Section 11 Applications may be made by guardians on behalf of minors and persons under disability.

In every case in which it is competent for an heir in possession of an entailed estate, being of full age and not subject to any legal incapacity, to make an application to the Court under the Entail Acts, it shall hereafter be competent for an heir in possession, though a minor, with consent of his curators, or for the tutors of an heir in possession, if he is a pupil, or for his curator or other administrator if he is otherwise incapacitated, to make such application, not being an application for authority to disentail the entailed estate or any part thereof, and to execute and carry into effect any authority which may be given by the Court.
