What is the name of your state (only U.S. law)? North Carolina. My sister-in-law packed up her belongs and left her husband and kids. She claims she fell out of love with him and doesn't want to be with him any longer. Since she left her kids with him, he'd like to know what he has to do. And he'd like to know that if she comes back to get them for a visit, does she have to stay in North Carolina or can she go over state lines with them.
