What Can a Private Investigator Legally Do in Texas?

The Texas Department of Public Safety (DPS) licenses and regulates private investigators under Chapter 1702 of the Texas Occupations Code. A licensed PI in Texas must pass a background check, complete required training, and maintain active licensure, which is renewed every two years.

Watson Private Investigation holds License A11319 and is a Travis County Approved Vendor, meaning our work meets the evidentiary standards required by Texas courts.

Conduct surveillance in public spaces: A PI can observe, photograph, and video record any person in a public location, streets, parking lots, restaurants, parks, without consent. Texas courts have consistently upheld that there is no reasonable expectation of privacy in public spaces.

Access public records: Court filings, property records, business registrations, vehicle registrations, and many government databases are public record. A licensed PI can legally access and compile this information.

Conduct background investigations: Using licensed data providers, a PI can compile comprehensive background reports including criminal history, civil judgments, address history, employment history, and asset searches.

Interview witnesses: A PI can legally approach and interview witnesses, neighbors, coworkers, and other parties, as long as they do not misrepresent their identity or use coercive tactics.

Serve legal process: Licensed PIs in Texas can serve subpoenas, summons, and other legal documents.

Trespass on private property: A PI cannot enter private property without permission: including fenced yards, private driveways, or buildings. Doing so constitutes criminal trespass under Texas Penal Code §30.05.

Intercept private communications: Recording phone calls, text messages, emails, or other private communications without the consent of at least one party is a federal crime under the Electronic Communications Privacy Act and a state crime under Texas Penal Code §16.02.

Impersonate law enforcement: A PI cannot claim to be a police officer, federal agent, or any other government official. This is a criminal offense under Texas Penal Code §37.11.

Access protected databases without authorization: Financial records, medical records, and certain government databases require legal process (subpoena) to access. A PI cannot access these through unauthorized means.

Stalk or harass a subject: Surveillance must be conducted within the bounds of Texas anti-stalking and harassment laws. A PI cannot follow someone into their home, place of worship, or other protected spaces.

Evidence gathered illegally is inadmissible in Texas courts, and worse, it can expose you and your attorney to civil liability.
