Ody, owner of Profitacre, executed an instrument in the proper form of a deed, purporting to convey Profitacre "to Leon for life, then to Ralph in fee simple." Leon, who is Ody's brother and Ralph's father, promptly began to manage Profitacre, which is valuable income-producing real estate. Leon collected all rents and paid all expenses, including real estate taxes. Ralph did not object, and this state of affairs continued for five years until 1987. In that year, Leon executed an instrument in the proper form of a deed, purporting to convey Profitacre to Mona. Ralph, no admirer of Mona, asserted his right to ownership of Profitacre. Mona asserted her ownership and said that if Ralph had any rights he was obligated to pay real estate taxes, even though Leon had been kind enough to pay them in the past. Income from Profitacre is ample to cover expenses, including real estate taxes. In an appropriate action to determine the rights of the parties, the court should decide 
Leon's purported deed forfeited his life estate, so Ralph owns Profitacre in fee simple.  Mona owns an estate for her life, is entitled to all income, and must pay real estate taxes; Ralph owns the remainder interest.  Mona owns an estate for the life of Leon, is entitled to all income, and must pay real estate taxes; Ralph owns the remainder interest.  Mona owns an estate for the life of Leon and is entitled to all income; Ralph owns the remainder interest, and must pay real estate taxes.
