Which of the following can qualify as a guardian ad litem?

A guardian ad litem is specifically a person who is appointed by the court to represent the best interests of a child or an incapacitated individual in legal proceedings. This role is crucial in situations where the wards cannot advocate for themselves due to their age or mental state. The guardian ad litem is responsible for assessing the situation, gathering information, and making recommendations to the court regarding what is in the best interests of the child or incapacitated person.

While managing estate finances or aspects of a decedent's estate might involve other roles within the legal framework, such as executors or financial fiduciaries, these roles do not encompass the responsibilities of a guardian ad litem. Similarly, relatives or friends of the family may be involved in various legal proceedings but do not have the specific authority or responsibility that a guardian ad litem holds, which is explicitly defined as representing the interests of those unable to represent themselves in court.
