Hiring a private investigator is not something most people do every day. When you find yourself in a situation where you need one, the stakes are usually high — a relationship you're questioning, a fraud you suspect, a person you need to find. The last thing you need is to hand your case to someone unqualified.
Here is what you need to know before you hire a PI in Chicago or the surrounding suburbs.
Verify the License First — No Exceptions
In Illinois, private investigators are required to hold a valid state license issued by the Illinois Department of Financial and Professional Regulation (IDFPR). There is no gray area here. An unlicensed PI is operating illegally, and any evidence they collect may be inadmissible in court.
Before you agree to anything, ask for the investigator's license number and verify it yourself at the IDFPR website. A legitimate PI will give you that number without hesitation.
My Illinois PI license number is 115-002640. You can verify it any time.
Ask About Their Background — Not Just Their Title
Anyone can print a business card that says "Private Investigator." What matters is the experience behind the title.
Ask where they worked before going private. Ask what kinds of cases they have handled. Ask how many cases they have completed. A PI with a law enforcement background, military service, or specialized investigative training brings a fundamentally different skill set than someone who took an online course and got licensed.
I spent years as a Correctional Officer with the Cook County Sheriff's Department, served in the Illinois Army National Guard, and led cases through the National Special Investigations Unit. That background is not just a credential — it shapes how I approach every case.
Understand What You Are Paying For
Pricing in the PI industry is not always transparent. Some investigators quote a low hourly rate and then add fees for mileage, equipment, reports, and administrative time. By the time the invoice arrives, the number looks nothing like what you expected.
Ask these questions upfront:
- Is the hourly rate all-inclusive?
- Is there a minimum number of hours?
- What does the retainer cover?
- Will I receive a written report at the end?
My rate is $75 per hour, all-inclusive, with a four-hour minimum. No hidden fees. No surprise charges. You know exactly what you are paying before we start.
Make Sure They Will Handle Your Case Personally
Some PI firms take your case and hand it off to a subcontractor — someone you have never met, whose background you cannot verify, and who has no personal stake in your outcome.
Ask directly: "Will you personally be working my case?" If the answer is vague, that is a red flag.
I handle every case personally. No subcontractors. No hand-offs. When you hire me, you get me.
Confirm They Use Legal Investigative Methods
This one matters more than most people realize. Evidence gathered through illegal means — unauthorized wiretapping, trespassing, hacking — is not just inadmissible in court. It can expose you to legal liability.
A qualified PI knows exactly where the legal lines are and how to build a strong evidentiary case while staying well within them. Ask how they gather information. Ask whether their methods would hold up in court. If they are evasive, walk away.
Look for Specialization That Matches Your Case
A PI who primarily handles insurance fraud may not be the right fit for an infidelity investigation. A PI without digital forensics training is not equipped to trace cryptocurrency fraud.
Match the investigator's specialization to your situation:
- Infidelity or relationship concerns — Look for surveillance experience and discretion
- Fraud or financial deception — Look for forensic investigation credentials
- Background checks — Look for database access and verification experience
- Skip tracing — Look for experience locating individuals through legal data sources
I am a Certified Cryptocurrency Forensic Investigator and have handled cases across all five of these categories over more than 20 years.
Red Flags to Watch For
Before you sign anything, watch for these warning signs:
- No license number provided — Walk away immediately
- Guarantees a specific outcome — No ethical PI can promise results
- Asks you to pay entirely upfront — A reasonable retainer is standard; full prepayment is not
- Vague about methods — Legitimate investigators are transparent about how they work
- No written contract — Everything should be in writing before work begins
What to Expect After You Make Contact
A professional PI will start with a confidential consultation. This is your opportunity to explain the situation, ask questions, and determine whether the investigator is the right fit. You should never feel pressured to commit on the spot.
After the consultation, you will receive a clear outline of the proposed scope of work, the estimated cost, and a timeline. Once you agree and sign a contract, the investigation begins.
At the conclusion of the case, you receive a documented report — written, photographic, or video evidence depending on the nature of the investigation — that is legally obtained and suitable for use in court if needed.
The Bottom Line
Hiring a private investigator is a significant decision. Take the time to verify credentials, ask the right questions, and choose someone whose experience matches your situation.
