A judge may restrict a parent's access to a child under certain conditions, such as a parent with mental health problems, especially if they are untreated. Drug or alcohol addiction, a history of domestic violence, child neglect or sexual misconduct may also prompt a judge to order supervision when a parent interacts with children. A request to impose supervised time sharing can come from the other parent, a social worker or a court. Supervised time sharing could only be temporary. A successfully reformed parent may pursue more time sharing in the future.
