How to Find a Private Investigator

Finding a private investigator (PI) can feel overwhelming. But with the right steps, you can hire someone to help. Here’s how to get started.


Research Options

Search online for PIs in your area. Use sites like Google or Yelp. Check the Better Business Bureau for ratings.


Ask for recommendations. Lawyers or friends may know reliable investigators. Professional groups like the National Association of Legal Investigators (NALI) and the Professional Association of Wisconsin Licensed Investigators (PAWLI) are good resources.


Verify Credentials

Make sure the PI is licensed. Licensing rules vary by state. Check your state’s licensing board.


Some PIs have certifications, such as:

  • Certified Professional Investigator (CPI)

  • Certified Fraud Examiner (CFE)Certifications show extra training but aren’t required.


Look for liability insurance. It protects both you and the investigator.


Check for complaints or disciplinary actions. Verify their license is active.


Check Experience

Ask how long the PI has been working. Find out if they’ve handled cases like yours.

Some PIs specialize, while others work on a variety of cases. Ask for examples of past work, but understand they may not share sensitive details.


Discuss their tools and methods. Do they use tracking devices or forensic software? Experienced PIs often rely on advanced tools.


Ask about their success rate. While no PI can guarantee results, a strong track record can give you confidence.


Review References and Reviews

Ask the PI for references. Contact previous clients and ask questions like:

  • Did the PI deliver results?

  • Were they professional?

  • Would you hire them again?


Read online reviews. Look for patterns, such as complaints about communication. Be cautious of overly generic reviews.


If something concerns you, ask the PI directly. A good investigator should address your questions openly.


Ask About Methods

Learn how the PI plans to approach your case. Ethical investigators follow the law. Avoid anyone suggesting trespassing or hacking.


Ask about their use of technology. Tools like GPS trackers or drones can speed up investigations, but they must comply with the law.


Confirm how they protect your data. If personal details are involved, ensure they use secure systems.


If the PI works with a team, ask how tasks are divided. This ensures thorough work.


Discuss Costs

PIs charge differently based on the work. Common pricing includes:

  • Hourly rates, usually $100–$200 per hour

  • Flat fees for tasks like background checks

  • Retainers for larger cases


Request a written estimate. Ask about additional costs like travel or database fees.

The cheapest PI isn’t always the best. Compare cost with their experience and tools.


Meet in Person

Meet the PI before hiring them. This helps you judge their professionalism. Ask questions like:

  • How will you update me?

  • What’s the timeline?

  • Have you handled similar cases?


Observe their demeanor. A good PI should be clear and calm.


Review the Contract

Before work begins, read the contract carefully. It should outline:

  • Scope of work

  • Costs

  • Confidentiality terms

  • Timelines


Make sure the contract includes a confidentiality clause. Protect your privacy and clarify ownership of findings.


Keep Communication Open

Once hired, stay in touch with the PI. Share details they need. Discuss how often you want updates. Regular communication helps keep the investigation on track.


Evaluate Results

At the end, review the findings. Did they meet your expectations? If satisfied, leave a review.

If the results fall short, ask why. Some cases may not go as planned, but a professional PI will explain their actions and limitations.



Finding a private investigator takes effort, but it’s worth it. Research carefully and ask the right questions. With the right PI, you can find the answers you need and move forward.
