The answer depends on whether or not there is a current court order and, if so, whether that order states who has the decision-making authority. If there is only an informal agreement that has never been approved and adopted as a court order, the custodial parent can move regardless of what the agreement says, but at the risk of consequences if a court becomes involved and chooses to enforce that agreement. If the agreement has been approved and adopted as a court order, the custodial parent risks being held in contempt by failing to abide by the agreement. Even if there is a court order stating that education and/or relocation is a joint decision, the fact is that 1-1 is a tie and it will be up to the court to become the tie breaker.
