§ 2-2-110 — When judge disqualified; exception

When the judge before whom probate matters are brought is
interested as next of kin to the decedent, or as the legatee or
devisee under the will, or has any other interest in the outcome
of, or concerning the matters brought before him, he shall call
in some other district judge to hear and determine all such
matters. Being a witness to a will does not itself disqualify a
district judge, after the will has been probated, from hearing
any matters concerning the will or the estate being probated
except matters relating to the admission of the will to probate
and contests thereon, and the granting of letters testamentary
or of administration thereunder.
