The Electronic Signatures in Global and National Commerce Act (ESIGN, 2000) is the federal foundation:
Adopted by 49 states + DC (all except New York, which has its own ESETA):
ZiaSign ensures ESIGN/UETA compliance automatically with every signature, capturing consent acknowledgment, signer identity verification, and tamper-proof audit trails.
The Electronic Identification and Trust Services (eIDAS) regulation is the world's most comprehensive e-signature framework, updated in 2024.
| Tier | Legal Weight | Requirements | ZiaSign Support |
|---|---|---|---|
| SES (Simple) | Admissible as evidence | No specific requirements | Free — unlimited |
| AES (Advanced) | Higher evidentiary value | Uniquely linked to signer, identity verified | Included free |
| QES (Qualified) | Equivalent to handwriting | Qualified certificate + secure device | Available on Pro |
ZiaSign's eIDAS compliance module automatically detects when QES is needed based on document type and signer location, ensuring you never under-sign a contract.

| Challenge | How ZiaSign Solves It |
|---|---|
| Different laws per country | Auto-detection of signer location and applicable law |
| Varying signature requirements | Smart tier selection — SES, AES, or QES as needed |
| Audit trail requirements | Comprehensive evidence — IP, timestamp, device, email, geolocation |
| Document retention rules | Secure cloud storage with configurable retention policies |
| Language barriers | Multi-language signing experience — 12+ languages |

Are e-signatures valid for international contracts? Yes — when both parties' jurisdictions recognize e-signatures (180+ countries), the contract is valid. ZiaSign's audit trail satisfies evidentiary requirements across all major jurisdictions.
Do I need different e-signature software for different countries? No — ZiaSign handles multi-jurisdiction compliance automatically. One platform, global coverage, zero legal headaches.
What happens if a country doesn't recognize e-signatures? Only a handful of countries (Turkmenistan, Chad, a few others) lack e-signature legislation. For these, wet-ink may still be required. ZiaSign will flag when a signer is in a non-recognized jurisdiction.
Can e-signatures be used for employment contracts globally? In most countries, yes. Germany and Austria require QES for employment contracts under eIDAS. ZiaSign automatically escalates to the required signature tier.
What's the strongest legal evidence for an e-signature? A comprehensive audit trail. ZiaSign generates a signed audit certificate with every document, capturing: signer email, IP address, timestamp (UTC), device/browser information, authentication method, and a SHA-256 document hash.
Navigating e-signature laws across 180+ countries shouldn't require a legal team. ZiaSign automates compliance so you can focus on closing deals, not reading regulations.
