Don't get one. Ever. It's a contract that says if she stops liking you she can take half your stuff. There are no protections for men in said contract and enforcement is ruinous for us. Over 90% of alimony and child support payments go to women. Custody is nowhere near 50/50. Anyone who loves you will love you outside of legal submission to her.
Posted because let's see how well this really works. ;) You can decide for yourself where the troll ends and the reality begins in this one.
