Liked a property and getting ready to pay the booking amount? Before you do, there’s one document you cannot afford to skip: the builder-buyer agreement. It’s more than paperwork — it’s the legal safety net that protects your money from the moment you book until the day you get possession.
Most buyers sign it without reading past the first page. That’s where costly mistakes happen — hidden charges, vague possession dates, and one-sided cancellation terms that only surface later. Here’s exactly what to check before you pay a single rupee.
What is a Builder-Buyer Agreement?
A builder-buyer agreement is a legal document signed between a property developer and a homebuyer that defines the exact terms of the sale — price, payment milestones, possession timeline, construction specifications, and the penalties that apply if either party breaks the agreement. For RERA-registered projects, this agreement must also comply with RERA norms, which protect buyers on issues like carpet-area pricing, refund timelines, and compensation for delayed possession.
To protect yourself as a buyer, go through every detail in the agreement and verify it before making any payment. Here are the 15 key things to check.
15 Key Details to Check in a Builder-Buyer Agreement
1. Verify the Builder/Seller’s Ownership and Legal Title
Before paying even a small booking amount, ensure that the builder or seller legally owns the property. If the property does not have a clear title, you risk losing money even before the loan process starts.
- Title documents such as past builder-buyer deeds, gift deeds, or partition deeds
- Latest Encumbrance Certificate (EC) showing clear ownership
- Proof that the seller has the right to sell and the land is not disputed
- For builder floors or apartments, check land ownership documents and development rights
2. RERA Registration Details
Under the Real Estate (Regulation and Development) Act, 2016 (RERA), all real estate projects that meet certain criteria must be registered.
- RERA registration number
- Link to the project on the official RERA website
- Whether the builder-buyer agreement mentions compliance with RERA norms
Why does this matter?
A RERA-registered project means the builder must follow strict guidelines related to timelines, refunds, carpet area, and financial transparency.
3. Check the Exact Carpet Area Being Sold
One of the most important things Indian home buyers often miss is the difference between carpet area, built-up area, and super built-up area. Make sure the agreement does not mislead you with inflated super-built-up area details that do not match real usage space.
RERA mandates that the price must be based on carpet area, so ensure the builder-buyer agreement clearly states:
- Exact carpet area in sq.ft.
- Cost per sq.ft.
- Total price based on carpet area
4. Total Price and Payment Schedule
The builder-buyer agreement must mention the final, all-inclusive price you will be paying. Many buyers later get surprised with added charges. A clear payment plan protects you from sudden, unjustified demands later.
Ensure the agreement includes:
- Base flat cost
- GST (if applicable)
- Floor rise charges
- Preferential location charges (PLC)
- Clubhouse charges
- Electricity/water meter charges
- Parking charges
- Registration and stamp duty costs
- Maintenance deposit or corpus fund
Also verify the payment schedule, including:
- Milestone-based payments
- Due date
- Late payment charges
5. Construction Timeline and Possession Date
Possession delays are one of the biggest concerns among Indian home buyers, especially in under-construction projects. Under RERA, builders are required to pay buyers compensation for delayed possession; make sure this clause is clearly stated.
Your builder-buyer agreement should have:
- Exact date of possession
- Grace period (if allowed)
- Consequences if the builder delays the project
- Penalty compensation the builder must pay for delays
6. Cancellation and Refund Policy
Always check the cancellation clause before paying the booking amount. Many builders put strict terms where buyers lose a big portion of the money if they cancel.
A fair cancellation clause should mention:
- Conditions under which the buyer can cancel
- Refund timeline (usually 45–90 days)
- Any deduction for administrative charges
- Refund method (bank transfer, cheque, etc.)
Also check if the builder can cancel the allotment, this should only be possible under specific legally justified circumstances.
7. Specifications of Construction Material
Many home buyers assume that the builder will use high-quality materials as shown in brochures or sample flats. The builder-buyer agreement must ensure this.
Check for:
- Type of flooring (tiles, marble, wooden flooring)
- Brand and type of bathroom fittings
- Doors and window material
- Electrical wiring brand
- Kitchen platform material
- Waterproofing details
Everything promised in marketing material should be mentioned in writing in the builder-buyer agreement.
8. Layout Plans, Floor Plans, and Project Approvals
Builders often change layout plans after collecting money from buyers. To avoid this:
Confirm in the agreement:
- Final floor plan
- Unit layout (including balcony, utility, and terrace details)
- Car parking location (open, covered, stilt, basement)
- Project approval from local authorities (municipal corporation, town planning dept.)
Also ensure the agreement includes a clause that the builder cannot make major changes without buyer consent.
9. Amenities Promised by the Builder
If the builder has promised amenities like:
- Clubhouse
- Gym
- Swimming pool
- Garden
- CCTV cameras
- Children’s play area
- Power backup
Make sure all these are clearly written in the builder-buyer agreement. Otherwise, the builder may later charge extra or reduce the quality of the amenities.
10. Home Loan Clause and Bank Approval
If you are planning to take a home loan, the builder-buyer agreement should include:
- Details of banks that have approved the project
- Builder obligations during loan processing
- Refund clause if the loan application is rejected
Avoid paying booking amounts until your loan eligibility for the property is clear.
11. Penalty Clauses for Both Parties
A legally balanced builder-buyer agreement should have penalty clauses for both:
- The builder (for construction delay, changes in plan, failure to deliver quality, etc.)
- The buyer (for delayed payments)
Ensure these clauses are fair and not one-sided in favour of the builder.
12. Maintenance Charges and Handover Conditions
Before paying your booking amount, understand how much you will pay after moving in. Builders often delay completing common areas; make sure there are deadlines mentioned.
The agreement must specify:
- Estimated monthly maintenance charges
- Corpus fund
- Handing over of society management to RWAs
- Timeline for completion of common amenities
13. Dispute Resolution Method
The agreement must clearly state:
- How disputes will be resolved
- Jurisdiction (court location)
- Whether disputes will go through RERA or consumer court
14. Check for Hidden Clauses or Ambiguous Wording
Many agreements include vague clauses like “builder may revise plan if required” or “additional charges may apply.” Such clauses can be misused to demand extra money later.
Ask for clarification on any unclear language, such as:
- “Super built-up area subject to change”
- “Possession date subject to approvals”
- “Price escalation charges”
15. Force Majeure Clause
A Force Majeure clause protects both the builder and the home-buyer in situations where delays or disruptions occur due to circumstances beyond anyone’s control. These situations may include natural disasters (floods, earthquakes, cyclones), war, government restrictions, pandemics, or any unforeseen event that makes construction temporarily impossible.
- The clause should clearly define what events qualify as Force Majeure.
- It should mention how much delay is permissible under such events.
- The builder should not misuse the clause to justify delays caused by poor planning or financial mismanagement.
- The agreement must state that once the Force Majeure event ends, the builder must resume construction immediately.
- Buyers should still be entitled to compensation if the delay is not directly linked to a genuine Force Majeure situation.
A well-defined Force Majeure clause ensures transparency and prevents builders from using it as a loophole to escape responsibility for avoidable construction delays.
Builder-Buyer Agreement for Villas and Independent Floors
If you’re buying a villa, plot-based home, or independent floor rather than an apartment, the same 15 points apply — but a few areas need extra scrutiny:
- Land title is verified separately from construction — check the individual plot/khasra number and confirm it matches the EC, not just the project-level title
- “Carpet area” is less standardized for villas — confirm whether pricing is based on plot area, super built-up area, or a combination, and get this in writing
- Core-and-shell vs. fully-finished handover — some villa agreements deliver only the structure, with interiors, flooring, and fittings as a separate cost and timeline
- Utility connections (electricity, water, sewage) are sometimes the buyer’s responsibility post-handover in independent-floor projects — confirm who bears this cost
- Common area maintenance still applies — villa communities typically hand over to an RWA just like apartment societies, so check the same handover and corpus-fund clauses from Point 12
- Setback and boundary wall compliance — confirm the agreement references approved building plans, since unauthorized construction is a common issue in villa/plot developments
Final Thoughts:
Buying a home in India involves several legal and financial steps, and the builder-buyer agreement forms the foundation of your rights as a buyer. Before paying the booking amount, make sure you read the agreement thoroughly, ask questions about any unclear points, and seek legal advice if required. It’s also important to compare the agreement with the builder’s brochure and ensure that every promise made verbally is clearly mentioned in writing. Only proceed with the booking payment once you are fully satisfied with all the terms and conditions.

Frequently Asked Questions
What is the format of a builder-buyer agreement?
A standard builder-buyer agreement includes: buyer and seller details, property description and carpet area, total price and payment schedule, possession date, specifications of construction, amenities list, cancellation and refund terms, penalty clauses, and a dispute resolution clause. Most developers provide a RERA-compliant template, but buyers should still verify each section against the checklist above before signing.
What are the key clauses to check in a builder-buyer agreement?
The clauses that matter most are: RERA registration and carpet area, total price with full payment schedule, possession date with delay-penalty terms, cancellation and refund policy, penalty clauses for both buyer and builder, and the dispute resolution clause. These determine your financial exposure and legal recourse if something goes wrong.
What charges are included in a builder-buyer agreement?
A complete builder-buyer agreement should itemize: base flat cost, GST, floor rise charges, preferential location charges (PLC), clubhouse and amenity charges, electricity/water meter charges, parking charges, registration and stamp duty, and the maintenance deposit or corpus fund. If any of these are missing or vague, ask for clarification before paying.
Is builder-buyer agreement registration mandatory?
Yes. Under RERA and the Registration Act, 1908, a builder-buyer agreement (and the subsequent sale deed) must be registered with the local sub-registrar to be legally enforceable. An unregistered agreement offers significantly weaker legal protection if a dispute arises.
Can I get a copy of the builder-buyer agreement to review with my lawyer before booking?
Yes — and you should insist on it. A reputable builder will share the draft agreement before you pay the booking amount so you, or your lawyer, can review it in full. If a builder is reluctant to share the draft in advance, treat that as a red flag.
