How to Review a Letter of Intent (LOI) in India: Binding or Not?

A Letter of Intent almost always arrives with a line like "this is not a binding offer, just to confirm our intent to proceed." Treat that sentence as a starting point for analysis, not the answer. Indian courts have said twice at the Supreme Court level, once in 1996 and again in 2021, that an LOI can turn into a binding contract if the words on the page and the parties' conduct show a clear intention to be bound now, whatever the covering letter calls itself. Equally, most LOIs really do stay non-binding on the commercial terms, while specific clauses inside them, confidentiality, exclusivity, costs, governing law, bind you the moment you sign, exactly like in an MoU (link: How to Review an MoU). (Adira, which publishes this guide, makes contract review and CLM software. That is a commercial interest worth naming upfront, but this page is written to be useful on its own, whether or not you ever touch our product.)

This guide walks through how Indian courts test whether an LOI binds you, using the statute and two Supreme Court cases decided 25 years apart, then goes through the mechanics: subject-to-contract language, what typically binds even in a "non-binding" LOI, conditions, validity period, exclusivity, and how to draft your own LOI to land deliberately on whichever side of the binding line you actually want.

What an LOI is, and the two contexts where it shows up

A Letter of Intent records that one party (usually the one with the stronger hand in the deal) intends to proceed with another, before a full contract is negotiated and signed. In India it shows up in two settings that carry very different stakes.

The first is public procurement and tenders. A government department or public sector undertaking runs a tender, picks a winning bidder, and issues an LOI confirming the award, subject to the bidder depositing a performance security, signing an integrity pact, or completing other pre-conditions within a stated window. This is the exact fact pattern in both of the Supreme Court cases below, and it is where most reported Indian LOI litigation comes from.

The second is commercial and M&A deal-making. A buyer sends a target company an LOI (sometimes called a letter of intent to acquire) confirming interest, a rough valuation range, and an intent to proceed to due diligence, ahead of a fuller term sheet or definitive agreement. Here the LOI is usually the very first written document in the deal, earlier and less detailed than an MoU, and mostly a one-way signal from the party making the approach.

The legal test is the same in both settings. What differs is how the pre-conditions are usually built, deposits and integrity pacts in procurement, exclusivity and diligence access in M&A.

The test: intention plus definiteness, not the letterhead

Two things decide whether your LOI binds you: did the parties intend to be bound now (rather than only after a later, fuller contract), and are the terms definite enough for a court to actually enforce them. Both trace back to the Indian Contract Act, 1872.

Section 10 sets out what makes any agreement a contract in the first place, regardless of title:

"All agreements are contracts if they are made by the free consent of parties competent to contract, for a lawful consideration and with a lawful object, and are not hereby expressly declared to be void." Source: Section 10, Indian Contract Act, 1872 (Indian Kanoon)

Section 29 supplies the definiteness half of the test:

"Agreements, the meaning of which is not certain, or capable of being made certain, are void." Source: Section 29, Indian Contract Act, 1872 (Indian Kanoon)

Run your LOI against both. If the price, scope, and key obligations are stated clearly enough that a court could work out what was promised, Section 29 is satisfied. If, on top of that, the words and conduct show the parties meant to be bound now rather than only once a "definitive agreement" is signed later, Section 10 pulls the document into being an enforceable contract, LOI heading or not.

Two Supreme Court cases, 25 years apart, same conclusion

Rajasthan Co-operative Dairy Federation Ltd v Maha Laxmi Mingrate Marketing Service Pvt Ltd, (1996) 10 SCC 405, decided 17 September 1996, is the older and more cited case. The Federation invited applications for selling agents of its "Saras" dairy products and issued an LOI to Maha Laxmi Mingrate on 1 June 1990, on the condition that the company appear on a stated date and furnish a bank guarantee and financial documents. The company missed the date, did not furnish the guarantee, and separately advertised itself as the "sole" selling agent, which it was not. The Federation withdrew the LOI. The Supreme Court held that:

"The Letter of Intent merely expressed an intention to enter into a contract. If the conditions stipulated in the Letter of Intent were not fulfilled by respondent No. 1... there was no binding legal relationship between the appellant and respondent No. 1 at this stage." Source: Rajasthan Co-operative Dairy Federation Ltd v Maha Laxmi Mingrate Marketing Service Pvt Ltd, Supreme Court of India, (1996) 10 SCC 405 (Indian Kanoon)

The company argued unfairness, that it should have been heard before the LOI was pulled. The Court disagreed, precisely because nothing binding had yet formed: no concluded contract meant no natural-justice right to a hearing before withdrawal.

South Eastern Coalfields Ltd v S Kumar's Associates AKM (JV), AIR 2021 SC 3540, decided 23 July 2021, refines the same test for a modern reader. SECL issued a tender for overburden removal, awarded it to S Kumar's Associates, and issued an LOI. The successful bidder never deposited the performance security or signed the integrity pact, SECL re-tendered the work to someone else and then tried to recover the extra cost from the original bidder, treating the LOI as if it were already a binding contract. The Supreme Court held that no concluded contract existed, and set out the general rule and its narrow exception in one line:

"But then the intention to do so must be clear and unambiguous as it takes a deviation from how normally a letter of intent has to be understood." Source: South Eastern Coalfields Ltd v S Kumar's Associates AKM (JV), Supreme Court of India, AIR 2021 SC 3540, 23 July 2021, para 20 (Indian Kanoon)

Read together, the two cases give a working rule: an LOI is presumed non-binding on its core commercial promise unless the document itself shows a clear, unambiguous intention to be bound now. Unmet pre-conditions, deposits not paid, approvals not obtained, are strong evidence the parties did not yet intend to be bound. This is the same intention-plus-definiteness test that decides whether an MoU binds you, applied to a document that usually arrives earlier and thinner in a deal.

"Subject to contract" language: what it actually buys you

Most LOIs carry a line like "this Letter of Intent is subject to the execution of a definitive agreement and creates no binding obligation on either party." That sentence is useful evidence of intent, but it is not a magic word that settles the question by itself. Ctrl+F your LOI for "subject to" and "definitive agreement," then check what surrounds it. If the rest of the document reads as complete, price fixed, scope described in enforceable detail, deadlines binding, a court can still ask whether the parties really meant that "subject to" line, especially once one side has acted on the LOI as if it were final. Rajasthan Co-operative Dairy Federation makes the safer path clear: pair a subject-to-contract statement with real, unmet pre-conditions (deposits, approvals, documentation) rather than relying on the sentence alone.

What binds even inside a "non-binding" LOI

As with an MoU, well-drafted LOIs carve specific clauses out as binding immediately, while the commercial substance waits for the definitive agreement. Check the opening or closing status clause first, it should name exactly what binds.

• Confidentiality. Almost always binding. Bidders and targets routinely exchange sensitive pricing, technical, or financial information at LOI stage, well before any contract is final.
• Exclusivity or no-shop. If the LOI asks you not to negotiate with anyone else for a stated window, that promise is usually binding on its own, functioning exactly like the no-shop clause in a term sheet. Section 27 of the Indian Contract Act voids agreements in restraint of trade, so scope and duration still need to be reasonable, but a time-boxed exclusivity promise tied to one specific deal is standard and enforceable practice, not a restraint-of-trade problem. Full mechanics: No-Shop and Exclusivity Clauses.
• Costs. A clause fixing who pays diligence, legal, or advisory costs if the deal collapses is frequently binding, so a party cannot walk away and leave the other holding the bill. Any pre-fixed number here is capped by Section 74 of the Indian Contract Act at reasonable compensation for actual loss, not the figure written into the clause.
• Governing law and dispute resolution. Often named as binding, since a fight over whether the rest of the LOI binds needs a forum to be resolved in.

Everything else, price, structure, timelines, deliverables, is usually meant to record intent only, pending the definitive contract.

Conditions and validity period

Conditions. Most LOIs, procurement or commercial, make the eventual contract conditional on stated facts: a performance deposit, an integrity pact, board approval, satisfactory due diligence. Sections 31 and 32 of the Indian Contract Act govern contingent contracts, an obligation contingent on an uncertain future event cannot be enforced until that event happens. Both Supreme Court cases above turn on exactly this: the pre-conditions in the LOI were not met, so no contract had yet formed. Vague conditions, "subject to internal approvals" with no owner or date, leave the position genuinely unclear far longer than a specific one does.

Validity period. Check whether the LOI states how long it stays open, "valid for 30 days from issue" is common, after which it lapses automatically unless extended or converted into a definitive agreement. Silence is a real problem: an LOI with no expiry can sit alive indefinitely, keeping any binding exclusivity or cost obligations running long after either side has moved on.

Red flags

Normal	Red flag	Why it matters
Status clause names exactly which clauses bind (confidentiality, exclusivity, costs)	"This LOI is not binding" stated with no list of exceptions	Rajasthan Co-operative Dairy Federation and South Eastern Coalfields both show courts still look at substance and conduct, not the bare label
Pre-conditions are specific, with a deadline and a named owner (deposit amount, document, date)	Vague "subject to satisfactory due diligence" with no deadline	Sections 31-32 hinge on the condition being real and checkable; a vague condition muddies whether the contract has formed
LOI states a fixed validity period (commonly 15 to 30 days for procurement, 30 to 60 for M&A)	No expiry stated, or "until superseded by a definitive agreement"	Any binding exclusivity or cost clause can run indefinitely with no natural end date
Recipient has not yet acted materially on the LOI (no deposit paid, no exclusivity honoured)	Recipient has already spent money, hired staff, or turned away other options in reliance	Reliance and part-performance push a document toward being read as binding, whatever the label says
Withdrawal mechanism is stated: on notice, or automatically if conditions are not met by the deadline	No withdrawal mechanism; unclear what happens if pre-conditions simply are not met	Ambiguity here becomes the actual dispute, as it did in Rajasthan Co-operative Dairy Federation
Exclusivity scope and duration are narrow and tied to this one deal	Open-ended or unreasonably broad exclusivity, no end date	Section 27 voids unreasonable restraints of trade; broad or perpetual exclusivity risks being struck down or ignored
Signatory has clear authority to bind the organisation	Signed by someone without evident authority, no board or management approval referenced	An LOI signed without authority may not bind the organisation regardless of its wording

Bad clause, better clause

Bad (common in a first-draft procurement or M&A LOI): "This Letter of Intent confirms our intent to proceed with the proposed transaction. A definitive agreement will follow. This LOI is not binding on either party."

What is wrong: no named exceptions, no pre-conditions with deadlines, no validity period, no withdrawal mechanism. If the recipient starts incurring costs or holding off other options in reliance on this letter, the bare "not binding" line does very little once a dispute reaches court, exactly the gap Rajasthan Co-operative Dairy Federation and South Eastern Coalfields were decided to close.

Better: "This Letter of Intent records the parties' non-binding intention to proceed toward a definitive [purchase / services / supply] agreement, save that Clauses 5 (Confidentiality), 7 (Exclusivity), and 10 (Costs) shall be binding on both parties from the date of this letter. This LOI, and any exclusivity granted under Clause 7, shall automatically lapse 30 days from the date of issue unless extended in writing or superseded by a definitive agreement. Proceeding to a definitive agreement is conditional on: (a) the Recipient furnishing a performance deposit of [amount] by [date]; (b) execution of the attached Integrity Pact by [date]; (c) satisfactory completion of due diligence by [date]. Either party may withdraw this Letter of Intent on written notice at any time before a definitive agreement is signed, without affecting rights already accrued under Clauses 5, 7, and 10."

What changed: binding clauses are named instead of relying on a blanket "not binding" label, a 30-day validity period stops the letter living forever, each condition has an owner and a date instead of open-ended language, and the withdrawal right is explicit, tracking exactly what both Supreme Court cases treated as decisive.

How to keep an LOI deliberately non-binding, or make it deliberately binding

If you want your LOI to stay non-binding: state the "not binding" line, then back it with real, specific, unmet conditions (a deposit, an approval, a diligence outcome) rather than the sentence alone, keep a short, hard expiry date, and avoid any language that reads as a final commitment on price or scope, which is exactly what tipped both cases toward "no contract yet."

If you actually want your LOI to bind on a specific promise, exclusivity being the most common: name that clause explicitly as binding "with immediate effect," give it its own defined term, and consider having it independently signed or initialled, so there is no argument later that the "non-binding" umbrella swallowed it.

How this interacts with related documents

An LOI is often the first document in a deal, not the only one. It commonly gets followed by a more detailed MoU once both sides have talked further, which typically uses the identical binding-clause pattern, confidentiality, exclusivity, and costs carved out as binding, everything else non-binding, but with fuller commercial terms. Full walkthrough: How to Review a Memorandum of Understanding. Where the LOI's binding promise is exclusivity, that clause is doing exactly the same job as the no-shop clause in a fundraising term sheet, restraining one side from shopping the deal elsewhere for a fixed window. Full mechanics, including how Indian courts have enforced it: No-Shop and Exclusivity Clauses. Whatever binds in the LOI, confidentiality and exclusivity most often, usually reappears in fuller form in whatever definitive agreement follows.

US and global contrast

US and English courts ask a similar question, did the parties objectively intend to be bound, with "subject to contract" treated as strong, though not conclusive, evidence against binding intent in both systems. The practical stakes have historically run higher in the US: in Texaco Inc. v Pennzoil Co. (Texas, 1987), a "memorandum of agreement" over an oil company acquisition was found by a Texas jury to reflect real binding intent, and Texaco ended up paying Pennzoil roughly three billion dollars after interfering with it, a figure that reshaped how American dealmakers treat any preliminary document. India reaches similar caution through statute and two Supreme Court judgments rather than a jury verdict, Sections 10 and 29 of the Contract Act plus Rajasthan Co-operative Dairy Federation and South Eastern Coalfields do the same work: the letterhead never settles the question, the pre-conditions and the parties' conduct do.

FAQ

Is a Letter of Intent legally binding in India? Usually not on its core commercial promise, unless the document shows a clear, unambiguous intention to be bound now, per South Eastern Coalfields Ltd v S Kumar's Associates AKM (JV) (2021). Specific clauses, most commonly confidentiality, exclusivity, and costs, are often carved out as binding immediately, even while the rest of the LOI stays non-binding pending a definitive agreement.

What is the difference between an LOI and an MoU in India? Mostly timing and detail, not legal category. An LOI typically comes first and is thinner, often a one-way signal that one party intends to proceed. An MoU usually follows, is more detailed, and is sometimes signed by both sides as a joint record of understanding. Both are tested the same way under Sections 10 and 29 of the Contract Act. Full comparison: How to Review an MoU.

Can the issuer withdraw an LOI if I have not met the stated conditions? Yes. Rajasthan Co-operative Dairy Federation Ltd v Maha Laxmi Mingrate Marketing Service Pvt Ltd (1996) held that where the recipient had not fulfilled the conditions stipulated in the LOI, no binding relationship existed yet, so the issuer could withdraw without owing the recipient a hearing first.

Does writing "this LOI is not binding" protect the issuer completely? Partly, but not on its own. It is strong evidence of intent, but South Eastern Coalfields confirms courts still look for a clear, unambiguous statement plus surrounding conduct. Pair the sentence with real, specific, dated pre-conditions rather than relying on the words alone.

How long should an LOI stay valid before it lapses? There is no fixed statutory number. Procurement LOIs commonly run 15 to 30 days, tied to when the pre-conditions (deposit, integrity pact) must be met; commercial and M&A LOIs often run 30 to 60 days, tied to when due diligence or a term sheet is expected. What matters more than the exact figure is stating one at all, since an LOI with no expiry can leave a binding exclusivity clause running indefinitely.

Should an LOI be stamped like a regular contract? If it creates enforceable obligations, a binding exclusivity or cost clause in particular, treat it cautiously as an instrument that may attract stamp duty like any other agreement. Rates and treatment vary by state, so check the applicable state stamp legislation, or ask a lawyer, before relying on an LOI with real commercial weight behind it.

This guide gets you to a working understanding of how Indian courts decide whether a Letter of Intent binds you, and how to draft one that lands clearly on whichever side of that line you actually want. It does not tell you whether your specific LOI, as drafted, will be read as binding or non-binding in a dispute, that depends on the exact wording, the unmet or met conditions, and how the parties behaved after signing, which is not something a guide can assess for you. Talk to a lawyer before you sign an LOI you intend to rely on, or before you assume one is safely non-binding.
