Legal Question in Family Law in Oklahoma

Re: Motion to Modify

You must file in the same court in which the divorce was granted; in fact, it must go to the same judge. Go to that courthouse, find the clerk, ask them what needs to be done procedurally. You may, however, encounter some issue if your ex-wife contests the motion (often is the case), in which case I'd suggest you consider getting an attorney as you'll want to have some legal argument and precedent in support. Courts don't easily or automatically make such orders without some legal support; i.e., courts are hesitant to limit or remove parental rights.
