The Maryland Petition for Emergency Evaluation is a legal document used to request an immediate mental health evaluation for a person who is an imminent danger to themselves or others. It can be submitted by a family member, law enforcement, or mental health professional. There are two types of Maryland Petition for Emergency Evaluation: an Emergency Petition for Evaluation and an Emergency Petition for Treatment. The Emergency Petition for Evaluation is used to request an immediate mental health evaluation to determine if an individual meets the criteria for involuntary commitment, while the Emergency Petition for Treatment is used to request an emergency admission to a mental health facility for treatment. Both petitions must be signed by the mental health professional or law enforcement who is making the request.
