To be granted a modification in your custody agreement, you must be able to prove that a substantial change has taken place which significantly affects the child's stability. This would be things like a geographical move, substance abuse or neglect. Either parent may file for a custody modification, but they must be able to prove to a court that it is in the child's best interest. However, it's not necessary to prove substantial change in circumstance in requests for temporary modifications.
