Message us if you have ANY question about Texas criminal law and we will try our best to answer it for you. You should know your rights as both a Texas citizen and as an American. Persons with authority are less likely to take advantage of an educated citizen. Therefore, one principal purpose of our site is to help the public understand the laws that govern their everyday life. DWI and Drug laws can be particularly confusing. Should I blow if pulled over? Should I allow a policeman to search my vehicle? In which cases can a policeman invade my privacy WITHOUT my consent? Unfortunately, the answers to these questions are not always clear, so questions are expected. Don't be shy!

Have you been arrested for DWI? Drug charges? Assault? Or any other misdemeanor or felony in the state of Texas? Don't throw in the towel just yet. Any number of issues can arise in your case that can lead to a dismissal. Police don't always follow the proper procedure when making arrests. With DWI's particularly, the courts recognize that breath and blood tests are not completely accurate. The state is required to prove accuracy and proper protocol in each and every case.

With 33 years of experience defending against crimes ranging from DWI to Capital Murder, the attorneys at Mercer & Keirnan are fluent in Texas law. We will exhaust every possible avenue to make sure that the state can prove its case against you. Call us now for a free in-office or over-the-phone evaluation. (713) 236-9700.

Payment plans are available. We pride ourselves in offering affordable legal services to those in need. We believe that all Texans deserve the right to high quality legal represenation, regardless of financial position.
