Let's begin at the beginning. You said you and the child's mother were never married. That being the case, was your paternity ever established, and are there court orders concerning paternity, custody, visitation and child support? If so, in what state were those orders entered? I'll assume for the time being that appropriate court orders are in place.
What exactly did she sign?It has also come up that the mother "signed over her rights" to our daughter and her son from her husband to her mother in 2021, which I was never contacted about.
As you've been told, that's absolutely wrong.I want to avoid a legal battle and everything I've looked up has basically said at her age she can choose.
For starters, you need to discuss this with the mother. If she's agreeable, then it should be a simple matter to have an attorney prepare a stipulated modification to the custody order. If she doesn't agree, then you'll have to petition the court for a change of custody. You'll need to convince the court that circumstances have changed and that it's in the child's best interests to change custody. The court will probably consider your daughter's preference, but it won't be controlling.Do I have a leg to stand on here?
