FAQ

Common Questions About This Firm

How quickly do I need to act after a Texas DWI arrest?
Critical: you have only 15 days from the arrest to request an ALR hearing or your driver's license will be automatically suspended. Trey Porter Law can file the ALR request the same day you call — but only if you call in time.
Will my DWI case go to trial?
Most DWI cases resolve through pretrial motions, plea negotiation, or pretrial diversion. The firm prepares every case for trial because trial readiness produces better outcomes — even when the case never sees a jury.
Can a Texas DWI conviction be expunged?
Generally no — DWI convictions are not eligible for expunction in Texas. However, many pre-trial dispositions, deferred adjudications on certain offenses, and dismissed cases are eligible for expunction or non-disclosure. The firm will assess your record and tell you what's possible.
Should I take the breath/blood test?
Texas implied consent law penalizes refusal. Both compliance and refusal have legal consequences. The firm regularly challenges the science, calibration, and chain of custody of breath and blood evidence — many DWI cases are won at this stage.
Why is Trey Porter Law more expensive than some firms?
Specialization and experience. The firm focuses on DWI and criminal defense, which means deeper familiarity with the science, the prosecutors, and the judges — and historically better outcomes. For a charge that affects your license, your job, and your record, the cost differential is usually well-justified.
