My belief is moms and dads should agree that they will both ask for 50/50 custody in the case of a divorce. My agreement is more of a set of vows. I have not written a legally binding contract, like a pre-nuptial, that governs the money in the case of the divorce. I have written an agreement that governs the promise between the two parents to share the love and parenting of their children in a balanced way for the rest of their lives.
My ex-wife knows I am paying and will continue to pay my child support until my daughter turns 18. She wants to keep me under the thumb of the "enforcement" of Title IV-D because hurting me gives her pleasure.
