FDA 21 CFR Part 11 Compliant Electronic Signatures
Certivo meets FDA 21 CFR Part 11, EU CTR 536/2014, eIDAS, HIPAA, and ALCOA+ requirements for electronic signatures in clinical trials, pharmaceuticals, and life sciences.
E-Signature Legal Framework
Electronic signatures are legally valid in most jurisdictions worldwide. The key is ensuring your e-signature solution meets the specific requirements of your industry and region.
United States
ESIGN Act (2000) and UETA provide federal and state-level recognition of electronic signatures.
FDA 21 CFR Part 11 adds requirements for regulated industries.
European Union
eIDAS Regulation (2014) establishes a legal framework for electronic signatures across all EU member states.
Three tiers: Simple, Advanced, and Qualified electronic signatures.
Global
Most countries recognize electronic signatures through national laws based on UNCITRAL Model Law.
UK, Canada, Australia, Japan, and 60+ countries have e-signature laws.
FDA 21 CFR Part 11
Title 21 Code of Federal Regulations Part 11 establishes the FDA's criteria for electronic records and electronic signatures to be considered trustworthy, reliable, and equivalent to paper records and handwritten signatures.
Key Requirements:
Certivo Implementation: Every signature in Certivo captures a unique signature ID, timestamp, signer identity, IP address, and signing meaning. All actions are logged to an immutable audit trail with SHA-256 hash verification.
21 CFR Part 11 Subparts
Subpart A - General Provisions
Scope and definitions for electronic records and signatures.
Subpart B - Electronic Records
Controls for closed and open systems, signature/record linking, and signature manifestations.
Subpart C - Electronic Signatures
Requirements for signature components, controls, and identification codes/passwords.
Applicable Industries
ESIGN Act Key Provisions
Legal Equivalence
Electronic signatures cannot be denied legal effect solely because they are in electronic form.
Consumer Consent
Consumers must consent to receive records electronically and can withdraw consent at any time.
Record Retention
Electronic records must be accurately retained in a form that can be reproduced for later reference.
Documents NOT Covered by ESIGN
- - Wills, codicils, and testamentary trusts
- - Family law documents (adoption, divorce)
- - Court orders and notices
- - Utility cancellation notices
- - Product recall notices affecting health/safety
ESIGN Act
The Electronic Signatures in Global and National Commerce Act (ESIGN), enacted in 2000, gives electronic signatures the same legal validity as handwritten signatures for most transactions in interstate or foreign commerce.
What ESIGN Establishes:
UETA Compatibility:The Uniform Electronic Transactions Act (UETA) has been adopted by 47 states. ESIGN serves as federal backup where UETA hasn't been enacted.
eIDAS Regulation
The Electronic Identification, Authentication and Trust Services (eIDAS) Regulation (EU 910/2014) provides a legal framework for electronic signatures, seals, timestamps, and other trust services across all EU member states.
Non-Discrimination Principle: Article 25 states that an electronic signature shall not be denied legal effect solely on the grounds that it is in electronic form.
Certivo Classification:Certivo provides Advanced Electronic Signatures (AES) as defined by eIDAS - uniquely linked to and capable of identifying the signatory, created using data under the signatory's sole control, with tamper-evident linking to signed data.
eIDAS Signature Types
Simple Electronic Signature (SES)
Any data in electronic form attached to or associated with other electronic data used to sign.
Example: Typed name, checkbox consent, click-to-sign
Advanced Electronic Signature (AES)
CertivoUniquely linked to signatory, capable of identifying them, created with high confidence data under sole control.
Example: Authenticated signing with audit trail
Qualified Electronic Signature (QES)
AES created by a qualified signature creation device, based on a qualified certificate.
Equivalent to handwritten signature in all EU member states
EU Clinical Trial Regulation 536/2014
The EU CTR establishes requirements for clinical trial documentation, including mandatory 25-year retention periods and archive ownership requirements.
Article 58 - 25-Year Retention
The sponsor and investigator shall retain the clinical trial master file for at least 25 years after the end of the trial.
Certivo: Configurable retention from 2-30 years with automated retention alerts.
Article 58(3) - Archive Owner
Requires designation of a named individual responsible for the archives who can grant access to authorized persons.
Certivo: Archive owner appointment with transfer history audit trail.
Inspection Readiness
Documents must be readily available for inspection by competent authorities upon request.
Certivo: One-click regulatory exports for FDA, MHRA, and EMA.
UK MHRA 2026
Post-Brexit UK regulations mirror EU CTR requirements including 25-year retention for clinical trial documentation.
Certivo: Separate export format for MHRA inspections.
GDPR Compliance
The General Data Protection Regulation requires organizations to maintain records of processing activities and implement appropriate technical measures to protect personal data.
Maintain records of all processing activities involving personal data
Support access requests and data portability requirements
Implement encryption, access controls, and audit logging
Only collect and retain data necessary for stated purposes
Certivo GDPR Features
Article 30 Records Management
Built-in interface to create and maintain processing activity records with legal basis tracking.
Subject Access Request Exports

Common Inspector Questions
How do you ensure only authorized users can sign documents?
Certivo requires user authentication before any signature. Each user has a unique account with email verification. Organizations can require two-factor authentication for signing.
Can you demonstrate the audit trail for a specific document?
Yes. Every document has a complete audit trail showing all actions: creation, views, field entries, signatures, and downloads. Each entry includes timestamp, user identity, IP address, and action details.
How do you verify the integrity of signed documents?
Each signed document includes a SHA-256 hash and Certificate of Completion. Any modification would change the hash, making tampering detectable. The audit trail uses hash-chain verification.
What is your record retention policy?
Configurable from 2-30 years based on regulatory requirements. EU/UK trials default to 25 years per CTR 536/2014 Article 58. All retention changes are logged with reasons.
How do you handle system access when employees leave?
User accounts can be deactivated immediately by organization admins. Deactivation is logged in the audit trail. Historical signatures remain valid and attributable.
