Moving to Another State With Shared Custody

Relocating with a child under an existing custody arrangement isn't just a personal decision, it's generally a legal process, with real consequences for skipping it, even if you have primary physical custody.

Check your state's notice requirement first

Most states require the relocating parent to give the other parent formal written notice before a move that would significantly affect the custody arrangement, commonly somewhere in the range of 30 to 90 days, with several states specifying an exact number, 45 days in some, 60 in others. The notice typically has to include specifics: the new address, the reason for the move, and often a proposed revised custody schedule. Skipping this step, even for a move you're confident is reasonable, can create legal exposure independent of whether the move itself would have been approved.

Whether a specific move even counts as a "relocation"

Not every move triggers these requirements. Most states define relocation using a distance threshold (commonly somewhere around 50 miles, though this varies significantly by state) or a duration threshold, rather than treating any move as a relocation. Check your specific state's definition, a move across town and a move across the state can be treated very differently depending on where the line falls locally.

If the other parent objects

If the other parent doesn't consent to the move, many states require them to formally object, often by filing a motion, within a set window after receiving notice. If that happens, the move typically can't proceed as planned without either the other parent's eventual agreement or a court's approval, decided based on whether the move serves the child's best interest.

How courts generally weigh a contested move

Most states apply some version of a best-interest-of-the-child standard to a contested relocation, weighing factors like the reason for the move, the distance involved, the child's age and relationship with each parent, the impact on the child's stability and schooling, each parent's ability to maintain a relationship with the child post-move, and each parent's history of cooperation. No single factor typically controls, and which factors matter most, and who bears the burden of proof, varies by state. See our California guide for a detailed look at one state's specific standard (the LaMusga and Burgess factors) as an example of how this plays out in practice.

Plan the custody schedule around the move

If a move does go forward, whether by agreement or court order, the regular custody schedule usually needs to change to reflect the new distance between homes, see how to choose a custody schedule for how distance factors into which patterns are realistic.
