What the Affidavit of Mailing for Waukesha County Is

The Affidavit of Mailing for Waukesha County is a sworn written statement confirming that specified documents or notices were mailed to designated recipients on a stated date. It is commonly used to document service by mail for property tax notices, foreclosure or lien-related correspondence, administrative hearings, and other official mailings where proof of delivery is required. The affidavit identifies sender and recipient, describes the items mailed, states the mailing method and date, and is signed under penalty of perjury before a notary public or other authorized official.

Why a Proper Affidavit of Mailing Matters
