I have physical custody of my 2 daughters (8 &6). My x-husband has visitation every other weekend, 2 weeks in the summer, and alternate holidays. He lived is a town 1.5 hrs away and is now planing to move to a town in AZ . ( a distance of 10.5 hrs away. Our current parenting plan states that I deliver the girls to his parents home on Friday @ 6pm, He returns them to me Sunday @ 6. Will I still be required to deliver the girls to his parents home if he is not there or will I have to travel every other weekend to AZ?
