When we built signing into Triplewave, the design was almost provocatively simple: the signer opens a personal link, reads the document, types their name, ticks a consent box. No drawn squiggle, no certificate ceremony. Which raises the question people quite reasonably ask us: is that a real signature?
The short answer is that for most day-to-day business paperwork — service agreements, NDAs, proposals, offer letters — yes, in India and in most of the world. The long answer is more interesting, because it explains when the short answer stops being true.
One thing before we start: this is not legal advice. We're a document company that did its homework, summarizing law as we understand it in August 2026. For anything with real stakes, talk to a lawyer who knows your situation.
Start with what a signature is for
A signature does two jobs: it shows who agreed, and it shows that they agreed. Everything else is ritual.
Indian contract law has always been relaxed about the ritual. Under the Indian Contract Act, 1872, most contracts need offer, acceptance, and consideration — not a signature at all. Businesses have bound themselves by handshake, purchase order, and conduct for a century and a half. The Supreme Court made the electronic version of this explicit in Trimex International v. Vedanta Aluminium (2010): an unconditional acceptance given over email concluded a binding contract, even though the formal agreement was never executed. The emails were the contract.
So the real question is rarely "is a typed name a signature?" It's "if this is ever disputed, can I prove who agreed to what, and when?" That's an evidence question, and it's the lens for everything below.
India: two tracks through the IT Act
The Information Technology Act, 2000 gives electronic agreements two distinct kinds of support, and conflating them causes most of the confusion.
Track one: validity. Section 10A (added by the 2008 amendment) says a contract isn't unenforceable merely because it was formed electronically. Section 5 makes a recognized electronic signature satisfy any law that demands a signature. Together with the Contract Act's indifference to form, this is why click-wraps, email confirmations — and typed-name signatures — can bind.
Track two: statutory signatures. Sections 3 and 3A define the electronic signatures the state formally recognizes: digital signature certificates (the USB-token kind, built on certified public-key cryptography) and, since a 2015 notification, Aadhaar eSign — you authenticate with an OTP sent to your Aadhaar-linked mobile, and a licensed certifying authority issues a certificate and affixes the signature in seconds. These notified methods carry statutory presumptions: in a dispute, the law presumes a secure electronic signature was affixed by the person it names, and the other side must rebut it.
A typed name in a signing box is not on that notified list. Using one means you're standing on track one: the agreement is real, but proving who typed the name is your job, on ordinary evidence. This is precisely why audit trails exist — and why the Bharatiya Sakshya Adhiniyam, 2023 — which replaced the Indian Evidence Act, 1872 on 1 July 2024 — matters to document nerds: its Section 63 (successor to the old Section 65B) governs how electronic records get admitted, certificate and all.
What can't be e-signed at all. The IT Act's First Schedule excludes certain documents from electronic execution entirely: wills and other testamentary dispositions, trust deeds, most powers of attorney, and negotiable instruments other than cheques. Two things worth knowing about that list. First, a 2022 amendment quietly shrank it — contracts for the sale of immovable property came off the excluded list, demand promissory notes became e-signable, and powers of attorney in favour of RBI/SEBI/IRDAI-regulated entities gained a carve-out. That amendment is why your bank's loan stack went fully digital around then. Second, e-signable is not the same as registrable: a property sale deed may now be signed electronically, but registration under the Registration Act, 1908 still means a trip to the sub-registrar.
The US and Europe, briefly
The US settled this early and pragmatically. The federal ESIGN Act (June 2000) and UETA — adopted by 49 states, with New York running its own equivalent, ESRA — make electronic signatures valid if four things hold: intent to sign, consent to do business electronically, a signature logically associated with the record, and a retained copy. Note what's absent: any requirement about how the signature looks. A typed name, a click, a drawn squiggle — all equal in the statute's eyes. The drawn signature box that every tool ships is theater, and the American statutes never asked for it.
The EU's eIDAS Regulation (910/2014) took the opposite approach: three formal tiers. Simple electronic signatures (our typed name) can't be denied legal effect just for being electronic; advanced signatures add cryptographic identity binding; qualified signatures (QES) — certificate-based, issued by audited trust providers — are the only tier automatically equivalent to handwriting across all member states. For ordinary commercial contracts, simple signatures are used everywhere in Europe. But a handful of national-law cases (certain German employment documents are the famous example) demand stronger forms or even paper, so cross-border HR paperwork deserves actual legal review.
What "acknowledgment-grade" means, and why we chose it
We describe Triplewave's signing as acknowledgment-grade, and the term is deliberate — it names both what it is and what it isn't.
When someone signs a Triplewave document, we record the typed name, an explicit consent affirmation, a timestamp, the signer's IP address and browser, and the fact that the link used was a private capability token sent to a specific email. The document locks, and its content hash goes into the record — so what was signed can't quietly drift afterwards. In evidence terms, that bundle answers the useful questions: which document, which version, who was invited, from where and when did they assent.
Here's the opinion, and you're welcome to argue: most business paperwork is over-signed and under-evidenced. A wet-ink scrawl on page 6 of a scan proves almost nothing — signatures get contested as forged, pages get swapped, and the scan says nothing about when anything happened. A boring typed name wrapped in a complete audit trail is better evidence for the ordinary run of commercial disputes, where the fight is over what was agreed, not over cryptographic identity.
And here is what acknowledgment-grade is not for. Reach for Aadhaar eSign, a DSC, or a QES when the statutory presumption is worth having: property and loan documents, anything a regulator will inspect, deals whose value justifies pre-paying for stronger proof, counterparties you have reason to distrust, and any EU document where national law names a tier. And nothing electronic — ours or anyone's — executes an Indian will.
The honest close: signature disputes are rare, and that rarity is what most e-signing products quietly price on. We'd rather you know exactly which track you're standing on before you need to.
Again — not legal advice. Laws summarized as of August 2026; the IT Act's schedules in particular have a habit of moving.
