Where any sum has, whether before or after the commencement

Where any sum has, whether before or after the commencement of this Act, been paid which sum by reason of the provisions of the Act should not have been paid, such sum shall, at any time within a period of six months after the date of payment, be recoverable by the tenant from the landlord who received the payment or his legal representative, and may, without prejudice to any other method of recovery, be deducted, within such six months, by such tenant from any rent payable by him to such landlord. Explanation.—In this section the expression "legal representative" has the same meaning as is assigned to it in the code of Civil Procedure, 1908, and includes, in the case of joint family property, the joint family of which the deceased person was a member.
