Extension of appointment of guardian beyond child’s eighteenth birthday

(1) The appointment of a guardian shall expire upon the child attaining the age of eighteen years, unless exceptional circumstances exist that would require a court to make an order that appointment be extended.
(2) The exceptional circumstances referred to in subsection (1) are that the child suffers from a mental or physical disability or from an illness that will render him incapable of maintaining himself, or of managing his own affairs and his property without assistance of a guardian after his eighteenth birthday or such other exceptional circumstances with regard to the child as the court may deem proper to warrant the making of an order under this section.
(3) Where an order is made under subsection (1), it shall be made prior to the child’s eighteenth birthday and may be made on an application by—
(a) the child;
(b) the parent or guardian of the child;
(c) a relative of the child; or (d) the Secretary:
Provided that no order shall be made without the consent of the child, if he is capable of giving such consent, and of the guardian whose appointment is required to be extended.
(4) A court making an order under this section may attach such conditions as to the duration of the order and containing directions as to how it shall be carried out, imposing such other conditions that must be complied with and with such incidental, supplemental or consequential provisions as the court thinks fit.
(5) A court shall have power to vary, modify or revoke any order made under this section after the child’s eighteenth birthday, on the application of any of the persons named in subsection (3), or where the child marries after his eighteenth birthday, his spouse.
