Sale Deed vs. Agreement to Sell: What a Land Buyer Really Gets

This post is for developers and buyers about to pay an advance on land. It explains what each document secures and gives no duty quote.

In short

• An agreement to sell records a proposed sale. A sale deed completes it. Paying an advance under an agreement does not make you the owner.
• In Tamil Nadu, register an agreement to sell property valued at ₹100 or more, even if you do not take possession. Registering the agreement still does not transfer ownership.
• A clean encumbrance certificate (EC) does not prove that no earlier sale agreement exists. It only reports what the registration index holds for the details you searched.
• Mutation is a separate check after registration. It does not replace title analysis.
• If the seller defaults, specific performance is the rule for contracts under the post-2018 framework, but it is not automatic.

Know what each document secures

Section 54 of the Transfer of Property Act separates a sale from a contract for sale. A sale transfers ownership for a price that may be paid, promised or partly paid and partly promised. A contract for sale does not itself create an interest in or charge on the property.

For tangible immovable property valued at ₹100 or more, section 54 requires a registered instrument for the sale. Do not reduce the question to whether the whole price was paid or one registration date. Review the deed’s terms, the seller’s title and authority, and its legal operation, including section 47 of the Registration Act.

Record different things for each. For an agreement: the conditions, advance, completion obligations and default provisions. For a deed: the registered deed, payment evidence, possession and post-registration follow-up. Possession does not settle ownership, so confirm lawful title and possession separately.

A registered deed does not cure an absent ownership interest, forgery, an unauthorised signatory or every competing claim. Keep the title-risk assessment separate from the document checklist.

In Tamil Nadu, register the agreement even without possession

Under the central framework, section 17(1A) concerns contracts relied on for the protection of part performance under section 53A of the Transfer of Property Act. If such a contract is unregistered, it has no effect for that purpose, so check section 17(1A) compliance if you rely on an agreement for section 53A protection. That does not mean every agreement in India must be registered merely because its value exceeds ₹100.

Tamil Nadu added section 17(1)(g) for agreements relating to the sale of immovable property valued at ₹100 or more. This includes agreements without possession. Other states require their own applicability check.

In R. Hemalatha v. Kashthuri, decided on 10 April 2023, the Supreme Court considered this Tamil Nadu amendment. It held that the section 49 proviso still permits an unregistered agreement as evidence of the contract in a suit for specific performance. That exception does not make it a conveyance or remove the registration obligation. Other objections, and the buyer’s entitlement, are still to be decided.

Get a duty calculation for your actual documents

Check the TNREGINET Duty and Fees schedule and the applicable notifications before signing. The Tamil Nadu stamp-duty guide explains the dated rates.

The live schedule could not be independently retrieved, so this post gives no numerical quote. Ask for a calculation for the actual agreement and proposed deed, including the consideration, advance, possession terms, valuation basis and any applicable concession or adjustment.

Do not assume agreement payments are automatically credited at the deed stage, or that adjustment is always prohibited. Ask for the applicable provision and keep the calculation. If a document may be under-stamped, get advice on assessment, impounding, admissibility and correction first.

Do not treat a clean EC as proof of no prior agreement

A Tamil Nadu Encumbrance Certificate is a search of registration records for specified property details and a period. A registered sale agreement may appear in the index; an unregistered commitment will not.

For each parcel:

• use current and historical survey identifiers and the relevant registration jurisdiction;
• compare the result with the deed chain and any known agreement, mortgage or release;
• investigate missing or mismatched entries; a nil result is not conclusive;
• check litigation, possession and acquisition notices through their appropriate sources; and
• refresh the evidence at the milestones agreed with the transaction team.

Record the search details and date. The EC verification workflow helps organise the evidence; it does not guarantee that all competing rights have been found.

Check patta mutation separately after registration

Compare the Patta-Chitta record and A-Register with the deed and survey evidence. A mismatch needs investigation; it does not by itself show that the deed chain is invalid. Neither a matching revenue entry nor a completed mutation replaces the title analysis.

An agreement alone does not establish the ownership transfer needed for mutation. After registration, check whether the transfer has been processed and what action remains. NIC’s Tamil Nilam account describes integration with the registration system and auto-mutation for qualifying cases. So not every buyer must file a separate application.

Keep the completed order or updated extract and follow up on exceptions, subdivision requirements or pending applications through the revenue process. A specific-performance decree also needs advice on its terms and execution; do not assume every decree must itself be registered before any further step.

If the seller defaults, match the relief to the facts

For contracts governed by the post-2018 framework, section 10 of the Specific Relief Act makes specific performance the rule, subject to sections 11(2), 14 and 16. Readiness and willingness, statutory bars, contract terms and limitation still matter, so success is not automatic.

Section 19(b) protects a subsequent transferee for value who paid in good faith without notice of the original contract, so a competing sale needs a factual assessment. Sections 21 and 22 address compensation and additional relief, including possession or refund where applicable.

• Seller refuses to complete: enforceability, your own performance, limitation and the relief sought.
• Seller transfers to someone else: the later buyer’s notice, good faith, value and available relief.
• You hold a registered deed but lack possession: possession, competing interests and appropriate proceedings.
• A government claim or attachment emerges: its legal basis, priority and effect on the transaction.
• You need the advance back: the contract terms and the available refund or compensation claim.

Run these checks before you pay the advance

• Seller’s title and authority: deed chain, succession or entity authority; every interest being sold.
• Agent signing for an owner: power-of-attorney scope, subsistence and formalities.
• Parcel identity: survey number, subdivision, extent, boundaries and access.
• Existing commitments: EC, agreements, mortgages, releases and seller disclosures.
• Revenue records: patta, classification and mutation discrepancies.
• Acquisition or statutory restrictions: notices and confirmation from the competent authority; an A-Register alone does not answer this.
• Intended use: planning, conversion, environmental and other requirements.
• Possession: site inspection and evidence of occupants, tenants or competing use.
• Commercial conditions: tie disbursement and closing to evidence, dates and remedies.

Manage the gap between agreement and deed

At signing, record registration details, payment evidence, conditions, completion dates and how exceptions will be resolved. Have advisers assess any covenant restricting further dealings.

During the gap, refresh the EC and other material checks at agreed milestones and before further disbursement. If a competing dealing or threatened breach appears, get advice promptly on notices, interim relief and the forum. Do not assume the Sub-Registrar offers a standing caveat service that alerts you to every later instrument.

At closing, reconcile the deed schedule, seller authority, current searches, payment, possession and registration evidence. Then confirm mutation status.

The document readiness checker tracks collected and missing documents. Use it with the document verification workflow and your legal and survey review. Ticking off a document does not clear title.

What this means for you

If you run land acquisition for a developer: do not release an advance on an agreement alone. Register it where the state requires, tie each payment to evidence, and refresh the EC before each disbursement.

If you are buying a single plot: an agreement and a receipt are not ownership. Ask for the duty calculation for your actual documents, and do not rely on a clean EC or a matching patta as proof of title.

If you are selling land: keep your deed chain and proof of your authority to sell ready. Where Tamil Nadu requires it, register any agreement to sell.
