In English law, an appropriate adult is a parent, guardian or social worker; or if no person matching this is available, any responsible person over 18. The term was introduced as part of the policing reforms in the Police and Criminal Evidence Act 1984 and applies in England and Wales.[1]
In England and Wales, an appropriate adult must be called by police whenever they detain or interview a child (under the age of 18[2]) or vulnerable adult. They must be present for a range of police processes, including interviews, intimate searches and identification procedures, as detailed in the Police and Criminal Evidence Act 1984 (PACE) Codes of Practice, primarily Code C.[3]
