My tenant made changes to the rental agreement after we signed it, but before scanning it with the registrar. He didn’t get our signatures on the changes. How can I cancel this agreement? The tenant is currently living in the property.

In India, unilateral alterations to a signed agreement by one party are generally not valid. As the tenant made unauthorized changes without your consent, you can legally argue the agreement is invalid and pursue cancellation. You should consult a lawyer to understand your options and proceed accordingly.
