Section 21

No representation shall be granted to a person of unsound mind, but where any such person, if of sound mind, would be entitled to representation, letters of administration with or without the will annexed may, subject to section 4, be granted to the person to whom the care of his estate has been lawfully committed, or to such person as to the Court seems fit, for the use and benefit of the person of unsound mind, until he becomes of sound mind and obtains a grant to himself.
