Facing a DWI in Rockwall County?
Deandra Grant Law defends people charged with DWI in Rockwall and across Rockwall County, from a first offense to felony DWI, drugged driving, and boating while intoxicated on Lake Ray Hubbard. Our Rockwall office sits on Ridge Road, minutes from the Rockwall County Courthouse, so the building where your case will be heard is one we are in constantly. Call (469) 253-6999 any hour.
Rockwall is the smallest county in Texas by area, and its docket runs personal. The same judges, the same prosecutors, the same courtrooms, week after week. Showing up prepared and credible in that building matters more here than almost anywhere, and it is where more than 500 trials to verdict earn their keep. Most Rockwall DWIs begin as a traffic stop on I-30, which means most of them begin with a stop worth challenging, and when blood is drawn it goes to the DPS crime lab in Garland, where we request the underlying data in every case.
Getting started costs nothing. Call or schedule online to talk through what happened and understand your options. In Texas you have just 15 days from the notice of suspension to request the hearing that keeps your license, so the sooner we start, the more we can protect.
Your license is on a 15-day clock
It starts when you receive the notice of suspension, not automatically at arrest. In a blood case that notice often arrives by mail weeks later, so the deadline may still be ahead of you. Request the hearing either way.

The BWI rulesHow a DWI Case Moves Through Rockwall County
The smallest county in Texas runs its docket its own way. Here is the path from the arrest to the end of the case. Find where you are on it.
Arrest
Most Rockwall County DWI arrests start as a traffic stop on I-30 by DPS troopers or Rockwall Police, with Heath, Fate, and Royse City police and the Rockwall County Sheriff's Office making the rest. That makes the legality of the stop the first battleground in a Rockwall case, and reasonable suspicion is a requirement, not a formality. On Lake Ray Hubbard, game wardens make stops on the water that police never could on a road, and a BWI carries DWI-grade consequences and counts as a prior.
Challenging the stopBooking
After the arrest you are booked at the Rockwall County Detention Center on T.L. Townsend Drive, at the Sheriff's Office a short distance from the courthouse.
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 detention center counts against any sentence later.
Blood analysis
Rockwall County sends DWI blood to the DPS crime lab in Garland, the same lab Denton and Collin use. The turnaround is often slow, and that lab's methods, calibration records, and analysts are all discoverable. We request the underlying data 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 Rockwall County Courthouse, 1111 E. Yellowjacket Lane. A first or second DWI is a misdemeanor and goes to the County Court at Law. A felony DWI, intoxication assault, or intoxication manslaughter goes to a District Court in the same building.
Who prosecutes
The Rockwall County Criminal District Attorney's Office. A small office means the same prosecutors see your lawyer's work case after case, and reputation in the building is part of the defense. We are a known quantity there.
Resolution
A Rockwall DWI ends one of four ways: dismissal, reduction, deferred adjudication on a qualifying first offense, or a verdict at trial. In a county this small, which of those is on the table depends on how the case was built from the first setting, and on the boat as much as the road: a BWI follows the same path.
The BWI rulesWhy Rockwall Clients Choose This Firm
What decides a DWI case is how well your lawyer understands the evidence, and how well the courthouse knows your lawyer.
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.

As Seen In
Serving All of Rockwall County
We defend DWI cases from every corner of Rockwall County: Rockwall, Heath, Fate, Royse City, McLendon-Chisholm, and the I-30 corridor along Lake Ray Hubbard that produces most of the county’s arrests. If the arrest happened in Rockwall County, the case is heard at the Rockwall County Courthouse, and those are courtrooms we work every week. Two lines to know: Rowlett straddles the Dallas County line, so a stop on the Dallas side is a Dallas County case, and Royse City reaches into Collin and Hunt counties. We check the county first, because it decides the courthouse, the prosecutor, and the plan.
Royse City and Fate
The I-30 growth corridor east of the lake books through fast-growing departments, and DPS and the two city police departments make a large share of the county’s stops there. Fate arrests are Rockwall County cases. Royse City spans Rockwall, Collin, and Hunt counties, so the side of the line the stop happened on decides the courthouse, and we sort that before anything else.
Heath and Rowlett
The lakeshore cities split across county lines. Heath is Rockwall County, and a Heath stop is heard at the same courthouse as a Rockwall stop. Rowlett is mostly Dallas County with a Rockwall County edge, so a Rowlett stop can be a Rockwall case or a Dallas County case heard at Frank Crowley instead. Which side of the line decides everything, and we appear in both.
Forney and Kaufman County
Just south on the interstate, Forney and Terrell arrests are Kaufman County cases, heard at the Kaufman County Justice Center rather than in Rockwall. Our Kaufman County courts guide covers that docket, and the Rockwall office handles those cases too.
