Property Buying Guide: Understand BBA vs ATS in Simple Words
Buying a home is a big decision and involves a lot of paperwork. Two of the most important documents in this process are the Builder-Buyer Agreement (BBA) and the Agreement to Sell (ATS). Many buyers get confused about these documents, their purpose, and what to look for before signing. This blog explains everything in simple words, so anyone can easily these legal terms and stay informed and safe.
What is a Builder-Buyer Agreement (BBA)?
The Builder-Buyer Agreement is a legal paper signed between the builder (the seller) and the buyer. It clearly mentions the details of the property, payment plan, possession date, and responsibilities of both the builder and the buyer. This document is usually signed after the initial booking amount is paid.
Key Things You’ll Find in the BBA:
Advance Payment: The first amount you pay to block the property.
Possession Date: When the builder promises to hand over your home.
Payment Schedule: How and when you will pay the total cost, step by step.
Defect Liability Period: A fixed time after possession during which the builder must fix any construction issues.
What is an Agreement to Sell (ATS)?
The Agreement to Sell is also a legal document but comes before the final Sale Deed. It says that the seller agrees to sell the property, and the buyer agrees to buy it under specific conditions. Once the full payment is done, the final Sale Deed is registered.
Important Details Mentioned in ATS:
Sale Price (Sale Consideration): The total cost of the property.
Stamp Duty: A government tax the buyer pays while registering the property.
Transfer of Title: This confirms the legal shift of property ownership from the builder to the buyer.

Payment Schedule Explained Simply

Construction-Linked Payments: Payments made after certain stages like laying the foundation, building structure, etc.
Final Payment: Paid when the home is almost ready to be handed over.
Things to Check Before Signing BBA or ATS
Always read the document carefully and check these points:
Force Majeure Clause: This says that the builder is not responsible for delays caused by natural events like floods or earthquakes. Still, the time limit for such delays should be clearly mentioned.
Termination Clause: What if the builder doesn't complete the work? This clause explains when and how you can cancel the deal and get your money back.
Possession Conditions: Make sure it clearly says what kind of finishing and facilities you will get (e.g., paint, flooring, electric fittings).
Legal Check: Always get these documents reviewed by a property lawyer. Also, check if the project is RERA registered.
Tips to Protect Yourself as a Buyer
• Always take everything in writing. Verbal promises don’t count.
• Never delay payments as per the schedule.
• Check if the builder has all government approvals.
• Ask for the latest sanctioned plan and verify it with local authorities.
Make sure the agreement mentions the penalty the builder will pay if there’s a delay in giving possession.
