What a Private Investigator Can and Can't Do in Texas

Television has ruined the private investigator. If you believe what you see on screen, a private investigator in Texas can hack into anyone's phone, tail a car through three counties without being noticed, and pull bank statements out of thin air — all before the commercial break.

Here's what a Texas PI can actually do, what they flat-out can't, and why the difference matters — especially if you're an attorney thinking about hiring one.

What a Texas Private Investigator Can Do

Surveillance — the Legal Kind

Real surveillance is patience, not drama. A licensed investigator can watch a subject from any place the public has a right to be: a parked car on a public street, a bench at the park, the booth across the restaurant. Photos and video shot from those spots, properly date-stamped, are legitimate evidence that holds up in a demand package or in front of a jury.

This is the workhorse of injury cases. A claimant says they can't lift more than five pounds — and then surveillance catches them hauling mulch at the garden center on a Saturday. That footage changes the entire value of a file. The defense is already running surveillance on claimants as a matter of routine. Having your own investigator in the mix means you're not only reacting to their video.

Find People Who Don't Want to Be Found

Witness locates and skip tracing are bread-and-butter PI work. It starts with professional databases and public records — last-known addresses, utility hooks, court filings, vehicle registrations — and ends with fieldwork, because a database gives you an address and a person gives you a person.

This one connects directly to our process-serving side. When a defendant vanishes right after a demand letter goes out, a locate feeds the serve: find them, then get papers in their hand.

Document a Scene Before It Changes

Crash scenes get repaved. Skid marks fade. Store security footage gets overwritten — sometimes in 30 days, sometimes in 7. Scene documentation is photos, measurements, and sketches taken early, while the evidence still looks like it did the day it mattered.

It's one of the cheapest forms of case insurance there is. We've seen files where a single set of early scene photos moved settlement talks more than months of medical records did.

Dig Through Public Records

Background research, asset research, document retrieval. Court records, property records, business filings, liens — if it's public, a PI can pull it, organize it, and put it in a report you can actually use.

This is the quiet work nobody brags about: whether there's money behind the policy limits before you sink a year into a file, or whether the other side's star expert has a credibility problem.

Take Recorded Witness Statements

A good investigator can get a witness talking when a letter and a phone call couldn't. Texas is a one-party consent state, which means an investigator who's part of the conversation can record it legally. Done right, you get a recorded statement with a transcript — usable, organized, and ready for the file.

What a Texas Private Investigator Can't Do

This is the part TV gets wrong, and it's the part that matters most — because evidence gathered illegally doesn't just get thrown out. It can blow back on the attorney who hired the investigator.

They Can't Hack Into Anything

No breaking into email accounts. No cracking phones. No installing spyware, no "social engineering" a password reset out of a help desk. That's a crime under federal law and Texas law alike, and anything pulled that way is poison — inadmissible and a liability factory.

If a PI tells you they can get into someone's accounts, that's your sign to hire a different PI.

They Can't Put a GPS Tracker on Someone Else's Car

Planting a tracking device on a vehicle you don't own — without the owner's consent or a court order — crosses the line in Texas. (The U.S. Supreme Court ruled in United States v. Jones (2012) that sticking a GPS unit on a car is a search.) Private investigators don't get a wider lane than the police here. Mobile surveillance from public roads is legal. A tracker on the bumper is not.

They Can't Trespass — or Pretend to Be a Cop

No climbing fences, no picking locks, no "borrowing" a maintenance uniform to get past a gate. And no flashing anything that looks like a badge. Impersonating a peace officer is a crime in Texas, full stop. A legitimate investigator gets the shot from public ground or doesn't get the shot.

They Can't Pull Bank or Medical Records on a Whim

Financial and medical records are protected. A PI can't sweet-talk a bank teller into handing over statements or call a clinic pretending to be the patient. Those records require the subject's authorization or a subpoena — same as they'd require for you.

They Can't Operate Without a License

Texas requires private investigators to be licensed under the state Occupations Code, regulated through DPS. That's the floor, not the ceiling — but it's non-negotiable. An unlicensed investigator's work product carries an evidence problem from day one, and hiring one means you're paying someone who's breaking the law while working your case. Always verify the license.

Why the Legal Lines Matter to Your Case

Here's the practical version for attorneys: illegally obtained evidence doesn't help you — it hands the other side a motion and hands you a headache. When you retain an investigator, ask how the evidence will be obtained, not just what it'll show. Get it in a written report with timestamps, photos, and video. Ask about chain of custody. If the investigator gets vague about methods, walk away.x

The good ones won't be vague. A straight investigator will tell you what they can get, what they can't, and when the juice isn't worth the squeeze — and that honesty is worth more than any single piece of footage.

When to Bring One In

Early. Evidence degrades, witnesses move, footage gets overwritten, and scenes change. If you're weighing whether a file needs investigative work, that's usually the file that does. Our process serving services and Texas investigation work run side by side for a reason — locates feed serves, serves feed cases, and cases move when the facts are nailed down early.
