Standard eSignature: NDAs, orders, services, procurement, consent forms — broadly enforceable.
Compliance is decided document by document, not platform by platform
A signing platform is not “compliant” in the abstract — each document type carries its own requirements. Most commercial agreements (NDAs, orders, procurement, services) sign electronically with a standard eSignature. A smaller set — real estate deeds in some states, wills, certain court filings, some employment documents — may require witnesses, notarisation, a qualified electronic signature (QES), or specific authentication. This guide maps the common categories and the controls that matter.
At a glance
Witness or notarisation required: real estate transfers (varies by state), wills/trusts, some powers of attorney.
Qualified signature (QES) zone: EU public-sector filings, some regulated employment and financial documents.
Check the governing law of the contract, not just where you sit — cross-border deals inherit multiple rules.
Document-type compliance map
Typical requirements — always verify the specific jurisdiction and version of the law.
| Document type | Signature method | Extra controls to consider | |
|---|---|---|---|
| NDA / confidentiality | Standard eSignature | Identity check optional; log consent | |
| Sales / order forms | Standard eSignature | Clear consent language | |
| Procurement / supplier | Standard eSignature | Approval routing, amount thresholds | |
| Employment / contractor | Standard, or QES where statute requires | Some jurisdictions require specific e-signature rules or written notice | |
| Litigation / court filings | Check court rules; often e-filing + signature | Court-specific e-filing systems and formats | |
| Real estate transfer | Varies by state; often notarisation | Remote online notarisation where allowed | |
| Wills / trusts | Usually NOT accepted electronically | Consult local law; electronic wills are rare exceptions | |
| EU public-sector / regulated | QES preferred or required | Qualified certificate, EU Trusted List provider |
Match the control to the risk
Routine commercial
Email or SMS identity confirmation plus a complete audit trail is proportionate for NDAs, quotes and service agreements.
Elevated risk
High-value procurement, finance and employment documents benefit from stronger identity verification and approval controls.
Regulated or formal
QES, witnesses or notarisation apply where statutes demand them. Confirm the qualified-provider chain on the EU Trusted List or the local equivalent.
Cross-border
The governing law may be the counterparty's. Map requirements for both jurisdictions before choosing the signature method.
A five-point pre-signing checklist
Identify the document class
Commercial, employment, real estate, litigation, regulated — each has its own default.
Check the governing law
Note the jurisdiction in the contract and any statute about that document type.
Choose the signature level
Standard, AES with strong authentication, or QES.
Add witnesses or notarisation where required
Build these steps into the workflow so they cannot be skipped.
Retain the evidence
Signed file, audit trail, identity evidence, timestamps.
Common questions
Most can, with a standard eSignature. A minority — wills, some real estate transfers, certain court filings — have specific formalities. When in doubt, check the statute for that document type.
