Introduction
Purchasing a property is one of the largest financial commitments anyone will ever make. Whether it is an apartment in Delhi, a villa in Gurugram, or a new flat in Pune, property transactions generally require a significant amount of documentation. Many buyers tend to overlook some important steps while purchasing a property and focus only on the price, location, and interior designs. One of the most important steps buyers overlook is the verification of documents.
If any of the documents are invalid, you may risk a legal fraternity, disputes about ownership, or even financial loss. In India, there are frequent fraud cases pertaining to the purchase of properties, many of which occur because buyers do not otherwise check the documents. To protect your investment, you must check all legal documents connected to property ownership, as well as approval documents and documents of registration, prior to purchasing the property.
This article will highlight the documents you should check, the importance of each document, and how platforms like Property Aaj can help you explore properties that are safe and verified.
Key Documents to Verify Before Buying Property
1. Sale Deed
The Sale Deed is the most essential legal document establishing ownership of the property.
The Sale Deed is executed after the finalization of the sale.
It must be registered with the local sub-registrar office.
Check that the seller's name is the same name across previous ownership records.
Why should you check it?
It is the main proof of ownership. If the seller does not have a registered sale deed, the property may be owned by someone else not legally recognized.
2. Title Deed (Mother Deed)
The title deed, or mother deed, establishes the ownership history of the property.
It demonstrates how the ownership of the property has been transferred between owners.
It must be clear and free from disputes or litigation pending title issues.
Why should you check it?
It helps establish the seller's title ownership and authority to sell.
3. Encumbrance Certificate (EC)
The Encumbrance Certificate provides evidence or details if the property has any legal lien, loans, mortgage, or claims.
The encumbrance certificate is issued from the local sub-registrar's office.
It covers a specific period of time (generally 12–15 years).
Why should you check it?
It provides confirmation as to whether the property is free from loans or financial liabilities.
4. Khata Certificate / Mutation Certificate
This is particularly critical in cities such as Bangalore and Pune.
Issued by the municipal authorities.
Serves as evidence of the property’s details, such as size and location, and who it belongs to for the purposes of tax.
Why should you check it?
To confirm that the property exists on the official records and is being charged taxes correctly.
5. Property Tax Receipts.
You should always ask the seller for the latest property tax receipts.
This will tell you that there are no property taxes due.
You must also check that the property tax records are in the name of the seller.
Why should you check it?
If there are unpaid property taxes, the buyer could face legal issues in the future.
6. Building Plan Approval.
If you are buying an apartment or villa within a housing society:
You should check if the builder has received the approval from the local municipal corporation.
You should verify that the sanctioned plan matches the actual construction.
Why should you check it?
If the builder has done unauthorized or illegal construction, they could face demolition notices.
7. Occupancy Certificate (OC)
The Occupancy Certificate is issued by local municipal authorities after construction is complete.
Confirms that the building follows approved plans and is ready for occupancy.
Why check it?
Without an OC, the building may not have legal approval for living.
8. Possession Certificate
Issued by the developer when handing over the property to the buyer.
States the date when the buyer takes possession.
Why check it?
Important for determining tax liability and ownership timeline.
9. Allotment Letter (for under-construction property)
If you’re buying a flat in a new project:
The builder issues an Allotment Letter stating the unit details, price, and payment plan.
Why check it?
It acts as proof of your claim until the sale deed is executed.
10. Loan Clearance Certificate (if applicable)
If the seller has taken a home loan:
Ensure they provide a loan clearance or no dues certificate from the bank.
Why check it?
To confirm the property is free from mortgage before you buy it.
11. RERA Registration Certificate
Under the Real Estate (Regulation and Development) Act, 2016, all builders must register projects with RERA.
Check the project’s RERA number on the official state portal.
Why check it?

Some properties require additional NOCs from government departments:
Fire department
Pollution control board
Electricity and water supply departments

13. Sale Agreement
Before the sale deed is registered, a sale agreement is signed.
Contains terms of the sale, payment schedule, and possession date.
Why check it?
It protects the buyer’s rights if disputes arise before registration.
14. Identity Proof of Seller
Always verify the seller’s:
PAN Card / Aadhaar Card
Passport-size photos
Why check it?
