The Wisconsin Affidavit of Efforts to Locate Absent Respondent is a legal document used in Wisconsin family law cases when a party wishes to serve a summons or petition on someone who cannot be located. This affidavit is typically used when the party has made reasonable attempts to locate the respondent, but has been unsuccessful. The affidavit is submitted to the court to prove that due diligence was used in an effort to locate the respondent. The affidavit must include the name of the respondent, any known addresses, the type of service requested, the date the service was attempted, and a description of the efforts made to locate the respondent. There are two types of Wisconsin Affidavit of Efforts to Locate Absent Respondent: the Affidavit of Diligent Search and the Affidavit of Service by Publication. The Affidavit of Diligent Search is used when the petitioner has made reasonable attempts to locate the respondent, but has been unsuccessful. The Affidavit of Service by Publication is used when all efforts to locate the respondent have been exhausted and the petitioner must serve the respondent by publishing a notice in a newspaper.
