Section 9

A hirer who is liable to make payments in respect of 2 or more regulated agreements to the same owner shall, notwithstanding any agreement to the contrary, be entitled, on making any payment in respect of the agreements which is not sufficient to discharge the total amount then due under all the agreements, to require the owner to appropriate the sum so paid by him in or towards the satisfaction of the sum due under any one of the agreements, or in or towards the satisfaction of the sums due under any 2 or more of the agreements in such proportions as he thinks fit.

If the hirer fails to make any such appropriation as mentioned in subsection (1), the payment shall by virtue of this section be appropriated towards the satisfaction of the sums due under the respective regulated agreements in the order in which the agreements were entered into.
