My daughter and her husband split due to infidelity on her part. They have joint custody. He has since taken their 2 year old baby out of the state without her permission and left the baby with his sister and mother and returned to work in VA (Marine Corp.) They have a temporary custody hearing and we have heard from a detective that he has accused her of drug use and neglect. She has had some drug problems in the past but swears she is clean now. Can they require a drug test at the hearing. Also her husbands sister may petition for custody. Can I or her mother petition for custody and if so would we be required to submit a drug test at the hearing. Should I get a preemptive test for us and my daughter. I have no criminal record of any kind. Any advice would be appreciated.
