Digital identity has become the cornerstone of modern notarial services, fundamentally transforming how legal professionals verify, authenticate, and certify documents across the UK and Europe. As remote online notarisation gains traction and qualified electronic signatures become standard practice, understanding the role of digital identity in notary services is essential for businesses, legal professionals, and anyone requiring notarised documents.
This comprehensive guide explores how digital identity systems work within notarial frameworks, the regulatory landscape governing these services, and practical implications for UK professionals operating in an increasingly digital legal environment.
Brief summary:
- Five core concepts: Digital identity, identification, authentication, electronic signature, and authentic acts work together under eIDAS regulation for notary services
- eIDAS 2.0 timeline: EUDI Wallet mandatory in all EU states by December 2026, creating unified digital identity infrastructure for cross-border notarisation
- Three signature levels: Simple, advanced, and qualified electronic signatures require progressively stricter identity verification, with only QES accepted for authentic notarial acts
- PVID remote verification: Biometric systems enable distance notarisation through facial recognition, liveness detection, and document authentication
- Security vs fraud: Enhanced verification measures combining AI detection, behavioural analysis, and professional judgement counter evolving fraud threats
Understanding Digital Identity in Notarial Context
What Is Digital Identity for Notary Services?
Digital identity represents the collection of electronic attributes that uniquely identify an individual in the digital realm. Within notary services, digital identity serves as the foundation for verifying that the person signing a document is genuinely who they claim to be.
According to the European Commission's eIDAS regulation, digital identity comprises two essential components:
- Identification elements: Name, date of birth, address, biometric data (facial recognition, fingerprints)
- Location elements: IP address, geographic positioning data, device information
However, it's crucial to understand that digital identity in notarial services isn't a single concept but rather a complex ecosystem of interconnected processes.
Five Critical Distinctions You Must Understand
Many professionals incorrectly use terms like "identity," "authentication," and "signature" interchangeably. These are distinct concepts with specific legal meanings:
Concept | Definition | Legal Framework | Notarial Application |
|---|---|---|---|
Digital Identity | Digital representation of a person via their attributes | eIDAS, UK GDPR | Establishes who the signatory is |
Identification | Process of verifying someone is who they claim to be | PVID Framework (substantive/high level) | Creates new proof of identity |
Authentication | Verification of a previously established identity | eIDAS Article 8 | Confirms identity for subsequent transactions |
Electronic Signature | Technical process linking a signatory to a document | eIDAS Regulation 910/2014 + UK law | Secures the commitment |
Authentic Electronic Act | Notarised act created on electronic medium | UK statutory instruments | Creates enforceable legal document |
Warning
Identification creates a new identity proof, whilst authentication verifies an existing one. For notarial services, proper identification must occur before any electronic signature can have legal validity. Failing to distinguish these concepts can invalidate your documents and expose your business to legal risks.
The Three Levels of Electronic Signatures
Not all electronic signatures offer the same legal guarantees. The eIDAS regulation establishes three distinct levels, each requiring progressively stricter digital identity verification:
1. Simple Electronic Signature (SES)
- Weak identity presumption
- Suitable for low-risk transactions
- Minimal verification requirements
2. Advanced Electronic Signature (AES)
- Uniquely linked to the signatory
- Under exclusive signatory control
- Capable of detecting subsequent changes
3. Qualified Electronic Signature (QES)
- Based on a qualified certificate
- Created by a qualified signature creation device
- Legal equivalent of handwritten signature (Article 25 eIDAS)
Important
For authentic notarial acts, only qualified electronic signatures are legally admissible. This requirement necessitates robust digital identity verification systems complying with eIDAS "high" or "substantive" assurance levels.
At Yousign, our qualified electronic signature solution ensures full compliance with UK eIDAS requirements, providing notaries and legal professionals with the highest level of identity assurance.

The UK and European Regulatory Framework
eIDAS Regulation: The Foundation
The eIDAS Regulation (EU) No 910/2014 creates a standardised framework for electronic identification and trust services across Europe, directly impacting how notaries handle digital identity.
Three levels of identity assurance (Article 8):
- Low: Minimal verification, limited legal value
- Substantive: Thorough verification, very low error probability
- High: Maximum protection against identity falsification, mandatory for qualified signatures
Mutual recognition principle (Article 6): Member states must recognise electronic identification schemes from other EU countries, but only at substantive and high levels. However, eID scheme notification remains incomplete across the EU, with implementation progressing at varying speeds among member states.
eIDAS 2.0: What's Changing for Notaries
The revised eIDAS Regulation (EU) 2024/1183, which entered into force on 20 May 2024, introduces significant changes affecting notarial practice:
European Digital Identity Wallet (EUDI Wallet)
- Mandatory deployment by all member states by December 2026
- Provides "high" level assurance automatically
- Enables storage of identity credentials, professional qualifications, and digital signatures
- Creates interoperability across EU borders
New Qualified Trust Services:
- QEAA (Qualified Electronic Attestation of Attributes): Certifies professional status (solicitor, notary public)
- Qualified electronic archiving: Long-term document preservation
- Remote qualified signature management: Enables cloud-based signature creation devices
Good to know
The EUDI Wallet will revolutionise notary services by enabling instant identity verification across all EU member states. UK businesses operating in Europe should prepare for integration by late 2026.
UK Implementation and GOV.UK Digital Identity
Whilst the UK has left the EU, it maintains alignment with eIDAS principles through domestic legislation. The UK government's approach includes:
- Unified identity and authentication system
- Multi-level verification (medium and high confidence)
- Biometric verification via facial recognition
- Currently used for numerous UK government services, with ongoing expansion
Limitations for notarial services:
- Not yet recognised as Article 24 eID method
- No qualified certificate issuance capability
- Limited acceptance by UK notaries as of March 2026
The UK must develop its own qualified electronic identity scheme to fully support remote notarisation with the same legal certainty as traditional face-to-face verification.
Digital Identity Verification Process for Notaries
PVID: Remote Identity Verification Providers
PVID (Prestataire de Vérification d'Identité à Distance) systems represent the technical solution enabling notaries to verify client identity remotely whilst maintaining security standards equivalent to physical presence.
The PVID verification process typically includes:
- Document capture: Client photographs their official identity document (passport, driving licence)
- Document authentication: OCR analysis, hologram detection, NFC chip reading
- Biometric verification: Facial recognition matching document photo to live selfie
- Liveness detection: AI-powered checks to prevent deepfake and photo-spoofing attacks
- Identity matching: Cross-referencing against official databases
- Certificate issuance: Digital certificate valid for subsequent authentications
Certified PVID providers in Europe (substantive level assurance):
- Docaposte (AR24)
- IDnow
- Netheos/Namirial
- Ubble (NJF Vision)

Security Challenges and Fraud Prevention
The Rising Threat of Digital Identity Fraud
Remote notarisation faces unprecedented security challenges as fraudsters develop increasingly sophisticated attack methods:
Alarming statistics:
- Deepfake fraud techniques have evolved dramatically, with sophisticated attacks targeting financial and legal sectors
- £1.2 billion lost to fraud in UK (2023, UK Finance), with authorised push payment fraud accounting for £459.7 million
- Fraud affects over 444,000 victims annually in the UK, with identity fraud representing a significant proportion (Cifas 2025 data)
- Significant increases in falsified digital documents continue to challenge remote notarisation systems
Deepfakes: A Serious Emerging Threat
Deepfake technology uses artificial intelligence to create convincing fake videos of real people, potentially fooling basic identity verification systems. Notaries must be particularly vigilant as deepfakes can:
- Bypass facial recognition systems
- Simulate liveness detection checks
- Create false video conferences
- Generate fraudulent identity documents
How Notaries Protect Against Digital Identity Fraud
Modern PVID systems employ multiple security layers:
Technical safeguards:
- 3D liveness detection: Requires head movement and facial expressions that deepfakes cannot easily replicate
- Multi-angle biometric capture: Analyses facial geometry from various perspectives
- NFC chip verification: Reads encrypted data from biometric passports
- Hologram and watermark analysis: Detects sophisticated document forgeries
- Behavioural analysis: Monitors interaction patterns for anomalies
Procedural safeguards:
- Mandatory video recording of verification sessions
- Secure archiving with qualified timestamping
- Cross-referencing against anti-money laundering databases
- Professional liability insurance covering identity fraud
Warning
Whilst PVID technology offers robust protection, many notaries express concerns about whether current systems adequately detect the most advanced deepfakes. Always combine technical verification with professional judgement, especially for high-value transactions.
Practical Applications in Notarial Services
When Digital Identity Verification Occurs
Digital identity plays a crucial role at multiple stages of notarial service delivery:
1. Client onboarding
- Initial identity verification (physical or remote via PVID)
- Collection of anti-money laundering documentation
- Establishment of digital credentials for future transactions
2. Document preparation
- Accessing secure client portals
- Querying official registries (wills, beneficial ownership)
- Document collaboration platforms
3. Signature ceremony
- Re-authentication of parties before signing
- Creation of qualified electronic signatures
- Notary applies their own qualified signature
4. Archiving and retrieval
- Long-term storage of notarial acts (75-100 years)
- Identity verification for parties requesting certified copies
- Maintaining audit trails of all verification steps
Checklist: Preparing for Remote Digital Identity Verification
Confirm document eligibility
Verify your document type permits remote notarisation under UK law
Prepare valid ID
Ensure passport or biometric driving licence is current, undamaged, and clearly readable
Check technical requirements
Stable internet connection (minimum 5 Mbps), functioning webcam, well-lit environment without backlighting
Gather supporting documents
Proof of address (utility bill, bank statement), beneficial ownership information if required for corporate matters
Review costs and timeframes
Understand PVID + notarisation fees, expected processing time, and certificate validity period before booking
Test your equipment
Complete a test call if offered by your provider to ensure audio/video quality is sufficient
Clear your schedule
Allow 45-60 minutes uninterrupted time in a quiet, private location
Documents Requiring Qualified Identity Verification
Not all notarial services permit remote procedures. Some require physical presence regardless of digital identity capabilities:
Mandatory physical presence:
- Marriage contracts
- Authentic wills
- Renunciation of inheritance rights (solemn acts)
Permitted remote notarisation with qualified digital identity:
- Powers of attorney
- Property sale agreements (in some jurisdictions)
- Corporate documents and board resolutions
- Statutory declarations
- Affidavits and sworn statements
- Apostille certificates (where local authority accepts remotely notarised documents)
Always verify current UK requirements, as legislation continues evolving. The UK Government's guidance on electronic signatures provides essential compliance information.
Cross-Border Recognition Challenges
One significant limitation of current digital identity systems is inconsistent cross-border recognition. A qualified electronic signature created in one EU member state should be automatically recognised in others, but practical obstacles include:
- Different technical standards
- Varying verification procedures
- Language barriers in certificate interpretation
- Incomplete implementation of mutual recognition frameworks
Good to know
The EUDI Wallet aims to resolve these inconsistencies by creating a unified European digital identity infrastructure. UK businesses engaging in cross-border transactions should monitor developments closely and prepare for integration requirements.
Compliance Requirements for Notaries
Anti-Money Laundering Obligations
Notaries are obligated entities under UK anti-money laundering legislation, requiring rigorous digital identity verification:
Mandatory procedures:
- Verify client identity before providing services
- Identify beneficial owners (25%+ ownership threshold)
- Conduct risk-based due diligence (graduated approach)
- Report suspicious activities to the National Crime Agency
- Retain verification records for 5 years
Digital identity systems must capture and preserve evidence sufficient to satisfy these regulatory requirements, including:
- Original identity documents
- Verification methodology used
- Date and time of verification
- Name of verifying professional
UK GDPR and Biometric Data
Identity verification necessarily involves processing personal data, often including biometric data classified as "special category" under UK GDPR (Article 9).
Legal requirements:
- Conduct Data Protection Impact Assessment (DPIA) before implementing biometric verification
- Obtain explicit consent or establish alternative lawful basis
- Implement appropriate technical and organisational safeguards
- Limit data retention to necessary periods
- Provide transparent privacy information
Retention periods for notaries:
- Notarial acts: 75-100 years
- AML verification records: 5 years
- Biometric verification data: varies by provider and legal basis
Important
The Information Commissioner's Office (ICO) continues to enforce UK GDPR rigorously. Ensure your digital identity processes comply fully with data protection requirements.
The Future of Digital Identity in Notarial Services
EUDI Wallet Integration
By December 2026, all EU member states must offer at least one European Digital Identity Wallet. For notaries, this creates unprecedented opportunities:
Expected capabilities:
- Instant identity verification across all EU countries
- Portable professional qualifications (QEAA)
- Seamless cross-border notarisation
- Reduced verification costs and processing times
- Enhanced security through standardised protocols
UK notaries serving European clients will need to integrate EUDI Wallet compatibility or risk competitive disadvantage.
Blockchain and Distributed Ledger Technology
Whilst still experimental, some notarial organisations are exploring blockchain technology for:
- Immutable identity verification records
- Decentralised certificate management
- Timestamping and document integrity verification
- Smart contract integration for automated compliance
Current adoption remains marginal, with limited institutional integration. However, as technology matures, blockchain may offer additional layers of security and transparency for digital identity in notarial services.
Artificial Intelligence in Identity Verification
AI systems are being deployed both by fraudsters (creating deepfakes) and by identity verification providers (detecting them). Future developments include:
- Real-time deepfake detection
- Behavioural biometrics analysis
- Predictive fraud risk assessment
- Automated compliance checking
Notaries must stay informed about these technological developments to maintain effective protection against evolving threats whilst leveraging AI's benefits for efficiency and accuracy.
Frequently Asked Questions
What is the difference between identification and authentication in notary services?
Identification is the initial process of verifying someone's identity and creating a new proof (such as a digital certificate). Authentication verifies a previously established identity for subsequent transactions. For notarial services, proper identification must occur first, followed by authentication whenever that person conducts additional transactions. This distinction is crucial for compliance with eIDAS requirements and anti-money laundering regulations.
Can all notarial documents be signed remotely using digital identity?
No. Certain solemn acts require physical presence regardless of digital identity capabilities, including marriage contracts, authentic wills, and renunciation of inheritance rights. However, many common notarial services—including powers of attorney, property agreements, and corporate documents—can be handled remotely with qualified digital identity verification and electronic signatures meeting eIDAS standards.
How secure is remote identity verification compared to face-to-face verification?
Modern PVID systems employing biometric verification, liveness detection, and document authentication can achieve security levels comparable to face-to-face verification. However, the sophistication of deepfake technology means notaries must use certified providers and apply professional judgement, especially for high-value or high-risk transactions. Multi-factor authentication and ongoing technological improvements add additional security layers.
Is GOV.UK One Login sufficient for notarial services?
Not currently. As of March 2026, GOV.UK One Login is not recognised as an Article 24 eID method under eIDAS and cannot issue qualified certificates. Notaries must use certified PVID providers and qualified trust service providers (QTSPs) to create documents with full legal validity. This may change as UK digital identity infrastructure evolves.
What happens if digital identity verification fails?
If remote verification fails (due to poor document quality, lighting issues, or system inability to confirm identity), parties must either retry with improved conditions or revert to traditional face-to-face verification. Some transactions may require physical presence as a fallback option. Most PVID providers offer technical support to resolve common issues before abandoning remote verification.
Can I get an apostille certificate through digital identity verification?
Yes, in many cases. An apostille certifies that a document is authentic for use in countries party to the Hague Convention. Whilst the notarisation itself can be completed remotely using qualified digital identity verification, the apostille issuance process depends on your jurisdiction. In the UK, the Foreign, Commonwealth & Development Office (FCDO) handles apostille requests, and some services now accept digitally notarised documents. However, you may still need to submit physical copies for the apostille stamp. Check with your notary whether your remotely notarised document qualifies for apostille processing.
How long is my digital certificate valid after remote identity verification?
Digital certificate validity varies by provider and verification type. Some PVID providers offer reusable certificates valid for extended periods (commonly up to 3 years), during which you can authenticate yourself for multiple notarial services without repeating the full PVID process. This reusability makes remote notarisation particularly cost-effective for individuals or businesses requiring regular notarial services. Always confirm certificate validity periods and renewal requirements with your chosen provider.
Conclusion: Embracing Digital Identity in Notarial Practice
Digital identity has evolved from an experimental concept to an essential component of modern notarial services. As remote notarisation becomes increasingly common and cross-border transactions grow more complex, understanding and implementing robust digital identity verification is no longer optional—it's a professional necessity.
The regulatory landscape continues evolving rapidly, with the eIDAS 2.0 regulation and the EUDI Wallet creating both opportunities and compliance obligations. Notaries must stay informed about these developments, invest in certified verification systems, and maintain vigilance against emerging fraud threats including deepfakes and sophisticated identity fraud.
At the same time, digital identity offers remarkable benefits: reduced transaction times, enhanced accessibility for clients, improved security through layered authentication, and seamless cross-border service delivery.
