The authority that finalized tenders and under whom you are operating is the competent authority. Every fact is needed in the form of data. Collect data of last year's actual charges and this year charges month-wise, the actual lockdown period, and pray for reduction of the contract amount proportionately based on per day contract rate. This maybe your proposal and they may discuss and propose some other and both have to reach for a common remedy. What is the total contract per annum and what works out for one day in a year, and add 30 days for the actual locking period? The government itself is coming with proposals that landlords should postpone the rent and should not bring pressures. Against this background, you can certainly get a relief. As there is lock-in period and also vacation, most of the advocates have free time and you can provide them with much needed data and can get a draft for an amount not exceeding Rs.1,000/- from a best advocate in your town.
