Relocation and Modification of Parenting Plans
Generally speaking, neither party can relocate the minor child out of state without the consent of the other party or a court order. Your son does NOT get to choose which parent he lives with. Your ex-wife will have to file a motion with the court requesting that she be allowed to relocate with your son. I assume the court will appoint a Child and Family Investigator to conduct an evaluation and make a recommendation. It is likely the court will also order you to mediation. If you cannot reach an agreement, the court will set the matter for a hearing.
