The Washington Waiver of Service of Summons is a legal document that allows a defendant in a civil lawsuit to avoid being served with a summons in person, thus avoiding the need to appear in court for a hearing or trial. The waiver must be signed by the defendant and witnessed by a notary public. There are two types of Washington Waiver of Service of Summons: a general waiver and a special waiver. The general waiver applies to all civil lawsuits in Washington State, while the special waiver applies only to certain types of civil lawsuits, such as those involving family law or probate. Both waivers must be filed with the court in order to be legally valid.
