When you’re facing a divorce in the Dallas-Fort Worth Metroplex, information isn't just power: it's the currency of your future. Whether you’re navigating a high-conflict custody battle in Collin County or a complex property division in downtown Dallas, the evidence you bring to the table can change everything.
At Armstrong Investigations, PLLC, we often get asked the same question: "Do I need someone following my spouse with a camera, or do I need someone to look into their phone?" The truth is, the answer depends entirely on what you’re trying to prove. Both traditional surveillance and digital forensics have their place in a modern Texas divorce, but they serve very different purposes.
In this guide, we’ll break down the pros and cons of each, how they work together, and why a tech-forward approach to surveillance is usually the winning play for DFW residents.
The Classic Approach: Physical Surveillance
Physical surveillance is exactly what you see in the movies: but with more paperwork and better cameras. It involves a licensed private investigator discreetly following a subject to document their real-world actions. In the DFW area, this might mean tracking a spouse from an office in Las Colinas to a suspicious meeting in Southlake.
When Physical Surveillance Wins
Physical surveillance is still the gold standard for proving conduct. While a text message might suggest an affair, a high-resolution video of your spouse entering a hotel with someone else at 2:00 AM is much harder to explain away in court.
- Proving Cohabitation: If you are trying to prove that a former partner is living with someone new: which can impact certain support arrangements: physical surveillance is essential.
- Child Safety and Custody: This is perhaps the most critical use. If you suspect your spouse is neglectful or under the influence while they have the kids in Denton or Rockwall County, we can document their behavior in real-time. We see who is actually picking the kids up from school and what’s happening during those weekend visits.
- Lifestyle and Habit Evidence: Is your spouse claiming they are "job hunting" while actually spending all day at the golf course in Frisco? Surveillance provides the visual proof that contradicts their sworn statements.
The Limits of the "Stakeout"
The main downside? It’s time-consuming. We can follow someone for ten hours and, if they stay home and watch Netflix, we’ve documented a very boring day. It also doesn't tell us what’s happening inside the house or on their screens.
The Modern Edge: Digital Forensics
If physical surveillance is about what someone does, digital forensics is about what someone thinks and says. We live our lives on our devices. From the Apple Watch on our wrists to the infotainment system in our trucks, we leave a digital breadcrumb trail everywhere we go.
The Power of Data
Digital forensics involves the recovery and analysis of data from smartphones, computers, tablets, and cloud accounts. In a North Texas divorce, this is often where the "smoking gun" is found.
- Recovering Deleted Content: Just because a message was deleted doesn't mean it's gone. Professional forensic tools can often pull "ghost" data from a device that the average person thinks is erased forever.
- GPS and Location History: We can often reconstruct a spouse’s movements over the last six months using location data. If they claim they were "at the office in Fort Worth" every Tuesday night, but their phone’s GPS puts them at a residence in Arlington, the evidence speaks for itself.
- Social Media Evidence: In 2026, social media is a goldmine. We look for "hidden" profiles, burner accounts, and interactions that reveal a lifestyle inconsistent with what’s being reported to the court.
A Warning on DIY Snooping
We have to be very clear here: Do not try to be your own forensic expert. Texas has strict laws regarding the interception of communications and unauthorized access to devices. If you "hack" your spouse's email or use a keylogger without professional guidance, you might find that the evidence is inadmissible in court: or worse, you could face legal trouble yourself. We always recommend pre-divorce investigation planning to ensure everything is done legally and ethically.
Asset Tracing and Hidden Income
One of the biggest battlegrounds in DFW divorces: especially in high-net-worth areas like Highland Park or Southlake: is money. When one spouse handles the finances, the other often suspects "hidden" accounts or "skimmed" income.
This is where the two methods converge. Digital forensics can find the digital footprint of a secret offshore account or a Venmo history that suggests undisclosed spending. Physical surveillance can then be used to document a spouse visiting a luxury property or driving a vehicle they claim they don't own.
Whether you are in Johnson County or Ellis County, we work to uncover:
- Undisclosed bank accounts or cryptocurrency wallets.
- Property held in the name of friends or family members.
- "Lifestyle vs. Income" discrepancies (e.g., claiming $50k in income while spending $200k).
Navigating Texas Law: Support and Equality
When discussing the financial side of a divorce, it’s important to understand how the law works here in the Lone Star State.
Temporary Spousal Support
In Texas, we do not use the term "alimony" in the traditional sense you might hear in other states. Instead, we have Temporary Spousal Support. It’s important to note that this is only available in a select number of cases and is usually intended to maintain the status quo while the divorce is pending. Our investigative work often focuses on proving the financial need (or lack thereof) to help the court make an informed decision on these payments.
Same-Sex Relationships
Since the 2015 Obergefell v. Hodges decision, same-sex couples in Texas are treated exactly the same as opposite-sex couples in all family law issues. Whether your divorce is in Tarrant, Collin, or Dallas County, the same rules of evidence and property division apply. We bring the same level of professional scrutiny and care to every case, regardless of the parties involved.
Why You Need Both
In our experience, the most successful cases use a hybrid approach. Digital evidence gives us the "who, what, and when," and physical surveillance gives us the "how."
Imagine this scenario: Digital forensics reveals your spouse is messaging someone about a "secret trip" to a lake house in Kaufman County. We then use physical surveillance to capture video of them arriving at that house, proving the meeting actually happened. Separately, they are pieces of a puzzle. Together, they are a complete picture.
Choosing Your Strategy in the DFW Metroplex
The cost of a private investigator in Dallas can vary based on the methods used. Digital forensics often has a higher upfront cost for device imaging and analysis, while physical surveillance costs are usually billed by the hour.
We recommend starting with a consultation to determine your specific goals. Are you trying to secure primary custody? Are you trying to prove a breach of fiduciary duty regarding community property?
