What if your father is the sole executor of a will his father left and you would like to know if he dies can your mother become the sole executor?
Alternate ExecutorsThis will depend on the Probate [sometimes called "Succession"] law of the state in which the deceased [who assigned your father as executor] lived, and thus the will was probated.Usually, the will for which your father was named executor will have a statement naming an alternate (s) executor in the event the named executor [your father in this case] is unable, for any reason, or unwilling to serve in that capacity.If there was no provision for appointing an alternate executor then the Probate law of the state in which the deceased lived will determine the assignment of a new executor.In this type of situation, it would not be uncommon for your mother to be named by the Probate Court as the replacement executor [called an "executrix" in the case of a female].
