Are electronic signatures valid in the US and UK? A plain guide
What ESIGN, UETA and UK law say about signing a client contract online, the documents that still need ink, and the records worth keeping.
On this page
For ordinary service contracts, yes. In the US, federal law says a contract can't be refused legal effect just because it was signed electronically, and every state except New York has adopted the matching uniform act. In England and Wales, the Law Commission concluded in 2019 that an electronic signature can validly sign a document. A short list of documents still needs more.
The US: ESIGN and UETA
Two laws do the work in the US, and for a client contract they point the same way.
The federal ESIGN Act, 15 U.S.C. 7001, covers transactions in interstate or foreign commerce. Its core sentence is that a signature, contract or other record "may not be denied legal effect, validity, or enforceability solely because it is in electronic form." That reaches most service work, because a client in another state, a card payment or a contract sent by email all touch interstate commerce.
The state-level law is the Uniform Electronic Transactions Act (UETA). According to the New York City Bar, 50 US jurisdictions have adopted it: every state except New York, plus Washington DC, Puerto Rico and the US Virgin Islands. New York has its own law, the Electronic Signatures and Records Act, which applies to transactions inside the state. For interstate and international deals, ESIGN applies there too.
Neither law requires a particular technology. A typed name, a drawn signature or a click on "I agree" can all count, as long as the person meant to sign and the record can be kept and reproduced.
What still needs paper (or more) in the US
ESIGN has a list of exceptions, set out in 15 U.S.C. 7003. The ones a service business might meet are:
- wills, codicils and testamentary trusts;
- adoption, divorce and other family law matters;
- court orders and official court documents;
- notices that cut off utilities, or that start default, repossession, foreclosure or eviction on a primary home;
- notices cancelling health or life insurance;
- product recall notices and documents that must travel with hazardous materials.
None of these are client contracts for design, consulting, coaching, photography or building work. If your work touches one of them (a law firm drafting wills, say), the rules for that document win.
The UK: what the law and the Law Commission say
UK law got there by a different route. The Electronic Communications Act 2000, section 7, says an electronic signature is admissible in evidence on questions about the authenticity and integrity of a communication. It doesn't say every e-signature is valid. It says a court can look at one.
The clearer answer came from the Law Commission's 2019 report on electronic execution of documents. Its conclusion was that an electronic signature can validly execute a document, including a deed, where the person intended to authenticate the document and any formalities are met. A typed name or a click on an "I accept" button is likely to be recognised, and courts take an objective view of all the circumstances. The government's response in March 2020 agreed with that statement of the law.
The report kept one practical limit in place. A deed that needs a witness still needs the witness to be physically present when it's signed, even if both people sign on a screen. Most service contracts are simple contracts, not deeds, so this rarely comes up. Property, some guarantees and powers of attorney are where it does.
Scotland and Northern Ireland have their own rules for some documents. If you sign deeds or land documents there, ask a local solicitor.
Validity is settled. Proof is the real question
The law accepts e-signatures. Disputes are about who signed and what they signed. The Law Commission's objective approach means a court looks at the evidence around the signature, so the record you keep matters more than how the signature looks.
A good signing record answers four questions:
- Who signed? A name, the email address the link went to and, ideally, a one-time code sent to that address.
- When? A timestamp for opening, signing and countersigning.
- What exactly did they sign? A fixed copy of the document as it stood at signing, with a fingerprint (a hash) that shows it hasn't changed since.
- Did they mean to sign? A clear action, such as typing a name and pressing a button that says "Sign", after the full text was shown.
Keep those records for as long as a claim could be brought. In England and Wales a claim on a simple contract usually has six years. Many US states set four to six years for written contracts, so check your own state.
Habits that make e-signed contracts hold up
A few habits close the usual gaps:
- Send the full contract, not a summary. The client should see every clause before the signature box.
- Sign it yourself too. A countersignature shows both sides agreed, and it's what clients expect.
- Lock the document at signing. Any change after that should be a new version or a written change order, signed again.
- Give the client a copy. Send the signed PDF to both parties straight away.
- Name the right party. If the client is a company, the signer should say they sign for it and give their role.
- Keep the excluded list on paper unless a lawyer tells you otherwise.
- Get consent from individual clients. If your client is a consumer rather than a business, ESIGN expects their consent before electronic records replace information the law says must be given in writing. A plain line in your contract saying both sides agree to sign and receive documents electronically covers most service work.

How Delivvo gives every signed contract a record that stands up
Delivvo lets you send a contract, have the client sign it online and keep a full signing record without paying for a separate e-signature tool. Signatures are unlimited on every plan.
The flow looks like this:
- Build or upload the contract. Start from a clause builder template you can edit line by line, or on Business and up, upload your own PDF and place signature and date boxes on it.
- Send it from the client record. The contract can sit next to the quote and the deposit invoice, so the client reads, signs and pays in one visit. You can set a deadline to sign.
- The client signs, typed or drawn. They don't need an account. Delivvo records the signer's name, the time and the device.
- You countersign. Delivvo then locks the document, stores a SHA-256 fingerprint of the signed copy and files an archived PDF with a signing record page.
- Anyone can check it later. Every contract carries a verification code. A client, their lawyer or an auditor can enter it at delivvo.io/verify and compare a file against the original. The file never leaves their device.
If a client asks for a paper copy, the archived PDF prints with its signing record, so the same evidence works on a desk as on a screen.
You can also lock project files until the contract is signed, so work doesn't go out before the paperwork does. Contracts are templates you edit and issue yourself, so have a lawyer look over your standard terms once. See the details on the contracts and e-signatures page.
FAQ
Is a typed name a valid signature in the US?
Usually, yes. ESIGN and UETA don't require a drawn signature or special technology. What matters is that the person meant to sign and the record can be kept and reproduced. The exceptions in 15 U.S.C. 7003 still apply.
Are electronic signatures valid in the UK?
Yes for most documents. The Law Commission's 2019 report concluded that an electronic signature can validly execute a document where the signer intended to authenticate it and any formalities are met. Deeds that need a witness still need that witness present in person.
Can I e-sign a contract with a client in New York?
Yes. New York has its own Electronic Signatures and Records Act instead of UETA, and federal ESIGN covers interstate and international transactions. A client contract signed electronically is treated much as it is elsewhere.
What evidence should I keep for an e-signed contract?
Keep the signed copy, the signer's name and email, timestamps for sending, opening and signing, a fingerprint of the final file and your countersignature. Store it for at least as long as a claim could be brought, often six years.
