Are Electronic Signatures Legal? What the Law Actually Says

You have just been emailed a lease, an NDA, or a job offer, and the sender wants it signed today. Printing, signing with a pen, and scanning it back feels absurd in 2026 — but is a signature you draw on a screen actually worth anything? The short answer for most everyday documents in most major jurisdictions is yes: electronic signatures have had explicit legal recognition for more than two decades.

This article is an informational overview of the main laws — the US ESIGN Act and UETA, and the EU’s eIDAS regulation — plus the document types that are commonly excluded. It is not legal advice; for a specific high-stakes situation, check the law in your jurisdiction or ask a lawyer. When you are ready to sign, Doqnest’s sign tool lets you draw, type, or upload a signature right in your browser.

What counts as an electronic signature?

Legally, an electronic signature is defined very broadly. Under US law it is an electronic sound, symbol, or process attached to or logically associated with a record and executed with the intent to sign. That covers a signature drawn with a mouse or finger, a typed name at the end of a contract, clicking an “I agree” button, and a scanned image of a wet-ink signature placed on a document.

The key ingredients are intent and consent: the signer meant to sign, and the parties agreed to do business electronically. The visual form of the mark matters far less than people assume — which is why typing your name can be just as binding as an elaborate cursive flourish.

The ESIGN Act and UETA: the US framework

In the United States, two laws do the heavy lifting. The federal Electronic Signatures in Global and National Commerce Act (ESIGN Act), signed in 2000, establishes that a contract or signature may not be denied legal effect, validity, or enforceability solely because it is in electronic form. In plain terms: a court cannot throw out your agreement just because it was signed on a screen instead of paper.

Alongside it sits the Uniform Electronic Transactions Act (UETA), a model law adopted by the overwhelming majority of US states, which does the same job at the state level and fills in practical details — when an electronic record is considered sent and received, how errors are handled, and so on. Together, ESIGN and UETA mean that for ordinary commercial and personal documents, an electronic signature carries the same legal weight as ink.

eIDAS: the EU’s three tiers of e-signature

The European Union takes a tiered approach under the eIDAS regulation (in force since 2016), which defines three levels of electronic signature:

Simple electronic signatures — any electronic data attached to other data and used to sign, such as a drawn or typed signature on a PDF. These cannot be denied legal effect merely for being electronic, and they are sufficient for most everyday agreements.
Advanced electronic signatures (AdES) — uniquely linked to the signer, capable of identifying them, and created so that any later change to the document is detectable.
Qualified electronic signatures (QES) — advanced signatures backed by a qualified certificate from a government-supervised provider. A QES is the legal equivalent of a handwritten signature across the entire EU.

Tip: the higher tiers matter mostly for regulated industries and specific statutory requirements. For a freelance contract or an NDA between two companies, a simple electronic signature is what parties actually use.

Documents you can safely sign electronically

The everyday paperwork that makes up almost all signing volume is squarely covered by ESIGN, UETA, and eIDAS. That includes:

Leases and rental agreements — see the walkthrough on signing a lease online.
NDAs and confidentiality agreements.
Sales and service contracts, purchase orders, and invoices.
HR paperwork — offer letters, onboarding forms, policy acknowledgments, timesheets.
Permission slips, waivers, and most consumer agreements.

The exceptions: documents that usually still need ink

Both US and EU frameworks carve out categories where electronic signatures are excluded or where extra formalities (witnesses, notarization, a qualified signature) apply. The commonly excluded documents include wills, trusts, and testamentary documents, certain family-law documents such as adoption and divorce papers, court orders and official court filings, and some notices tied to serious consequences — like utility shutoffs, insurance cancellations, or eviction and foreclosure notices.

These exclusions vary significantly by jurisdiction — some US states have begun recognizing electronic wills, for example, while others have not. If a document falls anywhere near these categories, check your local law or ask a professional before relying on an electronic signature.

What makes an electronic signature hold up

Validity is one question; proving it later is another. If a signature is ever disputed, what matters is evidence of who signed, what they signed, and that they intended to sign it. A few habits strengthen your position: keep the final signed PDF (and the email thread around it), make sure every party receives a copy, and avoid editing the document after signatures are applied.

Doqnest is built for exactly this kind of ESIGN- and eIDAS-compliant everyday signing: you can draw, type, or upload your signature and place it anywhere on the page, entirely in your browser — the document never leaves your device. The mechanics are covered step by step in how to sign a PDF, or you can jump straight into the sign PDF tool.

अक्सर पूछे जाने वाले प्रश्न

Are electronic signatures legally binding in the US?

Yes. The federal ESIGN Act (2000) and state-level UETA give electronic signatures the same legal effect as handwritten ones for most documents, provided the signer intended to sign and the parties agreed to transact electronically. A handful of document types, like wills, are excluded.

Is a typed name a valid signature?

Generally yes. The law defines an electronic signature broadly — a typed name, a drawn signature, or clicking “I agree” can all qualify, as long as it was made with intent to sign. The visual style of the mark is not what makes it binding.

What is the difference between a simple and a qualified electronic signature?

Under the EU’s eIDAS regulation, a simple electronic signature is any electronic signing mark, while a qualified electronic signature is backed by a certificate from a government-supervised provider and is automatically equivalent to a handwritten signature EU-wide. Most everyday contracts only need the simple kind.

Which documents cannot be signed electronically?

Commonly excluded categories include wills and trusts, some family-law documents like adoption or divorce papers, court orders, and certain formal notices. The exact list varies by country and by US state, so check local law for anything in these categories.

Can I sign a PDF electronically for free?

Yes. Open your document in Doqnest’s sign tool, draw, type, or upload your signature, place it on the page, and download the signed PDF. Everything runs in your browser, so the document stays on your device.
