I want to up all legal right to pursue legal action against my male partner before I give birth to my unborn child. How do I go about doing that? I mean I want it in written form that I give up the right to sue him for any type of child support or any type of care to my child. Also I don't want to him be involve in the child life or pursue legal actions against me for parental right after the child is born.

I know it's crazy but I really want a child at my age 40 and well finically secure I don't need a man supporting me or my child.

Are you separated from him?
What does he say about the baby?

You can not give up legal rights for a child that is not born, you can work up a contract that will offer serious penalties if the other party violates it.

You need to go to a family attorney have have them draw up the best contract they can.

And even that may not be sufficient if, for example, you ever get seriously disabled and need to go on welfare. At that point, the state will want to know who dad is so that they can get him to pay for the kid.

He and I agree to it but we want it in an almost legal form... He and I are not together any longer and he agree to what I want I just want it written down that he's giving up his parental right to the child.

All he has to do is stick to the agreement you two write up
It doesn't have to involve signing away any rights just that he agrees to stay away.
You should consider the child's feelings though

My one son had very extreme emotional problems from not having a father.

That's the problem I'm scare that he won't keep to his words and he's scare that I won't keep to my words.

If you both write up an agreement, sign it and notarize it or whatever legal procedure it needs but it couldn't involve 'signing away rights'.
But if you are afraid neither one of you will stick to it then even signing away rights wouldn't keep him away.
I know girls that have had PFA's on a guy and had him arrested and next thing you know he is back in the house even with the pfa... so a piece of paper isn't going to work magic.

First, I am not a lawyer. But, I have heard that the custodial parent can't waive the child support, since that is a right that the child has, not the parent. So I am not sure that any contract between the two adults waiving child support is actually legal.
