Once you've hired a private investigator, how you communicate with them directly affects the quality and efficiency of your investigation. Miscommunication wastes time and money. Clear, structured communication leads to better-targeted investigations and more useful results.

This 6-step guide covers best practices for working effectively with your PI from first contact through final report.

Step 1: Write Down Your Goals Before the Consultation

Before your first meeting with a PI, take time to write down exactly what you want to know. Not "I suspect my husband is cheating" — but "I want to know who he is meeting, where, and how often." Not "I need a background check" — but "I want to verify this person's employment history for the past five years and check for criminal records."

The more specific you are, the more focused and efficient the investigation becomes. Emotional distress can make it hard to think clearly in the moment — having written notes prevents you from forgetting key details.

Step 2: Set Measurable Objectives

What does success look like for your case? Define it before work begins. Examples:

  • "I want video documentation of my spouse at this specific location with another person."
  • "I want confirmation that this individual's claimed employment history is accurate or inaccurate."
  • "I want a current verified address for this person."

Measurable objectives help your PI know when they've achieved what you need — and help you evaluate whether the investigation was successful.

Step 3: Discuss Investigation Methods and Your Comfort Level

A professional PI will walk you through their proposed methods. Make sure you understand and are comfortable with what will be done on your behalf. Ask questions about surveillance techniques, GPS tracking (if applicable), database searches, and how evidence will be documented.

If anything makes you uncomfortable or seems legally questionable, say so. A reputable investigator will address your concerns directly and adjust the approach if needed.

Step 4: Establish Update Intervals

Before work begins, agree on how frequently you'll receive updates. Options include:

  • Daily written reports during active surveillance
  • Updates every 2–3 days
  • Weekly check-in calls
  • Updates only when significant findings occur

At Kanenson PI, we typically provide written daily updates during active surveillance phases. Consistent updates prevent the anxiety of wondering what's happening and keep you informed without disrupting the investigation.

Step 5: Communicate Clearly and Factually

When providing information to your PI or asking questions, stick to facts. Emotional framing — "I just know he's lying" or "She's definitely hiding something" — doesn't help the investigation. What does help: "He told me he was at work until 9pm on Tuesday and Thursday nights, but I noticed the car wasn't in the parking lot at 7pm."

Facts and observations, not interpretations and emotions, are what investigators need to work effectively. Keep your communication grounded in what you've actually observed.

Step 6: Schedule Check-Ins and Update Your PI When Circumstances Change

Investigations are dynamic. New information emerges. Subjects change their behavior. Your objectives may evolve. Regular scheduled check-ins allow you to share new information and adjust the investigation's focus as needed.

If something significant changes — your subject is leaving town, a key date is coming up, you received new information — communicate it to your PI immediately. Timing in investigations is often critical.

Additional Tips for a Successful Investigation

  • Keep notes of all interactions with your PI, including dates, what was discussed, and any commitments made.
  • Don't share case details with others. The more people who know about an investigation, the higher the risk of the subject being tipped off.
  • Trust the process. Investigations take time. Resist the urge to demand daily updates during periods when surveillance is strategic and patient — sometimes waiting is part of the work.
  • Be honest with your PI. Withholding information you think might be irrelevant can misdirect the investigation. Let your PI decide what's useful.
