Your client wants to sign a shareholders' agreement tonight. They're in Glasgow, you're in Birmingham, and the deal needs to close before the bank holiday. Is an electronic signature enough? Does it need witnessing? Will HMRC accept it?
Most commercial documents in the UK can be signed electronically without ceremony. A handful — deeds especially — need extra care. Here's the line.
The default position
Under English law, an electronic signature is generally valid for contracts. The Law Commission confirmed this in its 2019 report, and the Electronic Communications Act 2000 supports the position. For a simple contract — services agreement, NDA, employment contract — typing a name, drawing a signature, or using sign PDF is enough provided the signer intends to authenticate the document.
Deeds: the tricky bit
Deeds require witnessing. The witness must be present (physically or, since 2020 guidance, by live video link in some cases), see the signing in real time, and sign themselves shortly after. Pure asynchronous signing — sign now, witness later from a screen recording — doesn't satisfy the requirement. For most deeds, in-person witnessing remains the safe default.
Audit trails matter
What separates a defensible e-signature from a typed name is the audit trail. Sign PDF captures who signed, when, from what IP address, and which fields they filled. If the signature is ever challenged, the audit trail is your evidence. Keep the audit certificate alongside the signed file — never discard it.
Cross-border considerations
If the document touches another jurisdiction (a Scottish counterparty, a US subsidiary, an EU customer), check that jurisdiction's rules too. eIDAS classifies signatures into simple, advanced, and qualified — most commercial work uses simple. For documents going to court in some EU states, a qualified signature carries extra weight.
What to never sign electronically
Wills, lasting powers of attorney, and certain land transactions still require wet ink in England and Wales. If you're not sure whether a document falls into a special category, default to in-person signing and add the audit trail afterwards. The cost of getting it wrong on a will dwarfs the time saved.
FAQ
Is a typed name a valid signature in the UK?
For most commercial contracts, yes — provided the signer intended to authenticate. A drawn or uploaded signature carries more weight if challenged.
Can I e-sign a deed?
Deeds require witnessing. Electronic signing is possible but the witnessing requirement remains — typically the witness must be physically present.
Does HMRC accept e-signed documents?
Yes, for most filings. Specific stamp duty and trust documents may need wet ink — check the specific form's requirements.
What audit trail does Flint provide?
Each signature is recorded with timestamp, IP address, and field-level events. The audit certificate is downloadable alongside the signed PDF.
Most UK contracts can be signed online tonight. Use Flint's sign tool, keep the audit certificate, and only break out the witness for deeds and the special cases. The deal closes before the bank holiday.
