I just discovered that I am the father of a wonderful girl whom I had no idea she was alive until recently.the grand parents have third party custodybecause the mother is a screw up and lost her daughter on grounds of child adbandoment.it has been proven that I am the father and have been placed on the birth cirtificate and child support has been established.I am in contact with my daughter,and have traveled to their home,but the grand parents are limiting the time,and ill not alow a visit to my home. They are becoming increasingly difficult and I am getting frusterated with the situation.ther has never been anything saying I can't make disisions in my daughters life. What kind of rights do I have in this situation?? thank you
