Missouri private investigators operate under a state licensing framework that defines what they can and cannot do. Understanding those boundaries is important whether you're hiring a PI or just curious about what the profession involves.
What a Licensed Missouri PI Can Do
Surveillance in Public Spaces
A licensed PI can observe and document the activities of any person in any location where the public has lawful access. Parking lots, streets, parks, restaurants, and other public settings are fair game. Photographs, video, and audio recordings made in public — where there is no reasonable expectation of privacy — are generally lawful and admissible.
Open-Source Research
Investigators can legally compile any information that is publicly available: court records, social media posts, property records, business filings, news articles, and other publicly accessible sources. People often share more information publicly than they realize.
Licensed Database Searches
Licensed PI agencies have access to investigative databases not available to the general public — utility records, address history, vehicle registrations, and more. These searches are conducted under the terms of those database agreements, which restrict their use to lawful investigative purposes.
Interviews and Canvassing
PIs can speak with witnesses, neighbors, coworkers, and other individuals who may have relevant knowledge — as long as those conversations are voluntary and conducted without misrepresentation.
Skip Tracing and Locate Services
Locating individuals through database searches, public records, and investigative methods is a core PI function. There is no law preventing a licensed investigator from legally finding where someone lives or works.
What a Missouri PI Cannot Do
- Enter private property without consent — no trespassing to conduct surveillance, even for a legitimate case
- Record conversations without consent — Missouri is a one-party consent state for audio recordings, but recording in a private setting where the PI is not a party to the conversation is prohibited
- Access private records without legal process — bank records, medical records, and tax returns require a subpoena or court order
- Impersonate law enforcement or government officials — this is a criminal offense
- Conduct illegal pretexting — obtaining information through fraudulent misrepresentation of identity is prohibited
- Hack into electronic accounts or devices — computer fraud laws apply to investigators the same as everyone else
Missouri PI Agency Licensing
Missouri requires PI agencies to hold a state license — Faithful Path Investigations holds Agency License #2025036830 issued by the Missouri Department of Public Safety. When hiring any PI, verify current licensure through the Missouri Division of Professional Registration.

Frequently Asked Questions
- Can a PI access my phone records?
- No. Phone records are protected under federal law and cannot be obtained without a court-issued subpoena. Any PI claiming to be able to obtain private phone records without legal process is either misrepresenting their capabilities or operating illegally.
- Can a PI conduct surveillance on my property without my knowledge?
- A PI can observe your property from public spaces without your knowledge. A PI cannot enter your private property to conduct surveillance. Security cameras covering areas visible from public spaces may capture information that is lawfully used.
