The answer depends on what kind of custody agreement you have. If custody was settled by way of a court order, either by consent or after a hearing, then you will need to file a motion in the cause. This will ask the court to modify the existing order upon a showing of a substantial change in circumstances affecting the welfare of the children.
If there was never a court order regarding custody, you may need to file a lawsuit seeking a custody determination. If there is no prior order, the judge will make a decision based on the best interests of the children.
Good luck!
