Miss. Code Ann. § 91-7-63: Grant of administration.

(1) Letters of administration shall be granted by the chancery court of the county in which the intestate had, at the time of his death, a fixed place of residence; but if the intestate did not have a fixed place of residence, then by the chancery court of the county where the intestate died, or that in which his personal property or some part of it may be. The court shall grant letters of administration to the relative who may apply, preferring first the husband or wife and then such others as may be next entitled to distribution if not disqualified, selecting amongst those who may stand in equal right the person or persons best calculated to manage the estate; or the court may select a stranger, a trust company organized under the laws of this state, or of a national bank doing business in this state, if the kindred be incompetent. If such person does not apply for administration within thirty (30) days from the death of an intestate, the court may grant administration to a creditor or to any other suitable person.

(2) In addition to the rights and duties of the administrator contained in this chapter, he shall also have those rights, powers and remedies as set forth in Section 91-9-9.
