My daughter has filed for sole custody of my 9 month old grandson but does not have a court date yet. His father went to CA shortly after the child was born and completed his second rehab. They have never been married. He chose to stay in CA and has not provided anything, monetarily or otherwise, for support. The fathers mother and grandmother keep the child during the week while my daughter works. They announced they are taking the child to CA to see the the father. He is paying for their trip. We do not know where or how he lives or works, or if this stint in rehab was successful. I am concerned for the well being of this child and the peace of mind of my daughter. The fathers mother and grandmother are not forthcoming with information about the trip. What rights does my daughter have concerning this trip? Should it be allowed? She doesnt even know where her son will be. She is working and going to college and is providing sole support for her child.
