38 CFR 6.5: Conditional designation of beneficiary.

If the insured by notice in writing to the Department of Veterans Affairs during his or her lifetime has provided that a designated beneficiary shall be entitled to the proceeds of United States Government life insurance only if such beneficiary shall survive him or her for such period (not more than 30 days), as specified by the insured, no right to the insurance shall vest as to such beneficiary during that period. In the event such beneficiary fails to survive the specified period, payment of the proceeds of United States Government life insurance will be made as if the beneficiary had predeceased the insured.
