Jacob lay on his deathbed, thinking about his sons.  He knew that they did not get along well.  He did not want them to argue after his death about his real property, Blackacre, which he owned in fee simple absolute. Jacob decided to structure his Last Will and Testament in a way that would help his children learn to cooperate.  The will Jacob executed read as follows: “I hereby devise Blackacre to my four beloved sons Reuben, Gad, Dan, and Benjamin equally, as joint tenants, not as tenants in common, with the hope that they will live in peace and harmony all of their days on our family’s land.”   At Jacob’s death, Reuben (without his brothers’ advance knowledge or agreement) immediately mortgaged his interest in the property and used the money to buy a condo in the Bahamas where he lived most of the year.   Gad, Dan, and Benjamin continued living on Blackacre and tried to get along.  After a few years, Gad moved to Los Angeles to attempt to break into the movie business.  Before he left, he gave his interest in Blackacre to Dan’s son, Evan, in a deed that read “To Evan, for so long as he makes his full-time residence on Blackacre.” Several years later, Reuben died intestate, leaving his son Samuel as his only heir. What is the state of the title at this point?   Tip:  Structure your answer by following the chronological timeline of transfers, remembering to stay in IRAC.
