My sons mother (ex-girlfriend) thinks she can keep my son from me due to me not getting him when she wants me to, can she do so?

Go back to court let the judge know you too can not agree and the judge will make an order, you shuld consult a attorney.

Me and my hussband are separated buy not legaly and the state is trying to say i have to push him for child suport

If you re receiving aid, they are entitled to seek reimbursement from him.

Custody of my daughter

Talk to your bf, maybe he will help you hire an attorney

When my daughter was born I was married to another man

More than likely since if your bf was ordered to pay support by a court, there had to be a finding of paternity.

My child's father is willing to sign his rights over do I have to be married or can my boyfriend adopt her?

No I believe in most jurisdictions you have to be married first. Las Vegas here we come.

Is it possible for him to get out for the birth of his child?

That is entirely up to the court and sentance he receives, and then up to the Army.

I have a waiver of spousal support signed and notarized. Does this have to be submitted to court to be valid in Louisiana?

Take it to the court and have it entered, play it safe.

Do I have any legal recourse if my ex lost his job and has stopped paying spousal maintenance?

yes he still owes and you can seek that money in the future, it does not end the order, unless he goes back to court and seeks to have it modified

Grandmother lived with uncle. after she died, family items stayed. now he passed. do I have any rights to her items

You need to check with an attorney, but it appears your uncle was closest in line and blood and that would trump a grandchild.

It sounds as if she is getting coached by someone, you need to see an attorney.
