I did my own divorce. The judge told me I wasn't taking enough in child support.
I said, "That may be true, but I want my daughter's father to see her, and if he has money, then he can see her more often." I thought that if I were not a 'bitch', then he'd want to come around and see her. I gave him everything. Little did I know, he had no interest in seeing her grow up. What an arse. I should have taken the money to give her a better life.
I've done divorces for friends. It's not hard. As long as they're simple, anyone can do them. You can ask for whatever you like. It's NOT up to the judge to tell YOU what you can do.
As long as you're in agreement, it works well. You may need a lawyer when you can't agree on terms.
