How to Hire a Private Investigator
Hiring a private investigator is not a decision most people make more than once. For many clients — whether they are attorneys preparing for litigation, business owners investigating internal fraud, or individuals navigating a difficult personal situation — it is an unfamiliar process in a high-stakes moment.
This guide is designed to help Dallas–Fort Worth residents and businesses understand what to look for when hiring a licensed private investigator in Texas, what questions to ask, and how to protect yourself throughout the process.
1. Verify Licensing Before Anything Else
In Texas, private investigators are required to hold a license issued by the Texas Department of Public Safety (DPS) under the Texas Occupations Code, Chapter 1702. This is not optional — operating as a PI without a license is a criminal offense in Texas.
Before hiring any investigator, ask for their license number and verify it directly through the Texas DPS online license verification portal. A reputable firm will provide this information without hesitation.
At Dark Harbor Private Investigations, all investigators hold active Texas PI licenses and are in full compliance with Chapter 1702. License information is available upon request.
2. Confirm Professional Liability Insurance
A licensed PI firm should carry professional liability insurance (also called errors and omissions insurance) as well as general liability coverage. This protects you as the client in the event of a mistake or dispute.
Ask for a certificate of insurance. If a firm cannot produce one, that is a significant red flag.
3. Understand What a PI Can and Cannot Do Legally
Texas law places clear boundaries on what private investigators may do. Understanding these boundaries helps you set realistic expectations and protects you from engaging a firm that operates outside the law.
- PIs can conduct surveillance in public places, perform background research using public records, locate individuals using legal methods, and document activities that occur in plain view.
- PIs cannot access private communications without consent, trespass on private property, impersonate law enforcement, access protected databases without authorization, or engage in activities that constitute stalking or harassment.
- Any firm that promises to obtain information through illegal means should be avoided — and reported.
4. Ask About Documentation Standards
If your matter has any legal dimension — a custody dispute, litigation, insurance claim, or corporate fraud investigation — the quality of documentation matters enormously. Evidence gathered improperly or documented carelessly may be inadmissible or challenged in court.
Ask specifically how the firm prepares its reports, whether investigators are available for sworn testimony, and whether the firm has experience with cases that have proceeded to litigation.
5. Evaluate Communication and Confidentiality Practices
A professional PI firm should be able to articulate clearly how it protects client information, who has access to case files, and how it communicates with clients throughout an engagement. Vague answers to these questions are a warning sign.
Dark Harbor operates under formal confidentiality protocols. Client information is accessible only to investigators directly assigned to the matter, and all communications can be handled through secure channels upon request.
6. Be Wary of Guarantees
No legitimate private investigator can guarantee specific outcomes. The results of any investigation depend on facts, circumstances, and factors outside the investigator's control. A firm that promises to "find what you're looking for" or guarantees specific results is either being dishonest or setting you up for disappointment.
What a good firm can promise is diligence, professionalism, and an honest assessment of what is achievable — before the engagement begins.
7. Understand Pricing Before You Commit
Reputable PI firms typically charge on an hourly basis, with expenses billed separately. Most engagements begin with a retainer. Be cautious of firms that offer unusually low flat rates — investigative work requires time, skill, and resources, and pricing that seems too good to be true often reflects the quality of the work.
Ask for a written scope of work and fee estimate before signing any agreement. A professional firm will provide this as a matter of course.
8. Look for Relevant Experience
Not all PI firms are equally equipped for all case types. A firm with deep experience in corporate fraud investigations may not be the best choice for a domestic matter, and vice versa. Ask specifically about the firm's experience with cases similar to yours.
