Where We Practice

Harris County and nearby courts

A criminal case is heard where it was filed, not where you live. That is why the county matters more than the city: the prosecutors, the bond practice, and the diversion programs are different in each one.

Houston Criminal Defense FAQ

Frequently Asked Questions

Criminal charges raise immediate questions about what to do, when to contact a lawyer, what representation may cost, and what happens next. These answers provide general information about working with Your Houston Criminal Lawyers and the criminal-defense process in Houston and surrounding Texas courts.

What should I do after being arrested or accused of a crime?

Take the accusation seriously and be careful about what you say. Do not lie, destroy evidence, contact witnesses in an attempt to influence them, or discuss the facts of the case on social media. If police want to question you about a criminal matter, you can ask to speak with an attorney before answering questions about the allegations.

Follow any bond conditions, protective orders, no-contact requirements, or court orders that apply to you. Preserve documents, messages, photographs, videos, names of witnesses, and other information that may be relevant to the case. Contacting a criminal defense attorney early gives the lawyer more time to evaluate the allegations and available evidence.

When should I hire a criminal defense attorney?

You should consider contacting a criminal defense attorney as soon as you learn that you are under investigation, have been arrested, receive a court date, discover that a warrant may exist, or believe criminal charges could be filed.

A lawyer may be able to evaluate the situation before important interviews, court settings, evidence issues, or deadlines occur. You do not necessarily have to wait until a case reaches trial — many important decisions happen much earlier in the criminal process.

What criminal charges does Your Houston Criminal Lawyers handle?

Your Houston Criminal Lawyers represents people facing misdemeanor and felony criminal charges, including murder and capital murder, assault, family violence and domestic assault, DWI and DUI, drug and narcotics offenses, robbery, burglary, theft, juvenile matters, and other serious criminal cases.

Visit the Criminal Defense Practice Areas page to find the section that matches the charge or allegation you are facing.

Which Houston-area counties and courts does the firm serve?

The firm represents clients in Houston and criminal courts throughout the Greater Houston area, including matters filed in Harris, Montgomery, Fort Bend, Galveston, and Brazoria Counties, as well as other nearby jurisdictions when appropriate.

The county of filing matters because the courthouse, prosecutors, procedures, available programs, bond practices, and local court procedures can differ by jurisdiction. Visit Counties & Courts We Serve for courthouse and location information.

How much does a criminal defense lawyer cost in Houston?

There is no single standard fee for a criminal defense case. The cost can depend on the charge, complexity of the evidence, stage of the case, expected court work, whether experts or investigators are needed, and whether the matter proceeds toward a jury trial.

Your Houston Criminal Lawyers offers a free initial consultation, so there is no charge simply to contact the firm initially and discuss what you are facing. If representation is offered, the fee arrangement should be explained before you decide whether to hire the firm.

What is the difference between a criminal lawyer and a criminal defense attorney?

“Criminal lawyer” is a broad term for a lawyer who practices criminal law, while a criminal defense attorney represents people accused of or investigated for crimes.

Prosecutors also practice criminal law, but they represent the government. Criminal defense lawyers represent the accused. Sam R. Cammack III has experience on both sides: he previously served as a felony prosecutor and now represents people facing criminal charges.

What should I look for when choosing a criminal defense lawyer in Houston?

Look at the lawyer's criminal-defense experience, relevant jury-trial experience, familiarity with the type of charge, who will actually handle the case, communication practices, and how fees are explained. For a serious felony, experience handling serious felony cases is particularly relevant.

Be cautious about anyone who guarantees a particular result before fully reviewing the evidence. You can also verify a Texas lawyer's licensing history and professional record through the State Bar of Texas. Learn more about Sam R. Cammack III's background and review selected case results.

Will I be able to speak directly with Sam Cammack about my case?

Yes. The office is structured around direct attorney involvement. Sam R. Cammack III leads the legal strategy, reviews the State's evidence, advises clients, negotiates when appropriate, prepares cases for trial, and represents clients in court.

Holly A. Quinterro, the firm's Office Manager and Legal Assistant, coordinates communication, scheduling, filings, case materials, and client support under Sam's direction. Learn more about the firm and legal team.

How does Sam Cammack's experience as a former prosecutor help the defense?

Before focusing on criminal defense, Sam served as a felony prosecutor in Harrison County, Texas. That experience gave him firsthand exposure to how prosecutors evaluate evidence, prepare witnesses, develop criminal cases, and present felony prosecutions.

In defense practice, that background can help him examine the prosecution's theory from both perspectives, identify evidentiary issues, prepare the defense, evaluate negotiations, and prepare serious cases for trial when necessary. Read Sam Cammack's biography.

Does every criminal case go to a jury trial?

No. Criminal cases can end in many different ways depending on the charge, evidence, jurisdiction, procedural history, available legal issues, and decisions made by the client after receiving legal advice.

Depending on the circumstances, a case may involve dismissal, a grand-jury no-bill, reduction of charges, negotiated resolution, diversion or other pretrial disposition where available, mistrial, acquittal, or conviction after trial. The appropriate strategy depends on the individual case.

Can I review Sam Cammack's previous criminal defense case results?

Yes. The firm's Case Results page documents selected dismissals, no-bills, jury-trial outcomes, and serious felony matters, including independently reported cases.

The examples are provided to show the kinds of cases and courtroom work involved in Sam's practice — not to predict what will happen in another person's case. Review Houston Criminal Defense Case Results. Past results do not guarantee a similar outcome.

How do I get started if I need a criminal defense lawyer?

Call 713-224-4444 or use the firm's contact page to request a free initial consultation.

If you have them, be ready with the defendant's name, the charge, county, court or cause number, upcoming court date, bond information, and any papers you received. You do not need to have every document before calling — basic information is enough to begin the conversation.

These answers provide general information and are not legal advice. Criminal cases depend on their individual facts, evidence, charges, jurisdiction, and procedural history. Reading this page, calling the office, or submitting a consultation request does not by itself create an attorney-client relationship. Representation begins only after the firm and client enter into an appropriate written agreement.
