1.Lynn and Jack jointly own shares of stock of a corporation, have a joint bank account, and have purchased and own as tenants in common a piece of real estate. They share equally the dividends paid on the stock, the interest on the bank account, and the rent from the real estate.

Samuel sues Lynn and Jack for his personal injuries, joining Lynn as defendant on the theory that Lynn was Jack's partner. Is Lynn liable as a partner of Jack?

2.Merlin Winters had three sons.  Merlin and his youngest son, Abraham, had a falling out in 1998 and never spoke to each other again.  Merlin made a formal will in 2000, leaving all of his property to his two older sons and deliberately excluding Abraham.  Merlin's health began to deteriorate, and by 2001 he was under the full-time care of a nurse, Julia.  In 2002 he made a new will expressly revoking the 2000 will and leaving all his property to Julia.  On Merlin's death, the two older sons contested the 2002 will, claiming that Julia had exercised undue influence over their father.  Abraham claimed that both wills were invalid.  He contended that the first will had been revoked by the second will and that the second will was invalid on the ground of undue influence.  Is Abraham's contention correct?  Explain.
