Courts can throw out pre-nups. Has happened before, at least in the US. Paternity tests have also been ignored by some judges, with their reasoning being, believe it or not "well, you have more money than the real father so it would be better for the child".

Fucking clown show.

Well, I'm in Texas, so as long as both parties sign the pre-nup and the financial state of both parties is properly disclosed, then it will hold up in court. As far as a paternity test, once again, I'm in Texas, so if testing proves I am not the biological father, the court can terminate child support, but I will be responsible for unpaid back support. Besides all of that, I have a great lawyer friend who specializes in these cases. The standard pre-nup contract her firm offers has not been beaten to this date.
