They will have to return the benefit received for the month of death and any later months. For example , if the person died in July then you must return the benefits paid in August . How the benefits are returned depends on how the deceased received benefits.
I think I have other things that I need to know. What happens if I remarry before you turn 60, or 50 and disabled?
You cannot receive benefits as a surviving spouse while you are married.
Can the kids get a lump payout or will it be different if the survivor is not the spouse?
