You cannot just move away with your child if there is an existing child custody agreement, especially if you are moving out of state. A modification to the custody agreement must be requested and approved by the family court judge. The best interests of the child must be determined before any action to move the child is taken. You could be held in contempt of court for violating an existing court custody order if you relocate a child without completing the required process. It’s always best to discuss your situation with an attorney before making any plans to move.
