Property Documents You Must Check Before Buying a Home

Before finalising a home purchase, it is crucial to carefully verify all property documents to avoid disputes, financial loss or future legal complications. Beyond location, price and amenities, the legal validity of the property is equally important. Overlooking key documents can result in disputes, financial loss or lengthy court battles. A careful review of property documents ensures clear ownership, regulatory compliance and peace of mind. The following are the essential documents every buyer must verify before finalising a home purchase.

1. Title Deed

The Title Deed is the most important property document. It legally proves who owns the property.

Before purchasing a home, ensure that:

• The seller’s name matches the name on the Title Deed.
• The property description (size, survey number, boundaries and address) is accurate.
• There are no disputes or claims attached to the property.

Why is it required?

Without a clear and valid title, you cannot legally claim ownership of the property. Banks will also refuse to provide a home loan if the title is unclear. It is advisable to have a property lawyer verify the authenticity of the Title Deed and confirm that it is free from legal defects.

2. Sale Deed

The Sale Deed is the final agreement executed between the buyer and seller. It officially transfers ownership once it is registered with the local sub registrar’s office.

The Sale Deed includes:

• Sale price and payment details
• Property description
• Date of transfer
• Signatures of the buyer and seller
• Witness signatures

Why is it required?
Only a registered Sale Deed legally transfers ownership. If the Sale Deed is not properly registered, the transaction may not be legally valid. This document becomes your primary proof of ownership after purchase.

3. Encumbrance Certificate (EC)- Check for Liabilities

An Encumbrance Certificate (EC) serves as proof of whether a property has any registered financial or legal liabilities attached to it. It provides a record of all registered transactions related to the property for a specified period.

It includes details of:

• Existing home loans
• Mortgages created in favour of banks or lenders
• Registered legal disputes
• Claims, charges or other financial obligations on the property

Why is it required?

Before buying a property, it is important to ensure that it is not burdened by unpaid loans or legal claims. If the seller has taken a loan against the property and has not repaid it, the lender may still have a legal right over it. This can create serious complications for the buyer.

The EC helps confirm that the property is free from such financial obligations. As a precaution, it is advisable to verify the encumbrance record for at least the last 15–20 years to ensure a clear and secure ownership history.

4. Mother Deed-Ownership History

The Mother Deed is a foundational document that traces the complete ownership history of a property. It records how the property has been transferred from one owner to another over the years through sale, inheritance, gift, partition or other legal means.

Why is it required?
This document helps confirm that the seller has a legitimate right to sell the property. If there is any break in the chain of ownership, it could lead to future disputes. Verifying at least 20-30 years of ownership history is considered safe practice.

5. Approved Building Plan-Construction Legality

The Approved Building Plan is a document sanctioned by the local municipal or development authority, confirming that the property has been constructed in accordance with prescribed building rules, zoning regulations and safety standards.

It contains details such as:

• Structural layout of the building
• Floor plans and design specifications
• Plot area and building dimensions
• Official approval stamp and signature of the competent authority

Why is it required?

Purchasing a property with an unapproved or deviated construction can expose the buyer to legal and financial risks. Unauthorised structures may attract penalties, demolition notices or complications in obtaining a home loan or selling the property in the future.

6. Completion Certificate (CC)

A Completion Certificate (CC) is issued by the local municipal or development authority after inspecting the property and confirming that the construction has been completed in accordance with the approved building plan and applicable regulations.

Why is it required?

It confirms that the building complies with safety norms and legal requirements. Banks often require it for loan approval, and without it, the property may be treated as unauthorised. It also protects the buyer from future legal complications or penalties. 

7. Occupancy Certificate (OC)

The Occupancy Certificate allows residents to legally occupy the building. It is issued after confirming that the property is ready to move in and meets safety standards. Living in a property without an Occupancy Certificate can create long-term legal and financial issues.

Why is it required?

Without a valid Occupancy Certificate, the property does not have official approval for residential use.

• You may face difficulty getting water and electricity connections.
• The property could be considered illegal for residence.
• Resale may become complicated.

8. Property Tax Receipts

Request the seller to provide the latest property tax receipts issued by the local municipal authority. These receipts confirm that property taxes have been regularly paid.

Why is it required?
This ensures there are no pending tax dues. If taxes are unpaid, the liability may pass on to you after purchase. Regular payment of property tax also confirms that the property is registered in municipal records.

9. Khata Certificate 

In certain states, a Khata Certificate serves as proof that the property is duly recorded in the records of the local municipal authority. It confirms that the property details, including ownership and assessment, are officially recognised for taxation purposes. Without a valid Khata, legal and financial transactions related to the property can become complicated.

Why is it required?

It is necessary for:

• Payment of property tax
• Applying for home loans
• Obtaining building plan approvals or permissions
• Smooth resale or transfer of the property

10. No Objection Certificate (NOC)

If the property is located in a housing society or apartment complex, it is essential to obtain a No Objection Certificate (NOC) from the society or residents’ association before completing the purchase.

Why is it required?

The Society NOC confirms that the association has no objection to the transfer of ownership. It also certifies that the seller has cleared all outstanding maintenance charges, dues or other payments payable to the society.

Without a valid NOC, the transfer process may be delayed, and the buyer could face difficulties in getting the property formally recognised by the association.

11. RERA Registration (For Under-Construction Projects)

For under-construction properties, verify whether the project is registered under the Real Estate Regulatory Authority (RERA).

Why is it required?
RERA protects buyers by ensuring transparency in project timelines, approvals, and builder commitments. You can check project details on the official RERA website of your state.

12. Seller’s Identity Proof

Verify the identity and address proof of the seller, such as:

• Aadhaar card
• PAN card
• Passport

Why is it required?
This prevents identity fraud and ensures that the person selling the property is the rightful owner.

13. Power of Attorney 

If the property is being sold by someone other than the registered owner, it is essential to verify the Power of Attorney (POA) authorising the person to act on the owner’s behalf.

Ensure that:

• The POA is properly executed and registered (where required)
• It is valid and has not been revoked or expired
• It clearly grants the authority to sell and execute the sale deed

Why is it required?

If the Power of Attorney is invalid, unregistered, expired, or cancelled, the entire property transaction can become legally problematic. Checking it properly ensures that the person selling the property has the legal right to do so and helps protect you from future ownership disputes or legal issues.

14. Agreement to Sell

Before executing the final Sale Deed, the buyer and seller typically sign an Agreement to Sell. This is a preliminary document that records the agreed terms of the transaction. It outlines the following:

• Agreed sale price
• Payment schedule and mode of payment
• Expected date of possession
• Key terms and conditions
• Penalties or consequences in case either party fails to fulfil the agreement

Why is it required?

The Agreement to Sell provides clarity and legal protection to both the buyer and the seller before the final ownership transfer takes place. It clearly defines the financial commitments and responsibilities of both parties, reducing the risk of misunderstandings or disputes.

Financial Documents to Verify Before Buying a Home

Apart from legal and ownership records, verifying financial documents is equally important while purchasing a home. These documents confirm that all payments related to the property are properly recorded and that any loan associated with the purchase is legally sanctioned. Clear financial documentation ensures transparency, prevents disputes and protects you from future tax or legal complications.

Key Financial Documents to Check:

• Home Loan Sanction Letter: A document issued by the bank confirming the approved loan amount, interest rate, and key loan terms.
• Loan Agreement Copy: The signed contract between you and the bank detailing repayment terms, tenure, interest rate, and other conditions.
• EMI Payment Statements: Records showing the monthly instalments paid towards the home loan.
• Down Payment Receipts: Proof of the initial amount paid by you to the seller before or at the time of purchase.
• Builder or Seller Payment Receipts: Official receipts confirming all payments made to the builder or seller.
• Bank Statements Reflecting Transactions: Statements showing the transfer of funds related to the property purchase for financial transparency.

Important:
Always make payments through official banking channels such as cheque, NEFT, or RTGS to maintain a clear transaction record. Avoid cash payments wherever possible. Ensure every receipt clearly mentions the property details and amount paid, and keep both physical and digital copies of all financial documents for future reference.
