If the benefits that the grandfather is receiving for the minor child presumably until the child reaches the age of majority (age 18) then if the grandfather who adopted the child passes, the benefits that are for the child should continue.What I do not understand is the Veteran's Administration benefits that the child is receiving unless one of the child's parents was in the military and was killed. Assuming the grandfather passes while the child is a minor and the aunt acts as the child's guardian, then the child's benefits should continue being paid to the aunt as the minor's fiduciary until the child is eighteen (18).
