments.
Without regard to any other provision regarding apportionment where hardship is shown to exist, pension, compensation, emergency officers' retirement pay, or dependency and indemnity compensation may be specially apportioned between the veteran and his or her dependents or the surviving spouse and children on the basis of the facts in the individual case as long as it does not cause undue hardship to the other persons in interest, except as to those cases covered by § 3.458(b) and (c). In determining the basis for special apportionment, consideration will be given such factors as: Amount of Department of Veterans Affairs benefits payable; other resources and income of the veteran and those dependents in whose behalf apportionment is claimed; and special needs of the veteran, his or her dependents, and the apportionment claimants. The amount apportioned should generally be consistent with the total number of dependents involved. Ordinarily, apportionment of more than 50 percent of the veteran's benefits would constitute undue hardship on him or her while apportionment of less than 20 percent of his or her benefits would not provide a reasonable amount for any apportionee.
