About Mark

Learn Mark’s areas of practice.


The Law Office of Mark Knapp has been in business across the State of Washington from Seattle to Spokane and beyond for almost 30 years. Our clients are working people that need to know their rights pertaining to NFA Gun Trusts, employment discrimination, criminal defense and how to deal with various issues involving possession and use of firearms.

We encourage anyone in the State of Washington to call regarding criminal charges or issues of self-defense and Constitutional rights. We are dedicated to identifying legal issues related to the needs of individuals and to provide appropriate legal advice where needed. I am only licensed in the State of Washington so any legal advice will relate to Washington law or federal matters even though there may be information of a more general nature on the site regarding the Second Amendment right to keep and bear arms.

We encourage you to make an appointment via e-mail or by calling. Use the blog to get general legal questions answered. If you need an NFA trust we provide high quality trusts and have an experienced team that will help you with every aspect of completing your gun trust and making it remain successful over the years.

very helpful and supportive
Mr.Knapp was very helpful and supportive clearing my politically motivated ERPO. We exchanged many emails and successfully avoided more court efforts. I had sent a harsh email criticizing some local politicians and they responded by taking my guns. In the past these kinds of politiicans were tar and feathered and run out of town or worse. Thanks again.

Gun Rights Restored
Mr Knapp did exactly what he told me he would do, and when he told me he would do it. His services enable me to hunt with my grandchildren again and are greatly appreciated. I would recommend him to anybody looking to have their rights restored.

Estate Issues
Mark was referred to us by the NRA, and was an immense help in resolving issues with firearms that had been passed down to us because of death in the family. I would utilize his services without hesitation again, and, have recommended him to others in my area. He is knowledgeable, friendly, and a pleasure to work with.

Hardworking, fast, and helpful.
As a federal police officer I had difficulty getting quality legal advice on complex situations and policies. Mark was there for my team, he gave excellent advice and legal guidance at a very reasonable price. We are sincerely grateful for his help.

Firearms Lawyer, Mark S Knapp
Mr. Knapp got my firearm rights restored very quickly. Another attorney told me it could not be done. Most of the business was completed online I did not have to attend court. I would and have recommended Mark Knapp to friends.

Mark Knapp, an excellent firearms advocate for Washington State/ by Byron Barton
Mark Knapp, has established a reputation as an excellent firearms advocate for Washington State. He is knowledgeable in state and federal firearms laws which have allowed him to protect his clients. He has represented me personally from the Federal Dist Ct to the 9th Cir Ct of Appeals. I personally have ten years of Para Legal research experience. Having worked with Mark, I understand how important America’s civil and constitutionals rights are. These are the reasons I hired Mark, a professional firearms attorney. Mark has the ability to effectively settle cases with BATF, FBI and prosecuting attorneys before trial, which is priceless. His experience and knowledge allows him to aggressively attack the prosecutors claims when his clients are charged with weapons violations. The federal government has the power and unlimited money to bring tremendous resources against you when facing potential state and federal firearm charges. Protecting your Constitutional Rights is a MUST. Byron B
