What Is a Wet Signature? And When You Still Need One

A wet signature is your handwritten signature made with a pen on paper, the ink "wet" when it is applied. The term turns up when a form says "wet signature required" or "no electronic signatures". That wording is common and often confusing, because in England and Wales most contracts do not need one any more. This guide explains what counts, what does not, and the handful of documents where you still have to pick up a pen.

What is a wet signature?

A wet signature is a signature you physically write by hand on the original paper document, usually in ink. Anything that is not a pen mark on that paper is, strictly speaking, an electronic signature: a typed name, a tick box, a signature drawn on a screen, or a pasted image of your handwriting.

The word "wet" does not mean the ink must literally be wet, only that the mark was made by hand on paper. "Wet ink signature" and "original signature" are used for the same thing.

Wet signature vs electronic signature

English law is permissive. Electronic signatures are admissible in evidence under the Electronic Communications Act 2000¹, and the Law Commission concluded in 2019 that an electronic signature can be used to execute a document when the signer intends to authenticate it and any other formalities are met². UK law derived from eIDAS adds that an electronic signature cannot be refused just because it is electronic, and that a qualified electronic signature has the same legal effect as a handwritten one³.

	Wet signature	Simple electronic signature	Qualified electronic signature
What it is	Pen on paper	Typed name, drawn or pasted image, click	Created with a qualified certificate and a secure device
Legal effect	Accepted for all documents	Valid for most contracts and forms	Equivalent to handwritten in eIDAS-derived rules3
Typical use	Deeds, wills, lasting powers of attorney	Contracts, consent forms, HR documents	Specialist regulated transactions
Cost	A pen	Free to low	Paid trust service provider

A digitised signature, the cleaned-up image of your handwriting that you paste into a PDF or Word, is a simple electronic signature. It is not a wet signature and not a qualified one.

Is a signed PDF or a photo a wet signature?

This is the question behind most searches. The answer depends on what you hold in your hand:

• The paper you signed with a pen is the wet signature original.
• A scan or phone photo of that paper is a copy. Many recipients accept it, and it carries your handwriting, but the original is the wet one.
• A signature image pasted into a PDF is an electronic signature. The picture looks like ink, but nobody wrote it on that document.
• A signature drawn on a touchscreen is an electronic signature too, even though you used your finger.

When a form says it accepts a "scanned wet signature", it means a scan of the pen-on-paper original. When it says "electronic signature", any of the methods above is usually fine. If you are unsure, the person who asked for the document is the right one to ask. The Law Commission's summary of the rules is on lawcom.gov.uk.

When you still need a wet signature

The law is mostly about formalities, not about ink. These are the main places where a pen on paper, or at least a witness in the room, is still required or practically unavoidable.

Wills

A will must be in writing, signed by the testator (or by someone else in their presence and by their direction), with the signature made or acknowledged in front of two witnesses present at the same time⁴. Do not rely on a pasted image or a remote signature. The wording is in the Wills Act 1837.

Deeds

A deed needs a witness who is physically present when the person signs, even if the signature itself is electronic². So a deed can be signed electronically in principle, but you cannot do it alone over a video call.

Land Registry transactions

HM Land Registry accepts e-signatures on deeds in defined ways, mostly through a conveyancer. The two approaches in its practice guide are scanned wet-ink signature pages (sometimes called the Mercury approach) and conveyancer-certified electronic signatures. Both still need a witness who is physically present with the signer⁵. If you are buying or selling, your solicitor will tell you which applies.

Lasting powers of attorney

GOV.UK says that everyone must sign the same original document and cannot sign copies or use digital signatures, whether you use the paper form or prepare it with the online service⁶. Ask the Office of the Public Guardian or a solicitor how the witnessing works for your case.

Banks, government forms and individual requests

Some banks, landlords, insurers and public bodies simply ask for an original signature. That is their policy, not a legal requirement, but you still have to meet it. Read the instructions on the form, and if it says "wet signature", it means pen and paper.

How to give a wet signature remotely

If you are not in the same place as the other party, the usual routine is:

1. Print the document in full, including all signature pages.
2. Sign with a pen, black or dark blue ink, within the signature area.
3. Get a witness if one is required. The witness must be physically present, not on a video call, and should sign and add their name and address.
4. Scan or photograph the signed pages as a PDF (see our guide to adding a signature to a PDF for when you do not have to print).
5. Email the scan if a copy is accepted, and post the original if the other side needs it.

If you only need a clean image of your signature for later, see how to scan a signature with a transparent background. For documents signed on someone else's behalf, read our guide to the pp signature.

Practical tips for signing in ink

• Use black or dark blue ink. Some forms, including many government ones, specify it, and it photographs better.
• Sign inside the box and do not touch the printed text.
• Use your usual signature, the same one as on your bank and ID documents.
• If you make a mistake, start again on a fresh page rather than crossing out on an important document.
• Keep a copy of what you signed before you post the original.

Which one should you use?

• Standard contract or form without special rules: an electronic signature is generally fine.
• Anything where the instructions say wet ink: follow them, whatever the law would allow.
• Wills, deeds, LPAs, property transfers: follow the formalities and ask a solicitor.

Not legal advice. This article describes the general position in England and Wales as of October 2026. For a specific document, ask the person or body that will receive it, or a solicitor.

Frequently asked questions

What does wet signature mean?

A signature made by hand with a pen on the original paper document, as opposed to a typed, drawn or pasted electronic signature.

Is a scanned signature a wet signature?

No. A scan of a wet signature is a copy. It may be accepted as an electronic signature, but the original is the wet one.

Can I sign a will electronically?

Not safely. The Wills Act 1837 requires a signature in the presence of two witnesses at the same time. Ask a solicitor.

Do I need a wet signature for a contract in England and Wales?

Usually not. Contracts can be signed electronically unless the contract, a statute or the other side requires otherwise.

Is a digitised signature the same as a qualified electronic signature?

No. A digitised signature is an image of your handwriting. A qualified electronic signature needs a qualified certificate from a trust service provider.
