Every ryot who has cultivated or held land for a period of twelve years has a right of occupancy in the land so cultivated or held by him, whether it be held under pottah or not, so long as he pays the rent payable on account of the same; but this rule does not apply to khomar, neejjote, or seer land belonging to the proprietor of the estate or tenure and let by him on lease for a term or year by year, nor (as respects the actual cultivator) to lands sublet for a term or year by year by a ryot having a right of occupancy. The holding of the father, or other person from whom a ryot inherits, shall be deemed to be the holding of the ryot within the meaning of this Section.
