Are electronic signatures legally binding?
Electronic signatures are recognised across the EU and the United States. The rules differ by jurisdiction and by the sensitivity of the document, so understanding the frameworks matters before you sign.
In most business and legal contexts, an electronic signature carries the same legal effect as a handwritten one. Two mature legal frameworks underpin this: eIDAS in the European Union and the combination of ESIGN and UETA in the United States. Both establish that a document cannot be denied legal validity simply because it was signed electronically.
The EU framework: eIDAS
Regulation (EU) No 910/2014, commonly called eIDAS, applies directly across all EU member states. It defines three tiers of electronic signature, each offering a different level of assurance about who signed and whether the document was altered afterwards.
- Simple Electronic Signature (SES): the baseline, such as a typed name, a scanned signature or a click-to-sign action.
- Advanced Electronic Signature (AES): uniquely linked to the signatory, capable of identifying them, and able to detect any subsequent change to the signed data.
- Qualified Electronic Signature (QES): an AES created with a qualified signature-creation device and backed by a qualified certificate. Under eIDAS it has the equivalent legal effect of a handwritten signature.
The US framework: ESIGN and UETA
The federal ESIGN Act (2000) and the state-level Uniform Electronic Transactions Act (UETA, adopted by nearly every state) together give electronic signatures and records the same enforceability as paper. The core requirements are intent to sign, consent to do business electronically, association of the signature with the record, and retention of an accessible record.
Some document types are excluded or carry extra formalities: wills and testamentary trusts, certain family-law documents, and some property transfers may require wet-ink or notarisation depending on jurisdiction. Confirm local requirements before relying on an e-signature for these categories.
What actually makes a signature defensible
Legal validity is not only about the signature mark itself. If a signature is ever challenged, the evidence around it decides the outcome: who was invited, how their identity was verified, the timestamps, the IP address, and proof that the final document was not altered. A strong audit trail is what turns a signed PDF into court-defensible evidence.
BAScribe captures this evidence automatically and additionally anchors a cryptographic hash of the executed document on a public blockchain, so any party can independently confirm the file has not been changed since signing without having to trust the platform.
Frequently asked questions
Is a typed name a valid electronic signature?
Yes. Under eIDAS a typed name qualifies as a Simple Electronic Signature, and under ESIGN/UETA it can be enforceable provided there is clear intent to sign and consent to transact electronically. Higher-value or higher-risk documents benefit from stronger identity verification.
Which signature level do I need?
For everyday commercial agreements an SES or AES is typically sufficient. QES is required only where law mandates a signature equivalent to handwriting, or where the counterparty demands the highest assurance. Match the level to the legal risk of the document.
Can an electronic signature be challenged in court?
Any signature, wet-ink or electronic, can be disputed. What protects you is the surrounding evidence: identity verification, timestamps, a complete audit trail, and tamper-evidence proving the document was not altered after execution.
