Suspecting that a partner is being unfaithful is one of the most painful experiences a person can endure. In the fast-paced environment of the Dallas-Fort Worth (DFW) Metroplex, where long commutes and busy corporate schedules are the norm, infidelity often finds plenty of places to hide. From the high-rises of Downtown Dallas to the suburban sprawl of Collin and Denton counties, the complexity of modern relationships and the ease of digital communication have made uncovering the truth more difficult than ever.
At Armstrong Investigations, PLLC, we understand the emotional turmoil that comes with these suspicions. However, finding the truth isn't just about peace of mind: it's about legal strategy, financial protection, and preparing for the next chapter of your life. Whether you are in Tarrant, Rockwall, or Johnson County, knowing the "secrets" of professional surveillance can make the difference between a successful legal outcome and a disastrous legal liability.
The Secret the "Pros" Don't Always Tell You: Timing is Everything
Most people believe they should file for divorce first and then hire a private investigator to gather evidence. In Texas, this is often the biggest mistake you can make.
Since the passage of House Bill 2715 in 2023, Texas law has significantly tightened the restrictions on surveillance once a divorce is initiated. Courts now have the power to bar one spouse from tracking or physically following the other as part of standard temporary restraining orders (TROs). If you wait until the papers are served to start your infidelity investigation, you might find yourself legally barred from conducting the very surveillance you need to prove your case.
This is why pre-divorce investigation is a critical secret of the industry. At Armstrong Investigations, PLLC, we emphasize the importance of gathering evidence before the legal battle begins. This allows for discreet, legal, and effective observation from public vantage points: evidence that can then be used to influence property division and negotiations for Temporary Spousal Support.
Why DIY Tracking is a Legal Landmine in Texas
With the rise of "spy apps" and cheap GPS trackers available online, many individuals in Dallas and Fort Worth attempt to take matters into their own hands. This is a dangerous gamble.
Texas has strict laws regarding privacy and the interception of communications. Under the "one-party consent" rule, you can generally record a conversation you are part of, but bugging a room or a vehicle to record a conversation between your spouse and a third party is a felony. Furthermore, installing a GPS tracker on a vehicle that you do not have a primary legal right to can lead to criminal stalking charges.
A private detective knows the boundaries of the law. Professional surveillance services rely on high-end equipment and years of experience to gather evidence that is actually admissible in a Texas courtroom. If you obtain evidence illegally, not only will a judge likely throw it out, but you could also face a civil lawsuit for invasion of privacy or even criminal prosecution.

Surveillance Across the DFW Metroplex: A Regional Strategy
The geography of North Texas plays a major role in how an infidelity investigation is conducted. Tracking a subject from a corporate office in Plano (Collin County) to a restaurant in Fort Worth (Tarrant County) requires a deep understanding of the local landscape.
Armstrong Investigations, PLLC provides Dallas surveillance that covers the entire DFW area, including:
- Dallas County: Navigating the dense traffic of the Tollway and the nightlife of Uptown.
- Collin & Denton Counties: Discreetly operating in residential neighborhoods and high-end shopping districts like Legacy West.
- Rockwall, Ellis, Kaufman, & Johnson Counties: Handling the unique challenges of more rural or suburban outskirts where "outsiders" are more easily noticed.
A true DFW private investigator doesn't just follow a car; they anticipate patterns. We look for "lifestyle" changes: sudden trips to the gym at odd hours, new credit card charges at local DFW hotspots, or frequent "business meetings" that don't align with a normal corporate schedule.
The Financial Secret: Waste of Community Assets
In Texas, adultery can have a significant impact on the "just and right" division of community property. While Texas is a "no-fault" divorce state, judges can and do consider fault when dividing assets.
One of the most effective tools in an infidelity investigation is not a camera, but a paper trail. This is where legal investigative services and background checks come into play. We look for evidence of "waste of community assets." If your spouse has been using joint funds to pay for hotels, expensive dinners, jewelry, or travel for a paramour in the Dallas area, those funds can often be "reconstituted" back into the estate, meaning you could receive a larger share of the remaining assets to make up for what was spent on the affair.

Infidelity and Same-Sex Relationships
It is important to note that in the State of Texas, the law applies equally to everyone. Since the 2015 Obergefell v. Hodges decision, same-sex couples are treated exactly the same as opposite-sex couples in all Texas family law issues, including divorce, property division, and infidelity. Whether your case involves a traditional marriage or a same-sex union, the standards for proving a waste of community assets or establishing grounds for a disproportionate share of the estate remain consistent. Armstrong Investigations, PLLC provides the same high-level professional surveillance and discretion to all clients across the DFW Metroplex.
Understanding Private Investigator Cost
One of the most common questions we hear is: "What is the private investigator cost for an infidelity case?"
The truth is that every case is unique. Factors that influence the cost include:
- Duration: How many days or hours of surveillance are required to catch a pattern of behavior?
- Manpower: Do we need multiple investigators to track a subject through heavy Dallas traffic or multiple exits?
- Technology: Are we utilizing specialized digital forensics or deep background checks?
At Armstrong Investigations, PLLC, we are transparent about our fees. We provide a detailed breakdown of costs and work closely with your legal team to ensure that the investigation is a sound investment that provides a clear return in your divorce settlement.
