The legal details, minus the complexity
Sign documents with confidence using legally binding eSignatures backed by UK and international law. From secure audit trails to trusted signing standards, everything you need to know about the legal side of using Signable is right here.
Are Signable eSignatures legally binding?
Electronic signatures created with Signable are legally binding in the UK and across most of the world. UK law recognises electronic signatures under several regulations, including:
- Electronic Communications Act 2000
- UK eIDAS Regulation (electronic identification and trust services)
Together, these laws and regulations confirm that electronic signatures are valid and admissible as evidence in court.
For an electronic signature to be enforceable, the same basic principles as any contract apply:
- Intent: the signer intended to sign the document
- Consent: all parties agree to sign electronically
- Integrity: the signed document can’t be altered afterwards
- Audit trail: there’s a record of who signed and when


The importance of the audit trail
The audit trail is what turns an eSignature into legally defensible evidence. It provides a complete, tamper-proof record of who signed the document, and when.
What’s included in the audit trail?
- Unique document fingerprinting to detect any changes
- Signer identity data and activity logs
- IP address tracking for location verification
- Timestamped events for every step in the signing process
Every completed document is issued with a tamper-evident certificate, attached directly to the final PDF.
Choosing the right eSignature level
Under eIDAS regulations, electronic signatures are split into three tiers, each offering increasing levels of security and verification. Think of it as a scale: the higher the level, the stronger the identity assurance.
Qualified Electronic Signature (QES)
The highest level of eSignature security, with signer identity verified by a certified provider. Best suited to highly regulated or high-value agreements where extra assurance is needed.
Advanced Electronic Signature (AES)
A more secure type of eSignature that adds extra identity verification, such as two-factor authentication and tamper-evident signing. Ideal for regulated industries or documents that need additional assurance.
Simple Electronic Signature (SES)
A quick and straightforward way to sign documents online. Suitable for most everyday business agreements, with minimal friction for signers.
Everything you need to sign with confidence

Using Signable across borders is straightforward. Most countries recognise electronic signatures as legally binding under legislation such as the UETA and the ESIGN Act in the United States.
