Dallas County Criminal Courts Guide
By Attorney Deandra Grant
If you’re facing a criminal charge in Dallas County, understanding how the local courts work can make the process far less confusing. This guide explains where cases are heard, what each court handles, and what you can expect as your case moves through the system.
Read NowIrving DWI Lawyers
A DWI arrest in Irving, Texas, can jeopardize your career, your professional licenses, and your freedom. Irving’s location along major highway corridors (including Highway 183, Highway 114, and State Highway 161) makes it one of the most active DWI enforcement areas in Dallas County. Officers from both Irving PD and DFW Airport Department of Public Safety patrol these corridors aggressively, particularly on weekends and during events at Toyota Music Factory and the entertainment district.
Irving DWI cases are prosecuted in Dallas County’s County Criminal Courts at the Frank Crowley Courts Building. First-offense DWI is a Class B misdemeanor; repeat offenses, DWI with a child passenger, and intoxication assault or manslaughter are felonies heard in the Criminal District Courts.
The Scientific Advantage in DWI Defense
DWI cases are built on scientific evidence: blood alcohol concentration from breath or blood tests, field sobriety test observations, and toxicology reports for drug-related impairment. Challenging this evidence requires more than legal knowledge. It requires scientific training.
While other firms in Dallas County may hold the ACS-CHAL Lawyer-Scientist designation, Deandra Grant is the only attorney who combines it with a Master’s Degree in Pharmaceutical Science. That involved years of graduate study in drug metabolism, pharmacokinetics, and toxicology. This scientific foundation goes far beyond any course designation, giving her the ability to challenge forensic evidence at its roots.
How We Challenge DWI Evidence
- Blood Test Challenges: GC-FID and GC-MS instrument calibration, sample preservation, chain of custody, in vitro fermentation, coelution of interfering compounds
- Breath Test Challenges: Partition ratio variability, mouth alcohol contamination, instrument maintenance records, operator certification
- Field Sobriety Test Challenges: NHTSA protocol deviations, medical conditions affecting performance, environmental factors, officer training deficiencies
Drug DWI: Pharmacokinetic analysis of absorption and elimination rates, therapeutic vs. impairing doses, tolerance considerations — areas where the pharmaceutical science degree is decisive

Frequently Asked Questions After a DWI Arrest: Answers from Deandra Grant Law – Criminal & DWI Defense
Facing a DWI arrest in Texas can leave you with a whirlwind of questions and uncertainties. At Deandra Grant Law – Criminal & DWI Defense, we understand the importance of providing you with accurate information to help you make informed decisions about your situation. Below, we’ve compiled answers to some of the frequently asked questions individuals like you often have after a DWI arrest.
Do I Need a Lawyer for My DWI Case?
While you have the right to represent yourself, having an experienced Texas DWI attorney can significantly improve your chances of a favorable outcome. DWI cases involve complex legal procedures and potential consequences. A skilled attorney can guide you through the process, build a solid defense, and protect your rights.
What Happens to My Driver's License?
After a DWI arrest, your driver’s license could be suspended. You typically have a limited time to request an Administrative License Revocation (ALR) hearing to challenge the suspension. A DWI attorney can assist you in navigating this process and fighting to retain your driving privileges.
Can I Refuse a Breathalyzer or Field Sobriety Tests?
While you have the right to refuse these tests, there can be consequences, such as an automatic driver’s license suspension. Refusal might also be used as evidence against you. Consulting with an attorney can help you understand the pros and cons of your decision in your specific situation.
What Are the Penalties for a DWI Conviction in Texas?
DWI penalties vary based on factors such as prior convictions and the circumstances of the offense. Penalties can include fines, license suspension, probation, mandatory alcohol education programs, and even jail time. A knowledgeable attorney can assess the details of your case to provide an estimate of potential penalties.
Can I Fight a DWI Charge Even If I Failed Sobriety Tests?
Yes, failing sobriety tests doesn’t automatically make you guilty. Field sobriety tests can be influenced by various factors, including nervousness, medical conditions, and even road conditions. An attorney can examine the test procedures, possible errors, and other evidence to challenge the validity of the results.
Will I Have to Go to Trial?
Not necessarily. Many DWI cases are resolved through negotiation or plea bargains, resulting in reduced charges or alternative sentencing options. However, if a trial becomes necessary, having a skilled attorney is essential to present your defense effectively.
Can I Expunge a DWI from My Record?
In Texas, a DWI conviction cannot be expunged, which means it will remain on your record permanently. However, there might be opportunities for record sealing or obtaining a pardon in certain cases. Consulting with an attorney can provide insight into your options.
