Elder abuse is generally investigated by ​​Adult Protective Services. A case worker will begin by asking the older adult or a legal guardian permission to investigate. (If permission is denied but there is evidence that someone is at risk of being harmed, a case worker may get a court order or involve the police.) After collecting proof of abuse, action may be taken to remove the perpetrator or move the elderly person to a safer setting. In cases of financial, physical, or sexual abuse, criminal charges may also be laid.
