I'd be pissed, too, BFA. I hope that'll be the first thing you do is tell whoever hears that case, assuming it even gets as far as a courtroom, the actual facts that you've seen first-hand. I have this feeling that recounting your version of the story to some of the adult welfare organizations or in the early depositions, if it gets that far, will be key to blasting his baseless lawsuit out of the water. Your dad has a lot of nerve, especially when he hasn't even been around. You're a nice daughter/sister to be so supportive of your mom and brother!
