You Took Possession Under an Agreement to Sell, No Registered Sale Deed Yet. Are You Protected?

By S&S Co. Advocates & Solicitors · Published 15 October 2026 · Informational content, not legal advice: see our disclaimer

A buyer pays the full price, signs an agreement to sell, takes possession of the property, and then the seller, or more often the seller's legal heirs years later, turns up claiming the buyer is a trespasser because there is no registered sale deed. This situation is common enough in Indian property practice that it has its own statutory answer, though the answer is narrower than most people assume. Section 53A of the Transfer of Property Act, 1882 can protect such a buyer's possession, but only as a shield in defence, never as a basis to claim ownership or to go to court demanding a declaration of title.

Understanding exactly what Section 53A does and does not do matters because buyers frequently over-rely on it, treating possession under an unregistered agreement as equivalent to ownership. It is not. What follows is the actual scope of the protection, what changed after 2001, and what a buyer in this position should actually do.

What the doctrine of part performance actually protects

Section 53A codifies, in Indian statutory form, the English equitable doctrine of part performance. The idea is straightforward: where a person has taken possession of immovable property in furtherance of a contract to transfer it, and has done something more than merely enter, such as carrying out the terms of the contract or paying all or part of the consideration, the transferor cannot then turn around and enforce rights over the property inconsistent with the terms of that contract, including a right to evict the person in possession.

The protection is defensive only. If the seller, or someone claiming through the seller, sues the buyer for possession or files a suit based on title inconsistent with the agreement, the buyer can raise Section 53A to resist that specific claim. What the buyer cannot do is use Section 53A offensively, for instance by filing a suit for declaration of ownership or title against the world at large. The Supreme Court made this point explicitly in CIT v. Balbir Singh Maini, describing the protection as available only as a right of defence, not as a sword.

This distinction has real consequences. A buyer relying purely on Section 53A cannot get the property mutated in revenue records as owned outright, cannot mortgage it as full owner without disclosing the position, and cannot sell it onward with clean title, because legal ownership has in fact not passed. What has happened is that the buyer's possession has become legally defensible against the specific seller and those claiming through that seller, nothing more.

The conditions that must actually be satisfied

Section 53A has several conjunctive requirements, and missing even one usually defeats the protection. There must be a contract to transfer immovable property for consideration, the contract must be in writing and signed by the transferor or someone on the transferor's behalf, and the terms must be ascertainable with reasonable certainty from the writing itself.

The transferee must have taken possession of the property, or must already have been in possession and continued in it, in furtherance of the contract. The transferee must also have done some act in furtherance of the contract beyond merely taking possession, which usually means having paid the consideration, in full or substantially, or having carried out some other term the contract required. Mere entry onto the land without more is not enough to invoke the section.

Finally, the transferee must have performed or be willing to perform their own part of the contract. A buyer who still owes a substantial part of the price, or who has otherwise defaulted on an obligation under the agreement, has a much weaker claim to the protection, because willingness to perform is itself a condition that has to be shown, not assumed.

What the 2001 amendment actually changed

Before 2001, an agreement to sell did not need to be registered for a buyer to claim the benefit of Section 53A. A written and signed contract on plain paper, coupled with possession and part performance, was enough. The Registration and Other Related Laws (Amendment) Act, 2001 changed this by amending both Section 53A of the Transfer of Property Act and the corresponding provision of the Indian Registration Act, 1908, requiring that the contract itself be registered for Section 53A to apply.

The practical effect is significant for anyone dealing with property today. A buyer relying on an agreement to sell executed after this amendment came into force cannot invoke Section 53A unless that agreement was itself registered, which in most states means paying the applicable stamp duty on the agreement at the time of registration, not merely at the eventual sale deed stage. An unregistered agreement to sell, however detailed and however fully paid up, no longer by itself attracts Section 53A protection for agreements entered into after the amendment.

This is a frequent trap for buyers who assume an agreement to sell plus possession is automatically safe, because that was broadly true before 2001 and remains true for very old transactions predating the amendment. For anything executed since, the absence of registration is a real vulnerability, and buyers should register the agreement to sell itself, not just wait for a sale deed that may be years away.

How this interacts with a suit for specific performance

A buyer who has paid the price and taken possession is usually also entitled to sue for specific performance of the contract, compelling the seller to execute and register the sale deed. Section 53A and a specific performance suit are not alternatives to each other; they serve different purposes. Specific performance converts the buyer's contractual right into actual ownership by compelling the sale deed. Section 53A, by contrast, only protects possession in the meantime and does not by itself get the buyer a registered deed.

A buyer facing a seller who refuses to execute the sale deed, or whose legal heirs dispute the agreement after the seller's death, should not rely on Section 53A as the end of the matter. Filing a suit for specific performance, within the three-year limitation period from the date fixed for performance or from the date of refusal, is the route to actually perfecting title. Section 53A is what keeps the buyer safely in possession while that suit is pending, not a substitute for it.

Buyers who let the limitation period for specific performance lapse, on the assumption that Section 53A possession is permanently sufficient, can find themselves stuck: still in possession, but with no ownership and no live claim to force the sale deed. The two remedies should be pursued together, not one instead of the other.

What a seller or seller's heirs can still do

Section 53A does not stop a seller, or the seller's heirs, from selling or dealing with the property to a third party on paper, since legal title has not passed. What it stops is the seller, or anyone claiming through the seller with notice of the contract, from actually dispossessing the buyer or defeating the buyer's possession inconsistently with the agreement.

This creates genuine risk for a buyer whose seller sells the same property again to a second buyer who was unaware of the first agreement and registers a sale deed first. Whether the first buyer's Section 53A protection survives against that second buyer depends heavily on notice, meaning whether the second buyer had actual or constructive notice of the first agreement and the first buyer's possession at the time of the second transaction. A second buyer who bought in good faith, for value, without notice of the first agreement, and who gets a registered sale deed, can in some situations defeat the first buyer's possession, which is exactly why registering the agreement to sell matters, since registration itself puts the world on constructive notice.

This is also why a buyer in possession under an unregistered or informal arrangement should move quickly to formalise the position, whether through registration of the agreement, a caveat or lis pendens notation once litigation is filed, or an expedited suit for specific performance, rather than treating continued possession as a permanent, self-sustaining form of security.
