I defend persons accused of assaults of an especially sensitive nature—sexual assault, child abuse, and domestic violence.
This has been the focus of my work since 1996. I've obtained many trial victories and many victories without trial for those accused of these assaults. I've also lectured and written extensively on legal issues relating to child abuse and sexual assault, and I've served on child abuse task forces appointed by government leaders.
While most of my work is in Washington state, I've also handled cases in other states and am glad to go where I am needed.
I've practiced law since 1981, first as a prosecutor, and since 1984 in private practice. I've been recognized several times as a "Super Lawyer" by Washington Law & Politics magazine.

I want to thank David for his time, guidance, and expertise with my case. His thoroughness, professionalism, and clear advice made a very stressful situation much easier to navigate, and I appreciate the effort that he put into my case. I’m very grateful for his help.

Mr. Marshall is beyond excellent. He helped my family and I squash a civil case that threatened to ruin my career among other things. He was consistently ahead of anything coming and I was never surprised. He is worth every dime.
This client needed a lot of patience. We could not make things happen as quickly as we wanted to, but eventually we got the right result. I was glad for the privilege of representing this person and for the satisfaction of succeeding for them.

It was great to work with Mike on his defense. He asked excellent questions, keeping us on our toes! I'm glad we were able to put the claims against him in his rear-view mirror.

I retained David Marshall and his firm after my previous attorney retired. In all ways did I find David to be caring, competent, and extremely thorough. David and his team are absolutely top-tier and I can highly recommend them.
It was a great pleasure to get to know this delightful person in the course of serving them.
"I recommended attorney David Stanley Marshall of The Marshall Defense Firm to a prominent professional client facing significant allegations of domestic violence, sexual assault, and potential child abuse. Based on the seriousness of the accusations leveled against my client in multiple separate but related civil cases, I wanted to recommend a specialty defense firm for any related criminal work. I am so glad I did, as my personal interactions with Mr. Marshall and his Firm matched the positive experience reported back to me by my client. Overall, Mr. Marshall and his Firm conducted themselves with the upmost professionalism and were truly a pleasure to work with. I would strongly recommend Mr. Marshall and his team again."
"I refer individuals facing serious charges, to this firm because I have the highest of confidence in their ability to defend the person. They are prepared to come along side, in the darkest of times and be an advocate in very difficult cases."
"I endorse this lawyer. Mr. Marshall and I have represented mutual clients. I have always been extremely impressed with his knowledge and his intense passion in representing his clients. He is preeminent in his field. David has earned my complete trust and I can recommend him and his firm without any hesitation whatsoever."
"In my prior career as a Senior Deputy Prosecuting Attorney in the specialty area of child sexual and physical abuse, I had the opportunity to work opposite David. He was without a doubt among the best prepared defense attorneys I went up against. While it is important to hire an attorney that will fight hard for you, fight is not enough. The fight must be smart, focused, respectful, and persuasive. David's fight is each of these things. I would highly recommend him to anyone in need of a child abuse or sex crimes defense attorney in greater Seattle."
"I heartily endorse David. I referred a good client of mine to him. The matter was quite complex in that it required an understanding of my client and his deficits and of our unique community. David did an outstanding job, not only understanding them but used them to obtain an excellent job for my client. I would not hesitate to refer to him again."
"I met David Marshall at the National Child Abuse Defense Conference in Las Vegas several years ago. David and I were about to begin work on a sex abuse case together, and he was also attending the conference. I learned that he didn’t just attend the conference; more than once he has been on the faculty. The case went to trial twice, and gave me an excellent view of David’s approach, preparation, and skills. From the beginning he was careful and thorough. He looked at the case from every angle, and his preparation was meticulous. In court David was excellent. Working with him was much like taking a class; I found myself taking notes on approaches and tactics I wanted to use myself. At all times he was professional and a gentleman."
"David is a brilliant attorney. He stands out because of his excellent work ethic and mastery of the law. Above all, David is a special attorney because he cares deeply about his clients and is prepared, ready, and able to fight for their cause. In numerous occasions, I have had the privilege and the honor to see David prepare for his cases during focus group sessions with a team of skilled trial lawyers. He has and continues to impress me with his high standards and resolve to battle for his clients. David is the kind of person and attorney I want on my side."
"I heartily endorse this lawyer's work. David and I have worked together on several cases in recent years and I have been very impressed with his diligence, intelligence, thoroughness and professionalism. He is one of the leading criminal defense lawyers in the Seattle area when it comes to the defense of serious cases of child sexual abuse."
"I endorse this lawyer's work. I have had the pleasure of consulting with David on various cases over the last 15 years. He is a gifted, hard working lawyer who is constantly improving his practice to benefit his clients. He stays current on the law in an area that is constantly changing. He is at the forefront of new ideas and methods. In addition to his legal accumen, he is kind, thoughtful and a good human being."
"I endorse this lawyer's work. In 2005, I was the chair of a continuing legal education program sponsored by the Washington Association for Criminal Defense Lawyers. I selected David Marshall to speak on the recent changes to the Special Sexual Offender Sentencing Alternative because he was recognized as a noted authority on sexual offenses. Unlike some of the other speakers, David showed up with an organized, well-prepared talk. He received high ratings from the lawyers who attended the program."
"I endorse this lawyer's work. I have observed and conferred with David Marshall regarding his cases and trial preparation, and have seen the long hours, focus, resources and intensity he brings to representing each client. "
