CHAPTER 44. ADMINISTRATION OF ESTATES AND TRUSTS.
ARTICLE 1. PERSONAL REPRESENTATIVES.
§44-1-2. Administration with will annexed.
If there be no executor appointed by the will, or if all the executors therein named refuse the executorship, or fail when required to give such bond, which shall amount to such refusal, or have died, such court, or clerk thereof during the recess of the regular sessions of such court, may grant administration, with the will annexed, to the person who would have been entitled to administration if there had been no will, and he shall take such oath and give such bond.
§44-1-4. Appointment of administrator.
When a person dies intestate (with no will) the jurisdiction to hear and determine the right of administration of his estate shall be in the county court, or clerk thereof during the recess of the regular sessions of such court, which would have jurisdiction as to the probate of his will, if there were one. Administration shall be granted to the distributees who apply therefor, preferring first the husband or wife, and then such of the others entitled to distribution as such court or clerk shall see fit. If no distributee apply for administration within thirty days from the death of the intestate, such court or clerk may grant administration to one or more of his creditors, or to any other person.
