An Oregon Affidavit Of Service is a legal document used to certify that a process server has successfully delivered legal documents to a particular party. This type of document is commonly used in the state of Oregon when serving court documents such as summons, complaint, or orders. There are two types of Oregon Affidavit Of Service: an Affidavit Of Service By Personal Service and an Affidavit Of Service By Mail. The Affidavit Of Service By Personal Service is used to certify that the process server hand-delivered the documents directly to the defendant or their representative. The Affidavit Of Service By Mail is used to certify that the process server mailed the documents to the defendant or their representative. In either case, the Oregon Affidavit Of Service must contain the name of the defendant, the date of service, the documents served, and the signature of the process server.
