Until the court has confirmed an appointee under section 5‑202, a minor who is the subject of an appointment by a parent and who has attained 14 years of age, the other parent or a person other than a parent or guardian having care or custody of the minor may prevent or terminate the appointment at any time by filing a written objection in the court in which the appointing instrument is filed and giving notice of the objection to the guardian and any other persons entitled to notice of the acceptance of the appointment. An objection may be withdrawn and if withdrawn is of no effect. The objection does not preclude judicial appointment of the person selected by the parent if all other requirements for appointment, including appointment over the objection of a parent, are met. The court may treat the filing of an objection as a petition for the appointment of an emergency or interim guardian under section 5‑204 and proceed accordingly.   [PL 2017, c. 402, Pt. A, §2 (NEW); PL 2019, c. 417, Pt. B, §14 (AFF).]
