Common questions
Frequently Asked
4
When may a lawyer seek appointment of a guardian ad litem for a client?+
A lawyer may seek the appointment when the lawyer reasonably believes the client has diminished capacity, faces substantial risk of harm, and cannot adequately protect personal interests. The appointment serves as one form of protective action under the applicable professional conduct rules.
Does a guardian ad litem replace a trustee or other fiduciary?+
No. A guardian ad litem is appointed only for the limited purpose of a specific suit and does not assume ongoing fiduciary duties such as those of a trustee or conservator. The role ends when the litigation concludes.
May a minor or incompetent person sue without a guardian ad litem?+
A minor or incompetent person without a duly appointed representative may sue by next friend or guardian ad litem. The court must appoint a guardian ad litem or issue another protective order when the person is unrepresented in the action.
How does a guardian ad litem protect a minor beneficiary during trust termination?+
The guardian ad litem represents the minor's interests when beneficiaries seek to terminate an irrevocable trust and agree on a non-pro rata distribution. Court approval of the agreement after the guardian's participation binds the trustee to follow the agreed distribution rather than the original trust terms.
