The Core Difference
An Agreement to Sell is a contract to transfer property in the future — it creates a legal obligation but does not transfer ownership. A Sale Deed is the document that actually transfers ownership on a specified date.
Think of it this way: the Agreement to Sell is the promise to sell; the Sale Deed is the sale.
Agreement to Sell: When and Why
You sign an Agreement to Sell when:
What the Agreement should contain:
Key requirement: the Agreement to Sell should be registered at the Sub-Registrar's Office. An unregistered agreement has limited legal enforceability.
Sale Deed: The Ownership Transfer Document
The Sale Deed is executed and registered at the Sub-Registrar's Office on the final transaction day. Registration creates a public record that ownership has transferred from seller to buyer.
What happens on registration day:
After the Sale Deed is registered, you are the legal owner. Apply for patta mutation within 30 days.
What Can Go Wrong Without Proper Documents
Without a registered Agreement to Sell: seller can sell to another buyer and you have limited recourse (only personal lawsuit, not an automatic right to the property). Without a properly executed Sale Deed: ownership doesn't transfer regardless of payment.
Both documents need to be prepared and reviewed by a qualified property advocate before signing.
