Are E-Signed and Click-Through Contracts Valid in India?

Is an electronically signed contract legally valid in India?

Yes. The Indian Contract Act 1872 asks whether there was a lawful offer and acceptance, consideration, capacity and free consent. It does not ask whether the paper was signed in ink. Section 10A of the Information Technology Act 2000 makes the point explicit: where the proposal, acceptance or revocation is expressed electronically, the contract is not unenforceable solely because electronic means were used.

Where some law specifically requires a document to be in writing or signed, sections 4 and 5 of the IT Act step in. Section 4 treats an electronic record as satisfying a requirement of writing if it is accessible for later reference. Section 5 treats a requirement of signature as satisfied by an electronic signature affixed in the manner the Central Government prescribes. So an arbitration agreement, which must be in writing, can be contained in an exchange of emails.

The exceptions are narrow but important. The First Schedule to the IT Act excludes certain documents from all of this, so they still need paper and ink. And a valid contract can still be unenforceable for other reasons: unpaid stamp duty, lack of registration where the Registration Act requires it, or an unfair term a consumer commission strikes down. Those are the points where electronic contracts usually fail, not the signature itself.

What counts as an electronic signature in Indian law?

The IT Act recognises two kinds. A digital signature under section 3 uses asymmetric cryptography and a digital signature certificate issued by a Certifying Authority licensed by the Controller of Certifying Authorities. These are the USB-token signatures used for ROC filings, GST, income tax and tenders. An electronic signature under section 3A is any technique listed in the Second Schedule that meets the reliability tests in that section; the main one in use is eSign, an online service that authenticates the signer through Aadhaar OTP or biometrics, or other e-KYC, through a licensed eSign service provider.

Section 3A treats a signature as reliable if it is uniquely linked to the signer, under the signer's control at the time of signing, and any later alteration to the signature or the document can be detected. Digital signatures and Aadhaar eSign are built to meet those tests, which is why they carry presumptions in court.

Everything else, such as a typed name at the end of an email, a scanned image of a signature pasted into a PDF, a stylus scribble on a tablet, or a click on 'I agree', is not a section 3A electronic signature. That does not make the contract invalid. It means that if the other side denies agreeing, you prove the agreement the ordinary way: by showing who sent what, from which account, at what time, and what happened next.

Signing methods compared

General guidance on how each method stands if the other party later denies the contract.

Does a contract need a signature at all?

Usually not. Most contracts in India can be oral, written without signatures, or formed by conduct. In Trimex International FZE v Vedanta Aluminium (2010), the Supreme Court held that a contract concluded through an exchange of emails was binding even though the formal written agreement was never signed. What matters is whether the parties agreed on the essential terms and intended to be bound.

A signature is evidence that a person agreed to a particular document. Its absence makes proof harder, not the contract void, except where a statute requires a signed writing. Some do: an arbitration agreement must be in writing; a promise to pay a time-barred debt must be written and signed; certain property documents must be signed and registered. For those, use a recognised electronic signature or paper, as the law requires.

In practice, the dispute is rarely 'there was no signature'. It is 'that is not the version I agreed to' or 'I never received it' or 'my employee had no authority'. Choosing a signing method is really about how easily you can answer those three objections two years later.

Are click-wrap and browse-wrap terms binding in India?

Click-wrap terms, where the user must tick a box or click 'I agree' before proceeding, are generally treated as binding, because the user took a clear step showing consent. Indian courts apply ordinary contract principles: was the user given reasonable notice of the terms, could he read them before accepting, and did he do something unambiguous to accept them. A link to terms placed right next to the button, a scroll box, or a checkbox that cannot be pre-ticked all help.

Browse-wrap terms, which claim to bind anyone who uses a website, with a link tucked in the footer, are much weaker. There is no clear act of acceptance, and the user may never have seen them. Businesses that rely on browse-wrap terms for anything important, such as limitation of liability, arbitration or jurisdiction, take a real risk.

Even binding click-wrap terms are subject to the general law. A consumer can challenge an unfair term before a consumer commission. A term that tries to exclude liability for fraud or negligence beyond what the law allows will not be enforced. And an arbitration or jurisdiction clause hidden in standard terms may be read narrowly against the business that drafted it.

The provisions that decide these questions

Which documents cannot be signed electronically in India?

The First Schedule to the IT Act lists the documents the Act does not cover. For these, the paper rules still apply.

• Wills and codicils. A will must be signed by the testator and attested by two witnesses in ink under the Indian Succession Act 1925. An e-signed will is open to challenge as not validly executed.
• Powers of attorney. A power of attorney, especially one used to deal with property or to appear before authorities, should be signed on paper and, where required, notarised or registered.
• Trust deeds. Creation of a trust, particularly one involving immovable property, should be executed on paper.
• Negotiable instruments other than cheques. Promissory notes and bills of exchange stay on paper. Cheques are carved out because electronic cheques and truncated cheques are recognised.
• Contracts for sale or conveyance of immovable property. Agreements to sell and sale deeds are excluded. Leases create an interest in property, and most advisers treat lease deeds the same way; follow the state's registration procedure for them.

Do e-signed agreements need stamp duty?

Yes, wherever the same agreement on paper would. Stamp duty is charged on the instrument, not on the medium, and stamp laws now treat electronic records as instruments. The usual practice is to buy an e-stamp certificate through the Stock Holding Corporation or an authorised centre in the relevant state and attach it to the agreement before signing, or to use an e-sign platform that integrates e-stamping for the states it supports. The duty depends on the type of document and the state's stamp law: Delhi applies the Indian Stamp Act with its own schedule, and Uttar Pradesh and Haryana have their own rates.

Unstamped agreements are not void, but they are inadmissible in evidence until duty and penalty are paid. In the 2023 decision In re Interplay between Arbitration Agreements and the Indian Stamp Act, a seven-judge bench of the Supreme Court held that an arbitration clause in an unstamped agreement is still enforceable for appointing an arbitrator, and stamping can be dealt with later. That helps arbitration, but a party relying on an unstamped contract in a suit still has to pay up before the court will act on it.

Where a business signs hundreds of standard agreements online, it should work out with its advisers which of them attract duty, in which state, and at what rate, rather than discovering the question when it needs to sue. Our post on lease agreements, registration and stamp duty deals with one common case in detail.

How do you prove an e-signed or click-through contract in court?

By producing the electronic record and the evidence of who agreed to it and when. For a document signed with a digital signature certificate or Aadhaar eSign, section 85 of the Bharatiya Sakshya Adhiniyam lets the court presume the parties signed it, and the signature can be verified against the certificate. The other side then has to show something went wrong, such as a stolen token or a compromised OTP.

For everything else, the audit trail does the work. A good e-sign platform records the email address each signing link went to, the IP address and device used, time stamps for viewing and signing, and a hash of the final document, and issues a completion certificate. For click-wrap, keep the version of the terms that was live on the date, the screen flow the user saw, and the log tying the user's account to the click. Without this, a business is left asserting that the user 'must have' accepted the terms.

All of this is electronic evidence and must be proved with a certificate under section 63 of the BSA, given by a person responsible for the system or device. Disputes about the certificate, who signs it and when it must be filed, are common enough to need their own post on section 63 certificates. When Advocate B.K. Singh reads an e-signed contract that the other side is denying, the first thing he asks for is the platform's completion certificate and audit log, not the PDF itself, because the PDF alone shows only what the document says, not who agreed to it.

Click-through terms with consumers: what a commission will strike down

Consumer law adds a layer on top of contract law. The Consumer Protection Act 2019 defines an 'unfair contract' in section 2(46) to include terms that impose excessive security deposits, disproportionate penalties for breach, refusal of early repayment, unilateral termination without cause, assignment to the consumer's detriment, or unreasonable charges. The State Commissions and the National Commission can declare such terms null and void (sections 49(2) and 59(2)). A click on 'I agree' does not protect such a term.

The Central Consumer Protection Authority's guidelines on dark patterns, issued in 2023, also target interface tricks that push users into agreeing: pre-ticked boxes, hidden charges revealed only at checkout, 'confirm-shaming', forced continuity of subscriptions, and similar designs. A click obtained through those patterns is a weak foundation for enforcing terms, and the design itself can attract action. E-commerce entities also have to follow the Consumer Protection (E-Commerce) Rules 2020 on disclosures and grievance redress.

For consumers, the practical message is that a click is not the end of the matter. Refund, cancellation and liability disputes with online sellers often turn on whether the terms were fairly shown and fair in substance. Our post on e-commerce refund complaints explains the route, and our consumer law practice page covers the commissions.

Email, WhatsApp and OTP acceptance

A contract can be formed by email or WhatsApp if one party makes a clear offer and the other clearly accepts it. 'Confirmed, please proceed' in reply to a quotation with price, quantity and delivery terms will usually make a contract. 'Looks good, let's discuss' will not. Courts look at the whole exchange and at what the parties did afterwards: whether goods were dispatched, invoices raised, advances paid.

Who sent the message matters as much as what it says. A message from a company director's verified email is easier to attribute than one from a junior employee's personal phone. Section 11 of the IT Act attributes an electronic record to the person who sent it or to someone authorised to act for him, so authority is the real question when a company denies an employee's WhatsApp commitment.

OTP-based acceptance is common in lending, insurance and telecom. The OTP proves that someone with access to the phone number completed the step; it does not by itself prove that the person read or understood the terms. Lenders must also follow the RBI's digital lending rules, which require a key fact statement and disclosures before the loan is taken. A borrower who says he never saw the terms can test the lender's records on exactly these points.

Setting up e-signing that will hold up in a dispute

For businesses moving their agreements online. The aim is a record you can prove without the other side's cooperation.

1. Sort documents into categories

   List the agreements you sign: vendor, customer, employment, lease, loan, NDA, settlement. Separate those excluded by the First Schedule and those needing registration, which must stay on paper or follow the state's e-registration route.

2. Choose the signature method for each category

   Use Aadhaar eSign or digital signatures for high-value or high-risk agreements, and platform e-signatures with a full audit trail for routine ones. Click-wrap suits standard consumer and user terms.

3. Build stamping into the workflow

   Work out the duty for each category and state, and attach the e-stamp before signing. A signing platform that handles e-stamping for the relevant state saves errors.

4. Check authority on both sides

   Get board resolutions or authority letters for your own signatories, and ask counterparties to confirm theirs, especially where a company is signing through a manager.

5. Keep the audit trail and versions

   Store the completion certificate, the audit log and the final hashed PDF in a system you control. For click-wrap, archive each version of the terms with its effective dates.

6. Plan for proof

   Decide now who in your organisation will give the section 63 BSA certificate if the record is needed in court, and make sure the system can produce the logs in a usable form.

Before you click 'Sign' on someone else's agreement

• Download and read the full document, including any terms incorporated by link.
• Check that the version you are signing is the version you negotiated.
• Note the dispute resolution clause: arbitration seat, governing law and courts.
• Check whether an e-stamp is attached if the document needs one.
• Make sure you are authorised to sign for your company, and that the other signatory is too.
• Save the signed copy and the completion certificate as soon as the process ends.
• Do not e-sign a will, power of attorney, trust deed or property sale agreement.
• If you sign by Aadhaar OTP, read the consent screen; you are authenticating with your identity.

Common disputes over electronic contracts and how they turn

• 'I never received the link.' Answered by the platform's delivery and view logs, and by whether the person acted on the contract afterwards.
• 'Someone else used my OTP or token.' A real defence if there is evidence of compromise; otherwise the presumptions favour the party relying on the signature.
• 'The terms changed after I signed.' Answered by the document hash and the archived version. Businesses that update terms without notice lose this argument.
• 'The employee had no authority.' Turns on authority letters, board resolutions and whether the company accepted the benefit of the contract.
• 'The arbitration clause was hidden.' Click-wrap with the clause in plain view usually binds; a footer link usually does not.
• 'The agreement was not stamped.' The contract survives, but the party relying on it must pay duty and penalty before a court acts on it.

Employment, lending and other special cases

Offer letters and employment agreements are routinely accepted through HR portals or e-sign. That is valid, but the employer should keep the signed copy and every policy the agreement incorporates, as they stood on the date. Disputes over notice periods and bonds often start with an employee saying the clause was never shown to him. Our post on employment agreement clauses covers the substance.

Loan and guarantee documents executed by Aadhaar eSign are widely used by banks and NBFCs. A personal guarantee can be given electronically, but the guarantor should insist on seeing the full document and the key fact statement, because the OTP step is quick and the liability is not. Settlement agreements and NDAs signed electronically are equally valid; for NDAs, see the post on NDA drafting and enforcement.

Registration of property documents is a separate system. Some states allow parts of the registration process online, but presentation and admission of execution before the sub-registrar still follow the Registration Act 1908 and the state's rules. E-signing does not replace that step.

Before you rely on an e-signed contract

The question to ask is not whether electronic contracts are legal, because they are. It is whether you can prove yours, whether it needed stamping or registration, and whether its key clauses would survive a challenge from a consumer or a counterparty. Advocate B.K. Singh's training in computer applications means he reads an audit log the way he reads an order sheet: looking for the gap between what a system recorded and what a party says happened.
