How to Easily Find Out Who Hired a Private Investigator on You (2024)

You have a sneaking suspicion that someone may have hired a private investigator to look into your personal life, business dealings, or other private matters. While people hire PIs for many legitimate reasons, having your privacy invaded can feel like a violation. If you want to find out who hired the PI and why, there are steps you can take to get answers. Here is an overview of how to identify it and what you can do.


1. Look for Red Flags

The first signs that a private investigator (PI) may be looking into your affairs are often subtle and circumstantial. Pay close attention to any behaviors or events that seem suspicious or raise red flags. Some common signs to watch out for include:

  • Unfamiliar vehicles parked near your home or office for extended periods of time. Skilled PIs often use discreet methods of surveillance, but their presence can still be detected. Take note of any cars you don’t recognize that seem to be stationed near your locations.
  • Odd background noises, clicks, or echoes on phone calls. Experienced PIs sometimes monitor and track targets by tapping phone lines. Unusual interference on calls may indicate wiretapping.
  • Being asked probing personal questions by strangers. If someone you don’t know starts trying to get sensitive details about you, your job, relationships etc., they may have been hired by an investigator. Don’t answer intrusive questions from unfamiliar people.
  • Legal documents or proceedings referencing private details you haven’t disclosed. If a lawsuit, subpoena, or other official process reveals deeply personal data that only dedicated digging could uncover, it suggests a PI has been empowered to access that information.
  • Electronic devices or accounts exhibiting signs of hacking or spyware installation. Unexpected pop-ups, changed settings, or activity logging into accounts you didn’t authorize could mean a PI has compromised your digital footprint to gather intel.
  • Sensitive documents have disappeared from your home, office, car etc. A common PI tactic is stealing materials to copy or photograph. Noticing missing files, records, etc. points to possible PI infiltration.


If any of these occurrences make you suspect, don’t dismiss it. Plenty of illegal or unethical PI work does happen, despite regulations.


2. Think About Who Would Have a Motive

Once you suspect a private investigator may be looking into your life, think carefully about who would have a motive to hire one. Make a list of individuals who may have an incentive or desire to probe into your personal affairs, business dealings, finances, or other sensitive matters. Some common categories to consider include:

  • Estranged or former romantic partners, especially those with ongoing conflicts, grudges, or custody/divorce disputes. It is very common for suspicious or adversarial separated spouses to hire PIs to gain leverage.
  • Rival business owners, partners, or competitors who may want access to your trade secrets, strategies, or other proprietary information. Corporate espionage using PIs is frequent in the business realm.
  • Overbearing, controlling, or protective family members who want to closely monitor your activities, relationships, or communications without your knowledge.
  • Law enforcement agents or government regulators who may be conducting undercover investigations without fully disclosing their monitoring activities.
  • Lenders or creditors who want to thoroughly vet your finances, assets, employment status and creditworthiness before approving loans.
  • Aggressive journalists or media outlets digging for gossip or trying to flesh out your background for a salacious story.


Making a list of those with possible motives helps narrow down the search for who is most likely responsible for hiring a PI, if you are being monitored. However, you want to avoid making unfair accusations, so only focus suspicion on those with legitimate incentives and reasonable cause to investigate you. Keep the list of suspects confined to those who would realistically take such invasive action based on your circumstances and history together.


3. Check for Familiar PI Tactics

Once you suspect a private investigator is on your trail, be on the lookout for familiar tactics they often employ. Watch for these common PI investigative techniques:

  • Emails or phone calls trying to trick you into revealing personal data, bank info, passwords, etc. This is known as “pretexting” – investigators use deception and manipulation to gather intel.
  • Your curbside trash cans are emptied but then returned with contents precisely put back. PIs regularly rifled through discarded mail and documents seeking clues about finances, contacts, habits.
  • Official or vague looking letters start arriving for you from ambiguous companies. These “phony fronts” are set up by PIs to have a neutral paper trail.
  • Liens, ownership records, or court documents tied to your property/assets start listing investigator aliases or front companies as stakeholders. They insert themselves as creditors.
  • You are tipped off anonymously by an informant or whistleblower at a PI firm uncomfortable with an unethical job involving you. Some will rat out illicit cases.
  • Searching PI licensing databases shows your name as a subject of interest for a recent or open investigation. Some have public lookup options you can use.


Spotting such standard industry tricks in action around your life strongly suggests professional PIs are being employed to monitor and probe. Their playbook of familiar tactics gives them away if you know what to look for. Be vigilant for signs of their skulduggery.


4. Consult a Private Investigator Yourself

Consider fighting fire with fire. Hire your own licensed professional PI through a reputable firm to uncover whether, how, and by whom exactly you are being scrutinized.

A competent PI has insider expertise in all the tricks of the trade, making them adept at identifying and tracing the steps of any other operatives hired to pry into your affairs. They can spot reporting methods, surveillance trails, document copying, communication monitoring and other hallmarks of investigator handiwork.

A good PI can also run surveillance detection sweeps to check your home, office, vehicles and electronic devices for any hidden cameras, bugs, tracking equipment or spyware planted by invasive investigators. Just be sure to choose a legitimate, licensed PI firm with solid references that follows all professional and ethical regulations.

When meeting to discuss retaining their services, do so in person rather than strictly online. Always verify their PI license, seek multiple references, examine reviews, and get a written service contract detailing fees and exactly what services will be provided. Make sure to vet a PI thoroughly on the front end before hiring them to start probing into your suspected monitoring.


5. Set Traps to Flush Out Who’s Watching You

If hiring your own private investigator is not feasible, you can still take proactive measures to flush out who exactly is monitoring you. Carefully set traps designed to force the hand of the hidden PI and identify who has employed them. Some ideas include:

  • Strategically feeding false information during both in-person and phone conversations with specific contacts. Wait and watch to see if that fictitious info gets back to you, revealing who heard it and is funneling your data.
  • Leaving mock sensitive documents, objects, emails, or records somewhere a PI could access them. If they disappear, it may implicate who wanted the bogus intel.
  • Having staged conversations within potential physical or digital surveillance range, purposely mentioning made-up details about your finances, plans, contacts, etc. If they get echoed back later, it’s clear someone is eavesdropping.
  • Suddenly altering routines, behaviors, appointments, travels etc. Any reactions or disruptions to the changes could indicate a PI or team is closely tracking your patterns.


Essentially, you turn the tables and trick the PI into gathering and reporting nonsense data. When that junk info makes its way to you secondhand, you can deduce who saw it via the investigator’s surveillance, pinpointing who likely hired them. Just take care to remain ethical while laying traps – don’t fabricate extremely damaging lies.


6. Check Financial Records for Payments

Another way to identify if and who retained an investigator is by searching records for telltale payments:

  • Subpoena and audit your suspect’s bank accounts and credit card statements. Large PI agency fees may appear.
  • Ask PI firms you suspect directly if they received payments connected to you, either under your name or a cover one. Some will check records as a courtesy if asked.
  • File open records requests for your suspects’ government expenditures. Public agencies usually need transparent PI hiring practices.
  • Look for checks to fake businesses that sound like PI fronts. ‘Research Associates’, ‘Information Services’, etc.
  • Cross reference dates when you first felt investigated with payments in their records. The timing could link it to hiring a PI.


Verification of financials covering when you were probed can reveal who funded it, even if under a different name.


7. Confront Them and Demand Answers

Once you gather evidence pointing to who is responsible, you can approach them directly. Of course, take care with any accusations and focus on facts. Avoid sounding paranoid or making emotional arguments.

Calmly outline the proof that makes you believe they hired an investigator against you. Gauge their reaction – do they fess up and apologize? Or deny it and act indignant themselves?

You can negotiate to settle the matter amicably. Try asking:

  • Why did you feel the need to investigate me in secret?
  • What were you trying to find out?
  • How did the PI operate – did they conduct surveillance, access my accounts, etc?
  • Will you agree to stop the investigation?
  • Are you willing to destroy or anonymize any data collected about me and not use it further?
  • Do you accept that this violated my privacy and autonomy? Will you apologize?


A reasonable, ethical person may own up to their actions and make amends. If they become hostile or continue lying about invading your privacy, you may need to take legal action.


8. Consult a Lawyer About Your Options

If you believe an unscrupulous private investigator’s invasive actions put your safety, finances, reputation, or other interests at serious risk of harm, consult with a qualified lawyer to discuss your potential legal options and recourse. Depending on the specifics of your situation, you may have grounds to pursue legal action if the PI committed:

  • Tortious invasion of privacy – The investigator deliberately and harmfully intruded upon your reasonable expectation of solitude, seclusion, or your private affairs.
  • Intentional infliction of emotional distress – The PI’s extreme, outrageous, or deliberately abusive conduct caused you severe mental suffering or anguish.
  • Defamation – The PI spread and published false, malicious statements about you that damaged your reputation or livelihood.
  • Misappropriation of trade secrets – Your confidential, proprietary business data or intellectual property was stolen and exploited.
  • Trespassing – The investigator physically entered or infiltrated your private property or secure locations without consent.
  • Stalking or harassment – You were subjected to repetitive unwanted surveillance, intrusion, or communication that caused reasonable fear.


A qualified attorney can provide guidance on whether you have sufficient grounds to pursue legal action against the client who hired the problematic PI, the investigator or agency itself, or both. They can also draft formal cease and desist orders. Prayerfully weigh the risks, costs and benefits prior to initiating any litigation.


9. File a Complaint With Regulators

If the PI obtained information about you illegally or violated codes of ethics, report them to oversight bodies:


The investigators risk losing their license, membership, or ranked reputation if your complaint shows misconduct toward you as a subject. This provides motivation to make things right if they don’t want censure.


10. Take Countermeasures to Prevent Further Intrusion

After exposing who hired the PI and taking available actions, take precautions to avoid continuing victimization:

  • Install home security like cameras, alarms, and motion sensor lights to deter physical surveillance.
  • Use encrypted communication tools and enable two-factor authentication for accounts to block electronic spying.
  • Periodically search your name online and use Google Alerts to monitor anyone mentioning you publicly.
  • Switch up your daily movements and habits to make tracking more difficult.
  • Share only essential personal information with even close friends or colleagues in case it gets back to the PI through inquiry.
  • Retain a lawyer on standby and immediately document any suspected repeat intrusions. Having early evidence will aid pursuing formal restraining orders if the PI persists.


With vigilance and the help of professionals, you can identify problematic investigators and prevent further privacy erosion. Don’t ignore warning signs that someone hired a PI against your wishes – take action to protect yourself.


What are some signs my devices may be compromised by a private investigator?
Unusual activity in online accounts, pop ups for spyware downloads, microphones or cameras turning on unexpectedly could indicate monitoring software installed by a PI.
You may need to identify who hired them first since PI’s have defenses around just doing their job for a client.
Potentially medical privacy laws, financial fraud, or theft of trade secrets if they accessed extremely sensitive confidential data.
You usually need to prove unreasonable harassment first, not just discomfort with their surveillance.
Don’t panic. Get evidence of them making illegal extortion-type demands, then go to the police.
