Top Questions to Ask Before Hiring a Private Investigator

The Anh Luong • January 30, 2025

Hiring a private investigator is not a decision to take lightly. Whether you're dealing with a legal issue, personal concern, or business matter, finding the right investigator can make all the difference in uncovering the truth and protecting your interests. However, how do you know you're hiring someone trustworthy and skilled? It’s not always easy to tell just by looking at their website or reading reviews. That's why it’s essential to ask the right questions before bringing a private investigator on board.


As someone who’s been in the field for years, I’ve seen how asking the right questions can help you find the right professional for your needs. In this article, I’ll walk you through the top questions you should ask before hiring a private investigator, along with tips on what to look for in their answers. Let’s dive in!


What is Your Experience in This Area?


When hiring a private investigator, one of the first things to ask is about their experience. The world of private investigation is broad, and different types of cases require different skill sets. Are you looking for someone to help with a legal case, conduct a background check, or track down someone? The investigator you hire should have experience in the specific type of investigation you need.


Why it matters


Experience doesn’t just refer to how long someone has been in the business; it’s also about their familiarity with the specific issue you're facing. For instance, if you need someone to investigate a cheating spouse, a private investigator with a background in surveillance and infidelity cases would be ideal. If it’s a corporate fraud investigation, you want someone experienced in business-related cases.


What to listen for


Look for an investigator who can explain their background and give examples of similar cases they've worked on. A well-experienced investigator should be able to share stories (without breaching confidentiality) that demonstrate their capability to handle your specific needs.

What is Your Experience in This Area?

Are You Licensed and Insured?


Private investigation is a regulated profession in many places, including Australia. Hiring someone who is licensed and insured ensures that they are operating within the law and have the credentials to handle your case properly.


Why it matters:


A license shows that the investigator has met the legal requirements for the profession, such as passing exams and undergoing background checks. Insurance, on the other hand, protects you in case of mistakes or damages during the investigation process. If the investigator causes harm or loss of property while working on your case, insurance can help mitigate the financial impact.


What to listen for:


The investigator should easily provide proof of their license and insurance. They should be transparent about their qualifications and offer reassurance that they operate within the bounds of the law.


What Methods Will You Use to Investigate?


When it comes to investigations, methods matter. From surveillance to background checks to digital forensics, there are many ways an investigator can approach a case. It’s important to understand the methods your investigator plans to use and how they align with your goals.


Why it matters


The approach they choose can impact the results. For example, if you’re hiring an investigator for a surveillance job, you’ll want to make sure they’re skilled at discreet observation and tracking. If it’s a background check, ensure they have access to thorough databases and resources to uncover detailed information.


What to listen for


An experienced investigator should be able to outline the methods they’ll use in clear, understandable terms. Avoid anyone who is vague or reluctant to share their approach. They should be able to explain why those methods are the best fit for your case and how they will maximize the chance of success.

What Methods Will You Use to Investigate?

What Are Your Fees and How Do You Charge?


You don’t want any surprises when it comes to costs, so it’s crucial to get a clear breakdown of how the investigator charges. Some investigators work on a flat fee, while others bill by the hour or per task. Ask for a detailed estimate of costs upfront.


Why it matters?


Knowing the fee structure will help you avoid surprises down the road. It’s important to ask about any potential additional costs that could arise, such as travel expenses or fees for specialized services.


What to listen for?


A reputable investigator will be transparent about their fees and provide a clear estimate. They should also explain what their fees cover and how they calculate charges. Don’t hesitate to ask for a written contract that outlines the costs and services provided.


Can You Provide References or Case Studies?


A private investigator’s reputation is crucial, and you should feel comfortable asking for references or examples of their past work. A good investigator will have a portfolio of successful cases or satisfied clients to speak for their expertise.


Why it matters?


References and case studies give you insight into the investigator’s capabilities and reputation. If they’ve successfully handled cases similar to yours, that’s a good sign. It also shows that they’re confident in their work and have built a track record of success.


What to listen for?


Look for an investigator who provides references or at least outlines past cases with similar challenges to yours. Be wary if they seem hesitant to provide examples or references.

Provide References or Case Studies?

What Will the Investigation Process Look Like, and How Will You Keep Me Updated?


Understanding the process and communication plan is crucial. You want to know what to expect and how often you’ll be updated on the progress of your case.


Why it matters?


Clear communication helps you stay in the loop and ensures you're not left in the dark. Additionally, understanding the process gives you peace of mind that the investigator is organized and professional.


What to listen for?


The investigator should be able to explain the steps of the investigation in clear terms, from the initial consultation to the final report. They should also outline how often and by what means they’ll update you, whether it’s through emails, phone calls, or reports.


How Will You Handle Confidentiality?



Confidentiality is at the core of what private investigators do. You need to feel confident that any information shared with them will be kept secure.


Why it matters?


Sensitive information needs to remain protected. Whether it's about your personal life, business affairs, or legal situation, you don’t want it to be exposed to anyone who isn’t directly involved in the investigation.


What to listen for?


The investigator should discuss their approach to confidentiality and should be willing to sign a non-disclosure agreement (NDA) if needed. They should explain the measures they take to ensure that your information stays safe.

How Will You Handle Confidentiality?

What Is Your Success Rate or Track Record?


While past performance doesn’t guarantee future results, it does provide valuable insight into the investigator’s ability to handle cases effectively.


Why it matters


A high success rate or positive track record indicates that the investigator is skilled and reliable. It also shows that they know how to adapt their strategies to achieve favorable outcomes for clients.


What to listen for


An investigator should confidently share information about their track record without being boastful. They should be able to provide examples of success stories or testimonials from previous clients.
