38 CFR 6.17: Collection of any indebtedness.

At the maturity of a United States Government life insurance policy by total permanent disability or death, any indebtedness, unless paid off in cash, shall be liquidated by reducing the amount of each monthly installment in the proportion which the indebtedness bears to the commuted value of monthly installments as may then be payable under the policy, excluding dividend accumulations. If the policy is payable in one sum at death, any indebtedness shall be deducted from the amount payable under the policy.
