How much does it cost to hire a private investigator?
Cost depends on the type of investigation, its complexity, and the time and resources required. Surveillance, background checks, and locates each carry different fee structures. We provide a clear estimate after an initial confidential consultation, so you understand the investment before any work begins.
Yes. Licensed investigators may lawfully conduct surveillance and document activity that occurs in public or in plain view. What the law prohibits is trespassing, illegal recording, and other invasive methods. Because our firm is led by a Juris Doctor and operates under a Texas DPS license, we ensure every method we use stays firmly within the law.
People hire us when they need verifiable facts: suspected infidelity, child-safety and custody concerns, hidden assets in a divorce, background vetting of a partner or hire, locating a missing person, or evidence to support litigation. If a decision turns on the truth, an investigator can help establish it.
We serve the entire Dallas–Fort Worth Metroplex, with a core focus on Dallas, Tarrant, Collin, and Denton counties, and we regularly work in surrounding counties such as Rockwall, Ellis, Kaufman, and Johnson. Statewide coverage is available for qualifying matters.
A straightforward background check can often be completed within a few business days, while more comprehensive investigations involving asset research or multiple jurisdictions take longer. We will give you a realistic timeline up front based on the scope of what you need.
Yes. Through financial research, public-record analysis, open-source intelligence, and, where appropriate, surveillance, we identify undisclosed accounts, property, and income. This is among our most requested services in high-net-worth divorce and litigation matters.
We do. We document the conditions and conduct that matter in custody, abuse, and neglect proceedings, including supervision, living environment, and compliance with court orders. Our findings are gathered lawfully and presented objectively to support a parent’s case and protect the child.
Absolutely. Confidentiality is the foundation of our practice. Your identity and the details of your matter are protected to the fullest extent permitted by law, and sensitive materials are secured and accessed only by those directly involved in your case.
Frequently. We serve as an investigative extension of legal teams, providing witness location, statement support, scene documentation, and organized, court-ready evidence. Our J.D.-led approach means we understand exactly what your case requires.
A background check is a structured review of records, history, and public information about a person or entity. An investigation is broader and more active, often combining records research with surveillance, interviews, and field verification to answer a specific question. Many matters call for both.
Texas recognizes same-sex marriage, and same-sex spouses have the same rights and obligations in divorce, custody, and property matters as any other married couple. We approach every family-law matter with the same professionalism and respect regardless of the spouses’ genders. This is general information, not legal advice; consult a licensed attorney for guidance on your specific situation.
Texas allows for temporary spousal support during a divorce and, in limited circumstances, post-divorce spousal maintenance under the Texas Family Code. Evidence of income, lifestyle, and conduct can be relevant to these determinations, which is one reason thorough investigation matters. This is general information, not legal advice; consult a licensed attorney about your particular case.
