Williamson, her mortgage in default, was threatened with foreclosure on her home. She decided to sell the house. The Matthewses learned of this and contacted her about the matter. Williamson claims that she offered to sell her equity for $17,000 and that the Matthewses agreed to pay off the mortgage. The Matthewses contend that the asking price was $1,700. On September 27, the parties signed a contract of sale, which stated the purchase price to be $1,800 (an increase of $100 to account for furniture in the house) plus the unpaid balance of the mortgage. The parties met again on October 10 to sign the deed. Later that day, Williamson, concerned that she had not received her full $17,000 consideration, contacted an attorney. Can Williamson set aside the sale based upon inadequate consideration and mental weakness due to intoxication?
