Before you sign any agreement or hand over money for a property in India, you must verify and collect a specific set of legal documents. The Registration Act, 1908 requires that every sale of immovable property worth more than one hundred rupees must be registered with the Sub-Registrar (Section 17), and registration is only possible when you have the right documents in order. Missing even one critical document can result in a rejected registration, a disputed title, or a financial loss you may never recover.
Why this matters
Property is the single largest purchase most Indians make in their lifetime. Yet every year, thousands of buyers discover — after paying lakhs or crores — that the property they purchased has a disputed title, an undisclosed mortgage, or missing approvals. The National Consumer Disputes Redressal Commission regularly hears cases where buyers lost their entire investment because they did not verify basic documents before purchase. A proper document checklist protects you from fraud, ensures smooth registration, and gives you a legally enforceable ownership right.
Documents you must collect and verify
1. Title deed (the most important document)
The title deed proves who legally owns the property. This is the registered sale deed, conveyance deed, or gift deed by which the current seller acquired the property. You need to trace the chain of title deeds going back at least 30 years — this is called the "chain of title" or "flow of title."
In practice: Ask the seller to provide all title deeds from the last 30 years. If any link in the chain is missing, the title may be defective. A property lawyer can help you verify the chain by conducting a title search at the Sub-Registrar's office.
Important: Under Section 54 of the Transfer of Property Act, 1882, ownership of immovable property can only be transferred through a registered instrument (sale deed). A mere agreement to sell, power of attorney, or receipt does not transfer ownership.
2. Encumbrance certificate (EC)
An encumbrance certificate shows whether the property has any legal dues, mortgages, or pending litigation for a specified period. You should obtain an EC for at least the last 30 years.
In practice: Apply for an EC at the Sub-Registrar's office where the property is registered, or use the state's online portal. In Tamil Nadu, use tnreginet.gov.in. In Andhra Pradesh, use registration.ap.gov.in. Most states charge a nominal fee of Rs 50-200. Processing takes 3-10 working days.
3. Khata certificate and extract (for Karnataka) / Patta (for Tamil Nadu) / Mutation record
This document shows that the property is recorded in the municipal or revenue records in the seller's name. Different states use different names — Khata in Karnataka, Patta in Tamil Nadu, Mutation entry in Maharashtra and most other states.
In practice: Verify this at the local municipal corporation or the tehsildar's office. If the property is not mutated in the seller's name, it raises a red flag about ownership.
4. Approved building plan and completion certificate
For any built-up property (flat, house, commercial unit), the builder or owner must have an approved building plan from the local municipal authority and a completion certificate (CC) or occupancy certificate (OC) confirming the construction was completed as per the approved plan.
In practice: Without an OC, the municipal authority can declare the construction illegal. You will also face problems getting water, electricity, and sewage connections, and banks may refuse a home loan.
5. RERA registration certificate (for under-construction properties)
Under the Real Estate (Regulation and Development) Act, 2016, every residential project with more than 8 units or land exceeding 500 square metres must be registered with the state RERA authority before the builder can advertise or sell units (Section 3).
In practice: Check the project's RERA registration number on your state's RERA portal. MahaRERA: maharera.maharashtra.gov.in. Karnataka RERA: rera.karnataka.gov.in. UP RERA: up-rera.in. The RERA registration page will show project details, completion timeline, and any complaints filed.
6. Property tax receipts
Ask for property tax receipts for the last 5-10 years. These serve two purposes: they confirm the seller has been paying taxes (reducing the risk of government claims) and they provide independent evidence that the seller has been in possession and control of the property.
In practice: Verify the receipts with the municipal corporation. Outstanding property tax becomes a charge on the property, meaning you could become liable for the seller's unpaid taxes after purchase.
7. No Objection Certificates (NOCs)
Depending on the type of property and its location, you may need NOCs from multiple authorities:
- Society/Association NOC: If the property is in a housing society, the society must issue a no-objection certificate for the transfer.
- Bank NOC: If the seller has an existing home loan, the bank must issue an NOC confirming the loan is fully repaid and the property is released from mortgage.
- Revenue authority NOC: For agricultural land being converted to non-agricultural use.
- Airport/Defence authority NOC: For properties near airports or cantonment areas.
8. Identity and address proof of the seller
Collect copies of the seller's PAN card, Aadhaar card, and at least one other government-issued ID. Under Section 32A of the Registration Act, 1908, the Sub-Registrar must verify the identity and photograph of every person executing the document.
In practice: Cross-check the seller's name on the title deed with their Aadhaar and PAN. Any mismatch in spelling or name must be resolved before registration.
9. Sale agreement (agreement to sell)
Before the final sale deed is executed, both parties typically sign an agreement to sell that specifies the price, payment schedule, possession date, and conditions. This document is governed by the Indian Contract Act, 1872 and the Transfer of Property Act, 1882 (Section 54).
In practice: Get this agreement drafted by a lawyer, not the builder's standard template. Pay attention to clauses about penalty for delay, refund conditions, and what happens if the title turns out to be defective.
10. Power of attorney (if seller is not the owner directly)
If someone other than the owner is selling the property using a power of attorney (POA), exercise extreme caution. Verify that the POA is registered, not revoked, and that the principal (actual owner) is alive and competent.
In practice: The Supreme Court in Suraj Lamp & Industries Pvt. Ltd. v. State of Haryana (2012) held that property sales through GPA (General Power of Attorney) are not legally valid modes of transfer. A GPA sale does not confer title. Always insist on a registered sale deed executed by the actual owner.
What if things go wrong
If the seller cannot produce all documents
Do not proceed with the purchase. A missing document is a warning sign. Ask the seller to obtain the missing documents and provide them before you make any payment beyond a token advance.
If the title is disputed
If your title search reveals any ongoing litigation, mortgage, or competing claim, walk away unless the dispute is fully resolved. Do not rely on the seller's verbal assurance that "the case will be settled."
If registration is refused
The Sub-Registrar can refuse registration under Section 71 of the Registration Act if documents are incomplete, identities are not verified, or stamp duty is not properly paid. You can appeal to the Registrar (District) under Section 72.

Common myths
Myth: If the seller shows you a sale deed, the property is legally theirs. Reality: A sale deed only proves the last transaction. You must verify the entire chain of title for at least 30 years to ensure no prior owner has a competing claim.
Myth: You do not need a lawyer if you are buying from a reputed builder. Reality: Even reputed builders sometimes sell in projects with unclear land titles. RERA cases are full of complaints against large, well-known developers. Always get an independent legal opinion.
Myth: Property tax receipts prove ownership. Reality: Property tax receipts prove that someone is paying taxes — they are evidence of possession, not proof of ownership. A person can pay property tax on land they do not legally own.
Myth: An agreement to sell is as good as a sale deed. Reality: An agreement to sell does not transfer ownership. Under Section 54 of the Transfer of Property Act, only a registered sale deed transfers ownership of immovable property.

Frequently asked questions
How many years of title documents should I check? You should trace the chain of title for at least 30 years. This covers two full limitation periods under the Limitation Act, 1963 (12 years for private property adverse possession claims). Banks typically require a 13-30 year title search before approving home loans.
Can I verify property documents online? Many states now offer online services. You can check encumbrance certificates, registered documents, and property tax records online through state IGRS portals. However, a physical verification at the Sub-Registrar's office is still recommended for properties with a long history.
What if the seller says some documents are lost? The seller should apply for certified copies at the Sub-Registrar's office where the original documents were registered. Under Section 57 of the Registration Act, certified copies of registered documents are admissible as evidence. Do not proceed based on photocopies or uncertified documents.
Should I hire a lawyer even for a small property purchase? Yes. A property lawyer's fee (Rs 5,000-25,000) is a tiny fraction of the property's value and can save you from losses worth lakhs. The lawyer conducts a title search, verifies documents, drafts the sale deed, and attends registration.
Is it safe to buy property from NRIs? Buying from NRIs involves additional documentation requirements — the seller needs an NRI-specific PAN card, tax clearance certificate from the Income Tax Department, and the payment must comply with FEMA (Foreign Exchange Management Act) regulations. Consult both a property lawyer and a chartered accountant.
