Sir, in this case, there is no need to worry as if the lease deed is more then one year then it has to be registered and as per the judgment of the supreme court if the lease deed of more than one year is not registered then it will be held as monthly lease whereby you can issue 106 notice under transfer of property act asking him to vacate the premises giving 15 days time and if he fails to vacate you can file a suit for eviction in court.
