    DWI Defense in Denton

    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.

    15-Day Deadline

    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.

    What We Defend

    Denton DWI Charges We Handle

    Every Denton County DWI charge, from a first offense to intoxication manslaughter, including underage DWI and DUI by a minor.

    First-Offense DWI

    Driving while intoxicated with no prior convictions, a Class B misdemeanor.

    First DWI penalties

    Second DWI

    A DWI with one prior conviction, a Class A misdemeanor with mandatory jail time.

    Second DWI penalties

    Third DWI

    A DWI with two prior convictions, a third-degree felony carrying two to ten years.

    Third DWI penalties

    DWI, BAC 0.15+

    A result of 0.15 or higher raises a first DWI to Class A.

    Why 0.15 matters

    DWI with Child Passenger

    A passenger under fifteen turns a misdemeanor DWI into a felony.

    Why this is a felony

    Intoxication Assault

    Causing serious bodily injury to another while intoxicated, a third-degree felony.

    Assault penalties

    Intoxication Manslaughter

    Causing a death while intoxicated, a second-degree felony carrying prison time.

    Manslaughter penalties

    Underage DWI

    Drivers under twenty-one face DUI charges for any detectable amount of alcohol.

    DWI vs. DUI

    Drug DWI

    A DWI where the intoxicant is a drug, prescribed or illegal, with no breath number involved.

    How they prove it

    Marijuana DWI

    Marijuana and edibles can support a DWI without any measurable level.

    The marijuana rules

    Prescription Drug DWI

    A valid prescription is no defense if the medication impaired your driving.

    Prescription rules

    CDL DWI

    A commercial license is disqualified even for a DWI in your own car.

    CDL consequences

    Boating DWI (BWI)

    Operating a boat while intoxicated, prosecuted much like a driving DWI.

    The BWI rules
    Local Knowledge

    How 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 rule

    First 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.

    A state lab's results have the same failure points as any lab's. We request the chromatograms, calibration records, and QC data behind the number, and we challenge them at the chemistry level, not just the paperwork.
    Learn More About Our Firm
    After You Hire Us

    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.

    Amazing! Kevin really cared.. my son was not just another money sign. He put his whole heart into getting my son a “Not Guilty” verdict.

    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.

    Denton County

    Denton DWI Questions, Answered

    Which court will my Denton County DWI case be in?

    At the Denton County Courts Building, 1450 E. McKinney Street. Misdemeanor DWIs go to the County Criminal Courts, felonies to the District Courts. Our office is directly across the street, and our Denton County guide covers the building.

    What's different about Denton's DWI Unit?

    Your prosecutor handles intoxication cases exclusively. That means shortcuts get punished and prepared defenses get respected. We build every Denton case for a specialist audience, starting with the defenses that actually work.

    They took my blood in Denton County. Is my case over?

    No. Denton sends DWI blood out to a state lab, and a lab result has failure points: the warrant affidavit, the draw, the chain of custody, preservation, the analyst's method, and the instrument's own maintenance record. The wait for the result is often where the defense begins. Our guide to the evidence in a Texas DWI case explains what we look for.

    My child got a DWI at UNT or TWU. What happens now?

    Texas applies a zero-tolerance rule to drivers under 21, so any detectable alcohol can support a charge, and a DUI by a minor is a different charge from an adult DWI. Denton County sees a high volume of these because of its universities, and the license and record consequences for a young person are worth taking seriously from the first week. Parents are welcome on the consultation, in person or by video.

    Will UNT or TWU find out about the arrest?

    They can. Both universities' student conduct codes reach off-campus arrests, and a DWI or DUI by a minor can open a conduct case through the Dean of Students that runs on its own timeline, under a lower standard of proof than the criminal court uses. The county does not send the school a notice, but a campus police stop, a probation condition, or a conviction can put the arrest in front of it. How and when to handle the school side depends on the school and the facts, and it is part of the plan from day one, not an afterthought.

    Denton County runs a treatment court. Could that help me?

    Maybe. Denton County's DWI Court has run since 2007 as a probation-based treatment program for repeat DWI offenders: intensive treatment, a SCRAM monitor, an ignition interlock, and frequent court appearances over 15 to 18 months. The county also runs a Veterans Treatment Court. Neither is a diversion for a first offense, and eligibility is narrow, so whether your case fits is one of the first things we check.

    I was arrested in Lewisville or Flower Mound. Do you handle that?

    Yes. Every Denton County city prosecutes at the county courts building. You may sit in a city jail briefly before transfer. Wherever the stop happened, we defend it. See our Denton County guide.

    How long do I have to save my license after a Denton DWI?

    15 days from the notice of suspension to request an ALR hearing, or the suspension is automatic. Inside the window, call today. Past it, an occupational license may keep you driving.

    Can a first DWI in Denton County end without a conviction?

    It can. Since September 1, 2019, Texas law lets a judge grant deferred adjudication on a first DWI when your alcohol concentration was under 0.15, you have no prior conviction under the intoxication statutes, and you did not hold a commercial license at the time. An ignition interlock is a required condition, and the decision is the judge's, not automatic. Deferred is not a dismissal, but the case ends without a final conviction. It is not available where a child was in the car, or on intoxication assault or intoxication manslaughter. Our guide to deferred adjudication covers who qualifies and what it does to your record.

    What does a DWI lawyer in Denton cost?

    It depends on the charge and whether the case is headed to trial, and we are direct about numbers at the first call. The consultation costs nothing and we offer payment plans. Our fee guide explains what a DWI defense should and should not cost.

    I was just arrested for DWI in Denton County. What should I do first?

    Call us. Two clocks start at once: the 15-day window to request an ALR hearing and keep your license, and the window to preserve the in-car and body-camera video before it is overwritten. Our step-by-step guide covers the rest: What to Do After a DWI Arrest.

    Do I have to come to the Denton office, or can we meet remotely?

    Either. Many clients meet us in person at the Denton office, directly across the street from the courts building, but the first consultation works just as well by phone or video, so you can get advice the same day, even before you are able to come in. In-person visits are also available at any of our six Texas offices.

    Can you handle my case if I was arrested outside Denton County?

    Yes. We defend DWI cases across North and Central Texas from six offices and route your case to the attorney and courthouse that fit. Cooke County cases at the Gainesville courthouse are handled from this office too. Find your county on our locations page.

    Will I go to jail for a first DWI in Denton County?

    The statute allows it: a first-offense DWI carries 72 hours to 180 days in the county jail, and up to a year if the result was 0.15 or higher. In practice a first offense in Denton County more often ends in a dismissal, a reduction, deferred adjudication where you qualify, or probation, and the jail exposure is what the defense is built to remove. The time you already spent in the Denton County Jail after the arrest counts against any sentence.
