Ex & His wife gave me guardianship....

What is the name of your state? What is the name of your state? Tennessee

Now they want my son back! Is there anyway I can stop them? I live in Tennessee they live in California. Three years ago they gave me guardianship of my son (they had parental rights taken away from me in 1994) She sent my son to me after she discovered that he(ex) was physically abusing my son. She admits he had been verbally and emotionally abusive for years. My son told her that the physical abuse had been happening for a long time before she found out.
She divorced him, gave me my son and had her lawyer draw up papers that gave me guardianship as long as it was in my sons best intrest. Now, it seems they are getting back together and thay want my son back. He says he is taking him back to California July 5th. What can I do to stop them?
Last year she got him to agree that if I were to adopt my son, they would not contest it... I went to a lawyer, it would cost $1500. just to start! I dont have that kind of money nor can I get that kind of money! Is there a way to fight them without money?

Your post is confusing. For starters - if he's your son, why do you need to adopt him?

Sorry for the confusion...
He is my Bio Son; However, My sons father and his,(now ex)wife had my parental rights terminated in 1994.
Does that help make it more clear?
I have been told I must go through the adoption proceedure to regain parental rights.

My brother had a son with a woman and we terminated her parental rights. It is not a common thing to do unless there is an adoption. In La. the only right that remained at all was his right to inherit ( La. is strange about inheritance ). I raised him like my son, and consider him so. You would have to adopt your son as he legally has no mother. However, I would get physical proof and/or find a paper trail that can prove that he was abused. It will be very hard to do as you would have to show them that your environment would be beneficial and his fathers' would be harmful. You will need a very good attorney. If you are very lucky one might do it pro bono. Try legal aid, they might know a group that they can refer you to. Good luck!
