If you have an existing court order regarding custody and visitation, depending on what it states, you may be able to file for contempt. If it does not have a clause in the existing order that will allow you to file for contempt or enforcement, you may need to seek advice from an attorney to see if you can file for a modification of the existing order to include a clause that will prevent the mother from constantly calling your daughter during your visitation with her. It will all depend on what your existing court order states.
