A more thorough explanation:

Definition: An administrator de bonis non is a person appointed by a court to replace an administrator of a will who can no longer fulfill their duties. This new administrator takes on all the legal responsibilities of the role in order to complete the administration of the will.

For example, if the original administrator of a will passes away or becomes incapacitated, an administrator de bonis non may be appointed by the court to take over their duties. This new administrator would be responsible for managing the assets of the estate, paying off any debts or taxes owed, and distributing the remaining assets to the beneficiaries named in the will.

Another example would be if the original administrator of a will resigns or is removed from their position. In this case, an administrator de bonis non may be appointed to take over their duties and ensure that the administration of the will is completed properly.
