Facing a DWI in Lewisville?
Deandra Grant Law defends people charged with DWI in Lewisville and along the I-35E corridor, including The Colony, Corinth, Highland Village, Lake Dallas, and Little Elm. We handle every level of the offense, from a first DWI to high-BAC, repeat, and felony charges, including DWI with a child passenger, intoxication assault, and drugged driving. A Lewisville stop is a Denton County case: Lewisville PD, The Colony PD, Corinth PD, DPS, and the sheriff’s office all charge through the Denton County District Attorney, and every one of those cases is heard at the Denton County Courts Building in Denton.
That is where our Denton office is, directly across McKinney Street from the building that will hear your case. Denton County prosecutes DWI through a dedicated DWI Unit, prosecutors who handle nothing else, so the defense has to know the evidence better than the people who built it. This firm has tried more than 500 cases to verdict and is led by a managing partner who wrote The Texas DWI Manual. In a blood case we request the lab’s underlying data, the chromatograms and calibration records, and read it at the chemistry level.
Getting started costs nothing. Call or schedule online to talk through what happened. You have just 15 days from the notice of suspension before your license suspension becomes automatic.
Arrested in the last 15 days?
Your license is on its own clock. It starts when you receive the notice of suspension, which in a blood case often arrives by mail weeks later.
What Actually Happens to a Lewisville DWI
A Lewisville arrest runs on Denton County's rules. These are the local specifics that shape a defense here.
Where your case is heard
Not in Lewisville. Every Denton County DWI is heard at the Denton County Courts Building, 1450 E. McKinney Street in Denton, misdemeanors in the County Criminal Courts at Law and felonies in the District Courts. Our office is directly across the street.
Who prosecutes
The Denton County Criminal District Attorney runs a dedicated DWI Unit. Whether the stop was Lewisville PD on I-35E, The Colony PD, or a DPS trooper, the prosecutor across the table works intoxication cases exclusively.
Jail release
Lewisville and other Denton County cities may hold you at a city facility first, then transfer you to the Denton County Jail. Bond is set at magistration, usually within 48 hours.
Where your blood goes
Denton County blood draws are sent out for testing, and the receiving lab's methods, calibration records, and quality control data are discoverable. Denton also runs no-refusal periods, when a breath test refusal can turn into a warrant and a blood draw the same night.
Pretrial programs
Denton County runs a DWI Treatment Court and a Veterans Court, and its alternative tracks and their DWI eligibility change over time. Whether your case qualifies is one of the first things we check.

The BWI rulesWhy Denton Clients Choose This Firm
What decides a DWI case is how well your lawyer understands the evidence.
What We Do on Every Case
From the first call, in order:
- Request your ALR hearing before the 15-day deadline and use it to question the officer under oath.
- Demand the dash and body camera video before it is destroyed.
- Pull the full discovery file: offense report, calibration and maintenance logs, lab records, certifications.
- Read the underlying chemistry ourselves: the chromatograms and the QC data, not the summary report.
- Re-score the field sobriety tests against NHTSA protocol, on video.
- File the motions the evidence supports, because suppression is how DWI cases end.
- Build your mitigation file, with clinical assessments, at no cost to you.
- Try the case if the offer is not right. Prosecutors know which firms try cases.
Intake answers 24/7, and if we can take your case, the consultation with an attorney is free. We quote a flat fee there, so the investment is known before you commit.
