FAQ

1) Are electronic signatures legally valid in the U.S.?

Yes, they are. Electronic signatures are legally enforceable under the federal ESIGN Act and the state-level UETA, which grant e-signatures the same status as handwritten ones. What truly determines validity is whether you meet process requirements such as obtaining clear consent, proving signer attribution, and maintaining accurate, accessible records. Courts consistently look at the integrity of the signing process, not just the technology used.

2) What’s the difference between electronic and digital signatures?

An electronic signature is a broad legal category that includes any electronic action showing intent to sign: typed names, clicks, drawn signatures, and more. A digital signature uses cryptographic keys to generate tamper-evident certificates, making it more resistant to alteration and more suitable for regulated environments. Industries with strict audit expectations, such as life sciences, often prefer digital signatures because they provide stronger technical evidence.

3) Do we need identity verification for every signer?

Identity verification should match the risk level of the transaction, following frameworks like NIST SP 800-63-4. For routine, low-risk agreements such as NDAs or simple approvals, basic methods like email verification are usually sufficient. High-risk workflows: healthcare, finance, contracting, or public sector transactions – benefit from stronger measures like OTP codes, ID document checks, or SSO-backed authentication.

4) Is RON necessary?

Remote Online Notarization (RON) is only required if your workflows involve notarized documents. Many U.S. states now permit RON, and industries like real estate, lending, and insurance increasingly expect it as part of digital closing processes. Always confirm both your state’s notarization rules and the requirements of counterparties such as lenders, underwriters, or government agencies.

5) How does SignNow stand out for SMB & mid-market?

SignNow offers unlimited users on paid plans, which helps teams scale without unpredictable per-seat costs. Its pricing is transparent and avoids the hidden add-ons common with other vendors, while also offering volume discounts for growing organizations. In addition, SignNow provides 24/7 support, strong security documentation, and compliance resources, making it a practical fit for businesses that need enterprise-level features without enterprise-level complexity.
