Minnesota law does not require all foreclosures to be filed through the court system so Minnesota doesn't have a list like counties in North Dakota and some other states.
In Minnesota a document called a Sheriff's Certificate, sometimes referred to as a foreclosure, can be recorded. This document is recorded after the sale takes place through the Sheriff's Office. In most cases the document will state the length of redemption period, which usually runs 5 weeks to 1 year.
Foreclosure information is often published in the legal section of the newspapers. The Clay County Sheriff's Office publishes a calendar of scheduled foreclosure sales.
