What is Letter of Intent?

A Letter of Intent (LoI) is a document that sets out the key terms of a proposed deal between two parties, before the full definitive agreement is drafted. It is commonly used in mergers and acquisitions, investment rounds, senior hiring, commercial real estate transactions, and large B2B procurement deals. Think of it as a halfway point between a casual handshake and a fully negotiated contract.

The defining feature of an LoI is that it is almost always a mix of binding and non-binding clauses. The commercial terms (price, valuation, closing date, scope of work) are typically non-binding so that both sides can walk away if due diligence turns up something unexpected. However, specific clauses are expressly binding: confidentiality of shared information, an exclusivity or no-shop period during which the recipient cannot negotiate with other parties, allocation of costs, governing law, and dispute resolution. This structure protects both sides during the gap between the LoI and the final contract.

In Indian M&A practice, LoIs are often accompanied by a non-disclosure agreement and a term sheet. The LoI frames the overall intent, the NDA protects confidential information, and the term sheet captures the specific commercial points. On the hiring side, LoIs are increasingly used for senior leadership roles where the final employment contract takes weeks to finalize but the candidate needs a written commitment before resigning from their current job.

Aadhaar eSign is a natural fit for LoIs because speed matters at this stage. Deals move quickly and printing, couriering, and scheduling signing meetings across cities wastes days. With SignSetu, the proposing party uploads the LoI, adds the recipient as a signer, and both parties sign with Aadhaar OTP from wherever they are.

Sign your letter of intent in 3 simple steps

No printing. No scanning. Just drop your PDF and sign.

1

Upload the LoI PDF

Draft the LoI with clear binding and non-binding language. Save as PDF and drop it into SignSetu.

2

Add both parties as signers

Enter the name and email of the proposing party and the recipient. Each party receives a secure signing link.

3

Both parties verify with Aadhaar OTP

Each party signs independently from their own location. Aadhaar OTP verifies identity. Once both have signed, the final LoI is emailed to both parties.

Essential clauses in a letter of intent

Make sure your letter of intent includes these clauses before you sign.

  • Identification of both parties with authorized signatories
  • Background and purpose of the proposed transaction
  • Proposed commercial terms (price, valuation, scope)
  • Explicit statement of which clauses are binding vs non-binding
  • Confidentiality obligations (drafted as binding)
  • Exclusivity or no-shop period (typically 30, 60, or 90 days)
  • Due diligence access rights
  • Expiry date or sunset clause for the LoI itself
  • Conditions precedent to moving to the definitive agreement
  • Governing law and dispute resolution (drafted as binding)

Common mistakes to avoid

Treating the LoI as purely ceremonial and then discovering that a court holds the commercial terms binding
Forgetting to put a sunset date on the LoI, so the exclusivity period runs forever
Omitting the confidentiality clause, exposing sensitive financial information shared during due diligence
Writing an LoI that duplicates what an NDA and a term sheet already cover
Using loose language like 'approximately' and 'to be decided' for critical numbers
Missing a clear exit clause, making it hard for either party to walk away cleanly

Legal validity of an eSigned letter of intent

Letters of Intent are fully eligible for Aadhaar eSign under Section 3A of the IT Act, 2000. The enforceability of any given LoI depends on the language used, not on how it was signed. Indian courts assess whether the document shows an intention to create legal relations (Section 10 of the Indian Contract Act, 1872) and whether the essential elements of a contract are present. If an LoI uses mandatory language like 'shall' and 'agrees to', and sets out clear obligations with consideration, it will usually be held binding even if it is titled 'Letter of Intent'. Conversely, if the LoI expressly states that it is non-binding except for specific carve-out clauses, Indian courts will respect that. The Supreme Court has repeatedly held that substance prevails over form in contractual interpretation. The practical takeaway: draft the LoI with clear, intentional language about which parts are binding. For LoIs in M&A and investment contexts, confidentiality, exclusivity, and dispute resolution should always be drafted as binding clauses, while the commercial terms should remain non-binding until the definitive agreement is signed. Stamp duty is usually not applicable to non-binding LoIs. LoIs do not require notarization or registration unless they transfer an interest in immovable property, in which case the Registration Act 1908 applies and Aadhaar eSign is not available.

Frequently asked questions

Everything about eSigning your letter of intent in India.

Is a Letter of Intent legally binding in India?
It depends on the language. An LoI drafted with mandatory words like 'shall' and setting out clear obligations with consideration is usually binding under the Indian Contract Act 1872. Most commercial LoIs are drafted as hybrid documents: non-binding on the deal terms, binding on confidentiality, exclusivity, and dispute resolution.
What is the difference between an LoI and an MoU?
Functionally they overlap significantly. An LoI is typically one-sided (written by the proposing party and countersigned by the recipient) and used at the earliest stage of a deal. An MoU is usually mutual and often covers longer-term collaboration. Both can be binding or non-binding based on the language used.
Can I use an LoI for a job offer?
Yes, and it is common for senior leadership hiring. The LoI commits the employer to the role, compensation, and joining date while the full employment contract is being finalized. The candidate can use it to resign from their current job with confidence.
How long is an LoI usually valid?
LoIs should always include a sunset date, typically 30 to 90 days from signing. This gives enough time for due diligence and definitive documentation without locking parties in indefinitely.
Is an eSigned LoI enforceable in court?
Yes. Under Section 3A of the IT Act 2000, Aadhaar eSigned documents have the same legal status as physically signed ones. Enforceability depends on the content of the LoI, not how it was signed.
Do I need to pay stamp duty on an LoI?
Non-binding LoIs usually do not attract stamp duty. If the LoI creates binding financial obligations, your state may charge stamp duty at the agreement rate. Check your state schedule.
Can multiple parties sign a single LoI?
Yes. While traditional LoIs are bilateral, SignSetu supports multi-party signing for deals where three or more parties are involved (for example, a JV with three partners or a consortium bid).
