The Short Answer
A Rockwall County DWI is prosecuted by the Rockwall County District Attorney and heard at the Rockwall County courts. Misdemeanors go to the County Courts at Law and felonies to the District Courts. The license case runs separately: an ALR hearing must be requested within 15 days of the notice of suspension.
DWI Defense in Rockwall
Facing a DWI in Rockwall County?
Deandra Grant Law defends people charged with DWI in Rockwall and across Rockwall County, from Royse City and Fate to Heath and the Rockwall side of Rowlett. We handle every level of the offense, from a first DWI to high-BAC, repeat, and felony charges. Our Ridge Road office sits four minutes from the Rockwall County Courthouse, where every case in the county is heard.
Rockwall is the smallest county in Texas by area, and its courts run on familiarity: a small bench, a DA’s office that knows its docket, and cases that move on local rhythm. That is an advantage for a defense team that is in the building constantly and a problem for one that is not. This firm brings more than 500 trials to verdict and a forensic lawyer-scientist who wrote The Texas DWI Manual to a county where most DWIs begin as an I-30 traffic stop, which means most of them begin with a stop worth challenging.
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.
15-Day Deadline
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 DWI in Rockwall County
Rockwall runs its DWI cases differently from the counties around it. These are the local specifics that shape a defense here.
Where your case is heard
Every Rockwall County criminal case is heard at the Rockwall County Courthouse, 1111 E. Yellowjacket Lane. Misdemeanor DWIs go to the County Court at Law, felonies to the District Court.
Who prosecutes
The Rockwall County Criminal District Attorney's office is small enough to know every case on its docket and organized into dedicated divisions. Familiarity runs both directions here, and we are a known quantity in that building.
The I-30 corridor
Most Rockwall DWI arrests start as a traffic stop on I-30. That makes the legality of the stop the first battleground in a Rockwall case, and reasonable suspicion is a requirement, not a formality.
Challenging the stopWhere your blood goes
Rockwall blood draws are sent out for testing, and the receiving lab's records are discoverable. We request the underlying data in every blood case.
Jail release
After a Rockwall arrest you're booked at the Rockwall County Detention Center, adjacent to the courthouse. Bond is set at magistration, usually within 48 hours.

We Read the Lab
A Rockwall blood case rests on an outside lab's work. We request the chromatograms, calibration records, and QC data behind the number, and we challenge the chemistry.
After You Hire Us
What We Actually 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’s destroyed
- Pull the full discovery file: offense report, calibration and maintenance logs, lab records, certifications
- Read the underlying chemistry ourselves: the chromatograms, 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 isn’t right, which is why the offers get better
We quote a flat fee after a consultation at no cost to you, so the investment is known before you commit.
