Criminal Defense Lawyers Serving Round Rock, Texas

The Hull Firm represents individuals in Round Rock, TX charged with criminal offenses in Williamson County courts. Our attorneys are former prosecutors — they have built criminal cases from the state’s side and now use that same knowledge to defend you. With over 700 case dismissals across Travis, Williamson, and Hays County courts and 20+ years of combined criminal defense experience, The Hull Firm is the team Round Rock residents trust when the stakes are high.

Round Rock is Williamson County's largest city with approximately 140,000 residents, situated along IH-35 between Austin and Georgetown. Criminal charges filed in Round Rock route through Round Rock Municipal Court for Class C matters and the Williamson County court system for all higher-level charges — with all Williamson County District Court and Courts at Law proceedings held at the Williamson County Justice Center in Georgetown. The presence of major employers including Dell Technologies, IKEA, and numerous retail and logistics operations generates significant daily commuter traffic on IH-35 and US-79, corridors where DWI enforcement and traffic stop-based drug arrests are consistently documented.

Round Rock residents facing criminal charges are prosecuted by the Williamson County District Attorney's Office, which has historically been one of the more aggressive DA offices in Central Texas. Understanding how Williamson County prosecutors evaluate DWI cases versus drug cases versus assault allegations — and what arguments produce results with each prosecution team — requires consistent practice in those courts. The Hull Firm has that experience.

A criminal charge in Round Rock can put your freedom, professional license, firearm rights, and future employment at risk. Even a misdemeanor conviction creates a permanent record that follows you on every background check. The Hull Firm pursues dismissal as the first goal in every case and builds the legal record to support that outcome from the day you call.

Why Round Rock Residents Choose The Hull Firm

⚖

Former Prosecutor on Your Side

Allison Tisdale prosecuted criminal cases in Texas courts before moving to criminal defense. Mark Hull has spent 20+ years on the defense side of the courtroom. They understand exactly how Williamson County prosecutors evaluate evidence, what arguments carry weight in each courtroom, and where cases built on weak stops, questionable searches, or credibility gaps fall apart under challenge.

⚖

700+ Cases Dismissed

Dismissal is the first goal in every case we accept. Over 700 criminal case dismissals across Travis, Williamson, and Hays County courts reflect a disciplined, aggressive approach to identifying constitutional violations, evidentiary weaknesses, and legal defects that produce results for clients.

⚖

24/7 Emergency Response

Arrests in Round Rock don’t happen on a schedule. The Hull Firm answers calls around the clock, provides emergency jail-release support, and begins working your case immediately — not after paperwork is filed or an arraignment is scheduled. The day you call is the day we start.

⚖

Deep Williamson Court Knowledge

Round Rock criminal cases route through Round Rock Municipal Court for city-level matters and Williamson County courts for misdemeanor and felony prosecution. The Hull Firm appears regularly in both venues, knows the assigned judges and prosecution teams, and builds defense strategy around how those courts actually operate.

Why the First 72 Hours After a Round Rock Arrest Matter Most

After a criminal arrest in Round Rock, the Williamson County District Attorney’s Office begins evaluating the case immediately. Body camera footage, 911 recordings, witness statements, and officer narratives are gathered before most defendants have spoken with an attorney. The decisions you make in the first three days directly determine what options you will have for the rest of the case.

Early legal intervention in Round Rock criminal cases allows The Hull Firm to:

  • Preserve body camera footage and surveillance recordings before automatic overwrite cycles delete them permanently — most law enforcement systems overwrite within 30 to 90 days
  • Identify and document constitutional violations in the arrest, search, traffic stop, or interrogation process while the record is still fresh and challengeable
  • Engage the Williamson County DA’s Office during the pre-filing review stage — sometimes preventing the most serious charge from being filed at all
  • Secure bond conditions that allow you to maintain employment, housing, and family contact while the case moves through the court system
  • Prevent you from making recorded statements, social media posts, or informal admissions that the prosecution will use against you at every subsequent stage
  • File an ALR hearing request within the 15-day window for DWI arrests before automatic license suspension takes effect

The Hull Firm begins working your case the day you call. For Round Rock residents and their families, that means calling 512-599-9999 as soon as possible after an arrest — any time of day or night.

Criminal Defense Services for Round Rock, TX Residents

The Hull Firm handles the full range of criminal charges brought in Round Rock Municipal Court and Williamson County courts. Each practice area below represents a dedicated defense capability with specific strategies for the courts, judges, and prosecution teams that handle these cases.

⚖

DWI & DUI Defense — Round Rock & Williamson County

DWI defense in Round Rock requires challenging the Williamson County prosecution on every element: the legality of the traffic stop, the administration of standardized field sobriety tests, the accuracy of breath or blood testing, and whether the officer had sufficient probable cause at each stage. A first-offense DWI conviction in Texas is a Class B misdemeanor carrying up to 180 days in county jail, a fine up to $2,000, and a 90-day to one-year license suspension. A second offense is a Class A misdemeanor with mandatory jail time. A third offense is a third-degree felony.

IH-35 through Round Rock is one of the most heavily DWI-patrolled corridors in Williamson County. Round Rock Police Department conducts regular saturation patrols, and Williamson County Sheriff's deputies operate along US-79 and the surrounding area. The 15-day ALR window runs from the day of arrest — and Williamson County prosecutors are known for aggressive DWI prosecution.

⚖

Assault & Family Violence Defense — Round Rock

Assault charges in Round Rock and Williamson County range from Class C misdemeanor threats to first-degree felony aggravated assault. A family violence designation carries consequences far beyond the criminal case, including a lifetime federal firearm prohibition under 18 U.S.C. §922(g)(9) that cannot be expunged in Texas and immediate implications for any child custody or family court matter.

Round Rock's dense residential neighborhoods — including Teravista, Forest Creek, and the areas surrounding University Boulevard — generate domestic disturbance calls that are among the most common drivers of arrest in the city. Williamson County's Family Violence Unit pursues a no-drop prosecution approach, meaning cases are prosecuted even when the complaining witness later recants.

Assault Defense Overview → Simple Assault → Aggravated Assault → Family Violence & Domestic Assault →
⚖

Drug Charge Defense — Round Rock, TX

Drug charges in Round Rock and Williamson County are prosecuted by penalty group classification and quantity. Possession of less than one gram of a Penalty Group 1 substance is a state jail felony carrying 180 days to two years. Quantities above four grams elevate to second-degree felony territory. Most drug cases in Round Rock begin with traffic stops on IH-35, US-79, and University Boulevard — and the Fourth Amendment challenge to the stop and the search is often the most powerful defense available.

IH-35 is a primary drug interdiction corridor for both Round Rock PD and the Williamson County Sheriff's Office. Traffic stops along IH-35 and US-79 generate a significant portion of the drug possession and delivery arrests prosecuted in Williamson County courts. Fourth Amendment challenges to the basis for the stop and the scope of the search are the most effective defense tools in these cases.

Drug Charge Defense Overview → Marijuana Possession → Controlled Substance → Drug Trafficking & Distribution →
⚖

Theft & Property Crime Defense — Round Rock

Theft charges in Texas are tiered by value from Class C misdemeanor (under $100) through first-degree felony ($300,000 or more). Even a Class B misdemeanor theft conviction creates a permanent record that appears on every employment and housing background check indefinitely. Round Rock’s retail and commercial corridors generate shoplifting and retail theft arrests prosecuted in Williamson County courts — and a conviction at any level can follow a Round Rock resident for life.

The Hull Firm challenges the state’s evidence in theft cases by contesting valuation methods used to elevate charges, challenging identification reliability, scrutinizing loss prevention procedures, and identifying intent disputes where the facts do not support the prosecution theory. Deferred adjudication, pre-trial intervention, and outright dismissal are outcomes The Hull Firm pursues for qualifying Round Rock clients.

Theft Crimes Defense → White Collar Crimes →
⚖

Probation Violations & Protective Order Defense

A probation violation allegation in Williamson County can result in immediate arrest and incarceration while you wait for a revocation hearing. The state needs to prove the violation only by a preponderance of the evidence — a significantly lower bar than beyond a reasonable doubt. The Hull Firm evaluates the alleged violation, challenges the evidentiary support, and negotiates with the supervising probation officer and the Williamson County DA to pursue alternatives to full revocation.

Protective order violations carry serious immediate consequences: a Class A misdemeanor for a first violation, a third-degree felony for a subsequent violation. The Hull Firm advises Round Rock clients on compliance with protective order terms from day one and defends against alleged violations aggressively when they arise.

⚖

Juvenile Defense & Record Expungement — Round Rock

Juveniles charged in Williamson County are adjudicated in Williamson County Juvenile Court, but the consequences of a juvenile adjudication can reach well into adulthood, affecting educational opportunities, military eligibility, and professional licensing. Early legal intervention is as urgent in juvenile cases as in adult criminal matters — often more so, given the lifetime trajectory at stake.

For Round Rock residents with prior arrests, dismissed charges, or completed deferred adjudication sentences, Texas Chapter 55 expungement or an Order of Nondisclosure may be available to clear or seal the record. The Hull Firm evaluates eligibility for all record-clearing options, manages all Williamson County court filings, and represents clients through the complete proceedings required to achieve a clean result.

What Round Rock Residents Need to Know About Texas Criminal Charges

A criminal charge in Round Rock, Texas is prosecuted under Texas state law in either Round Rock Municipal Court or Williamson County courts depending on charge level. Every criminal charge — from a Class C misdemeanor citation to a first-degree felony — creates an arrest record that appears on background checks until and unless it is expunged or sealed. Texas criminal records do not expire, do not fall off on their own, and are not automatically sealed after a period of time.

Texas misdemeanor penalties: Class C misdemeanor — fine up to $500, no jail time; Class B misdemeanor — up to 180 days in county jail, fine up to $2,000; Class A misdemeanor — up to one year in county jail, fine up to $4,000. Even a Class A misdemeanor with a family violence designation triggers the same federal firearm prohibition as a felony conviction under 18 U.S.C. §922(g)(9).

Texas felony penalties: state jail felony — 180 days to two years; third-degree felony — 2 to 10 years; second-degree felony — 2 to 20 years; first-degree felony — 5 to 99 years or life. All felony levels carry fines up to $10,000 and trigger collateral consequences including federal firearm prohibitions, restrictions on professional licenses, and in some cases registration requirements.

Deferred adjudication — available for many charge types but not DWI or assault with a deadly weapon — allows the court to defer a finding of guilt while the defendant serves probation. If completed successfully, the charge is dismissed and a nondisclosure order may be available to seal the record. Whether it applies to your Round Rock case is a legal analysis The Hull Firm performs during every free initial consultation.

How The Hull Firm Handles Your Round Rock Criminal Case

From your first call to the final resolution, here is exactly how The Hull Firm approaches criminal defense for Round Rock, TX clients in Williamson County courts.

1

Immediate Case Evaluation

Your first call connects you directly with a licensed defense attorney — not a receptionist. We evaluate the charge, the arrest circumstances, and the available evidence and give you an honest assessment of realistic outcomes the same day you call.

2

Evidence Preservation

Once retained, we move immediately to obtain all available body camera footage, 911 recordings, dispatch records, incident reports, and surveillance video. We issue preservation demands while evidence is still accessible — overwrite cycles on body cam footage typically run 30 to 90 days.

3

Defense Strategy

We identify the primary defense theory early — constitutional violation, insufficient evidence, self-defense, false accusation, or a charge-specific technical defense — and build the factual and legal record to support it before the Williamson County DA’s Office can harden its position.

4

Pre-Trial Motions

We challenge inadmissible evidence through suppression motions, contest the constitutionality of the stop or search, and file pretrial motions that create leverage for negotiations. Being genuinely prepared to suppress key evidence changes how the Williamson County DA values your case at every stage.

5

Negotiation & Trial

We negotiate with the Williamson County DA’s Office from informed strength, knowing what arguments carry weight with the assigned prosecution team. When negotiation does not produce an acceptable outcome, The Hull Firm is prepared to take the case to trial in Williamson County courts.

6

Record Clearing

After a case resolves by dismissal, acquittal, or successful completion of deferred adjudication, we evaluate whether expungement or a nondisclosure order is available and manage the complete Williamson County court filing process to clear or seal your record as quickly as the law allows.
