Are electronic signatures valid for private deals? US, UK and EU
Updated: October 6, 2026
For everyday private agreements such as a used item sale, a rental condition report or a service quote, an electronic signature is generally accepted in the US, the UK and the EU. Here is what the main laws say, where the exceptions are, and what makes an e-signature convincing if it is ever questioned.
United States: ESIGN and UETA
The federal ESIGN Act (2000) and the Uniform Electronic Transactions Act, adopted by almost every state (New York has its own similar law), say that a signature or contract cannot be denied legal effect only because it is electronic. Both parties must agree to do business electronically. Some documents are excluded, such as wills and certain official notices, and vehicle title transfers follow state motor vehicle rules.
United Kingdom
Section 7 of the Electronic Communications Act 2000 makes electronic signatures admissible as evidence, and the Law Commission confirmed in 2019 that an electronic signature can validly sign a document where the signer intends to sign. Deeds and some property documents have extra formalities such as witnessing.
European Union: eIDAS
Under the eIDAS Regulation (EU) No 910/2014, an electronic signature cannot be refused legal effect or as evidence just because it is electronic. eIDAS distinguishes simple, advanced and qualified signatures. Only a qualified signature is automatically equal to a handwritten one; for most private deals a simple signature is fine, but national law may require a specific form for some contracts.
What makes an e-signature convincing
- Clear consent to sign electronically, recorded before signing.
- An audit trail: the signer's name, email, date and time, IP address and device.
- A fingerprint (hash) of the exact content that was signed, so later changes are detectable.
- Both sides able to download the same signed copy.
When to use something else
Wills, deeds, real estate transfers, and anything your local law says needs a notary or a qualified signature. When the stakes are high or you are unsure, ask a local professional.
Frequently asked questions
Is a drawn signature on a phone enough?+
Combined with consent and an audit trail, a drawn or typed signature is a valid simple electronic signature in most private contexts.
Do both sides need an account?+
No law requires that. What matters is identifying the signer and showing they intended to sign.
Not legal advice.
