If the family farm is going to be forclosed on how long before the family will be evicted?

Are you sure that foreclosure is in the works? You should speak with an attorney, they may be able to assist. You can contact the Wisconsin Bar Association for guidance: http://www.wisbar.org/

A foreclosure normally takes 90 days. After that the house will almost certainly be resold by whoever tokk it in foreclosure. That will take time. Eviction proceedings can take another 4-6 weeks. If nothing has started yet I'd say you are looking at 6 months. You should confirm my estimate with a WI lawyer.
