You know what I had a friend go through exactly what you have. but just in a different state. The dad did write a letter and she took it with her, when she moved. but he called and said kidnapping. they hunted her down and got her for it. when she went to court the judge said why did yall not come to court and have this documented in file that the dad said you can take the child with you to live. But like i said this happen in Arkansas. and every court is different. What i would do is when i go down there go ahead and make a court date. see the judge and take the dad with you and both tell him what you are wanting to do. and let him put all of this on file. so there will be no complications with anything... best of luck .
