Short answer: in most of the world, yes, for most everyday agreements. Electronic signatures are recognised in law across the United States, the European Union, the United Kingdom and many African countries, among others. The longer answer is in the exceptions, and in the evidence you keep.
This article is general information, not legal advice. Laws change and differ by country and by document; for a specific case, consult a qualified lawyer.
The principle most laws share
Modern e-signature laws are built on two ideas:
- Non-discrimination. A signature or contract may not be denied legal effect solely because it is in electronic form.
- Intent and attribution. What makes a signature count is that the person intended to sign, and that the signature can be attributed to them.
Neither idea requires a particular technology. A typed name, a drawn signature or a click can all be valid signatures if intent and attribution can be shown.
The main frameworks
United States
The ESIGN Act (Electronic Signatures in Global and National Commerce Act, 2000) is federal law giving electronic signatures and records the same legal effect as paper for transactions in interstate and foreign commerce. The Uniform Electronic Transactions Act (UETA), adopted by most states, does the same at state level. Consumer transactions carry extra requirements, such as consent to receive records electronically.
European Union
The eIDAS Regulation ((EU) No 910/2014) defines three levels:
- Simple electronic signature (SES): any electronic data used to sign, such as a typed or drawn signature.
- Advanced electronic signature (AdES): uniquely linked to and capable of identifying the signer, under their sole control, and able to detect later changes.
- Qualified electronic signature (QES): an advanced signature made with a qualified device and certificate. It has the legal effect of a handwritten signature throughout the EU.
No level may be denied legal effect simply for being electronic. Most business contracts use SES; some regulated documents require QES.
United Kingdom
UK law has long accepted electronic signatures under the common law and the Electronic Communications Act 2000. The Law Commission confirmed in 2019 that an electronic signature is generally capable of executing a document where a signature is required, subject to some formalities for deeds.
Africa
Many African countries have e-transaction laws. Ghana's Electronic Transactions Act, 2008 (Act 772) recognises electronic signatures and records. Nigeria's Evidence Act 2011 provides for electronic signatures to be used as evidence, and Kenya, South Africa and others have their own frameworks. Requirements and exceptions vary, so check the specific law.
Documents that are usually excluded
Across jurisdictions, the exceptions look similar. Documents that often still require ink, witnesses, a notary or a qualified signature include:
- wills, codicils and testamentary trusts;
- deeds and transfers of land or property in many places;
- powers of attorney in some jurisdictions;
- certain court orders, notices and filings;
- some family law documents;
- documents that must be notarised or witnessed in person.
What makes an electronic signature hold up
When a signature is disputed, the question is usually not whether e-signatures are legal, but whether this signature can be tied to this person. Evidence that helps:
- An audit trail: when the document was sent, to which address, when it was opened and signed, from which IP address and device.
- A fixed document: a fingerprint (hash) of the signed file showing it has not changed since.
- Deliberate signing: a clear signing step, not a pre-ticked box.
- Delivery of the signed copy to all parties.
Salsox records an append-only audit trail and fingerprints for every document, sends the signed copy to everyone, and gives each completed document a verification code anyone can check. It provides simple electronic signatures with this evidence, not qualified electronic signatures. For documents that legally require a QES or a notary, use a qualified provider or the required formality. The explainer on how electronic signatures work covers the evidence side in more detail.
Frequently asked questions
Are electronic signatures legally binding in the US?
Generally yes. The federal ESIGN Act (2000) and the Uniform Electronic Transactions Act, adopted by most states, give electronic signatures the same legal effect as handwritten ones for most transactions, with listed exceptions such as wills.
Are electronic signatures valid in the EU?
Yes. Under the eIDAS Regulation (EU) No 910/2014, an electronic signature cannot be denied legal effect just because it is electronic. A qualified electronic signature has the same effect as a handwritten one across the EU.
Which documents cannot usually be signed electronically?
Common exceptions include wills, some property deeds and transfers of land, certain court documents and documents that must be notarised or witnessed. The list varies by country.
