1. Title Deed (The Proof of Ownership)
Before diving into the paperwork, you need to understand the concept of a Title Deed. It isn't just one piece of paper; it is the legal concept of rightful ownership. Without a clear title, you don’t own the land, regardless of how much you paid for it.
In India, you generally acquire a "Title" in three ways:
What to Check:
When looking at a Title Deed, verifying the seller is actually the owner is your top priority.
2. Chain Documents (Link Documents)
Often confused with "Channel documents," in Indian real estate, these are called Chain Documents or Link Deeds . This is the history book of the property. It traces the ownership of the land back 30 years.
Why it matters:
If you buy a house from Mr. Sharma, who bought it from Ms. Singh, who bought it from Mr. Gupta—you need the sale deeds for all those transactions.
3. Encumbrance Certificate (EC)
Think of the Encumbrance Certificate (EC) as a "background check" for the property. Issued by the Sub-Registrar’s Office, it reveals if the property has any legal or financial baggage.
What it tells you:
Pro-Tip: Always ask for an EC covering at least the last 13 to 15 years. This ensures the person selling it to you hasn't already mortgaged it to a bank.
4. Occupancy Certificate (OC)
The Occupancy Certificate is the "Passport" for the building. It is issued by the local municipal authorities (like BBMP, BMC, or MCD) once the builder finishes construction.
It confirms that:
The Risk:
In India, moving into a flat without an OC is technically illegal. Without an OC, the municipality can cut your water or power supply at any time, and you cannot legally sell the flat later.
5. Allotment Letter
Before the Sale Deed is registered, the Allotment Letter is your primary proof of booking. It is issued by the builder or housing authority once you pay the booking amount.
What it contains:
Note: While important, an Allotment Letter does not confer full ownership. Only a registered Sale Deed does that.
6. Tax Receipts (Property Tax)
These are the receipts issued by the municipal corporation when the owner pays their property tax (often called "House Tax" or "Khata" payments in some states).
Why they are crucial:
7. Car Parking Allotment Letter
Parking is a major point of conflict in Indian housing societies. Since parking spaces are limited, having a verbal agreement isn't enough. You need it in writing.
What to look for:
8. No Objection Certificate (NOC)
An NOC is essentially a formal "permission slip." It protects you from third parties claiming they weren't consulted.
Common NOCs you need:
9. Mutation Letter (Inteqal / Khata Transfer)
Buying the house is Step 1. Telling the government you bought it is Step 2. That is Mutation.
The Function:
A Sale Deed moves the ownership to you. A Mutation Letter moves the tax responsibility to you. It updates the Revenue Department’s records to show you are the new owner.
Why do it?
10. Land Use Conversion Certificate
This is critical if you are buying land on the outskirts of a city or a farmhouse. In India, land is designated as "Agricultural" by default unless changed.
The Rule:
You cannot build a residential house or commercial complex on Agricultural land legally. The land must be "Converted" for Non-Agricultural (NA) use.
