This discussion clarifies whether a rent agreement can be backdated to a date prior to the e-stamp paper purchase. The consensus is that while the tenancy can commence on an earlier date (e.g., 24th October 2021), the agreement itself must be executed on or after the e-stamp paper's date (25th October 2021). It's crucial to ensure the correct stamp duty and registration charges are paid to avoid legal issues if the agreement needs to be presented as evidence.
