There is no specific time period you must wait before asking for a modification. However, New York judges typically believe it is in a child’s best interests to have as much consistency and stability in their lives as possible following divorce, so they won’t easily grant a modification soon after the original order was signed. But if a material change in circumstances occurred shortly after the original order of custody or visitation was put in place, and the change negatively impacts the child and proves to be no longer in the child’s best interest, judges may agree to modifying orders.
