Washington Proof of Personal Service is a legal process through which service of process is documented in the state of Washington. This process is used to provide proof of service of legal documents, such as summons, complaints, motions, and other court documents, to parties involved in a legal dispute. The most common types of Washington Proof of Personal Service are: 1. Waiver of Service: The Waiver of Service is a form that allows a party to waive their right to be served with the legal documents. The Waiver of Service must be signed by the person who is being served, and the signature must be witnessed by a third party. 2. Personal Service: This is the most common form of service of process. A process server will serve the documents to the party being served in person. 3. Substituted Service: Substituted service is used when personal service is not possible. The documents must be served to someone of suitable age and discretion at the defendant’s residence or place of business. 4. Mail Service: Mail service is used when the defendant is outside the state or cannot be found. The documents must be sent to the defendant by certified mail with a return receipt requested. Once the documents have been served, the process server must complete an Affidavit of Service, which is a sworn statement that the documents have been served according to Washington law. The Affidavit must then be filed with the court.
