An elderly man named Yorick wants to sell his house and move into a nursing home. He signs a six-month exclusive right-to-sell listing agreement. His agent gets the house cleaned up and helps Yorick move most of his furniture into storage. The agent then arranges for some gardening work, stages the house, and put the property on the market. One week later Yorick dies. Two months after that, and well before the expiration date of the listing agreement, the executor of Yorik's estate sells the house without any help from the listing broker or agent. Is the broker (and consequently, the agent) entitled to a commission?
