If you have children and think you may want to move in the near future, make sure you have a solid plan in place before you file for divorce. The court will look at the locations you and your spouse intend to live when making the initial determination regarding parental responsibilities. Make sure your plan is unambiguous so the court does not question whether and where you will move. Keep in mind that it is generally more difficult to obtain your ex-spouses or court approval to move after a divorce is final and a parenting plan has already been put in place.
If you think your spouse wants to move, and you do not want your children to move, you should consider filing for divorce sooner rather than later and you should start gathering as much evidence as possible to show that staying put would be the best thing for your children.
Whatever you do, do not move out-of-state with your children before you file, unless you have your spouse's written consent. There is a very real possibility that the court could order you to return the children to Oklahoma and you could jeopardize your future parenting time.
