I am in the process of divorcing my two daughters father in Texas. He has been incarcerated for the last two and a half years for revocation of probation. He was originally on probation for indecenty with a child by exposure. Is there any way I can have his rights terminated and if so do I have to hire a lawyer? Do his parents have any rights' to my girls? His parents are threating me and harrasing my family about my girls. Any information anyone can provide for me would be a tremendous help.
