Legal validity

Are electronic signatures legally binding

Yes, electronic signatures are legally binding for most business contracts. In the United States the ESIGN Act and UETA give them the same effect as handwritten signatures, and in the European Union eIDAS forbids rejecting a signature only because it is electronic. A few documents, such as wills and some court and family matters, are excluded.

The laws

What each law actually says

A short summary for business readers. It is general information, not legal advice for your situation.

ESIGN Act, United States

The federal Electronic Signatures in Global and National Commerce Act (2000) says a signature, contract or record in interstate and foreign commerce cannot be denied legal effect only because it is electronic. For consumers it adds disclosure rules: they must consent to electronic records and be told how to get paper copies.

UETA, US states

The Uniform Electronic Transactions Act is adopted by 49 states, the District of Columbia and US territories. New York applies its own Electronic Signatures and Records Act with the same effect. UETA applies when the parties agree to transact electronically, which can be shown by their conduct.

eIDAS, European Union

Regulation 910/2014 defines three levels: simple, advanced and qualified electronic signatures. None can be refused as evidence just for being electronic. Only a qualified signature automatically has the same effect as a handwritten one in every member state.

Simple, advanced and qualified signatures compared

What it is

Simple (SES): Any electronic sign of intent, such as a typed or drawn name or a click on sign
Advanced (AES): Uniquely linked to the signer, under their sole control, and any later change is detectable
Qualified (QES): An advanced signature made with a qualified device and a qualified certificate from a trust service provider

Identity check

Simple (SES): Usually email
Advanced (AES): Stronger link to the signer, for example email plus a second factor or identity check
Qualified (QES): Verified identity, often in person or by video

Typical use

Simple (SES): Sales contracts, NDAs, order forms, SOWs, HR letters
Advanced (AES): Higher value or regulated agreements
Qualified (QES): Documents where national law requires a handwritten equivalent

Signee

Simple (SES): Yes, with consent, email authentication and audit trail certificate
Advanced (AES): Supports the evidence an AES relies on (signer link, tamper evident seal); whether a signature qualifies depends on the facts
Qualified (QES): No. Use a qualified trust service provider

In practice most business agreements are signed with simple electronic signatures. What makes them hold up is not the label but the evidence: who received the document, that they agreed to sign electronically, when they signed and that the document has not changed since. That is exactly what the electronic signature software in Signee records, and the electronic signature security page explains how the record is protected.

Documents that still need ink or a qualified signature

Both US laws carve out a short list of documents, and EU member states keep their own lists. Typical exclusions are:

wills, codicils and testamentary trusts
adoption, divorce and other family law matters
court orders, notices and official court documents
notices of utility shutoff, foreclosure, eviction or cancellation of health or life insurance
in many EU countries, real estate transfers and documents that need a notary

If a document falls into one of these groups, or if the other party or a regulator asks for a qualified signature, use the required method for that document. Everything else your business signs every week, from order forms to NDAs, can go through Signee.

What makes an e-signature hold up

Courts look for intent to sign, consent to do business electronically, a clear link between the signature and the signer, and a record that the document was not changed. Signee shows the consent text before signing, sends each signer a unique link, records every step in a hash chained audit trail and seals the final PDF. More background is on our contract management blog, and the rest of the product is described on the contract management software overview.

Consent to electronic records

Shown to every signer before signing

Signed

I agree to receive and sign this agreement electronically, and I understand that my electronic signature has the same effect as my handwritten signature.

I can ask for a paper copy and withdraw this consent at any time by writing to the sender.

Legal validity questions

Are electronic signatures legally binding in the US

Yes, for most contracts. The ESIGN Act and UETA give electronic signatures and records the same legal effect as paper, as long as the parties agree to transact electronically and the record can be kept and reproduced.

Are electronic signatures valid in the EU and UK

Yes. Under eIDAS an electronic signature cannot be denied effect as evidence only because it is electronic. The UK kept the same principle after leaving the EU through its own eIDAS rules and the Electronic Communications Act.

Is a signature from Signee a qualified electronic signature

No. Signee provides simple electronic signatures backed by consent, email authentication and a tamper evident audit trail. Where a qualified signature is required, use a qualified trust service provider.

Is a typed name a valid signature

It can be. Both ESIGN and eIDAS accept many forms of signature. What matters is that the signer intended to sign and that you can prove who signed and what they signed.

Which documents cannot be signed electronically

Common exclusions are wills, family law matters, court documents, certain utility and insurance notices and, in many EU countries, real estate transfers and notarial deeds.

Is this page legal advice

No. It is general information to help you understand the rules. Signee is not a law firm. For a specific document or jurisdiction, ask a qualified lawyer.
