My grandma is currently in the process of selling her real estate business but there is no signed papers or any money transfer. she just signed a 2 year lease for the building for her business. the guy who wants to buy her business contacted her landlord and together they wrote up, signed, and notarized a lease to start as of November 1st 2008. They never talked about how my grandma was to get out of her lease. Is what the landlord did legal? he currently has two leases under two business names to the same property, who is then responsible for the rent? PLEASE HELP
