Parental rights go with the biology. Parenthood has nothing to do with marital status. The only way that would be affected is if custody is legally granted to another person-and that can always be challanged. Remember there are two parents involved. So if there is conflict, the rights of each bio parent are equally important. If there is any concern over parental rights, the smart thing to do is contact an attorney immediately and make sure you are within whatever rights you claim to have.
