An attorney ad litem (“AAL”) is an independent attorney the court may appoint to advocate on behalf of the person with the disability. The court shall appoint an attorney ad litem to represent the respondent on the respondent’s request, upon the recommendation of the guardian ad litem or if it appears to the court to be necessary to protect the rights or interests of the respondent. The attorney ad litem shall be an advocate for the respondent in resisting the requested relief.
