02 / HOW JOHN CAN HELP
A DWI matter can involve both a criminal case and questions about your driver’s license. Bring the paperwork you received and discuss deadlines promptly so the different parts of the matter can be considered.
The charge, the circumstances of the encounter, and the evidence all matter. John can review the allegations and discuss how the facts and applicable law affect the available defense options.
An assault allegation deserves a careful review of the surrounding circumstances. Bring any court orders and tell the office about release conditions or upcoming hearings. Follow existing orders while seeking advice.
The stakes in a felony case make preparation essential. Understand the allegations, the court schedule, and the decisions ahead before choosing a course of action.
A family violence allegation can affect custody, housing, and firearm rights before the case is ever resolved. Follow any protective order you have been given and tell the office about the conditions you are under.
Federal cases run on different rules, timelines, and sentencing exposure than state court. If a federal agency has contacted you, or you have been charged in federal court, say so on the first call.
A juvenile matter follows its own procedure and can reach school and future opportunities. Parents should ask early what the process involves and which decisions are coming.
An old charge can still surface in background checks, including one that never led to a conviction. John can look at whether a record is eligible for expunction or an order of nondisclosure.
Wonderful service!Miranda Barela
Having been exposed to lawyers in a variety of fields, I was so pleased by the representation provided by John. Not only could he explain the strengths and weaknesses of my case from a merits standpoint, he was very familiar with the judge and the court clerks. These two factors combined allowed him to advise me on the potential benefits and risks of litigation from a very practical standpoint. Just an awesome experience.Richard Brown

My son had some legal matters facing him and it had our family quite worried. John was so professional and caring and took time to explain what was happening through every step of the way. He worked very hard for my son and was able to get an outcome that was more than agreeable. This was not the first time I have had to use an attorney, but it was the first time I was truly impressed by the dedication, hard work and compassion showed by a man in his field of work. He is an amazing attorney, and I would recommend him without hesitation. I truly thank him for being the person he is. L.M.Luann Mosley
I highly recommend John Nix and hands down the best attorney you can get! I came to trust Mr. Nix very quickly, and that is very important when you hire an attorney to represent you in any legal matter. John never made me feel that my case wasn't worth his time! If I had additional questions or concerns, I never felt like I was "bothering" him or his staff with phone calls, they always responded in a professional and timely matter. In my situation, Mr. Nix helped me the first moment I contacted his office, he listened and understood my situation and then had the experience and knowledge of the system to help me, then he quickly started working on my case as my representative and he wanted what was right and fought to get what belonged to me. If you are looking for a great attorney that not only works for YOU but with you, John Nix and his team is what you need! I will forever be grateful to have came across Mr. Nix and his team who proved thru actions how my case mattered and resolved it in a timely matter.

John is an amazing attorney, and even better person! He has represented my family and I with the utmost professionalism, and has never failed us. We appreciate this man beyond anything words could express! Thank you John!Christal Ingram
There have been two attorneys I hold with the highest of regard. The first was a man who helped my mother when a doctor wrongfully caused the death of my father when I was nine. The second is John Nix. I have utilized him as an attorney to represent our family. I have seen how he is as a man, a father, a human being. John, doesn't treat you like you are less than. He cares and he wants you to do better; To be the best version of yourself. He fights for those who can't find anyone to stand up for them. Other attorneys I have seen don't care about the person, but John treats you like family. I wouldn't have any one represent myself or my family other than him. He represents truth, fairness, and justice. He is one of a kind. Rare amongst his field. If you want the BEST and only the BEST then reach out to him. I'm proud to know him, and am forever grateful for the man he is.Serrina Janine
John was personable, professional and an excellent listener. His office staff (Tina) and Lola on the phones were top shelf. John's courtroom demeanor was defferential but highly representative of our position. I would gladly recommend him to any and all future clients.Sam Griffin

03 / YOUR QUESTIONS
Practical answers about criminal defense.
The fee depends on the charge, the complexity of the case, and the work involved, and we explain it before representation begins. Clients have access to financing and payment options through LawPay, and the office accepts major credit cards. What affects the cost →
Ask about experience with your type of charge and the court involved, who will actually handle the case, how communication works, how the fee is structured, and about trial experience even if you hope to avoid trial. The full list of questions →
As soon as you know you are facing a charge or need advice about an investigation. Tell the office whether you are in custody, have a hearing approaching, or have received paperwork with a deadline.
DWI is among the firm’s criminal defense practice areas. Call with the county, charge, and dates on your paperwork so the office can confirm availability and whether John can take your matter.
Not every case goes to trial. The appropriate course depends on the evidence, the law, and the choices available in your case. An attorney can explain the implications of a proposed resolution as well as the issues involved in going to trial.
No. A responsible assessment starts with the actual facts and evidence. John can discuss the strengths, concerns, and options in your case, but no attorney can guarantee a dismissal or other outcome.
Yes. Federal matters follow their own procedures, timelines, and sentencing rules, and they are heard in federal court rather than at the Grayson County courthouse. Mention it at the first call so the conversation starts in the right place.
Juvenile matters run on a separate procedure and can affect school and later opportunities. Bring any paperwork you received and the date of the next setting, and ask what decisions are ahead and who makes them.
Sometimes. Eligibility for an expunction or an order of nondisclosure depends on the offense, how the case ended, and how much time has passed, and the rules differ between Texas and Oklahoma. Bring what you know about the charge and the outcome so the office can tell you what to check.
Criminal defense case consultations are free. Fees for representation depend on the charge and the work involved. Ask the office about the proposed scope of representation and payment arrangements before making a commitment.
General information only. Advice and deadlines depend on your situation.
