Wisconsin Notice to Creditors in a United States Foreclosure Action is a formal notice that must be provided to creditors of a debtor who has defaulted on their mortgage payments in the United States. The notice must be sent to all known creditors of the debtor by the lender or the mortgage service. It notifies creditors that a foreclosure action has been initiated and informs them of their right to file a claim for any debt owed to them. It also informs creditors of the deadline by which they must file their claim or else it will be barred from recovery. There are two types of Wisconsin Notice to Creditors in a United States Foreclosure Action: Pre-Foreclosure and Post-Foreclosure. Pre-Foreclosure Notice is sent before the foreclosure sale occurs, and it provides creditors with their right to file a claim. Post-Foreclosure Notice is sent after the foreclosure sale occurs, and it informs creditors that the foreclosure sale has taken place and that any claim filed must be filed within a certain period of time.
