If a person dies without a will and such person is under a legal disability and has had a guardian, conservator or other fiduciary appointed, then the judge or clerk of such court, upon proof of death of such person, may issue letters of administration to the already acting fiduciary.

Some relative or other person entitled to administer the estate may within thirty days after the death of such person apply to the court for such administration, in which case if appointed will be the person to act for the estate.

If an existing fiduciary is appointed, he or she shall publish notice to creditors and administer the decedent’s estate in the manner required by law.
