Legally binding
Under ESIGN, UETA and eIDAS, a properly captured electronic signature carries the same legal weight as a handwritten one for most everyday agreements.
Electronic signatures, explained
Understand e-signatures, then sign with confidence
What electronic signatures are, how they work, where they're legally valid, how to stay safe — and a clear, factual look at the most popular online signing services.

Why they matter
Three reasons electronic signatures replaced the pen
The same agreement, signed in minutes instead of days — with a stronger paper trail than ink ever left behind.
Signed in minutes
No printing, scanning or posting. Send a document, and every party can review and sign from wherever they are — often before the day is out.
Sign on any device
Laptop, tablet or phone — reputable services keep the experience and the resulting record consistent across every screen.
Proof, not just a signature
Every signature leaves an audit trail
Behind the signature, a good e-signature platform records who opened the document, when, from which device and IP address, and in what order everyone signed. That certificate of completion is sealed to the file so any later change is detectable.
It's the part that paper never had — and the reason electronic records often hold up better in a dispute than a scanned wet-ink copy.
How the record is built
Recognised around the world
Valid across borders — within limits
The United States (ESIGN & UETA), the European Union (eIDAS), the United Kingdom, Canada, Australia and dozens of other jurisdictions recognise electronic signatures for the vast majority of agreements.
A short list still needs ink or special handling — wills, certain family-law and property documents, and some notarised instruments. Knowing where the line sits is half of signing well.

How it works
Signing a document in three steps
Every major service follows the same shape, whatever the branding on the buttons.
Upload the document
Add your PDF, Word file or template and mark where signatures, initials and dates belong.
Add signers & fields
Enter each signer's email, set the signing order, and assign the right fields to the right person.
Send, sign & store
Signers get a secure link, sign on any device, and everyone receives the sealed copy with its audit certificate.
The honest picture
Real advantages — and a few things to watch
Electronic signing is faster, cheaper and better-documented than paper. It also introduces new questions about security, identity and lock-in that are worth going in with your eyes open.
Advantages
- Turnaround measured in minutes, not postal days
- No printing, scanning, couriers or physical storage
- A tamper-evident audit trail attached to every file
- Fewer missed fields and lost pages than paper
- Easier to search, back up and share securely
Things to watch
- Identity is only as strong as the authentication you enable
- A handful of document types still require ink or notarisation
- Vendor lock-in and per-envelope limits can add up
- Phishing emails often imitate real signing requests
- Account security (passwords, 2FA) becomes critical
Before you sign anything online, it's worth five minutes on the safety basics — verifying the sender, enabling two-factor authentication and checking the completion certificate. Read the security guide →

Common questions
Electronic signatures, answered
Not quite. “Electronic signature” is the broad legal idea — any electronic mark that shows intent to sign. A “digital signature” is a specific, higher-security technology that uses cryptography and a certificate to verify identity and detect tampering. Every digital signature is an electronic signature, but not the other way around.
In most countries, yes. The US ESIGN Act and UETA, and the EU's eIDAS regulation, give electronic signatures the same legal standing as handwritten ones for the vast majority of agreements, provided intent, consent and a proper record are captured.
Exceptions vary by jurisdiction but commonly include wills and testamentary trusts, certain family-law documents, some property transfers, and documents that require notarisation or a witnessed wet-ink signature. When in doubt, check local rules or ask a lawyer.
Generally no. With most services, signing a document that was sent to you is free — you only pay if you want to send documents for others to sign. Free tiers and trials exist for senders too, with limits on volume or features.
Check the sender's email address, hover over links before clicking, and log in to the service directly rather than through an unexpected email. Reputable platforms never ask for your password by email. Our security guide covers the full checklist.
