What Information Can a Private Investigator Obtain?
Whether dealing with a contentious divorce, investigating suspected corporate fraud, vetting a potential business partner, or locating an estranged family member, individuals frequently ask: what information can a private investigator obtain? In popular movies and television thrillers, private eyes are routinely depicted hacking personal email accounts, tapping smartphone calls, tracking cell GPS coordinates, and obtaining confidential banking balances with a few keystrokes. In the real world, licensed private investigators (PIs) are bound by strict state and federal privacy statutes, including the Gramm-Leach-Bliley Act (GLBA), the Fair Credit Reporting Act (FCRA), and federal wiretapping laws. However, skilled licensed investigators possess access to proprietary commercial intelligence databases, public records repositories, and surveillance techniques that yield astonishingly comprehensive information.
Legally Accessible Intelligence: Public Records, Assets, and Surveillance
Licensed private investigators excel at uncovering publicly accessible yet obscure information across disparate jurisdictions. Utilizing specialized subscription databases restricted exclusively to licensed law enforcement and investigators (such as LexisNexis, CLEAR, and TLOxp), PIs can construct a comprehensive dossier in hours. They can locate verified current addresses, complete historical residential records, aliases, marriage and divorce decrees, and active civil litigation histories.
Furthermore, PIs conduct lawful asset investigations by identifying real property deeds, registered motor vehicles, corporate entity registrations, commercial aircraft or watercraft ownership, and county tax liens. In child custody and infidelity inquiries, investigators conduct physical surveillance in public places, capturing high-definition photographic and video evidence that is fully admissible in family court.
The table below outlines categories of information a licensed private investigator can legally obtain versus strictly prohibited data.
| Information Category | Legally Obtainable Information | Strictly Prohibited / Illegal Tactics | Governing Federal Privacy Statute |
|---|---|---|---|
| Real Estate & Asset Holdings | Deeds, mortgages, tax liens, registered luxury vehicles | Bank account balances, secret offshore accounts | Gramm-Leach-Bliley Act (GLBA) |
| Court & Legal History | Civil lawsuits, judgments, bankruptcies, criminal dockets | Sealed juvenile records, expunged criminal records | Freedom of Information Act (FOIA) |
| Physical Location & Habitation | Current residence, utility registrations, workplace verification | Trespassing on private curtilage, wiretapping homes | State Criminal Trespass Statutes |
| Communications & Tech | Public social media traces, open domain registrations | Hacking emails, reading text messages, phone wiretaps | Electronic Communications Privacy Act (ECPA) |
| Employment & Corporate | Business LLC registrations, corporate directorships | Personnel disciplinary files without court subpoena | Fair Credit Reporting Act (FCRA) |
A reputable investigator will never break federal privacy laws, ensuring all gathered evidence remains admissible in court.
Strict Legal Boundaries: Wiretapping, Bank Accounts, and Phone Records
The legal boundary line for private investigators is governed by federal statutes carrying severe criminal penalties. Under the Gramm-Leach-Bliley Act (GLBA), pretexting—impersonating an account holder or bank employee to obtain private banking account numbers or balance amounts—is a federal crime. While PIs can identify that a business or person owns real estate or corporate shares, they cannot legally tell you how many dollars are inside a personal checking account without a court subpoena.
Similarly, the Electronic Communications Privacy Act (ECPA) strictly criminalizes intercepting telephone calls, intercepting text messages, or installing unauthorized spyware keyloggers on computers. In public spaces, investigators have the legal right to photograph anything visible to the naked eye, but they cannot trespass into private backyards, aim directional microphones into private bedroom windows, or attach GPS trackers to vehicles without registered owner consent.
The table below reviews common investigative techniques and their admissibility in civil and family court proceedings.
| Investigative Technique | Permissible Legal Environment | Prohibited Environment / Boundary | Courtroom Admissibility Status |
|---|---|---|---|
| Public Video Surveillance | Public roadways, public parks, shopping centers | Inside private homes, fenced yards through blinds | 100% Admissible with investigator testimony |
| Vehicle GPS Tracking | Vehicle owned by client (e.g. spouse on title) | Vehicle owned solely by independent third party | Admissible if vehicle ownership rules are met |
| Social Media Intelligence (OSINT) | Publicly visible Facebook, Instagram, LinkedIn posts | Hacking passwords, catfishing with deceptive accounts | Fully Admissible with digital chain-of-custody |
| Trash Inspection (Dumpster Diving) | Garbage bags placed at public street curbside | Trash cans located inside private property gates | Admissible under California v. Greenwood precedent |
Adhering strictly to courtroom chain-of-custody standards ensures investigative reports carry decisive weight before judges.
How to Legally Hire and Direct a Private Investigator in 4 Steps
Follow this practical guide to retain an ethical, licensed private investigator and direct their casework safely.
Step 1: Confirm State Licensure and Professional Liability Insurance
Verify the investigator's active license number through your state licensing division (e.g., Department of Consumer Affairs or State Police).
Step 2: Sign a Formal Retainer Agreement Defining Case Scope
Execute a written contract outlining specific investigative objectives, hourly rates, retainer fee deposits, and strict adherence to legal tactics.
Step 3: Provide Objective Baseline Background Information
Supply verified full names, known aliases, dates of birth, vehicle descriptions, known addresses, and relevant photographs to focus the inquiry.
Step 4: Receive a Certified Investigative Report with Evidence Log
Obtain a formal written report documenting exact timestamps, surveillance logs, and date-stamped video evidence ready for courtroom submission.
Frequently Asked Questions (8 Questions Answered)
Q1: Can a private investigator get bank account balances?
No. Federal law (Gramm-Leach-Bliley Act) strictly prohibits obtaining bank balances or transaction histories without a formal court-issued subpoena.
Q2: Can a private investigator tap a phone or read text messages?
No. Wiretapping phone calls and hacking text messages violates federal law (ECPA) and carries felony criminal penalties. Evidence gathered this way is thrown out of court.
Q3: Can private investigators track someone's cell phone location?
No. Real-time cell phone ping tracking is restricted exclusively to law enforcement agencies with active judicial search warrants and cellular carrier cooperation.
Q4: Can a private investigator put a GPS tracker on someone's car?
Only if the client owns or co-owns the vehicle (such as a shared marital car). Placing a tracker on a vehicle owned solely by another person is illegal stalking in many states.
Q5: Can a private investigator run a criminal background check?
Yes. PIs have access to comprehensive state, county, and federal court databases to compile public criminal histories, warrants, and civil judgments.
Q6: Is surveillance footage from a private investigator admissible in court?
Yes. Video and photographic evidence recorded in public places by a licensed investigator is fully admissible in civil, family, and criminal court proceedings.
Q7: Can a private investigator find a hidden bank account?
While they cannot access balances, PIs can identify tangible assets like corporate entities, property, and vehicle holdings that point to undisclosed wealth in divorce.
Q8: How much does it cost to hire a private investigator?
Licensed investigators typically charge between $75 and $200 per hour, plus mileage and database fees, often requiring an upfront retainer of $1,500 to $3,000.
