If you were to go to Court it would review the present relationship that your spouse has with the children and whether that relationship would be impaired by a move to MA. The best interests of the children will be the determinative factor.
I suggest you try mediating this matter with your spouse and try resolving the issue out of court.
If you are living in the NYC Metro area, please call me at 212-370-1660 to discuss mediation.
