After 100 years you (your grand children) will get a notice stating the lease is over. You would then have two options.The buyer will be the owner for 99 years after which the landowner can assert ownership of the land again.

A lease exceeding 99 years is void under the law as a suppression of California public policy encouraging the free exchange and development of land. The Department of the Interior today announced its endorsement of legislation that would permit the leasing of Indian lands on the Navajo Reservation. Several authorities offer land to develop apartment projects, only on leasehold basis. Indianapolis colloquially known as Indy, is the capital and most populous city of the U.S. state of Indiana and the seat of Marion County. Warning: this story will likely make you itch BAD.
