I don't think the trial will be that bad. Your lawyer should be able to walk you through. Family matters are different. When you are dealing with someone who is so narcissistic, I think it is inevitable. If you have never googled negotiating with a narcissist, then you should. They literally aren't capable. He needs the judge to tell him how it is going to be.

The lawyer in me says go with your lawyer. The woman in me says do the honorable thing, even if they didn't. It isn't a lot of money and could make look bad with the judge. My guess is that he will reveal what an a$$ he is by himself and you pointing this out only sullies you.
