After 100 years you (your grand children) will get a notice stating the lease is over. You would then have two options.What is the difference between a regular registration and a 99 year lease registration? If the buyer wants to sell the house how does it work? The buyer will be the owner for 99 years after which the landowner can assert ownership of the land again. In short, a 99 year lease India is a lease where a property is leased out for 99 years only. You flat will be leasehold only as you (or other flat owners) don't own the actual land. By default (unless otherwise mentioned) it is 99 years.
