The Will: Catherine already receives $10,000 yearly from her mother's estate, and by default she is going at get an additional $30,000 after her father's death. Dr. Sloper already considers Catherine an Inadequate Inheritor, and makes it very clear to her that he will change his will to completely disinherit her and donate his money to various organizations after his death. He ends up doing it, too... which is why Morris breaks it off with Catherine.
