2. Betsy's elderly father made Betsy his agent by giving her written authority to sell his house. Her father lived in Arizona and she lived in Minnesota. After about two months she found a buyer for the house and signed an acceptance of the offer on March 21. Later that same day she learned her father had died the day before (March 20). Betsy's brothers and sisters did not want their father's house sold and claimed that the acceptance Betsy signed was void. The buyer of the house claims Betsy had the legal authority to sell the house and that the contract is binding. Who is right? Why?
