Award-winning eSignature solution

What electronic signature validity means

An electronic signature is valid when it identifies the signer, shows intent to sign, and can be linked to the signed record. Under U.S. ESIGN and UETA rules, SignNow helps capture that consent with audit trails, authentication options, and tamper-evident records. That makes it suitable for many business documents, including contracts, HR forms, consent forms, and approvals, while helping teams keep records organized and defensible.

Who uses electronic signatures

Business teams

Teams use electronic signatures for contracts, NDAs, HR forms, and consent documents with clear audit trails.

Regulated sectors

Legal, healthcare, and finance groups use SignNow for regulated workflows and secure approvals.

Business types that benefit most

Different organizations use SignNow to reduce paper handling, preserve evidence, and keep signing workflows aligned with internal approval rules.

  • Solo law offices use SignNow for engagement letters, NDAs, and client approval forms without paper handoffs or repeated in-person meetings.
  • Healthcare clinics use secure signing for patient intake, consent forms, and BAA-supported workflows that need identity checks and record retention.
  • Enterprises use role-based templates, delegated sending, and admin controls to manage high-volume approvals across sales, HR, and operations teams.

These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.

Signer authentication and certificates

PKI:

PKI supports trusted identity chains.

X.509 certificates:

X.509 certificates bind public keys.

SMS OTP:

SMS OTP adds possession checks.

ID verification:

ID verification strengthens signer attribution.

Two-factor authentication:

Two-factor authentication improves access control.

Biometric verification:

Biometric checks raise assurance.

Inside the audit trail

The audit trail records each signing event so the completed file can be traced, reviewed, and defended if needed.

01

Signer authentication:

Log the signer’s identity method, including email, SMS OTP, or ID verification.
02

Timestamp capture:

Capture the exact UTC timestamp for each action in the signing flow.
03

Document hashing:

Hash the document so later edits break signature validation.
04

Tamper-evident sealing:

Seal the file with a tamper-evident record.
05

Event history:

Store the event history with delivery and completion details.
06

Audit export:

Export the audit trail as evidence for review or dispute resolution.

Frequently asked questions

These answers cover signing, verification, compliance, and record-keeping issues that affect whether an electronic signature is valid in practice.

Business and Enterprise plans can support more structured workflows, while the 7-day free trial lets you test sending and signing before upgrading. If a signer cannot open the document, check the invitation link, browser, and authentication settings first.

The audit trail records signer actions, timestamps, and delivery history. If a document is questioned later, export the completed file and audit log together so the record shows who signed, when they signed, and what changed.

For HIPAA workflows, use a BAA and keep PHI in encrypted records with controlled access. SignNow’s security controls support HIPAA-aligned use, but the covered entity still needs internal policies for retention, authorization, and user access.

If a document requires stronger evidence, use SMS OTP or ID verification instead of email-only access. That improves attribution and helps support more sensitive transactions without changing the basic ESIGN and UETA validity framework.

If templates are not appearing for a team member, verify admin permissions and shared template access. SignNow role controls let administrators manage who can send, edit, or reuse templates across teams.

For documents that need long-term records, keep the signed PDF and audit trail under the applicable rule. HIPAA records generally require 6 years under 45 CFR 164.530(j)(2), and other sectors may require different retention periods.

Privacy and disclosure pitfalls

  • Personal data can remain visible in documents if redaction, field design, or permissions are not configured carefully.
  • Consent capture can fail when electronic delivery notices, checkbox language, or signer acknowledgments are missing.
  • Access control mistakes can expose drafts, completed files, or audit logs to users who should not see them.
  • Shared links can be forwarded outside the intended audience if expiration and authentication settings are too weak.

Risks of improper e-signature use

Weak attribution

Signed file rejected in dispute.

No consent record

Missing consent weakens enforceability.

Access breach

Poor access control exposes PHI.

Evidentiary gap

Incomplete audit trail,

Retention failure

Improper retention violates record rules.

Retention and record-keeping

Use retention rules, archive design, and exportable evidence to keep signed records usable after the transaction is complete.

Export the audit trail

Export the full audit trail with each completed document so reviewers can see signer identity, timestamps, and event history together. Keep the export in the same archive as the signed PDF to preserve context.

Archive records securely

Use secure archival storage with access controls, encryption, and clear retention labels. That makes it easier to locate records, prove integrity, and meet sector-specific obligations for healthcare, finance, education, or real estate.

Document the retention rule

Name the governing rule in your retention policy. For HIPAA records, keep material 6 years under 45 CFR 164.530(j)(2); for other industries, document the controlling federal, state, or contract requirement.

Close the record completely

Review file completeness before closing the record. Confirm the signed PDF, audit trail, delivery history, and any consent notices are all present so the record supports later review or discovery without reconstruction.

Sending and signing methods

  1. Use the web app when you need full document preparation, template management, and centralized sending from a desktop browser.
  2. Use the mobile app when signers need to review, sign, or upload documents while away from a desk.
  3. Use kiosk mode for on-site collection, such as reception desks, field offices, or shared tablets with repeated signers.
  4. Use shareable signing links when many external recipients must sign the same document without separate invitations.
