In the state of Texas, my spouse and I share a week on week off custody arrangement. My son goes to daycare at the church/school that my spouse's dad is pastor at and my ex-wife and her parents consistently take him from daycare during lunch during my custody weeks. I have told the school that I do not want anyone, including them, to have contact with him during my custody time, but it has not changed anything. Is she in violation of the custody arrangement? Do I have the right to not allow the visitation? The custody agreement is pretty standard and does not specifically mention this.
