The Illinois Affidavit of Service By Publication is a legal document used to prove that a notice or document was served to a party in a legal proceeding by publishing it in a newspaper. The purpose of publishing the notice is to let the party know that the legal process has begun and that they must take action. This type of service is used when a party cannot be found or when they refuse to accept service via other means. There are two types of Illinois Affidavit of Service By Publication: Standard and Constructive. The Standard Affidavit of Service By Publication is used when a party to a legal proceeding cannot be located. It involves publishing the notice in a newspaper of general circulation in the county where the legal proceeding is taking place. The Constructive Affidavit of Service By Publication is used when the party to the legal proceeding refuses to accept service by other means. It involves publishing the notice in two newspapers of general circulation in the county where the legal proceeding is taking place. Both types of Affidavit of Service By Publication must be completed and signed by the person who published the notice. The Affidavit must include the name of the newspaper where the notice was published, the date of publication, the name of the party being served, the type of notice served, and the name of the person who published the notice. It must also be signed by a witness. After the Affidavit of Service By Publication is completed, it must be filed in the county court where the legal proceeding is taking place.
