(3) An application for a declaration under this section shall not be made in relation to a child concerned other than—

(b) where the application is made by a person referred to in subsection (2)(b), on notice to each guardian of the child.

(4) The court may direct that notice of any application for a declaration under this section shall be given to such other persons as the court thinks fit and where notice is so given or where notice is given under subsection (3) to any person the court may, either of its own motion or on the application of that person or any party to the proceedings, order that that person shall be added as a party to those proceedings.

(5) Where on an application for a declaration under this section it is proved on the balance of probabilities that a person named in the application is or is not a guardian by virtue of the circumstances set out in section 2(4A) or 6B(3) of the child concerned, the court shall make the declaration accordingly.]
