Getting arrested for DWI in Houston doesn’t just mean dealing with the police — it means entering a court system that can feel like a maze, where every wrong turn could cost you. Knowing which Houston courts handle DWIs before you walk through those doors can make a real difference in how you approach your defense.
Here’s a quick look at how court assignment generally breaks down by charge level:
- Municipal courts: Class C misdemeanor DWIs (rare, minor circumstances)
- County criminal courts at law: Most first and second offense DWIs (Class A and B misdemeanors)
- District courts: Felony DWIs (third offense, intoxication assault, intoxication manslaughter)
But here’s the thing. Houston sprawls across multiple counties, and the courthouse you actually end up in depends heavily on where you were arrested. Harris County works differently from Fort Bend and Montgomery counties, and the differences matter.
No matter which court your case lands in, you need someone who knows how to fight — and win — inside all of them. Mark Thiessen is a quadruple board-certified DWI lawyer in Houston with 140+ Not Guilty verdicts and a track record that speaks for itself.

First and second offense DWI (Class A & B misdemeanor)
Most DWI arrests in the Houston area result in Class A or Class B misdemeanor charges — and for the majority of people reading this, this is where your case is headed. As mentioned, the courthouse you walk into depends entirely on where you were arrested.
Harris County
If you were arrested for DWI in Harris County — whether that’s inside the city of Houston, Pasadena, Baytown, or any of the surrounding areas — your misdemeanor DWI case will be assigned to one of the 16 Harris County Criminal Courts at Law. These courts have exclusive jurisdiction over Class A and Class B misdemeanors, including the vast majority of first and second offense DWI charges.
All 16 of these courts operate out of the Harris County Criminal Justice Center at 1201 Franklin, Houston, TX 77002 in Downtown Houston. This is also where you’ll find the Harris County District Attorney’s Office and the Harris County District Clerk — so if you have any business related to your case, chances are it’s happening in this building.
Five of the 16 Criminal Courts at Law are designated as S.O.B.E.R. courts — Saving Ourselves By Education and Recovery. It’s a Harris County-exclusive rehabilitation program for high-risk DWI offenders that can substitute treatment for incarceration. It’s voluntary, not everyone qualifies, and it’s not always the right call even if you do. Before you consider entering any kind of plea or program, talk to an attorney first.
Fort Bend County
If you were arrested in Sugar Land, Missouri City, Richmond, Rosenberg, or anywhere else in Fort Bend County, your misdemeanor DWI will be heard in one of the Fort Bend County Courts at Law. Courts 2, 4, and 6 specifically handle DWI cases — and all of them are housed in the same building at the Fort Bend County Justice Center, located at 1422 Eugene Heimann Circle, Richmond, TX 77469.
Fort Bend County also operates a unique DWI Court program with two tracks: Tier 1 for first-time offenders and Tier 2 for those with a prior DWI conviction. Tier 1 functions as a pre-trial diversion program — complete it successfully, and your case can be dismissed. Again, these programs aren’t for everyone, and whether they’re a good fit for your situation is exactly the kind of call you should be making with a qualified DWI attorney, not on your own.
Montgomery County
Arrested in The Woodlands, Conroe, Spring, or elsewhere in Montgomery County? Your misdemeanor DWI will be assigned to one of three Montgomery County Courts at Law that handle criminal cases — specifically Courts at Law 1, 4, and 5. All three are located in the Atrium Building at 210 West Davis, Conroe, TX.
Montgomery County has a reputation for prosecuting DWI cases aggressively, which makes having the right representation even more critical if you’re facing charges there.
Felony DWI (third offense, intoxication assault, intoxication manslaughter)
A felony DWI is a completely different animal. Whether you’re facing a third offense, an intoxication assault charge, or the most serious charge of all — intoxication manslaughter — the stakes are dramatically higher, and so are the courts that handle them. Jail time isn’t the only thing on the line; a felony conviction can follow you for the rest of your life.
Harris County
Felony DWI cases in Harris County are handled by the Harris County District Courts — 22 criminal district courts in total, all located at the Harris County Criminal Justice Center at 1201 Franklin, Houston. Don’t let the shared address fool you — these courts carry far more firepower. District courts have exclusive jurisdiction over any offense that carries a potential prison sentence of more than one year, which includes third-offense DWI, intoxication assault, and intoxication manslaughter.
If you’re facing felony DWI charges in Harris County, you are not in a position to figure this out alone. The question of Houston DWI lawyer cost and fees often comes up at this stage — and while legal representation is an investment, the cost of walking into a Harris County felony court without a serious defense attorney is far greater.
Fort Bend County
Felony DWI charges in Fort Bend County are handled by one of 8 Fort Bend County District Courts, all located at the Fort Bend County Justice Center, 1422 Eugene Heimann Circle, Richmond, TX 77469, alongside the misdemeanor courts.
The 8 district courts are the 240th, 268th, 328th, 387th, 400th, 434th, 458th, and 505th Judicial District Courts. While Fort Bend’s misdemeanor courts have some flexibility in how they route cases, felony charges go straight to district court — and the District Attorney’s Office in Fort Bend County does not take these cases lightly.
Montgomery County
If your felony DWI charge originated in Montgomery County, your case will be heard in one of the 7 Montgomery County District Courts, all located at the Montgomery County Courthouse in Conroe — separate from the Atrium Building where the misdemeanor Courts at Law operate. The courts are actually spread across multiple addresses, but the primary address used for the district court/clerk is 301 North Main Street, Conroe, TX 77301.
Montgomery County’s reputation for aggressive DWI prosecution extends to its felony courts — if you’ve been charged with intoxication assault or intoxication manslaughter in this county, the word “serious” doesn’t begin to cover it.
Whatever county you’re in, whatever charge you’re facing — a felony DWI requires a DWI lawyer in Houston with the credentials, the courtroom experience, and the track record to actually fight for you. Not just show up.
What happens when you get a DWI in Texas and have a court hearing?
Once your case is assigned to the right court, the real fight begins. Every court we’ve covered above follows the same basic process — but what happens inside that process, and how it plays out for you, depends heavily on your charge, your county, and who’s in your corner.
Here’s a quick look at what to expect:
- Arraignment: Your first court appearance, where you enter a plea of guilty, not guilty, or no contest
- Pretrial hearings: Your attorney can challenge evidence, file motions, and negotiate with the prosecution
- Trial: If your case doesn’t resolve before trial, it goes before a judge or jury
- Sentencing: If convicted, the court determines penalties, including fines, license suspension, and potential jail time
- Appeals: A conviction isn’t necessarily the end — you may have grounds to appeal
The court process for a DWI in Texas is its own topic entirely, and the details matter. For a full breakdown of what to expect from start to finish, read our guide on the Texas DWI court process. Here’s what we’ll tell you right now: no matter which court your case lands in, how you navigate that process makes all the difference.
FAQs
Which court in Texas has jurisdiction over DWI cases?
It depends on your charge and where you were arrested. Misdemeanor DWIs are handled by County Criminal Courts at Law, while felony DWIs — third offenses, intoxication assault, intoxication manslaughter — go to District Courts.
In the Houston area, the specific courthouse you end up in comes down to whether you were arrested in Harris, Fort Bend, Montgomery, or another surrounding county.
Do I need a lawyer for DWI?
Do I need a lawyer for DWI? Technically, you can show up without one, but walking into any of the courts covered in this article without experienced representation is a serious mistake. The prosecutors in Harris, Fort Bend, and Montgomery County know these courtrooms inside and out — you need someone in your corner who does too.
Can you be charged with DWI days later?
Can you be charged with DWI days later? Yes — in Texas, blood test results can take days or even weeks to come back, and charges can be filed after the fact once that evidence is in hand. That means you could be looking at a court date in Harris, Fort Bend, or Montgomery County without ever having been formally arrested at the scene, which is all the more reason to have an attorney lined up before anything is filed.
Walking into a Houston DWI court without Thiessen Law Firm in your corner is a mistake you can’t take back.
Knowing which Houston court your DWI case is headed to is step one. Step two is making sure you have someone in that courtroom who has been there before, who knows the prosecutors, and who has the credentials and the record to actually win.
