Detective agencies and private investigators carry out enquiries for individuals, businesses and professional clients. Their work may include locating missing people or tracing debtors, checking identities and addresses, researching personal or business backgrounds, and making discreet enquiries into suspected fraud, theft, misconduct or relationship concerns. Some investigate insurance claims, workplace issues or commercial disputes, and may gather information for solicitors, insurers or employers. Services can involve interviews, public-record and online research, observation and surveillance, followed by a written report and supporting material such as photographs or video where appropriate. Investigators do not have police powers and must obtain and handle information lawfully, respecting privacy and data protection requirements. They cannot lawfully access private accounts, obtain protected records without authority or trespass to gather evidence.
