Allow the judicial system to do the work. If you are suppose to get some of the bonus, they generally will "order" him to pay the amount by a certain time. If it's not paid, he's in contempt of court and could very well pay a fine and have some jail time. It all depends upon the state and the judge.
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.
