I believe I’m the father of this child but the mother had another man sign the certificate. I’ve been in the child’s life, but now she’s keeping him away from me. What can I do legally to prove I’m the father and get visitation?

ANSWER

You could file a Petition for Custody with a separate Request for a Paternity Test in the Circuit Court of the County where the child lives. You should consult an attorney to make sure you add the proper information to your filings.
If the other man is her husband then that presents another layer of complication.
