RULE 5.120. ADMINISTRATOR AD LITEM
AND GUARDIAN AD LITEM
(a) Appointment. When it is necessary that the
estate of a decedent or a ward be represented in any
probate or guardianship proceeding and there is no
personal representative of the estate or guardian of
the ward, or the personal representative or guardian
is or may be interested adversely to the estate or
ward, or is enforcing the personal representative’s or
guardian’s own debt or claim against the estate or
ward, or the necessity arises otherwise, the court may
appoint an administrator ad litem or a guardian ad
litem, as the case may be, without bond or notice for
that particular proceeding. At any point in a
proceeding, a court may appoint a guardian ad litem
to represent the interests of an incapacitated person,
an unborn or unascertained person, a minor or any
other person otherwise under a legal disability, or a
person whose identity or address is unknown, if the
court determines that representation of the interest
otherwise would be inadequate. If not precluded by
conflict of interest, a guardian ad litem may be
appointed to represent several persons or interests.
The administrator ad litem or guardian ad litem shall
file an oath to discharge all duties faithfully and upon
the filing shall be qualified to act. No process need be
served upon the administrator ad litem or guardian ad
litem, but such person shall appear and defend as
directed by the court.
