12. Any instalment of revenue or rent which is not paid on or before the day when the same becomes due, whether under a written agreement or according to law or local usage, shall be deemed to be, for the purposes of this Act, an arrear of revenue or rent, as the case may be. Provided that, unless the proprietor and under-proprietor shall have otherwise agreed in writing, the rent payable to the former by the latter shall be held to become due one month before the date fixed for the payment of the revenue on account of the village in which the land in respect of which such rent is payable is situate, and to be payable in the same number of instalments as the said revenue; and the amount of each instalment of such rent shall bear the same proportion to the whole of such rent payable for the year, as the amount of each instalment of such revenue bears to the whole of such revenue payable for the year.
