I read the case of the tenant and the owner in which the tenents daughter got married to the son of the owner and after few days went back to her parents, my question related to the agrement is"is it possible to include a clause which allows for per month penalty if the tenent does not vacate the house according to the agrement? example: If the tenent fails to vacate the house untill agreed date a penalty of 10% of rent value of previous month will be payable by the tenent .Note that every month there will be increase of 10% on the accumulated value of the rent of previous month). If the rent is 1000, and tenent did not vacate in June suppose, then july rent will be Rs1100/, in august it will be 1210, in september it will be 1331, oct will be 1464, like this it will keep on increasing untill the tenent vacates. Is is allowed to be included in the agrement?
