Legal Question in Family Law in Maryland

Until there is a court custody order or an agreement in place, she is not prohibited from doing this. If this is an imminent concern you need to file an emergency petition on this issue. If you are fighting custody and other child-related issues and don't have an experienced family attorney representing you, you are making a mistake which you could well come to regret down the road. It's much easier to achieve the result you're looking for now than to try and undo what a court did that you are not happy with.
