Legal Question in Family Law in Georgia

You could apply for guardianship of the child in the Probate Court of the county where the child resides. If a parent objects to the guardianship, the court will automatically dismiss the guardianship unless the objecting parent does not have legal custody of the child (the parents were not married at the birth of the child, and the father has not legitimated (AS APPEARS TO BE THE CASE HERE); OR the parents are divorced and only one parent has custody of the child). If the objecting parent does not have legal custody, there will be a hearing on the matter. Additionally, the parents may approve of the guardianship, but object to the person applying for guardianship (for example, they want someone else to be the guardian). In this case, there will also be a hearing. The parents have a limited time to object to the court, depending on the method of notice.

It is his daughter! Of course he might be able to take his daughter from a step-grandparent. On what basis do you believe you should keep her from him if he wants to take custody?
