Being accused of a crime is serious and can have life-altering effects for both you and your loved ones. After a charge has been brought against you, you’re likely reeling with questions. How am I going to pay the fines for my charge? How will I be able to apply for a job? How will I be able to provide for my family if I’m in prison?

It’s an unfortunate reality that people who have a conviction on their record have even their barest rights stripped away from them and the accused often deal with faltering or failing relationships, even before they ever step into a courtroom. With the help of an experienced attorney, however, it’s possible to have charges dismissed or even reduced. You’re unlikely to acquire the best possible results that you deserve without legal representation, so this step is crucial. People who have a defense attorney are much more likely to have the severity of their punishment reduced or eliminated. For this reason, we always recommend that those who are accused of a crime seek the legal guidance from an experienced and aggressive Dallas criminal defense attorney.

How Long Will the Process Take?

It’s incredibly difficult to say how long you will need to fight an accusation. The longest criminal court case recorded in the United States took seven years, but most processes run through to completion within a few months. Some are shorter, and some are longer than this. Many of the determining factors depend on what crime you were accused of, whether it’s a federal or a state crime, whether it is a felony or a misdemeanor, among other things. It is best to consult with an attorney regarding this question as they will be able to give you a more accurate idea of how long it may take.

Being arrested is one of the scariest and most confusing moments in an individual’s life, especially if it’s the first time it’s happened to you. If you are arrested in Dallas or anywhere else in Texas, you should be careful about what you say when dealing with police officers. If you are being questioned, don’t answer any questions until your attorney is present. Never sign anything without consulting with an experienced criminal defense attorney. If you believe you are being threatened or coerced by law enforcement after your arrest, let your lawyer know about this.

No matter if you have been arrested for a state crime or federal crime, police officers are trained to accomplish their main goal, which is to gather as much evidence as they can. This, it’s critical that you exercise your Fifth Amendment right to remain silent. Immediately ask to speak to a qualified criminal defense lawyer.


The primary difference between a misdemeanor and a felony is that misdemeanors are less serious offenses. Misdemeanors are punishable with less than a year jail time, whereas felonies are punishable with at least a year of prison time.

A misdemeanor charge typically involves non-violent offense, meaning the illegal action did not cause harm to the alleged victim. Punishments for misdemeanor offenses include: fines, community service, court-ordered treatment, probation, and jail time that does not exceed one year.

In Texas, misdemeanors are classified into three categories according to the seriousness of the offense: (1) Class A misdemeanor; (2) Class B misdemeanor; (3) Class C misdemeanor.

In Texas, misdemeanors are classified into three categories according to the seriousness of the offense: (1) Class A misdemeanor; (2) Class B misdemeanor; (3) Class C misdemeanor.

  • Shoplifting and theft
  • Driving While Intoxicated (first and second offense)
  • Indecent exposure
  • Prostitution
  • Harassment
  • Unlawful carrying of a weapon
  • Assault with injury
  • Burglary of a vehicle
  • Failure to pay child support
  • Minor drug possession
  • Lying to a police officer

Class C misdemeanors, the least serious misdemeanor offense, are punishable by fine only. Traffic citations like speeding and driving without a license are among the most common fine-only misdemeanor offenses.

A felony is the most serious type of criminal offense. Crimes in this category are reserved for violent and illegal actions that cause physical injury, financial harm, or death to another person. In addition to a prison sentence of over a year, hefty fines are imposed with felonies. The fine for a felony is usually more than a misdemeanor.

Examples of felonies include:

  • Robbery
  • Arson
  • Kidnapping
  • Indecent exposure to a child
  • Intoxication assault
  • Rape
  • Murder
  • Manslaughter

  • Possession of child pornography
  • Online solicitation of a minor
  • DWI (third offense)
  • Trafficking of persons


If a plea bargain cannot be reached during the pretrial conference, your trial date will be set. In some cases, it is better idea for a defendant to stand trial rather than take a plea bargain. It all depends on the facts and circumstances of the particular case. An experienced criminal defense lawyer will be able to determine your best course of action.

A criminal trial involves opening statements by your defense lawyer and the prosecutor. Witnesses are called and questioned. Evidence is presented. Your criminal defense lawyer and the prosecutor will make closing statements, and the judge will give the jury instructions. After deliberation, the jury announces its guilty or not guilty verdict.

In Texas, the jury’s verdict must be unanimous in order to convict the defendant. If a unanimous vote cannot be reached, a mistrial is declared. If a unanimous guilty vote is reached, sentencing commences. After the verdict has been rendered, your lawyer may attempt a post-trial motion, such as a motion for a new trial.


“He handled an unjust ticket for me and was very thorough and on time with notices, etc. His communication was short and to the point without false fluffy words or promises.”


When my son received a DWI, I wanted to get him THE BEST lawyer I could find. I researched for two days, and then I found Mark Lassiter. I looked no further. As soon as I read about him, I knew that I found THE BEST. From the moment I met him, I had COMPLETE confidence in him. At the end of my son's trial, Mr. Lassiter came through with a defense case so impressive that the case was dismissed before the prosecutors finished their argument. I will always be grateful to him.


Mark is a very intelligent professional defense Attorney on my DWI offense that Mark convinced the jury that i wasn't guilty i highy recommend Mark to my family and friends once again thanks Mark


I had my first DWI charge and I was unclear of next steps. I was getting propositioned left and right by less ethical lawyers and one even "claimed" my case and I missed my court date. However, Mark Lassiter and his amazing paralegal took care of everything. They were very prompt and clear with their communication on every step of the process. Also if anything came up I got a call right away and they let me know what I needed to do next. Honestly made this stressful situation manageable. I already recommend them to anyone who is going through the same situation as me. That said he does come at a premium cost but is worth every penny, and his team is willing to work with you on payment plans.


I recently was referred to contact Mark Lassiter by a colleague and called him for a consultation related to a recent arrest for public intoxication in Dallas. He was terrific; I had never been arrested before and was unsure of what the appropriate next steps would be. He was detailed in his step-by-step approach and provided me sound legal advice on how he would handle this case.I elected to hire him as my attorney and it was the best decision. He handled my case and was able to get the charges dismissed. As a professional it was imperative to be able to get this charge removed from my record.If you are in need of a criminal defense attorney, I would highly recommend Mark's services.


I am a very satisfied and a relived client. After meeting with various lawyers Mark was the one who won me over. Walking into his office you will be impressed of all his credentials. He is professional and aggressive which is what everyone looks for in a attorney. Every other lawyer I interviewed mentioned to "plea deal", I knew that meant settling. A DWI on my record was the LAST thing I wanted. I was very hopeless and scared (considering it was my first offense) but Mark always reassured me that I had a very good case. Ultimately, Mark did a phenomenal job in the court room (he had the prosecutors speechless), which resulted in a dismissal. I recommend this man to everyone I know. Thank you Mark, I owe you my life.
