I have inducted tenant in my flat in Delhi in 2008 on oral lease of 11 months @ Rs.3400/- per month. Tenant paid rent for a year and stopped paying rent henceforth. Now I hv filed eviction petition for rent recovery. Taking advantage of oral lease, he claims rent as Rs.1600/- per month before the court. How can I prove rent was Rs.3,400/- per month as it was on oral lease and hv not issued receipts for an year. Pls. advise? sekhar
