My Uncle is running a rented Showroom whose lease is not registered, he pays Rent in Cheque for Rs 130000 every month. The Building was in a very poor state when he took over and the market developed after he started his venture. My uncle soent a lot of money on the building and waited for the market to mature. The first unregistered lease was for 2 years and upon its expiry the owner got a new lease signed in April 2010 with the agreed increament but this lease was also not registered. Now since the owner is getting greedy he has sent an email stating eviction. My uncle has put alot of capital and time to develop his business , what are his options as he still pays rent on time and willingly wants to continue paying the rent and do his business. thnks
