Buying a new flat, villa or plot from a builder involves several documents, but the Builder-Buyer Agreement is one of the most important.
It sets out the terms under which the builder or promoter agrees to sell the property and the buyer agrees to purchase it. The agreement can cover the property's specifications, price, payment schedule, possession timeline, construction obligations, cancellation terms, maintenance and other rights and responsibilities.
Under the Real Estate (Regulation and Development) Act, 2016 (RERA), a promoter cannot accept more than 10% of the cost of an apartment, plot or building as an advance or application fee without first entering into a written agreement for sale and registering that agreement.
That makes the agreement much more than a formality. Before signing it, a buyer should carefully compare its terms with the builder's brochure, allotment letter, payment plan, RERA disclosures and promises made during the sale process.

What Is a Builder
Buyer Agreement?
A Builder-Buyer Agreement, commonly referred to as an Agreement for Sale, is a legal document between the promoter and the buyer that records the terms of the property transaction.
It generally contains details such as:
- Name and details of the builder/promoter
- Name and details of the buyer
- Project and unit details
- Carpet area
- Total price
- Payment schedule
- Possession date
- Construction specifications
- Amenities and facilities
- Maintenance arrangements
- Delay-related provisions
- Cancellation and termination conditions
- Default by buyer or promoter
- Defect-related obligations
- Registration and conveyance provisions
In Uttar Pradesh, UP RERA has notified a Model Agreement for Sale, and the Authority specifically advises buyers to check whether the agreement follows the notified model.

Builder
Buyer Agreement vs Allotment Letter
These two documents are often confused.
An allotment letter generally records the allotment of a particular unit to the buyer and may contain basic commercial terms.
The Agreement for Sale is more comprehensive and sets out the contractual rights and obligations of the promoter and buyer.
UP RERA's project records, for example, separately list the proforma of the application form, allotment letter, agreement for sale and conveyance deed.
Therefore, don't assume that signing an allotment letter means you have reviewed the complete terms of the eventual sale agreement.
Why Is the Builder
Buyer Agreement Important?
A buyer may hear several promises during the sales process:
"Possession will be given on time."
"This amenity will be included."
"The price includes everything."
"There will be no additional charges."
But verbal assurances can be difficult to rely on if they are not properly reflected in the contractual documents.
The agreement provides a written record of the transaction.
It can help you understand:
- What exactly you are buying
- What you are paying for
- When payments are due
- When possession is expected
- What happens if possession is delayed
- What happens if the buyer defaults
- What happens if the builder defaults
- Which facilities are promised
- How cancellation works
- Which charges are payable separately
This is why reading the agreement before signing or making a substantial payment is important.

Important Clauses to Check in a Builder
Buyer Agreement
1. Project and Property Details
Start with the basics. The agreement should correctly identify:
- Project name
- Phase/tower
- Unit number
- Floor
- Apartment type
- Carpet area
- Parking, where applicable
- Project address
- Relevant plans or schedules
Compare these details with the allotment letter and RERA project information.
A mismatch in the unit number, area, floor or project phase should be clarified before signing.
2. Carpet Area
Pay close attention to the carpet area. Under RERA, carpet area is an important basis for the sale of apartments. UP RERA also specifically advises buyers that apartment area should be stated in terms of carpet area.
Do not compare properties only on the basis of "super area," "saleable area" or similar marketing terminology.
Ask the builder for a clear breakup of:
- Carpet area
- Balcony/terrace area, where applicable
- Other areas mentioned in the agreement
The price calculation should be clear enough for you to understand what you are actually paying for.
3. Total Price and Cost Breakup
One of the most important sections is the total consideration.
Check whether the agreement clearly identifies:
- Basic sale price
- Applicable taxes
- Parking charges, if any
- Preferential location charges, if applicable
- Club or amenity charges
- Maintenance-related charges
- Infrastructure charges
- Other one-time charges
- Recurring charges
- Registration and stamp-duty responsibilities
Do not rely only on the salesperson's cost sheet.
Compare the cost sheet with the agreement and ask for clarification about every unexplained amount.
4. Payment Schedule
The agreement should clearly mention when instalments are payable.
Check:
- Booking amount
- Subsequent instalments
- Construction-linked payments, if applicable
- Demand notice procedure
- Due dates
- Late-payment consequences
- Applicable interest
Also check whether the payment schedule corresponds with the project's actual construction milestones where it is described as construction-linked.
5. Possession Date
The possession clause deserves special attention.
Check:
- Promised possession date
- Conditions attached to possession
- Whether the date is linked to a specific period
- Procedure for offering possession
- Consequences of delay
- Buyer's rights in case of prolonged delay
Do not rely solely on a salesperson saying that possession will be provided "soon."
The contractual date and applicable RERA terms should be checked carefully.
6. Delay in Possession
Find out exactly what happens if the builder does not deliver the property within the applicable contractual timeline.
The agreement should be read alongside the buyer's rights under RERA and applicable rules.
A buyer should understand:
- Whether compensation/interest is payable
- How it is calculated
- From which date it becomes applicable
- Whether the buyer can seek withdrawal/refund in circumstances permitted by law
- What happens to amounts already paid
Don't skip this section simply because you expect the project to be delivered on time.
7. Specifications and Construction Quality
The agreement should clearly refer to the promised specifications.
Check details such as:
- Flooring
- Doors and windows
- Electrical fittings
- Sanitary fittings
- Kitchen specifications
- Paint
- Fixtures
- Air-conditioning provisions
- Power backup
- Other promised installations
If a specification is important to you, don't depend solely on a brochure or sample flat.
Check whether the relevant specification is included in the agreement or its schedules.
8. Amenities and Common Areas
A project's amenities can be a major part of its sales pitch. The agreement should make it clear what facilities are associated with the project and, where relevant, the phase or building.
Check references to:
- Clubhouse
- Swimming pool
- Gym
- Children's play area
- Sports facilities
- Gardens
- Parking
- Security
- Roads
- Community facilities
This is particularly important in large projects developed in multiple phases.
UP RERA's model agreement framework recognises that facilities and amenities can involve progressive or mixed development across phases, so buyers should understand how and when promised facilities are to be delivered.
9. Changes in Layout or Specifications
Read the clause dealing with changes to:
- Building plans
- Unit layout
- Common areas
- Amenities
- Specifications
- Project development
Understand what changes the promoter can make and what approvals or consent may be required.
A broad clause giving unrestricted power to change important aspects of the project deserves careful review.
10. Cancellation and Refund Clause
Before signing, understand what happens if:
- The buyer wants to cancel
- The builder defaults
- The project is delayed
- The buyer misses payments
- The transaction cannot proceed for a specified reason
Check:
- Cancellation charges
- Refund timeline
- Deductions
- Interest provisions
- Notice requirements
Never assume that the booking amount is automatically refundable or automatically forfeited. The agreement and applicable law matter.
11. Default by Buyer
The agreement will usually specify what happens if the buyer fails to make payments on time.
Check:
- Late-payment interest
- Notice period
- Cure period, if applicable
- Cancellation rights
- Forfeiture provisions
- Refund procedure
Make sure you understand these provisions before signing.
12. Default by Builder
The agreement should also address the promoter's obligations.
Look for provisions dealing with:
- Delay
- Failure to complete the project
- Failure to provide promised facilities
- Failure to execute the conveyance
- Failure to meet applicable contractual obligations
A contract should be read as a whole rather than focusing only on buyer-default clauses.
13. Defect Liability
For a new property, check the provisions relating to construction or quality defects.
RERA contains provisions concerning defects in structural quality, workmanship, provision of services and other obligations, subject to the statutory conditions.
UP RERA also identifies defect liability period as an important component of the model agreement framework.
Understand:
- What constitutes a defect
- How defects should be reported
- Who bears the cost of rectification
- The applicable period
- The procedure for raising complaints
14. Possession and Occupancy Documents
Before taking possession, understand which documents and approvals are relevant to the property.
Depending on the project and applicable law, these can include:
- Completion Certificate
- Occupancy Certificate
- Possession letter
- Utility-related approvals
- Other applicable authority clearances
UP RERA project records include documents such as commencement certificates, occupancy/completion-related documents, sanctioned plans, utility plans and agreement-for-sale documents.
15. Maintenance and Association Charges
Check who will maintain the project and when the responsibility changes.
The agreement may address:
- Maintenance charges
- Common-area maintenance
- Sinking fund
- Club charges
- Maintenance agency
- Handover to association
- Electricity/water-related charges
- Advance maintenance
Ask for a clear explanation of one-time versus recurring charges.
16. Parking Rights
Parking can become a source of confusion in apartment purchases.
Check what the agreement actually says about:
- Number of parking spaces
- Type of parking
- Location
- Whether it is allotted, licensed or otherwise described
- Charges, if any
Do not rely only on a verbal promise that "parking is included."
17. Registration and Conveyance
The agreement should explain the process leading to the eventual transfer/conveyance of the property.
Check:
- Who will execute the conveyance deed
- When it will be executed
- Registration responsibilities
- Stamp duty and registration charges
- Handover of documents
The Agreement for Sale is not the same thing as the final registered conveyance/sale deed.
18. Encumbrances and Title
Before signing, check the project's land title and encumbrance-related information.
The UP RERA project portal, for example, can contain promoter-uploaded information including land documents and details of encumbrances for registered projects.
A buyer should independently review the relevant title documents and not rely solely on the agreement's declarations.
For a high-value purchase, independent legal due diligence is advisable.
19. Force Majeure Clause
The agreement may contain a force majeure clause dealing with events beyond the parties' control.
Read:
- What events are covered
- How the clause affects the possession timeline
- Whether the promoter can extend deadlines
- What notice must be given
- Whether the extension has any limits
A broad force majeure clause should be understood carefully rather than accepted without reading.
20. Dispute Resolution and Jurisdiction
Finally, check how disputes are to be handled.
Look for provisions concerning:
- RERA remedies
- Arbitration, if included
- Courts/tribunals
- Jurisdiction
- Notice procedure
- Applicable law
A contractual clause should not be read as removing statutory rights available to a homebuyer under applicable law.

Buyer Agreement Checklist
Before signing, compare the agreement against this checklist:
Documents to Compare Before Signing
Don't read the Builder-Buyer Agreement in isolation. Compare it with:
- RERA registration details
- Application form
- Allotment letter
- Payment plan
- Price sheet
- Project brochure
- Floor plan
- Specifications sheet
- Approved/sanctioned plans, where relevant
- Land/title documents
- Encumbrance information
- Promoter's disclosures
- Any written commitment made during booking
UP RERA project records demonstrate that project documentation can include the agreement-for-sale proforma, allotment letter, conveyance deed, sanctioned plans, commencement certificate and encumbrance details.
If an important promise appears in a brochure but disappears from the agreement, ask the builder to clarify it before signing.

Buyer Agreement in UP and Noida
For buyers purchasing property in Noida, Greater Noida or elsewhere in Uttar Pradesh, UP RERA is particularly relevant for applicable registered real estate projects.
UP RERA has notified a Model Agreement for Sale, and its buyer guidance highlights three practical points: buyers should check whether the agreement follows the notified model, promoters should not collect more than 10% of the unit cost before executing the Agreement for Sale, and apartment area should be stated in carpet-area terms.
The UP RERA portal also makes project-related documents available for registered projects, which can help buyers compare the agreement with the project's disclosed information.
For a Noida or Greater Noida property, therefore, it is useful to check the UP RERA project details, promoter information, sanctioned plans, agreement-for-sale proforma and other available disclosures before signing.
Can a Buyer Make Changes to a Builder
Buyer Agreement?
A buyer can request clarification or changes, but whether a particular provision can be changed depends on the promoter, applicable law and the nature of the clause.
Do not assume that a standard agreement cannot be questioned.
If you identify an important issue, raise it before signing and registering the agreement.
In a UP RERA example, the agreement itself states that amendments may be made through written consent of the parties and that agreed additions to the model format can become binding contractual terms.
For significant changes, have the revised language reviewed before accepting it.
Final Takeaway
A Builder-Buyer Agreement is one of the most important documents in a new-property purchase because it records the commercial and contractual terms between the buyer and promoter.
Before signing, don't focus only on the property price. Check the carpet area, payment schedule, possession date, delay provisions, specifications, amenities, cancellation terms, maintenance charges, parking, defect liability, conveyance and dispute provisions.
Also compare the agreement with the project's RERA disclosures, allotment letter, price sheet and other documents.
For a significant property purchase, getting the agreement reviewed by an independent property lawyer before signing can help you understand clauses that may have long-term financial or legal consequences.
