Washington Sexual Assault Laws


If you are facing allegations related to sexual assault in Washington, the stakes are high. Washington takes these matters seriously, and the law defines sexual offenses broadly. Your freedom, reputation, and future are on the line. You need a strong defense from a Bellevue, WA sex crime defense lawyer to protect your rights and respond effectively—and building a defense begins when you understand the charges you are actually facing. Here is what you need to know about Washington’s sexual assault laws.

How Washington State Defines Sexual Assault

According to WAC 504-26-221, sexual assault is a form of sex-based harassment that happens without the victim’s consent. There are many types of sexual assault, and the law defines these crimes as follows:

(a) Sex offense. Any sexual act directed against another person, without the consent of the complainant, including instances where the complainant is incapable of giving consent.

(b) Rape (except statutory rape). Penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, or by a sex-related object, without the consent of the complainant, including instances where the complainant is incapable of giving consent because of their age or because of their temporary or permanent mental or physical incapacity.

(c) Fondling. The touching of the private body parts of another person for the purpose of sexual gratification, without the consent of the complainant, including instances where the complainant is incapable of giving consent because of their age or because of their temporary or permanent mental or physical incapacity.

(d) Incest. Nonforcible sexual intercourse between persons who are related to each other within the degrees wherein marriage is prohibited by law.

(e) Statutory rape. Nonforcible sexual intercourse with a person who is under the statutory age of consent.

Types of Sexual Assault Crimes Under Washington Law

Washington categorizes sexual assault into several distinct offenses, each carrying different penalties based on the circumstances. Common charges include:

  • Rape in the First Degree (RCW 9A.44.040): A Class A felony involving forcible sexual intercourse with aggravating factors like the use of a weapon, kidnapping, or serious injury
  • Rape in the Second Degree (RCW 9A.44.050): A Class A felony involving forcible intercourse or when the victim is mentally or physically incapacitated
  • Rape in the Third Degree (RCW 9A.44.060): A Class C felony for non-consensual intercourse without forcible compulsion
  • Indecent Liberties (RCW 9A.44.100): A Class B felony for non-consensual sexual contact, including touching for sexual gratification
  • Incest (RCW 9A.64.020): Prohibits sexual intercourse between close blood relatives.

Understanding Consent Under Washington’s Criminal Statutes

In Washington, consent is central to every sexual assault case. Consent must be clear, voluntary, and ongoing. It cannot be assumed from past behavior or a prior relationship. The law emphasizes that consent is an active process; if it is not clearly given, it does not exist.

A person who is asleep, intoxicated, or otherwise incapacitated cannot legally consent. Coercion—such as threats, intimidation, or persistent pressure—also invalidates any prior agreement to sexual activity and can form the basis of a sexual assault charge. Being under the influence of alcohol or drugs does not excuse non-consensual conduct.

What to Do If You’ve Been Accused of Sexual Assault in Washington

If you are facing accusations of sexual assault, remain calm and remain silent. Do not speak to law enforcement without legal representation. Anything you say can be used against you. Avoid contacting the alleged victim, as this could be interpreted as harassment or intimidation.

Most importantly, contact a Bellevue, WA criminal defense attorney as soon as possible. For years, The Law Offices of Mark S. Treyz has defended Washington clients against sexual assault allegations and can help you navigate the legal system with care and precision.
