How to Hire a Private Investigator: What You Need to Know

Hiring a private investigator can help individuals, attorneys, and businesses obtain reliable information when important questions remain unanswered. TJS Private Investigations explains how to choose a qualified investigator, verify licensing, understand investigative costs, and know what to expect from professional investigative services.

When people begin searching for a private investigator, they are often facing a situation that has become difficult to resolve on their own.

A spouse's unexplained activities may raise questions. An attorney may need to locate a witness. A business owner may suspect employee misconduct. A family may be searching for someone who has disappeared from contact.

Although these situations differ, they share an important consideration: obtaining reliable information requires more than simply finding someone willing to investigate.

Hiring a private investigator means selecting a professional who understands how to develop information, conduct lawful investigations, document findings, and communicate results responsibly.

At TJS Private Investigations, our perspective is that clients should understand the investigative process before committing their time, resources, and trust.

This guide explains how to hire a private investigator, what qualifications to look for, which questions to ask, how investigative fees work, and what separates professional investigative services from unreliable promises.

1. Determine Why You Need a Private Investigator

Before contacting an investigative agency, identify the specific question you need answered.

Some individuals begin with a general concern, such as believing that someone is hiding information. Others have a defined objective, such as locating a witness, documenting activities, or obtaining information relevant to litigation.

The clearer the objective, the easier it becomes to evaluate whether an investigation is appropriate.

Common reasons people hire private investigators include:

• Suspected infidelity or unexplained activities.

• Missing persons and locate investigations.

• Child custody and family-related concerns.

• Surveillance and activity documentation.

• Background investigations.

• Witness location and litigation support.

• Employee misconduct and corporate fraud concerns.

• Estate, heir, and beneficiary searches.

Not every situation requires the same investigative approach.

For example, locating an individual may involve lawful records research and information verification, while documenting activities may require physical surveillance.

What we recommend: Before contacting an investigator, write down the central question you want answered, the information you already possess, and how you intend to use the findings.

This helps establish an appropriate investigative objective without unnecessarily expanding the scope of the assignment.

2. Verify That the Private Investigator Is Properly Licensed

One of the first steps in hiring a private investigator is verifying the professional's licensing status.

In Texas, private investigative services are regulated under Texas Occupations Code Chapter 1702 through the Texas Department of Public Safety's Private Security Program.

Clients should confirm that the investigative company holds the licensing required for the services being offered.

Licensing requirements vary by jurisdiction, so individuals hiring investigators outside Texas should consult the appropriate regulatory authority.

Why Licensing Matters

Licensing provides a regulatory framework for professional investigative activity.

However, a license does not grant unrestricted authority to obtain private information, enter property, intercept communications, or conduct otherwise unlawful surveillance.

A properly licensed investigator must still comply with applicable privacy, recording, trespassing, and other legal restrictions.

How to Verify an Investigator in Texas

The Texas Department of Public Safety provides information about private security regulation and licensing.

Prospective clients can use the department's official resources to verify relevant licensing information.

We recommend checking credentials independently rather than relying exclusively on claims made in advertising or promotional materials.

3. Look for Experience Relevant to Your Investigation

Private investigation is not a single, uniform specialty.

An investigator who primarily conducts insurance surveillance may have a different professional background from someone who specializes in witness location, corporate investigations, or family-related matters.

When evaluating an investigative agency, consider whether its experience and capabilities align with your particular needs.

Ask About Investigative Methods

A professional investigator should be able to explain, in general terms, how an assignment might be approached.

For example, surveillance may require advance planning, suitable observation locations, careful documentation, and an understanding of the subject's likely activities.

A locate investigation may involve reviewing available identifying information, examining legally accessible records, and verifying potential leads.

Clients do not need to understand every technical aspect of investigative work. They should, however, receive a reasonable explanation of the proposed approach and its limitations.

Evaluate Professional Judgment

Experience should be reflected in how an investigator evaluates a situation, not simply in the number of years advertised.

Does the investigator ask relevant questions?

Are the proposed methods appropriate to the objective?

Does the investigator acknowledge uncertainty?

Are legal and ethical limitations discussed?

From our investigative perspective, these considerations are essential when assessing professional competence.

4. Understand What a Private Investigator Can and Cannot Legally Do

A common misconception is that private investigators have access to the same information and authority as law enforcement.

They do not.

Private investigators may conduct lawful research, surveillance, interviews, and other investigative activities within applicable legal boundaries.

However, holding an investigative license does not authorize unrestricted access to confidential records or private communications.

An investigator generally cannot obtain protected medical records, access private email accounts, hack electronic devices, or retrieve confidential banking information without appropriate legal authorization.

Likewise, GPS tracking, audio recording, surveillance, and access to private property may be subject to significant legal restrictions.

What we recommend: Be cautious of anyone who promises access to confidential information without explaining the legal basis for obtaining it.

A professional investigator should be willing to discuss the lawful scope of an assignment and decline requests that would require improper methods.

5. Ask the Right Questions Before Hiring an Investigator

The initial consultation provides an opportunity to evaluate the investigative agency and determine whether its services align with your needs.

Consider asking the following questions:

1. Is your investigative company properly licensed?

2. Do you handle investigations similar to mine?

3. What investigative methods may be appropriate?

4. What information do you need from me?

5. How are investigative fees calculated?

6. Will I receive a written report or other documentation?

7. How will you communicate progress and findings?

8. What circumstances could limit the investigation?

9. How is sensitive client information protected?

10. What should I realistically expect from the assignment?

The purpose of these questions is not to demand guarantees.

It is to determine whether the investigator communicates clearly, understands the objective, and approaches the assignment professionally.

An agency that explains uncertainty and limitations may provide a more realistic assessment than one that promises immediate answers.

6. Understand How Much a Private Investigator Costs

Private investigator fees depend on the nature, complexity, duration, and resources required for the assignment.

Some investigative services may involve research and verification. Others require field surveillance, travel, specialized planning, or multiple investigators.

Common billing arrangements may include hourly fees, retainers, minimum assignment periods, or agreed project-based charges.

Factors That Influence Investigative Costs

Several considerations may affect pricing:

• Type and complexity of the investigation.

• Number of investigative hours required.

• Travel distance and geographic coverage.

• Number of investigators assigned.

• Availability and accuracy of starting information.

• Research and documentation requirements.

• Reporting and additional authorized expenses.

Actual pricing should be discussed with the investigative agency before work begins.

Why the Lowest Price Is Not Always the Best Value

A low advertised rate does not necessarily reflect the total cost or quality of an investigation.

Clients should consider the proposed methodology, experience relevant to the assignment, documentation standards, billing transparency, and likelihood that the planned work will address the investigative objective.

Our recommendation is to evaluate investigative value rather than hourly cost alone.

The goal should be to obtain useful, reliable information through a reasonable and professionally managed investigative process.

7. Know What Information to Provide Your Investigator

The quality of the information available at the beginning of an investigation can influence planning and efficiency.

Depending on the assignment, useful starting details may include:

• Correct names and known aliases.

• Relevant dates and locations.

• Vehicle descriptions.

• Known schedules or patterns.

• Previous addresses or contact information.

• Relevant documents or communications lawfully in the client's possession.

• A clear explanation of the investigative objective.

Information should be accurate and obtained lawfully.

Clients should avoid providing material accessed through unauthorized accounts, unlawful recordings, or other improper methods.

An investigator may need to verify the information independently before relying on it.

8. Understand What Happens After Hiring a Private Investigator

Although investigative procedures vary, professional assignments generally involve several important stages.

Case Assessment

The investigator reviews the available information, identifies the objective, and evaluates potential methods and limitations.

Investigative Planning

An appropriate strategy is developed based on the assignment's circumstances, resources, and legal requirements.

Investigation and Documentation

The investigator conducts authorized investigative activities and documents relevant findings.

Communication and Reporting

The client receives information according to the agreed reporting arrangements.

A report may include observations, verified information, investigative findings, and limitations affecting interpretation.

Review of Findings

The client evaluates the information and determines whether additional investigative work, legal consultation, or another course of action is appropriate.

Not every investigation results in a definitive answer.

The investigator's responsibility is to communicate the findings accurately, including circumstances in which the available evidence remains inconclusive.

9. Recognize Warning Signs When Choosing a Private Investigator

Prospective clients should approach certain claims with caution.

Potential warning signs include:

• Guaranteed investigative results.

• Promises of unrestricted access to confidential records.

• Refusal to provide verifiable licensing information.

• Unclear billing arrangements.

• Pressure to authorize unnecessary services.

• Claims that unlawful surveillance or account access is acceptable.

• Unwillingness to explain investigative limitations.

Professional confidence should not be confused with exaggerated certainty.

An experienced investigator should understand that outcomes depend on circumstances that cannot always be predicted or controlled.

From Our Investigative Perspective: The Right Questions Matter More Than Quick Promises

Consider a hypothetical situation involving an attorney attempting to locate a witness whose last known address is several years old.

A poorly defined assignment might begin with broad searches that consume time without establishing which information is reliable.

A more disciplined approach would first evaluate the available identifying information, determine what sources may be legally accessed, assess potential leads, and establish a process for verification.

The distinction is not simply the amount of investigative activity performed.

It is whether the activity is directed toward a clearly defined objective.

This principle applies across investigative assignments, from surveillance to missing-person searches and corporate investigations.

At TJS Private Investigations, we believe clients should expect investigative planning that reflects professional reasoning, lawful methods, and an understanding of the assignment's practical limitations.

Our Perspective: Choosing an Investigator Is About Trust, Judgment, and Reliable Information

Hiring a private investigator often involves circumstances that are personal, sensitive, or legally significant.

Clients may be seeking information that affects family relationships, financial decisions, business operations, or legal proceedings.

For that reason, selecting an investigative agency should involve more than comparing advertisements or hourly rates.

We believe the foundation of professional investigative work is the ability to assess information objectively, select appropriate investigative methods, document findings accurately, and communicate results responsibly.

Experience matters, but so do professional judgment and ethical responsibility.

An investigator should recognize when evidence is insufficient, when an investigative method is inappropriate, and when a client's expectations require clarification.

What we recommend is straightforward: verify credentials, ask informed questions, understand the proposed investigative process, and choose a professional who values factual accuracy over guaranteed outcomes.

Reliable investigative assistance should help clients make informed decisions, not create additional uncertainty through unsupported claims.
