After 100 years you (your grand children) will get a notice stating the lease is over. You would then have two options.I am staying in Delhi and have inherited a leased land at Sector 1 in Salt Lake in Kolkatta. The buyer will be the owner for 99 years after which the landowner can assert ownership of the land again. Anyone who purchases a residential or commercial property will own it only for a period of 99 years, after which the ownership is given back to the landowner.
