Redemption of rent under section 64

When the dwelling-house of one proprietor, with the buildings and grounds immediately attached thereto, has been included in the separate estate of another proprietor, and the rent to be paid in perpetuity for the land occupied thereby has been fixed by the Deputy Collector and stated in the paper of partition, the first-mentioned proprietor may apply to the Deputy Collector for permission to redeem the rent so fixed, and the Deputy Collector shall give such permission unless he is of opinion that the redemption would endanger the safety of the land-revenue for the payment of which the separate estate in which such dwelling-house, buildings and grounds have been included will be liable.
