Beneficiary on the policy at time of death. Default is "by law" order: spouse > children > parents > estate.
Different from DIC which is a recurring monthly compensation. SGLI/VGLI is a one-time lump-sum from life insurance.
Survivor + dependent benefits are administered by the U.S. Department of Veterans Affairs. Always verify current eligibility + amounts at va.gov/family-and-caregiver-benefits before filing. CVSOs (County Veterans Service Officers) and VSOs (American Legion, VFW, DAV) file these claims for surviving spouses at no cost.
