They are not going to take him to the pokey for one parking ticket! What's done is done, but don't enable him. He screwed up, well, more than once, he has to pay the price. Unfortunately, you are going to pay too, directly or indirectly.
I am afraid that someday soon you are going to have to talk to a lawyer to protect you and the kids. The courts are going to make sure he pays the CS. No one is looking out for you. I'm also scared that he could be piling up debt that is going to follow you around. I know you don't want to do it, but his financial troubles could impact you and the kids, fairly or not.
