Sup. Ct. R. D.C. 117
COMMENT
Civil Rule 17(c) provides that a representative, a next friend, or a guardian ad litem appointed by the court, may sue or defend on behalf of a minor or incompetent person. This rule supplements Civil Rule 17(c) and recognizes the inherent power of the court, as an incident of its jurisdiction, to appoint guardians ad litem to represent the interests of all those whose representation would otherwise be inadequate, including the interests of unascertained and unborn beneficiaries and unknown persons. See Hatch v. Riggs National Bank , 361 F. 2d 559, 565-566 (D.C. Cir. 1966) .
The rules governing trusts provide that a guardian ad litem is not required for the appointment of a successor, substitute, or additional trustee.
A guardian ad litem for the subject in an intervention proceeding or a ward is governed by Rule 308.
