Facing a DWI in Denton County?
Deandra Grant Law defends people charged with DWI in Denton, Lewisville, Flower Mound, and across Denton County. Our Denton office sits directly across McKinney Street from the Denton County Courts Building, so the building where your case will be heard is one we are in constantly. Call (940) 600-5536 any hour. Denton is also a college county. UNT and TWU put tens of thousands of students under 21 on the road, and Texas enforces a zero-tolerance rule for drivers under 21, where any detectable alcohol can support a charge. An underage DWI or a DUI by a minor in Denton is a different case from a standard first offense, and it needs a lawyer who treats it that way.
The Denton County Criminal District Attorney runs a dedicated DWI Unit, which means these cases are handled by prosecutors who do nothing else. That raises the bar, and it is the bar we are built to meet. This firm has tried more than 500 cases to verdict, and when the State’s case rests on a breath or blood result, we request the underlying data and challenge the analysis rather than taking the reported result at face value.
Getting started costs nothing. Call or schedule online to talk through what happened and understand your options. The sooner we start, the more we can protect, and in Texas you have just 15 days from the notice of suspension to request the hearing that keeps your license.
Your license is on a 15-day clock
It starts when you receive the notice of suspension, not automatically at arrest. Denton sends blood out to a state DPS lab and the wait is often long, so in a blood case that notice may arrive by mail weeks later. The deadline may still be ahead of you. Request the hearing either way.

The BWI rulesHow a DWI Case Moves Through Denton County
Denton runs its DWI docket differently from Dallas, Tarrant, or Collin. Here is the path from the arrest to the end of the case. Find where you are on it.
Arrest
Denton County DWI arrests come from Denton Police, DPS troopers on I-35E and US-380, the Denton County Sheriff's Office, UNT and TWU police near the campuses, and the suburban departments in Lewisville, Flower Mound, The Colony, and Corinth.
Booking
After the arrest you are booked at the Denton County Jail. Lewisville, Flower Mound, and other city arrests may hold you locally first.
Bond and release
A magistrate sets your bond and any release conditions, usually within 48 hours and before your first court date. Time already spent in the county jail counts against any sentence later.
Blood analysis
Denton County sends DWI blood out to a state DPS lab for analysis. Turnaround is often slow, and that delay is part of the case: it stretches the license timeline and it gives the defense time to work. The lab's methods, calibration records, and quality control data are discoverable, and we request them in every blood case.
ALR hearing
Your license case runs separately from the criminal case. Request the hearing within 15 days of the notice of suspension, and the hearing becomes the first chance to question the officer under oath.
The 15-day ruleFirst setting
Your case is set at the Denton County Courts Building, 1450 E. McKinney Street, a few blocks east of the downtown square. A first or second DWI is a misdemeanor and goes to a County Criminal Court. A felony DWI, intoxication assault, or intoxication manslaughter goes to a District Court.
Who prosecutes
The Denton County Criminal District Attorney's Office runs a dedicated DWI Unit staffed by prosecutors who handle nothing else. The State's side of your case is run by specialists, which makes generic defense work easy for them to beat.
Resolution
Denton County runs an active DWI Court, a probation-based treatment program for repeat DWI offenders that has operated since 2007, alongside a Veterans Treatment Court. Neither is a diversion for a first offense, so for most cases the defense itself is the path to a dismissal, a reduction, deferred adjudication where you qualify, or a verdict at trial.
Why 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.
We quote a flat fee after a consultation at no cost to you, so the investment is known before you commit.

Denton DWI Attorneys in the Denton County Courts
Forensic-science training, three decades of Texas defense, and the courtroom record to back it up.
As Seen In
Serving All of Denton County
We defend DWI cases from every corner of Denton County: Denton itself, from the Square and the UNT and TWU campuses outward, plus Lewisville, Flower Mound, Highland Village, Corinth, Lake Dallas, The Colony, Little Elm, Aubrey, Sanger, Krum, Pilot Point, Argyle, Roanoke, and Trophy Club. If the arrest happened in Denton County, the case lands at the Denton County Courts Building, and those are courtrooms we work every week. Some cities cross a county line: the Denton County side of Frisco and Carrollton is heard here, while stops on the other side belong to Collin or Dallas County. The far north edge of Fort Worth also reaches into Denton County. We check the county first, because it decides everything that follows.
Lewisville, The Colony, and Corinth
The I-35E corridor south of Denton produces a steady share of the county arrests, from Lewisville PD, The Colony PD, Corinth PD, and DPS, and Lake Lewisville adds boating-while-intoxicated cases every summer. All of it is heard in Denton. Our Lewisville DWI attorney page covers that stretch in detail.
Flower Mound and Highland Village
FM 2499, FM 407, and the roads around Grapevine Lake are Flower Mound and Highland Village police territory, and every arrest there is a Denton County case. See our Flower Mound DWI lawyer page.
UNT, TWU, and Fry Street
Denton is a college town, and a stop near campus by UNT police, TWU police, or Denton PD is prosecuted by the same Denton County DWI Unit. A driver under 21 faces the Texas zero-tolerance rule, where any detectable alcohol supports a charge, and a DWI can carry school conduct consequences on top of the criminal case.
