Unable to Verify Digital Signature With SignNow
Award-winning eSignature solution
An unable to verify digital signature workflow is an electronic signature process that records who signed, when they signed, and what they approved. In U.S. business use, the goal is to create an attributable, tamper-evident record that supports ESIGN and UETA compliance. SignNow adds audit trails, signer authentication, document history, and retention controls so the completed file can be reviewed later as evidence of intent and execution.
An electronic signature record helps businesses collect approvals faster, reduce manual handling, and keep an evidence trail. Under ESIGN and UETA, it can be legally effective for U.S. transactions when the signer’s intent, attribution, and record integrity are preserved.

How the signing flow works
The process follows a simple sequence from document preparation to archived completion, with each step adding evidence about who signed and when.
Set up the file: Prepare the document and choose the signer route before sending it for review. Send to signers: Deliver the request by email, link, or mobile workflow. Collect the signature: Capture the signer’s action and store the signed record. Complete the record: Seal and archive the file with its audit history.

FAQ and troubleshooting
These answers focus on plan limits, audit evidence, and compliance details that affect how a signature record is reviewed later.
SignNow supports audit trails, signer authentication, templates, and mobile apps across paid plans. If a document is hard to verify, confirm that signer identity, timestamps, and document history are included before export. Those details strengthen attribution under ESIGN and UETA.
The Business plan includes legally binding eSignatures, audit trails, templates, and mobile apps. For higher control needs, Business Premium and Enterprise add bulk send, kiosk mode, advanced signer authentication, and more workflow options. HIPAA use still requires a BAA.
For healthcare records, use a BAA and verify that the workflow preserves access controls, audit logging, and retention. HIPAA does not require a specific signature tool, but it does require safeguards for PHI and record integrity under the Security Rule.
The signed file should include the audit trail, timestamps, signer details, and document history. If any of those elements are missing, the record can be harder to defend in a dispute, even when the underlying signature remains legally valid under ESIGN or UETA.
Mobile signing is valid under ESIGN and UETA when the signer intended to sign the record. SignNow mobile apps support iPhone, iPad, and Android workflows, which helps when signatures are collected away from a desktop.
Use the 7-day free trial to test workflow fit, but remember that paid plans include the controls needed for longer-term document handling, including audit trails and retention features. Enterprise controls and HIPAA support depend on the selected plan and configuration.
Practical ways to reduce risk

Match authentication to risk
Preserve the full audit trail
Align retention with law
Restrict access by role

Privacy and disclosure pitfalls
Signed files can expose personal data, payment details, or health information if teams share links without limiting access or removing unnecessary attachments. Consent capture can fail when organizations do not record the signer’s agreement to electronic delivery, which can weaken the file’s legal record. Access control mistakes can let the wrong team member view, download, or forward a signed document, creating privacy and audit concerns. Unclear sharing permissions can scatter the audit trail across inboxes, drives, and local devices, making later review harder and less reliable.

HR forms, onboarding packets, and policy acknowledgments stay organized for employees, contractors, and managers.
Key features for signed records
The most useful capabilities are the ones that preserve attribution, visibility, and a clear record after the document is signed.
Audit trail
Captures signer activity, timestamps, and document history so teams can review the signing event later without relying on memory or separate email threads.
Mobile access
Supports mobile signing on iOS and Android, which helps users complete signing tasks away from a desk or while working offline.
Data protection
Uses encryption in transit and at rest, helping protect signed documents and their supporting records during transfer and storage.
Reusable workflows
Supports templates and reusable workflows, which reduces manual setup for recurring contracts, HR forms, and consent documents.
Compliance support
Works across regulated use cases with HIPAA, SOC 2 Type II, ISO 27001, and ESIGN and UETA alignment.
Integrations
Connects to business systems so signed documents can move into existing storage, CRM, or ERP workflows without extra handling.

For managed environments, organizations often pair browser access with device policies, SSO, and role-based provisioning. Mobile capture is useful when signers are away from a desk, and offline workflows help when connectivity is limited.

Industry examples and outcomes
These examples show how different teams use signed records, audit evidence, and retention controls in day-to-day operations.
Real estate
A real estate team needs signed lease and closing documents to move quickly across locations.
- Mobile signing helps keep transactions moving.
- Audit trails preserve signer evidence.
SignNow supports faster lease and closing workflows by combining mobile signing, role-based routing, and a documented audit trail. That combination helps real estate teams keep records organized for later review while reducing delays caused by paper handling and in-person scheduling.
Healthcare
Healthcare staff need patient forms and consent records that stay organized, secure, and easy to retrieve.
- HIPAA workflows require BAA-backed controls.
- Audit history supports record retention.
SignNow can support HIPAA-oriented workflows when the organization has a BAA in place and uses its audit history and access controls. That structure helps healthcare teams maintain consent records, preserve evidence, and keep signed forms available for later operational or compliance review.
