Electronic signatures are recognized in law across most of the world. UNCTAD's Global Cyberlaw Tracker records e-transaction legislation in force in 81% of the countries it surveys, and UNCITRAL records 88 States with legislation based on or influenced by its Model Law on Electronic Commerce (1996). The practical question is rarely whether an electronic signature is legal — it is what evidence you can produce if one is challenged, and which document types your jurisdiction excludes. In the United States, the ESIGN Act (2000) and UETA (1999) grant electronic signatures the same legal weight as handwritten ones. In the European Union, the eIDAS Regulation (2014) provides a unified framework across all member states. Similar laws exist in the UK, Canada, Australia, India, Japan, South Korea, Brazil, and dozens more. The key requirements are consistent worldwide: intent to sign, consent to electronic process, identity attribution, and document integrity. SignForge records each of these: a consent workflow, SHA-256 document hashing, ECDSA cryptographic verification, and an immutable audit trail. Every signed document includes a QR code linking to a public verification page where anyone can confirm its authenticity.
These are the facts we capture and store for every signature. Multiple sets the requirements above — whether what we record satisfies them for a given transaction is a legal question that depends on the circumstances.
Consent checkbox captures explicit intent to sign and agreement to electronic process
Full signer identification via email, IP address, user-agent, and timestamps
SHA-256 hashing before and after signing creates tamper-evident document integrity proof
ECDSA P-256 cryptographic signatures provide mathematical non-repudiation
QR code on every signed document links to public verification page

In most of the world, yes. UNCTAD records e-transaction legislation in force in 81% of the countries it surveys, and UNCITRAL records 88 States with law based on or influenced by its Model Law on Electronic Commerce. In the US, the ESIGN Act and UETA explicitly grant e-signatures the same legal standing as handwritten ones; in the EU, the eIDAS Regulation does the same across all member states. The key requirements — intent to sign, consent, identity attribution, and document integrity — are met by SignForge's workflow. Validity is not the same as evidential weight: if a signature is challenged, what matters is the record you can produce, which is why every envelope carries a full audit trail and portable cryptographic proof.
Any signature — electronic or handwritten — can theoretically be challenged. However, electronic signatures often provide stronger evidence than handwritten ones because they include an audit trail with exact timestamps, IP addresses, and device information. SignForge's SHA-256 hashing and ECDSA verification make its signatures significantly harder to dispute.
Most jurisdictions exclude wills and testaments, powers of attorney (in some cases), family law documents (adoption, divorce), court orders, and documents requiring notarization. For all standard business documents — contracts, NDAs, agreements, invoices — electronic signatures are fully valid.
Virtually all developed nations accept electronic signatures. Key laws include ESIGN Act (USA), eIDAS (EU 27 + EEA), Electronic Communications Act (UK), IT Act (India), Electronic Transactions Act (Australia), PIPEDA (Canada), ESCBA (Japan), ESA (South Korea), and Law 14,063 (Brazil).
General information — not legal advice
This page summarizes electronic signature legislation drawn from primary legal sources and international bodies including UNCITRAL and UNCTAD. It is not legal advice and creates no solicitor–client or attorney–client relationship. Laws change, and how they apply depends on the transaction, the parties, and the document type. Before relying on electronic signatures for a regulated, high-value, or cross-border transaction — or for any document type listed as excluded — take advice from qualified counsel in the jurisdiction whose law governs that transaction. That is a separate question from the governing law of your agreement with SignForge, which is set out in our Terms of Service.
