[Mortuary Blues] Jack and Bianca Had a Partnership Running a Mortuary

[Mortuary Blues] Jack and Bianca had a partnership running a mortuary. Bianca died, and after her death, Jack decided to shut down the mortuary. Jack incurred some expenses in closing the business affairs of the mortuary. He sought compensation for those expenses but Gus, the executor of Bianca's estate, objected. Gus also claimed that Jack had no rights in Bianca's share of the partnership property and that Gus, the executor, had the right to confiscate her share of the property and sell it at auction. Jack, however, took the position that all interests of Bianca passed to Jack and that Jack owed her estate nothing. The articles of partnership did not address death.
