Oregon Declaration of Proof of Service is a document used in the state of Oregon to show that a particular document has been served to its intended recipient. The document is used to prove that the document was delivered to the person or entity listed on the document, and that the service was made in accordance with Oregon law. There are three types of Oregon Declaration of Proof of Service: personal service, substituted service, and service by mail. Personal service is when a copy of the document is handed directly to the recipient. Substituted service is when a copy of the document is delivered to someone other than the recipient, such as an adult family member or an employee at the recipient's place of business. Service by mail is when a copy of the document is sent through the mail to the recipient's last known address. The Oregon Declaration of Proof of Service must be filled out and signed by the individual who served the document, and must include the date and method of service. It must also include a statement that the document was served in accordance with Oregon law.
