Short answer: yes. Electronic signatures are valid under UK law for ordinary contracts and, with the right formalities, even for deeds. English courts admitted e-signed documents into evidence starting with the Electronic Communications Act 2000, and in 2019 the Law Commission confirmed that an electronic signature is capable in law of executing a document, including a deed. Brexit did not change this.
Three layers of law, none of them fussy about technology
- The Electronic Communications Act 2000. Section 7 makes electronic signatures admissible in evidence in UK legal proceedings. This is the oldest layer and the foundation everything else sits on.
- Retained UK eIDAS. The EU's eIDAS regulation applied directly in the UK before Brexit, and the UK kept its framework afterward as retained law. It defines the familiar ladder of simple, advanced, and qualified electronic signatures. The ladder matters in regulated sectors, but ordinary English contract law has never required any particular rung of it.
- Common law and the Law Commission. English law asks whether the person intended to authenticate the document, not which technology they used. Typing a name at the end of an email can be a signature. The Law Commission's 2019 review restated this and confirmed that statutory signature requirements can generally be met electronically.
Deeds: valid electronically, with witnesses
Deeds are the highest-formality document in English law, needing signature in the presence of a witness who also signs. The Law Commission concluded deeds can be executed with electronic signatures, and since 2020 HM Land Registry has accepted electronically signed deeds under its prescribed signing methods. The witness requirement still bites, though: current guidance treats physical presence by the witness as best practice, and the pandemic-era relaxation that allowed video witnessing was temporary and has lapsed. So a deed can be signed on a screen, but plan for the witness to be in the room.
Where the UK still wants paper
- Wills. The Wills Act 1837 still requires a will to be signed in the physical presence of two witnesses. Temporary rules permitting video witnessing have expired, so a valid UK will remains a wet-ink document.
- Court forms and filings. Courts accept electronic submission through their own portals, but a party e-signing a court document outside those systems is a different question with a conservative answer.
- Regulated transactions. Some FCA-regulated documents and consumer credit processes carry their own execution rules, and individual statutes occasionally demand writing or paper for specific acts. Sector rules, not general e-signature law, control these.
Scotland runs a separate legal system, but the practical outcome is similar: electronic signatures are recognised and enforceable for everyday contracts, with formal documents following their own rules.
Practical takeaway: for NDAs, employment contracts, freelance agreements, sales contracts, and almost everything a business signs daily, an electronic signature binds in the UK exactly as a handwritten one does. Keep the audit trail, and for deeds, bring the witness.
A checklist that travels well
- Make sure the signer intends to sign: a clear final document, not a draft.
- Connect the person to the signature: their own email account, their own device, a confirmation thread.
- Keep the final file untouched after signature, and keep the message that delivered it.
- For deeds, satisfy the witness requirement and follow any sector guidance that applies to the transaction.

Did Brexit change e-signature legality in the UK?
No. The UK kept the eIDAS framework as retained law, so the simple, advanced, and qualified signature categories still exist, and contracts signed electronically before and after Brexit stand on the same footing.
Can deeds be signed electronically in the UK?
Yes. The Law Commission confirmed electronic execution of deeds is possible, and HM Land Registry accepts e-signed deeds under its prescribed methods. The witness requirement remains, and physical presence of the witness is the safe practice since the temporary video-witnessing rules lapsed.
Is a typed name at the end of an email a legal signature in the UK?
It can be. English law focuses on intent to authenticate, and courts have accepted typed names, clicked checkboxes, and pasted signature images as signatures where the surrounding evidence shows a person meant to agree to the document.
