Yes hire a family law attorney skilled in trial work
Evidence needs to be perpetuated and that takes time and an investigation. Don't wait. Save money by hiring a lawyer. Good luck.
This is a complicated matter. Both you, as parent, and your mother, as grandparent, have rights. Your rights supersede a third parties'. Now, you may have to bring all of this to the court's attention, and it would be in your, and your child's, best interest to retain an attorney to advise and represent you.
You should consult with an experience South Carolina child custody lawyer.
You should discuss with your attorney what your rights might be. Your legal rights as the father will depend on whether you were married to the mother at the time of the birth. Alternatively, if you have filed a paternity case to have your legal rights determined as a father, your legal position will be stronger.
You have my best wishes.
