I Have Physical Custody of My Child, and My Ex has Visitation. Is My Ability to Relocate with the Child Restricted?

It depends on the facts of your case and the specifics of your custody/visitation arrangement.  A court would seek to determine what is in the best interest of the child and whether or not the move would substantially impair the relationship between your child and the other parent. Reclocation cases are some of the most divergent in outcomes and are incredibly dependent on the operative facts and manner of presentation.
