What we investigate.

  • Surveillance

    Mobile and stationary surveillance by a licensed investigator, with time-stamped video and a written log. Used for workers' comp claims, insurance fraud, custody matters, and partner or business-partner concerns.

    $85 to $150per hour
  • Workers' comp fraud

    When an injury claim does not match what you are hearing. We document the claimant's real activity level on video and deliver a report your carrier and defense attorney can use.

    $95 to $150per hour
  • Background checks and asset searches

    Criminal and civil records, employment and identity verification, business due diligence and asset location. Done within the Fair Credit Reporting Act when it is for hiring.

    $150 to $600flat rate
  • Infidelity and relationship matters

    If you need to know, we find out quietly and give you facts with dates, times and photos. No judgment, no drama, and no contact with the other person.

If this is personal.

Most people who call about a spouse, a custody matter or a missing relative have been carrying it for a while. You do not need to have it figured out before you call.

Tell us what you have noticed. We will tell you honestly whether an investigation is likely to answer your question, what it would cost, and what you could legally do with the result. If it is not worth your money, we will say so.

Nothing is shared with anyone without your written permission unless a court orders it. We can meet in person if that is easier than the phone.

Michael T.Licensed private investigator, PI 23720

Why evidence from us holds up.

Michael spent 15 years in patrol and investigations with the Chula Vista Police Department. Our investigators work to the same habits.

  • Chain of custody

    Every video file and photo is logged from the moment it is captured.

  • Reports written for a courtroom

    Factual, dated and objective. An attorney can hand them to a judge. Whether evidence is admitted is always the court's decision.

  • Legal methods only

    No trespass, no illegal recording, no pretexting for protected records. Evidence gathered illegally hurts your case.

  • Testimony if needed

    Our investigators will appear for deposition or trial.

  • A security license too

    If an investigation uncovers a real threat, the same firm can put a licensed guard in place under PPO 14929.

Common questions

Do private investigators need a license in California?

Yes. Private investigators must be licensed by the Bureau of Security and Investigative Services. MT Security & Investigations holds PI license 23720, which you can verify at search.dca.ca.gov.

Is what I tell you confidential?

Yes. We do not disclose clients, case details or findings without your written consent, except where a court order or the law requires it.

Is it legal to hire a PI to follow someone?

Surveillance in public places by a licensed investigator is legal in California. Trespassing, recording private conversations without consent, and placing a tracker on a vehicle you do not own are not. We work inside those limits.

Can your evidence be used in court?

Our reports and video are prepared to the standards used in California civil courts, and our investigators can testify. Admissibility is decided by the judge.

How long does a workers' comp investigation take?

Many are resolved with two to four days of surveillance spread over a couple of weeks. It depends on the claimant's routine.

Do you take cases outside San Diego County?

Yes. Field work is centered on San Diego County and nearby Southern California. Records research and skip tracing are nationwide.
