Affidavit

A formal statement of facts sworn before an officer, usually a Notary Public, authorized by law to administer oaths. As pertains to process servers examples are an Affidavit of Service or an Affidavit of Attempted Service. In the state of Washington affidavits prepared by process servers have been largely replaced by declarations. See RCW 9A.72.085 for specific requirements. See also Proof of Service and Declaration.
