Is a document I signed electronically legally valid in the UK?
For most everyday agreements the answer is yes, and has been for years. The exceptions are specific and important: wills, deeds needing a witness, and some property documents. What counts as a signature, what to keep as evidence, and where to stop and get advice.

Short answer
For ordinary contracts, an electronic signature is capable in law of executing a document provided the person intended to authenticate it and any other formality is met — the Law Commission's conclusion for England and Wales. A typed name, a drawn signature and a clicked accept box can all count. The exceptions matter: a will requires two witnesses physically present, and so does a deed. Video witnessing of wills was a temporary pandemic measure and has expired.
People sign electronically constantly — a delivery screen, an insurance renewal, a tenancy agreement in a browser, a contract sent as a PDF — and then worry retrospectively about whether it counted. The reassuring part is that this has been settled for ordinary agreements for some time: the law asks whether the person intended their mark to authenticate the document, not what physical form the mark took, and the courts have accepted typed names and clicked boxes as satisfying that. The part worth knowing is the short list of documents where form genuinely matters, because those are exactly the documents people most want to deal with remotely, and a mistake there is not a technicality — it can mean the document does nothing at all.

Step by step
- Understand what the law is actually asking.Not whether ink was used, but whether the person signing intended their mark to authenticate the document, and whether any other formality the law requires has been satisfied. That framing is why a typed name at the end of an email can be a valid signature and why a beautifully rendered scanned signature on a deed with no witness is not.
- Know the three levels you will see named, and what they mean in practice.A simple electronic signature is a typed name, a drawn mark, or a click. An advanced one is uniquely linked to the signatory and detects later changes to the document. A qualified one is an advanced signature backed by a certificate from a formally recognised provider. UK law does not generally require the higher levels for ordinary agreements; they matter for evidential strength and for specific regulated processes.
- Recognise the ordinary case, which is most of them.A contract for services, a sales agreement, an employment offer, an insurance document, a settlement, a consent form: all of these can validly be signed electronically, and are, at enormous volume. If nothing in the document or the law requires a witness or a deed, this is where you are.
- Stop when a witness is required.A deed must be signed in the physical presence of a witness who attests the signature. The Law Commission confirmed that an electronic signature can execute a deed, and that the witness must still be physically there — remote video witnessing does not satisfy the requirement. Powers of attorney, some property transfers and some guarantees are executed as deeds, and this is the most commonly misunderstood point in the whole area.
- Treat wills as a separate and stricter case.A will in England and Wales must be signed in the presence of two witnesses present at the same time, who then sign in the presence of the person making the will. A temporary provision allowed this to be done by video link for wills made between January 2020 and January 2024; that provision has expired and the ordinary rules apply again. The catalogue's guide on making a will covers the formalities, and this is a document to get right rather than to be clever about.
- Check the specific requirements for property and court documents.HM Land Registry accepts electronic signatures for certain deeds in defined circumstances, with its own requirements about how the signing is done and evidenced, and those requirements are detailed and specific. Court documents and statements of truth have their own rules. If your document is going to a registry or a court, follow that body's own current guidance rather than a general principle.
- Note where the jurisdictions differ.The Law Commission's report addresses the law of England and Wales. Scotland has its own statutory framework for the formal validity of written documents, with its own rules on subscription and on self-proving documents, and Northern Ireland has its own provisions. Do not assume a rule stated for England applies across the United Kingdom, and take local advice for anything significant.
- Keep the evidence, because that is where disputes are actually decided.The practical question is rarely whether an electronic signature can be valid; it is whether you can show who signed, when, that they intended to, and that the document has not changed since. Keep the completion certificate or audit trail the signing platform produces, the final signed PDF, and the covering emails. Store them where a backup will catch them, not only in the platform's account.
- Use a proper signing service where the document matters.The established platforms produce an audit trail recording the signatories, timestamps, addresses used and the document's integrity, which is exactly the evidence you would want later. For a low-value document a signed PDF is fine; for anything with real consequences the audit trail is worth the small cost. The catalogue's guide on filling in and signing a form on screen covers the mechanics.
- Know when to stop and ask.A will. A transfer of land or property. A power of attorney. A trust deed. Anything being submitted to a registry or a court. Anything of substantial value. In each of those, the cost of taking advice is small against the cost of a document that turns out to have no effect, and the failure is often only discovered when it is too late to correct.
Common mistakes
- Assuming a scanned image of your signature makes a document a deed — The appearance of the signature is not the issue. A deed requires a witness who is physically present, and no image of a signature supplies one.
- Believing video witnessing of a will is still allowed — It was a temporary measure that expired on 31 January 2024. Wills made by video witnessing after that date do not meet the requirements, and the consequence falls on the people left behind.
- Treating a rule from England and Wales as a United Kingdom rule — Scotland and Northern Ireland have their own frameworks for the formal validity of documents. This is the single most common error in general writing on the subject.
- Keeping only the signed PDF and not the audit trail — The PDF shows a signature. The audit trail shows who applied it, when, and that the document has not changed since. In a dispute the second is what does the work.
- Doing something significant on the strength of an article — The general position is settled and the exceptions are exactly where a lot of value sits. For a will, a deed or a property document, a solicitor's fee is small compared with the consequences of getting the execution wrong.
If it doesn't work
You signed a deed electronically with no witness present
Cause: The witnessing requirement was not met — Fix: The document may not have been validly executed. Do not rely on it. Take advice on re-executing it properly — this is usually straightforward to put right if caught early and very difficult to put right later.
A will was witnessed over video after January 2024
Cause: The temporary provision has expired — Fix: Take legal advice promptly and expect to re-execute the will with two witnesses physically present. An invalidly executed will can mean the estate passes under an earlier will or under the intestacy rules.
The other side says your signature was not valid
Cause: A dispute about intention or authenticity rather than about form — Fix: Produce the audit trail, the email chain and the final document. Most challenges are about whether that person signed rather than whether an electronic signature can count, which is why the evidence is what matters.
A registry or authority has rejected an electronically signed document
Cause: That body has its own requirements — Fix: Read their current published requirements rather than general guidance. Registries and courts specify how signing must be done and evidenced, and their rules are more prescriptive than the general law.
You need a wet signature and everyone is remote
Cause: A formality that cannot be met electronically — Fix: Post it, or arrange for the parties and witnesses to be physically together. For a deed the witness must see the signature being made — the catalogue's guides on posting important documents are relevant to getting it there safely.
The signing platform's account was closed and the audit trail is gone
Cause: The evidence lived only in the platform — Fix: Download the completion certificate and the signed document at the time of signing, every time, and file them with your own records. A platform account is not an archive.
Questions people ask
Does a typed name really count as a signature?
It can, for documents that do not require any particular form. The courts in England and Wales have accepted a name typed at the foot of an email and the clicking of an acceptance box as satisfying a statutory signature requirement, where the intention to authenticate was present. The question is always intention rather than appearance.
What is the difference between a contract and a deed?
In broad terms a contract requires something of value to be given by each side, while a deed does not and is instead subject to stricter formalities including witnessing. Deeds are used for transfers of land, powers of attorney and certain guarantees. If you are unsure which you have, that is a good reason to take advice before signing.
Are electronic signatures accepted for a tenancy agreement?
Ordinary assured shorthold tenancy agreements are commonly signed electronically. Longer leases can be deeds with their own formalities, and there are separate statutory requirements about what a landlord must serve and when. The catalogue's tenancy guides cover the wider process.
Do I need a qualified electronic signature?
Almost never for ordinary purposes. UK law does not generally require it, and the mainstream signing platforms produce evidence that is sufficient for the overwhelming majority of documents. Some specific regulated or cross-border processes do specify a higher level, and those will say so.
Is a photograph of a signed page as good as the original?
For many routine purposes organisations accept it. Where an original is required — a registry, a court, some financial processes — a photograph is not the same thing, and you should keep the original safe rather than relying on the copy. The catalogue's guide on backing up important documents covers keeping both.
