The Oregon Certificate of Service Of Summons is a document that is used to certify that a defendant in a legal case has been properly served with a summons. It is typically completed and signed by the person who served the summons. There are two main types of Oregon Certificate of Service Of Summons: Personal Service and Substitute Service. Personal Service is when the summons is served directly to the defendant by someone who is not a party to the action. Substitute Service is when the summons is served to someone related to or associated with the defendant, or to someone responsible for accepting service on the defendant's behalf. The Certificate of Service must include the date, time and place where the service was made, the name of the person served, the name of the person who served the summons, and the manner in which the summons was served.
