Buying a property is a major financial commitment, so checking the right documents before making a payment is essential. The documents to check before buying a property include the title documents, RERA details, approved plans, sale agreement, approvals, completion or occupancy documents, tax records and other papers related to the property. These documents help buyers understand who owns the property, whether the project has the required approvals and whether the information provided by the seller matches the official records.

For buyers looking at residential projects in Gurgaon, document verification becomes especially important because different projects can have different development stages, approvals, timelines and ownership structures. A careful document check can help identify discrepancies before they become costly problems.This guide by Vintage Vista explains the important property documents buyers should review before booking a home and what each document tells you.

Why Document Verification Matters

A property may look perfect during a site visit, but the physical appearance of a project does not confirm its legal or regulatory status.

Before buying, buyers should verify:

• Ownership and title of the land
• Project registration
• Approved building and layout plans
• Development permissions
• Encumbrances or claims
• Sale and allotment documents
• Completion or occupancy status
• Property tax and other applicable dues
• Area and unit specifications
• Possession-related documents

For registered projects in Haryana, the Haryana Real Estate Regulatory Authority makes project information available online, including registration details and various project documents.This makes official verification an important part of the property-buying process.

1. RERA Registration Details

For a new or ongoing RERA-registered project, RERA registration details should be one of the first things buyers check.Under Section 3 of the RERA Act, a promoter generally cannot advertise, market, book or sell a real estate project in a planning area without registering it with the Real Estate Regulatory Authority, subject to the exemptions provided by law.

When checking RERA information, look at:

• RERA registration number
• Project name
• Promoter name
• Project location
• Registered project area
• Proposed completion date
• Number and type of units
• Approved plans and specifications
• Quarterly progress information
• Project-related orders or updates

For Gurgaon properties, buyers can verify the project through the Haryana RERA portal rather than relying only on information provided in brochures or sales presentations.

2. Title Deed and Ownership Documents

The title deed is one of the most important property documents to verify.

It helps establish the ownership or legal title associated with the land or property.

For a development project, buyers should understand:

• Who owns the land
• How the promoter acquired development rights
• Whether the title is properly documented
• Whether there is a chain of title
• Whether any other party has rights or interests in the land

Haryana’s RERA rules require project registration information to include an authenticated legal title deed and legally valid documents reflecting the chain of title.

For buyers, this is an important reason not to rely solely on verbal statements about land ownership.

3. Encumbrance Details

An encumbrance can indicate a claim, liability, interest or other legal issue associated with the property or land.

Buyers should check whether the land has:

• Loans or mortgages
• Legal claims
• Liens
• Rights or interests of other parties
• Outstanding dues
• Litigation

Haryana’s RERA framework requires disclosure of encumbrances and related rights, title, interests, dues and litigation concerning project land.

If you are buying an individual resale property, the document requirements and verification process can differ from those for a new developer project. In such cases, professional legal review can be particularly useful.

4. Approved Building and Layout Plans

Don’t assume that the property shown in a brochure is automatically the same as the officially approved development.

Check the relevant:

• Building plan
• Layout plan
• Site plan
• Floor plan
• Tower plan
• Common-area plan
• Amenity plan

Haryana RERA rules provide for disclosure of sanctioned zoning/building plans, layout plans, floor plans and other project specifications.Compare the approved information with what the sales team is showing you.

This can help you understand whether the advertised configuration, tower, amenities and development details align with the approved project information.

5. Land Use and Development Approvals

Depending on the type and location of the project, buyers should also understand the relevant land-use permissions, licences and development approvals.

These may include applicable:

• Land-use permissions
• Development licences
• Building approvals
• Environmental clearances
• Fire-related approvals
• Water and sewerage permissions
• Other statutory permissions

The exact approvals required can vary according to the project and applicable regulations.

Haryana RERA’s published rules specifically refer to licences, land-use permissions, sanctioned building plans and other required approvals and clearances.

6. Agreement for Sale

The Agreement for Sale is a crucial document because it sets out important terms between the promoter and buyer.

Before signing, carefully review:

• Property details
• Unit number
• Carpet area
• Payment schedule
• Possession date
• Default provisions
• Interest provisions
• Cancellation terms
• Maintenance-related provisions
• Specifications
• Common-area information
• Other rights and obligations

Under Section 13 of RERA, a promoter cannot generally accept more than 10% of the cost of an apartment, plot or building as an advance/application fee without first entering into a written agreement for sale and registering it as required by law. The agreement also specifies important details including development, payment terms and possession.Do not sign the agreement without reading the terms carefully.For a significant property purchase, getting the agreement reviewed by a qualified property lawyer can be worthwhile.

7. Allotment Letter

For many new residential projects, the allotment letter forms an important part of the buyer’s documentation.

Check that it correctly mentions:

• Buyer’s name
• Project name
• Unit number
• Tower
• Floor
• Configuration
• Area
• Basic price
• Applicable charges
• Payment schedule
• Other relevant terms

Cross-check these details against the booking form, cost sheet and Agreement for Sale.

Any difference should be clarified before you proceed.

8. Occupancy Certificate

If you are buying a completed or possession-ready property, check whether the applicable Occupancy Certificate (OC) has been issued.

An occupancy certificate is important because it relates to the authorised occupation of the completed development, subject to applicable local requirements.

For completed projects, buyers should ask:

Has the relevant OC been issued?

If the project is being handed over in phases, check the certificate applicable to the specific phase or building.

Haryana RERA’s published rules include part completion/completion and occupation certificates among the project information and documents to be disclosed.

9. Completion Certificate

A Completion Certificate (CC) is another important document associated with project completion.Depending on the project and applicable regulations, the CC can confirm that development has been completed in accordance with the approved requirements.

For buyers purchasing a completed property, ask the developer or seller for the relevant completion documentation and verify its applicability to the specific property or phase.

10. Sale Deed or Conveyance Deed

For a resale property, the registered sale deed is especially important because it forms part of the chain showing transfer of ownership.For a new project, the conveyance deed becomes relevant to the eventual transfer of title in accordance with applicable law and project documentation.

Under RERA, the promoter is required to execute a registered conveyance deed in favour of the allottee and hand over the relevant title documents according to the applicable provisions and local laws.

Before purchasing a resale property, check the previous registered sale deeds and relevant ownership documents to understand the title chain.

11. Property Tax and Utility Dues

A buyer should also check whether there are any outstanding dues associated with the property.

Depending on the property, these may include:

• Property tax
• Electricity bills
• Water charges
• Maintenance dues
• Society charges
• Other applicable municipal or service dues

For a resale property, ask the seller for relevant receipts or statements showing that applicable dues have been cleared.

This can help prevent unexpected liabilities after the transaction.

12. Floor Plan and Property Specifications

Before signing anything, compare the actual property details with the documents.

Check:

• Unit number
• Floor
• Carpet area
• Balcony area
• Terrace area, where applicable
• Parking allocation
• Number of bedrooms
• Utility areas
• Other included spaces

RERA project disclosures can include the number and carpet area of apartments as well as exclusive balcony, verandah and open terrace areas.

Don’t rely only on a sales brochure when confirming these details.

13. Bank Approval and Loan Documents

If you are taking a home loan, your lender will conduct its own assessment of the property and documentation.

However, bank approval should not replace your own due diligence.

Check:

• Loan sanction terms
• Property-related legal assessment
• Mortgage requirements
• Disbursement conditions
• Required documents
• Applicable processing charges

A bank’s willingness to finance a property does not mean buyers should skip independent document verification.

14. Seller’s Identity and Authority

For a resale property, verify the identity and authority of the person selling the property.

Check:

• Seller’s identification
• Ownership documents
• Authority to sell
• Power of attorney, if applicable
• Co-owner consent, where applicable
• Previous sale deed
• Relevant inheritance documents, if applicable

If someone is signing on behalf of the owner, understand the legal basis for that authority before proceeding.

Should You Get Property Documents Legally Verified?

Yes, particularly when the property represents a significant financial investment.A property lawyer can examine documents such as the title chain, sale deed, development agreements, encumbrances and other legal records and identify issues that a buyer may overlook.

For new projects, buyers should also independently compare developer-provided information with official RERA records. Documents Before Buying Property should always be checked against reliable and official sources wherever possible. Vintage Vista can help buyers shortlist properties, compare projects, understand available information and coordinate the property-buying process. However, Documents Before Buying Property can involve legal and regulatory details, so buyers should consult a qualified property lawyer for legal title verification or legal opinions. Reviewing Documents Before Buying Property carefully can help buyers make a more informed decision before committing to a major investment.
