When the stakes are high, strategy matters.
Tank Law PLLC represents people facing DWI charges, navigating divorce or custody matters, recovering from injuries caused by someone else's negligence, and businesses working through commercial disputes across Dallas–Fort Worth. Focused practice areas. One deliberate approach.
DWI Defense
A DWI charge moves fast — and what happens in the first few days can shape the rest of the case. We examine the stop, the testing, and the evidence before anyone accepts the state's version of events.
- First-offense DWI
- Repeat / second & third DWI
- BAC .15 or higher
- DWI with open container
- DWI involving an accident
- DWI with a child passenger
- License suspension & ALR hearings
- Intoxication assault
- Intoxication manslaughter
- Related alcohol-driving offenses
Personal Injury
Serious injuries create real financial pressure while you're still trying to heal. We handle the insurance company, document the damages, and build the claim while you focus on recovery.
- Car accidents
- Commercial truck accidents
- Rideshare accidents
- Pedestrian accidents
- Motorcycle accidents
- Premises liability
- Wrongful death
- Serious injury claims
Family Law
Divorce and custody matters affect your children, your finances, and your day-to-day life all at once. We help clients move through the process with a clear plan — protecting what matters most while keeping conflict in check where possible.
- Divorce (contested & uncontested)
- Child custody & conservatorship
- Child support — establishment
- Child support — modification
- Child support — enforcement
- Possession & visitation schedules
- Property & asset division
- Spousal support
- Paternity matters
- Post-divorce modifications
Commercial Litigation
When a contract breaks down or a business relationship turns into a dispute, the early moves often decide how it ends. We help Dallas–Fort Worth businesses and owners resolve disputes efficiently — and litigate them decisively when negotiation isn't enough.
- Breach of contract
- Partnership & shareholder disputes
- Non-compete & non-solicitation disputes
- Trade secret disputes
- Business torts
- Vendor & supplier disputes
- Commercial lease & real estate disputes
- DTPA claims
- Injunctive relief
- Business dissolution disputes
Good legal representation starts before the courtroom.
Every case requires a strategy. We identify the problem, understand the evidence, anticipate the opposition, and develop the strongest path forward. Whether you're facing a DWI charge or recovering from a serious injury, Tank Law approaches the case deliberately — not reactively.
Identify
What actually happened, and what the record shows so far.
Understand
The evidence, the testing, the reports, and where they're weak.
Anticipate
How the state or the insurance company will argue the case.
Prepare
A path forward built to negotiate — or to try the case.
William Wallace III
William Wallace III founded Tank Law on a simple premise: clients facing a DWI charge or recovering from a serious injury deserve an attorney who prepares every case as though it will end up in front of a jury — because sometimes it does.
He works closely with clients from the first consultation through resolution, focusing his practice exclusively on DWI defense and personal injury so that every case gets the depth of attention it needs.
"I didn't know what to expect after my arrest. Tank Law explained exactly what was happening at every step and never made promises they couldn't keep — that honesty mattered."— Former DWI Defense Client
