As of November 1, 2023, most juveniles will no longer have to register as a sex offender and be eligible to seal their convictions. Law enforcement will start removing eligible people from the registry soon and mailing letters confirming they have been removed. If you receive a letter indicating that you have been removed from the registry, please contact our office for a consultation to determine if you are eligible to seal your offense.

Amy Muth represents individuals charged with sex offenses and other serious crimes throughout Washington state and federal courts. Her advocacy for people charged with sex offenses has led to recognition from her peers. She is a Past President of the Washington Association of Criminal Defense Lawyers, past recipient of the Washington Defender Association's President's Award and has been recognized for many years as a Super Lawyer by Washington Law & Politics. Amy is actively involved in legislative reform for people accused of sex offenses. She writes articles and amicus briefs for WACDL and WDA on sex crime issues. She has lectured to lawyers throughout Washington on how to try these challenging cases, and was a featured speaker at the National Association of Criminal Defense Lawyers sex offenses CLE program. Amy also serves on the Legal Committee for ACLU-WA, and writes amicus briefs on behalf of ACLU-WA on juvenile sexual offending issues.

Amy has practiced law in Washington State since 2001, following graduation from Ohio State University College of Law. She graduated summa cum laude from Ohio Wesleyan University in 1997. She is admitted to practice law in the State of Washington, the United States District Court for the Western District of Washington, and the Ninth Circuit Court of Appeals.

A highly skilled and experienced trial lawyer, Amy has tried numerous criminal cases throughout Western Washington. Amy's finely honed, aggressive litigation skills have led to significant case reductions, dismissals, and acquittals. Her practice emphasizes the defense of complex criminal matters, including:

• Adult and Child Sexual Assault
• Domestic Violence Offenses
• Violent Crimes and other complex matters in state and federal courts 

Because of a better understanding of adolescent and juvenile brain development, courts are now required to consider the role that a young adult’s youthfulness played in the offense conduct. Amy and our team take a particular interest in those cases and are skilled in working with experts to develop mitigation for clients aged 18-25, roughly, who are accused of these offenses.
