Can You Sue Someone for Hiring a Private Investigator
You cannot sue someone simply for hiring a licensed private investigator to observe you in public places, but you can sue both the hiring party and the investigator if the surveillance crosses into illegal conduct such as trespassing on private property, stalking, wiretapping, electronic GPS vehicle tracking without consent, or invasion of privacy.
Legal Surveillance vs Illegal Private Investigator Actions
Private investigators have no special police powers and are strictly subject to civil tort and criminal privacy laws.
| Surveillance Tactic | Legal Status | Potential Civil Lawsuit Cause of Action |
|---|---|---|
| Public Photography / Following on Public Roads | Legal (No expectation of privacy in public) | No valid lawsuit grounds |
| Peering Through Home Windows / Fenced Yard | Illegal (Trespass & Intrusion upon Seclusion) | Invasion of Privacy & Civil Trespass |
| Placing Hidden GPS Tracker on Vehicle | Illegal in most states without vehicle title ownership | Stalking & Electronic Surveillance Tort |
| Hacking Email / Tapping Phone Lines | Federal Felony (Wiretap Act & CFAA) | Federal Wiretap Violation & Punitive Damages |
How to Handle Suspected Illegal PI Surveillance in 4 Steps
Follow these protective steps if an investigator crosses legal boundaries.
Step 1: Document License Plates and Take Photographs from Safety
Record surveillance vehicle make, model, license plate numbers, and dates/times without confronting the operative.
Step 2: File an Official Police Harassment / Stalking Report
Contact local police to verify the investigator's state licensing and document any trespassing on your private property.
Step 3: Have a Mechanic Inspect Your Car for Hidden GPS Trackers
Have an automotive shop scan wheel wells and undercarriage for magnetic GPS tracking beacons.
Step 4: File for a Restraining Order and Civil Damages
Retain an attorney to file an injunction against harassment and seek monetary damages for intentional infliction of emotional distress.
Frequently Asked Questions (7 Questions Answered)
Q1: Is hiring a private investigator legal in a divorce or child custody case?
Yes. Hiring a licensed PI to gather evidence of infidelity, hidden assets, or cohabitation in public places is completely legal and widely utilized in family law litigation.
Q2: Can a private investigator follow you everywhere?
A PI can follow you in public areas (streets, restaurants, parks, stores) where no reasonable expectation of privacy exists, but cannot harass you, corner your vehicle, or follow you onto private property.
Q3: Can a private investigator tap your phone or read text messages?
No. Intercepting phone calls, reading private text messages, or hacking social media accounts without consent violates federal wiretap laws (18 U.S.C. § 2511) and state felony wiretapping statutes.
Q4: Is it legal for a PI to put a GPS tracker on your car?
In most states, a PI can only place a GPS tracker on a vehicle if the person hiring the PI is an owner on the vehicle title (e.g., a spouse whose name is on the car registration).
Q5: Can you sue for Intentional Infliction of Emotional Distress (IIED)?
Yes. If the investigator engages in outrageous, menacing behavior (e.g., following your children to school or intimidating you at night), you can sue for severe emotional distress.
Q6: Is the person who hired the PI legally liable for the PI's crimes?
Yes. Under civil agency and conspiracy law, the hiring party (such as an ex-spouse or employer) can be held vicariously liable for illegal acts committed by the investigator they directed.
Q7: Can a private investigator trespass on your private driveway?
No. Driveways marked with 'No Trespassing' signs or gated property boundaries are private property; an investigator cannot enter fenced curtilage without committing civil trespass.
