How to Make a Valid Digital Signature

TL;DR

A valid digital signature in the United States meets legal requirements under ESIGN and UETA, proves signer intent, and preserves document integrity. Using signNow, users can prepare documents, place signature fields, request signatures, enforce signer authentication, capture an audit trail, and securely store completed files. signNow supports HIPAA, SOC 2, ISO 27001, and other standards, integrates with common business systems, and offers plans starting at $8/user/mo with a 7-day free trial for quick deployment.

What a valid digital signature is

A valid digital signature is an electronic mark that shows someone agreed to the contents of a document, similar to a handwritten signature but applied online. It links the signer to the record, records the signing time, and prevents unseen changes after signing. In practice, platforms like signNow let you upload a PDF, add a signature field, identify the signer, and capture intent and authentication. The platform stores an audit trail and tamper-evident metadata so the signed file is admissible and verifiable under U.S. e-signature laws.

Legal validity and when to use

Digital signatures meet legal standards under ESIGN and UETA when they capture signer intent, consent to do business electronically, and preserve an audit trail. Use signNow when closing remote sales contracts or collecting employee onboarding signatures at scale; it documents intent and secures records for compliance and dispute defense.

Common implementation challenges

• Signer identity mismatches from weak authentication methods can raise legal disputes and slow workflows.
• Poorly prepared documents with missing fields create signature errors and require multiple re-sends.
• Inconsistent retention policies across systems lead to compliance gaps and audit difficulties.
• Limited mobile support or offline access causes delays for field teams and on-site signers.

Who benefits from eSignatures

Organizations of many sizes use electronic signatures to speed approvals, improve accuracy, and reduce paper handling.

• Real Estate teams handling leases, offers, and disclosures for faster closings.
• Healthcare providers collecting patient consents and intake forms while maintaining HIPAA controls.
• Finance and legal teams signing contracts, invoices, and tax documents securely.

FAQs About eSignatures

Frequently asked questions about creating, validating, and troubleshooting digital signatures using signNow, with practical answers for common scenarios.

• Why is my signature not accepted?
  Check that the document has a Signature field and that the signer completed required fields. Confirm the signer used the provided signing link and the same email address. If authentication was required, verify the signer completed the verification step. Resend the document if necessary and review the audit trail to diagnose where the process stopped.
• How do I verify signer identity?
  Choose an authentication method in signNow before sending: email, SMS one-time passcode, or advanced ID checks. For higher risk documents select multi-factor or third-party identity verification. Record the chosen method in the audit trail; store any verification evidence required by compliance policies.
• Can I sign offline or on mobile?
  signNow supports mobile signing and limited offline capture depending on the app and device. Prepare document fields in advance; the app can cache the signing session. When back online, the completed signature and audit data sync to signNow servers and secure storage.
• What if a signer needs to change a field?
  If a signer made an error, use the 'Decline to Sign' or 'Request Changes' options to return the document to the sender. The sender edits the original or prepares a corrected version and re-sends it. Always preserve audit records to track versions and changes.
• How long are records kept?
  Retention depends on your account settings and regulatory requirements. Export and archive signed documents and audit trails per corporate retention policies. signNow supports secure exports to cloud storage for long-term retention and compliance audits.
• Is signNow compliant for healthcare?
  Yes, signNow supports HIPAA compliance when a Business Associate Agreement is in place; use secure account configurations, access controls, and logging to protect PHI during signing workflows.
