Good news on the marriage bickering front (which everyone does), I think you are right that he won't get a check this month, but a bit off on calling it the wrong thing.

I believe when SSA says that back pay check covers you through the end of March that they are saying that back pay check included payment for March.

That March payment is what your hubby will be looking for the third Wednesday of April.

You got him there. You were just a bit off in your terminology in saying that you think they paid you through April. If they included the payment that you would otherwise expect IN April, they were still just paying you THROUGH March.

My payment FOR March 1-31 will come April 17th. That check comes IN April, but it is FOR March. Does that make sense ?

I apologize in advance if you do "get" that and it's just my hangup on you saying "payment through April" and "paid through". My take on "through" (and the SSA's) is about the benefit period covered and you could just have your focus on when the money arrives, which is reasonable.

I had a similarly confusing issue over when my son's last family benefit check would come when he turned 18 the month after he graduated high school.
