I have legal guardianship for my partner. He passed away on August 22, 2019. He received his SSA benefits on the 3rd of every month. If SSA benefits are paid a month behind, then the benefits he received in August would have been for July. However, SSA states that he wasn't entitled for monthly benefits beginning August 2019. My question is this...he didn't receive any benefits on 09/03/19. Why would we need to pay back the benefits received on 08/03/19?
