Divorce decree. It was agreed that (for ex) if my alimony was $1000 a month, and I received $1200 a month from him, but he got $400 from my pension, then it would be $1200-400=$800, alimony still at $200.
But there were months that I just receive his pension of say $1200, which means that he would have satisfied the $1000, and I didn't think I would owe him $200. a month. I think alimony and satisfying those payments are 2 separate things, and as long as I received more in his pension, then I would not be overpaid and owe him money. Does that make sense? I'm trying really hard here.
