Had the flip side of this happen when a neighbor sold his farm. 200 acres m/l sold at auction in 4 or 5 tracts. Old geezer from the city came to the auction and bought every tract. Bid $4K to $5K per acre when most local farms were lucky to bring half that per acre. Auction was on a Saturday. Early following week, found out the guy had been committed to a mental institution. Turns out the guy was spending HIS WIFE'S money to buy the property. When she found out how much, she said NO. Given that all of the auction documents were properly executed legal contracts, she had him placed in a mental institution as "crazy. not competent to transact legal business" to avoid being forced to honor the contracts and pay up in court.
