Another question about survivor benefits, what if they were actually receiving benefits and someone got them after the person dies?
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.
