What is the duty of a guardian of minor’s property under Section 27 of the Guardians and Wards Act, 1890?

Section 27 of the Guardians and Wards Act, 1890 requires a guardian of a ward's property to deal with it as carefully as a man of ordinary prudence would deal with his own, and, subject to the Act, he may "do all acts which are reasonable and proper for the realisation, protection or benefit of the property". A guardian appointed or declared by the Court needs the Court's previous permission under Section 29 to mortgage, sell or (beyond the limits there) lease the ward's immovable property, and he cannot treat the ward's rents as his own.
