The answer seems like it should be logical, but sometimes, logic and law may not go hand in hand. The relevant clause reads:
Who is the executor?
- I appoint my husband, X, and my son Y to be my executors
- If my son Y refuses, is unable or unwilling to act or continue to act as my executor, I appoint in his place my daughter Z.
Who is the executor?
- Does Y become sole executor?
- Or since the appointment was joint (X and Y), and X has died, does clause 1 fail, and therefore clause 2 applies, and Z becomes sole executor.
- Or does the executor of the husband, X, come into play?
