San Marcos Criminal Defense Lawyer — DWI, Assault, Drug Charges & More

Your case will be heard at the Hays County Government Center — 712 S. Stagecoach Trail, San Marcos. Class A and B misdemeanors go to Courts at Law No. 1, 2, or 3 on the second floor. Felonies go to one of five District Courts on the third floor: the 22nd, 207th, 274th, 428th, or 453rd. DA Kelly Higgins prosecutes everything — felonies, misdemeanors, juvenile cases. we appear in all of these courts regularly and we know how this office operates.

Hays County prosecutes cases hard. There are fewer diversion programs here than in Travis County, and the DA’s office doesn’t go easy on first-time offenders the way some other counties do. Most of the DWI and drug cases we handle from this area start with a traffic stop on IH-35, US-290, or the frontage roads between Kyle and San Marcos. The first thing we look at is whether that stop was legal — because if it wasn’t, the evidence may not be usable and the case can fall apart.

Allison Tisdale was a Texas state prosecutor before she joined me at our firm. That means on any given case, we have the prosecution’s perspective built into our defense strategy — we know what Kelly Higgins’s office looks for, what moves them in negotiations, and where their cases have weaknesses. Call 737-937-5786 the day of your arrest. There’s a window right after an arrest — before charges are formally filed — where we can sometimes get out ahead of things. That window closes fast.

Why Hire a Hays County Criminal Defense Attorney?

A conviction in Texas stays on your record permanently. It shows up on employer background checks, landlord screenings, professional license applications — nursing, real estate, teaching, CDL. Even a misdemeanor guilty plea can cost you a job or a license years later. And unlike Travis County, Hays County doesn’t have robust pre-trial diversion programs to fall back on. When we take your case, our goal is dismissal — not damage control, not pleading it down to something that still shows up. Dismissal, or we take it to trial. That applies whether you're facing a DWI, drug charges, an assault charge, or anything else in Hays County.

Serving Kyle, Buda, Wimberley & All of Hays County

we handle cases throughout Hays County and the surrounding counties. Kyle and Buda are growing fast — both are right on IH-35 and both see heavy enforcement. Wimberley arrests usually happen on RR-12 or FM-3237 on weekends. Lockhart and Luling go through Caldwell County courts. New Braunfels goes through Comal County. we appear in all of them. If you were arrested anywhere between Austin and San Antonio and you’re not sure which court your case is in, call me at 737-937-5786 and I’ll tell you exactly what you’re facing.

San Marcos Criminal Defense Practice Areas

Every case we take in Hays County starts with the same goal: get the charge dismissed. Below are the charge types we handle most often in San Marcos, Kyle, Buda, and the surrounding courts.

15-Day ALR Deadline

DWI / DUI Defense

IH-35 through Hays County is one of the most actively enforced DWI corridors in Central Texas. Your license suspension clock starts the day of arrest. We file the ALR request and build your defense immediately.

Assault Charges

Simple assault through aggravated assault with a deadly weapon. Charges range from a Class A misdemeanor to a first-degree felony. We challenge probable cause, witness credibility, and the evidence used at arrest.

Domestic Violence & Family Violence

The Hays County Family Justice Unit pursues family violence charges even when the complaining witness recants or refuses to cooperate. A conviction triggers a permanent federal firearm prohibition. Early intervention is critical.

Drug Charges

PG 1 possession under 1 gram is a state jail felony. THC concentrate is PG 2 — not marijuana — and carries felony penalties for any amount. Most drug cases begin with a traffic stop on IH-35. The Fourth Amendment analysis of that stop is the defense foundation.

Weapons Charges

Unlawfully Carrying a Weapon (UCW) is frequently charged alongside DWI and drug arrests in Hays County. Even valid LTC holders face UCW exposure when arrested for another offense. A weapons conviction can result in permanent loss of gun rights.

Probation Violations

A motion to revoke probation in Hays County can result in the full original sentence being imposed. There is no deferred adjudication on DWI, so MTR hearings on DWI probation carry particularly high stakes. We appear at MTR hearings and bond hearings the same day you call.

IH-35 Corridor: San Marcos, Kyle & Buda Criminal Arrests

we know IH-35. It’s one of the most heavily enforced stretches of highway in Central Texas — DPS Troopers, Hays County Sheriff’s deputies, Kyle Police, and Buda Police all run regular enforcement along this corridor. Most of the drug cases we handle from this area start with a minor traffic stop — a speeding ticket, an improper lane change, a cracked taillight — that escalated when the officer claimed he smelled marijuana or saw something in plain view. Under the Fourth Amendment and Texas Code of Criminal Procedure Chapter 38, that escalation has to be legally justified. When it isn’t, we move to suppress the evidence. Suppressed evidence usually means a dismissed case.

On DWI arrests along IH-35, your license is on the line from day one — separate from the criminal case. You have 15 days from your arrest to request an Administrative License Revocation hearing with Texas DPS. If you miss that deadline, your license is automatically suspended, no matter what happens in court. we file that request the day you hire us. We fight the criminal case and the ALR hearing at the same time.

If you were arrested on IH-35 in Kyle, San Marcos, or Buda — or anywhere in Hays County — call me at 737-937-5786 today.

How a San Marcos Criminal Defense Attorney Fights Your Charges in Hays County

Here’s how I approach every criminal case in Hays County — from the day you call to the day your case closes.

01

Immediate case review & ALR filing

On DWI cases, we file the ALR request the day you hire us — your license is our first priority. On every case, we pull the offense report, dashcam and bodycam footage, lab reports, and all available evidence immediately. we want to see everything before the prosecution has a chance to build its story.

02

Fourth Amendment analysis

Most drug and DWI cases start with a traffic stop. we look at whether that stop was legally justified, whether the officer extended the detention past what was allowed, and whether any search had valid legal basis. If the stop or the search was illegal, we file a motion to suppress. Get that evidence thrown out, and the prosecution usually has no case left.

03

Evidence challenges

On DWI cases we dig into how the field sobriety tests were administered, the maintenance records on the breathalyzer, and the chain of custody on any blood draw. On drug cases we look at how the substance was identified, what lab methods were used, and whether the penalty group was correctly applied. On assault cases I challenge the complainant’s credibility, the injury documentation, and whether the officer actually had probable cause to arrest.

04

Hays County DA negotiations

Allison spent years prosecuting cases for the state of Texas before she joined me. She knows exactly how the Hays County DA’s office thinks — what they value in evidence, where they have room to move, and what arguments they take seriously. When we negotiate with prosecutors, we’re not guessing. we know what moves them toward dismissal.

05

Trial preparation

we prepare every case for trial from day one. That’s not a negotiating tactic — we genuinely prepare to try every case. When the DA’s office knows your lawyer actually goes to trial, the negotiating dynamic is completely different. we’ve tried cases in Hays County, Travis County, Williamson County, and surrounding courts for over 20 years. we’re not afraid of a courtroom.

06

Expungement after dismissal

Getting your charge dismissed is step one. But that arrest still shows up on background checks until a court issues a formal expunction order under Texas Chapter 55. we evaluate expungement eligibility on every case we handle, and we take care of the entire filing — petition, service, order — so your record actually reflects what happened.

Criminal Defense for Texas State University Students in San Marcos

Texas State has over 38,000 students in San Marcos, and we see a lot of cases from that campus. DWI on the way back from Austin, drug possession at a house party, assault charges from a bar fight on Hopkins Street — these are the most common ones. A conviction doesn’t just mean fines or probation. It can cost you your financial aid, get you removed from campus housing, and show up on every background check for the rest of your career. If you’re a student, call me the same day you get arrested — the earlier we get involved, the more we can do.

SMPD and Hays County Sheriff’s deputies patrol the IH-35 frontage roads, Cheatham Street, and the North LBJ Drive corridor hard on weekends and during events. Getting arrested here doesn’t mean a conviction — but you need someone who knows these courts and understands what’s at stake academically, not just legally. Whether you’re a student in San Marcos, a resident in Kyle or Buda, or someone passing through on IH-35, call me at 737-937-5786 as soon as you can.

San Marcos & Hays County Criminal Defense FAQ

These are the questions we hear most from people who’ve just been arrested in Hays County. we’ve answered them with specific local details — courts, deadlines, how this DA’s office operates.

Your case will be at 712 S. Stagecoach Trail — the Hays County Government Center in San Marcos. Class C citations go to San Marcos Municipal Court or the JP courts. Class A and B misdemeanors are on the second floor in Courts at Law No. 1, 2, and 3. Felonies are on the third floor in the 22nd, 207th, 274th, 428th, or 453rd District Courts. DA Kelly Higgins’s office handles all of it. we appear in all of those courts and in the surrounding counties — Caldwell and Guadalupe included.

If you got a DWI anywhere in Hays County — San Marcos, Kyle, Buda, on IH-35, anywhere — you have 15 days from the arrest to request an ALR hearing with the Texas DPS. Miss that deadline and your license gets suspended automatically, no hearing, no appeal. we file that request the day you hire us. Call 737-937-5786 immediately — not tomorrow, today.

Yes — and we’ve secured Over 930 dismissals or rejected cases since 2021 across Central Texas, including in Hays County. Most drug and DWI cases start with a stop on IH-35, US-290, or FM-150. If that stop wasn’t legally justified, we file a Fourth Amendment suppression motion under Texas Code of Criminal Procedure Chapter 38 — and when the evidence gets suppressed, the prosecution usually folds. Assault cases are different — those turn on credibility and early intervention before the DA’s office builds its narrative. Call me the same day. The window before charges are filed is your best window.

No — deferred adjudication doesn’t exist for DWI in Texas. That option is completely off the table by statute. A DWI conviction is permanent the second it enters — it can’t be sealed, can’t be nondisclosed, and can be used to enhance your sentence on a future charge years from now. The only way to protect your record on a DWI is dismissal or acquittal, followed by expungement. That’s why we fight every DWI case for dismissal, not just a better plea.

Much more serious than Travis County. Austin has cite-and-release and diversion programs that Hays County simply doesn’t offer — especially on Penalty Group 1 charges. IH-35 through Hays County is an active interdiction route. DPS and the Sheriff run regular enforcement specifically to catch drug trafficking. If you picked up a drug charge on that stretch, you need someone who knows how this particular DA’s office handles these cases — not someone who primarily practices in Austin.

we handle cases throughout Hays County — San Marcos, Kyle, Buda, Wimberley, Dripping Springs, and the smaller communities. I also appear in Caldwell County for cases in Lockhart and Luling, Guadalupe County for Seguin, and Comal County for New Braunfels. If you got arrested on IH-35 anywhere between Austin and San Antonio and you’re not sure which county your case is in, call me at 737-937-5786 — we’re available around the clock.

Yes — until we expunge it. A dismissal doesn’t wipe the arrest from background checks automatically. The arrest stays visible until a court issues a formal expunction order under Texas Chapter 55. Most people assume a dismissal means the record goes away. It doesn’t. we check expungement eligibility on every case we close and handle the entire filing if you qualify.

Say this out loud: ‘we’re invoking my right to remain silent. we want an attorney.’ Then stop talking. Don’t explain yourself to the officer. Don’t consent to any search. Don’t call the other party in an assault case. Write down everything you remember about the stop while it’s still clear. Then call me at 737-937-5786 — we’re available 24 hours a day and we start working your case the same day.

Hire someone who actually shows up in Hays County courts — not someone who lists San Marcos on their website but drives in from Austin twice a year. You want a lawyer who knows DA Kelly Higgins’s office, knows how the five District Court judges operate, and knows the rhythm of misdemeanor court in the Courts at Law. On a DWI case, local ALR hearing experience matters a lot. we’ve practiced in Hays County courts for over 20 years. Call 737-937-5786 and ask us directly about our record here.

Much more serious than Travis County. Austin has cite-and-release and diversion programs that Hays County doesn’t offer. Here, PG 1 possession under 1 gram — cocaine, heroin, fentanyl, meth — is a state jail felony: 180 days to 2 years. And that THC vape cartridge? That’s PG 2, not marijuana — it’s treated as a felony for any detectable amount under 1 gram. Most of these cases start with a traffic stop on IH-35. The first question I ask is whether that stop was legal — because that’s where most of these cases get won or lost.

Both Kyle and Buda are in Hays County — so your Class A or B misdemeanor or felony will be handled at the Government Center at 712 S. Stagecoach Trail in San Marcos. Class C matters like traffic tickets or public intox might go to Kyle Municipal Court at 111 N. Front Street, Buda Municipal Court at 405 E. Loop Street, or the JP Precinct 2 court in Kyle at 5458 FM 2770. we handle cases from Kyle, Buda, and every other city in Hays County. Call 737-937-5786 and I’ll confirm exactly where your case was filed.

If your DWI was dismissed or you were acquitted at trial, yes — you can petition for expungement under Texas Chapter 55. That order requires every agency to destroy the record: courts, DPS, police departments, private background check companies. But if you were convicted, there’s no path to sealing it. No deferred, no nondisclosure — a DWI conviction in Texas is permanent. That’s exactly why we fight every DWI for dismissal rather than settling for a plea. If your DWI was dismissed and you haven’t filed for expungement yet, call 737-937-5786. That eligibility window doesn’t stay open forever.
