Hello. My 17 year old daughter has left home against my wishes to reside with a family I do not know. The father at the other residence has contacted my daughter's school and told the school my daughter resides with them now ( custody of children). After a heated conversation with the other parent, I told them they were harbouring my daughter against my wishes and I expected them to send her home to me. They continue to harbour my daughter. What are my rights as a parent in the eyes of family law?
