Location is the main factor when it comes to estimating the value of buffer paper. The duration of the agreement also plays a role. Stamp duty on short- and long-term leases varies from state to state. Plus, your annual rent is also a factor, especially for commercial leases. Leases of one year or more must be registered. For contracts of less than one year, only stamp duty applies, while registration is not mandatory. Delhi has abandoned traditional buffer paper systems and completely switched to the electronic stamping system of the Stock Holding Corporation of India (SHCIL). If a person needs stamp paper, they can contact electronic stamping suppliers and buy it from them. You must provide your name and subject matter in the application form. Traditional stamp papers are no longer used in Delhi. .
