E-signature law
Electronic Signature Laws in the United Kingdom
Yes. UK law recognizes electronic signatures for most commercial contracts governed by English law.
Last verified July 1, 2026
Governing law
Electronic Communications Act 2000 (ECA 2000) and the eIDAS Regulation (retained in UK law as UK eIDAS post-Brexit)
Enacted: 2000
Key sections
- ECA 2000 s.7 (electronic signatures)
- UK eIDAS Arts. 3, 25, 26 (retained)
The UK retained eIDAS post-Brexit as UK eIDAS. WoltSign provides Simple Electronic Signatures (SES). For contracts requiring Advanced (AdES) or Qualified (QES) signatures, including certain regulated financial and legal documents, verify the requirement with UK legal counsel. The Law Commission's 2019 report confirmed that simple electronic signatures are valid for most English law contracts. Scotland, Northern Ireland, and Wales may have specific variations.
What the law requires
- The signature must be uniquely linked to the signatory
- The signature must be capable of identifying the signatory
- The signature must be created using data that is under the signatory's sole control
- Any alteration to the data after signing must be detectable
- For Advanced Electronic Signatures (AdES): meets enhanced identity requirements
Documents that may still require a wet signature
This list is not exhaustive. When in doubt, consult a licensed attorney in the jurisdiction.
- Deeds (require wet ink signature and witness under English and Welsh law. See Law Commission guidance)
- Wills (require wet ink signature in England and Wales under the Wills Act 1837, with limited exceptions)
- Land Registry documents (specific requirements. Check HMLR guidance)
- Some court documents (governed by court procedural rules)
How WoltSign addresses these requirements
WoltSign captures the elements that most e-signature laws require for enforceability: the signer's intent to sign (shown by their action of typing or drawing a signature), their consent to conduct the transaction electronically (captured at the start of each signing session), attribution (the email address and IP address associated with each signature event), and an unaltered record of the signed document with a tamper-evident audit trail.
WoltSign is designed to support the general requirements of ESIGN and UETA. Whether a specific signing session produces an enforceable signature depends on the facts of that transaction, the document type, and the applicable law. No e-signature tool can guarantee a legal outcome.

FAQ
Frequently asked questions
Short answers to the questions teams ask most often about this topic.
Are electronic signatures legally valid in the UK?
Yes. The Electronic Communications Act 2000 and the retained UK eIDAS regulation both recognize electronic signatures. The Law Commission confirmed in 2019 that simple electronic signatures satisfy the legal requirement of a signature for most contracts governed by English law.
What type of electronic signature does WoltSign provide?
WoltSign provides Simple Electronic Signatures (SES), the most widely accepted type under UK and EU law for commercial contracts. Advanced Electronic Signatures (AdES) and Qualified Electronic Signatures (QES) require additional identity verification steps and certified infrastructure that WoltSign does not currently provide.
Can deeds be signed electronically in the UK?
Deeds under English and Welsh law generally require a wet ink signature and a witness under the Law of Property (Miscellaneous Provisions) Act 1989. The Law Commission has proposed reforms but these are not yet law. Do not use simple electronic signatures for deeds without confirming with UK legal counsel.
Does WoltSign work for UK business contracts?
WoltSign's SES-level signatures are suitable for most commercial contracts governed by English law. For regulated industries, financial services documents, or property transactions, verify the specific signature type required with your UK legal team before using WoltSign.
