Your h is trying to pull rabbits, not out of a hat, but through a keyhole. He's desperate and he's going to dig his own grave deeper and deeper all by himself. Now he's gone and screwed your lawyer over and lawyers don't take kindly to not having money put into trust accounts when they are suppose to.
I know it's difficult, but you have to step back and really look at what your h is trying to accomplish. He's trying to say that if he gets married, the maintenance will stop, which we all know it's you, if you get remarried. He's really looking more stupid by the day.
I've got a nice bag of popcorn for you and I want you to come sit down on the curb w/us. The show is just starting and we need to sit quietly and wait for the ending.
Hang in there!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
