AML Compliance and Electronic Signature in Finance: 2026 Guide

AML (Anti-Money Laundering) compliance and electronic signature are now two inseparable pillars for financial institutions, payment platforms and fintechs operating in Europe. Since the entry into force of the 6th anti-money laundering directive (6AMLD) and the progress of the EU's AML 2024-2025 regulatory package — including the creation of the European Money Laundering Authority (AMLA) — obligated entities must demonstrate an unprecedented level of due diligence. Electronic signature, when deployed correctly, is not simply a dematerialisation tool: it becomes a compliance instrument in its own right. This article guides you through the AML obligations applicable to electronic signature, the required assurance levels, available technical solutions and best practices to adopt for 2026.

Why electronic signature is at the heart of AML compliance

The fight against money laundering rests on three fundamental pillars: customer knowledge (KYC — Know Your Customer), transaction monitoring and evidence retention. Electronic signature intervenes directly in the first two and third aspects.

Electronic signature as verified identity proof

In the AML framework, the establishment of a business relationship is the most exposed moment. Article 13 of Directive 2015/849/EU (4AMLD, as amended by 5AMLD) imposes rigorous verification of customer identity before any contractual relationship is established. Advanced or qualified electronic signature — within the meaning of eIDAS Regulation No. 910/2014 — guarantees that the signatory is indeed the person they claim to be, through a documented authentication and identification process. A qualified electronic signature (QES), issued by a qualified trust service provider (QTSP) listed on the European Trust List, offers the "high" assurance level as defined by eIDAS 2.0 Regulation (EU Regulation 2024/1183 which entered into force in May 2024). This level is compatible with the enhanced due diligence requirements imposed for high-risk customers.

Traceability and audit trail compliant with AML requirements

AML regulations require the retention of KYC documents for a minimum period of 5 years after the end of the business relationship (Article 40 of Directive 2015/849). Electronic signature natively generates a complete audit trail: certified time-stamping, document hash, signatory identity, access logs and cryptographic certificates. This traceability ensured by electronic time-stamping directly meets the retention and proof requirements imposed by supervisory authorities — ACPR in France, BaFin in Germany, FCA in the United Kingdom.

Integration into digital onboarding processes

Fintechs and neobanks have massively digitalised their onboarding. According to the McKinsey Digital Banking 2025 report, over 78% of new European bank accounts are opened entirely online. In this context, electronic signature integrated into a KYC onboarding journey makes it possible to:

• Collect informed customer consent on terms and conditions and data processing policy (GDPR)
• Formalise authorisation for collection of identity documents and proof of residence
• Finalise account opening contracts with maximum evidentiary value
• Archive the entire file in an auditable digital safe

For obligated entities seeking to strengthen their system, the comprehensive guide to electronic signature in business constitutes a structuring starting point.

The signature levels required according to AML risk profile

One of the most frequent questions from compliance teams concerns the level of electronic signature to deploy according to the customer's risk level. The risk-based approach, at the heart of the AML system, also applies to technology choice.

Simple and advanced electronic signature: standard risk use cases

For customers identified as presenting a standard risk — natural persons residing in an EU Member State, without particular risk factors — an advanced electronic signature (AES) is generally sufficient. AES is based on signature creation data linked to the signatory in a unique way, it is created from data that only the signatory can use under their exclusive control, and it allows detection of any subsequent modification of the signed document (Article 26 of eIDAS Regulation). Compliant eIDAS solutions such as Certyneo make it possible to deploy this level of signature with real-time identity verification through document recognition (OCR + biometric liveness check), which satisfies standard due diligence requirements.

Qualified signature: obligation for enhanced due diligence

When the customer's risk profile is high — politically exposed persons (PEPs), nationals of third countries with high risk listed by the European Commission, significant-value transactions — enhanced due diligence (EDD) is required. In this context, only a qualified electronic signature guarantees the required assurance level. QES involves the use of a qualified signature creation device (QSCD) and a qualified certificate issued by an accredited QTSP. To better understand the differences between these levels and choose the right solution, the comparison of electronic signature solutions available on Certyneo provides a structured analysis of market offerings in 2026.

The role of remote identity verification (eIDAS 2.0 and EUDI wallet)

eIDAS 2.0 Regulation (EU 2024/1183) introduces the European digital identity wallet (EUDI Wallet), whose deployment is planned by the end of 2026 in all Member States. This wallet will allow citizens to present verified identity attributes (nationality, date of birth, address) in a decentralised manner, without having to resubmit their documents to each service provider. For AML compliance, this development is major: it will allow certified identity verification at the "high" level directly during the signing process, without additional friction for the user. Financial institutions that integrate eIDAS 2.0-compatible solutions today are anticipating this transition and reducing their regulatory risk in the medium term. The update on eIDAS 2.0 Regulation published by Certyneo details the concrete implications for obligated entities.

Specific obligations for financial actors in the matter of AML signature

The obligated entities concerned

Directive 2015/849/EU, transposed into French law in Articles L. 561-1 et seq. of the Monetary and Financial Code, defines a broad scope of entities subject to AML regulations: credit institutions, payment institutions, life insurance companies, wealth management advisers, real estate agents conducting transactions exceeding €10,000, legal professions, and since 2020, providers of services on digital assets (PSAD) now subject to CASP authorisation under the MiCA regime. For each of these categories, the documentation of contractual relationships through traceable electronic signature is an implicit requirement stemming from retention and evidence obligations.

Data retention: GDPR and AML articulation

An apparent tension exists between the retention period imposed by AML (5 years minimum) and the data minimisation principle of GDPR (Regulation EU 2016/679). The EDPB (European Data Protection Board) clarified in its Guidelines 4/2022 that the legal basis for retention for fraud and money laundering prevention purposes constitutes a justified derogation from the right to erasure, provided that the retained data are strictly necessary. Electronic signature, by archiving only strictly necessary cryptographic metadata and identity evidence, makes it possible to satisfy both regimes simultaneously. The use of a certified digital safe, separate from the current document management system, is the best practice recommended by FATF (Financial Action Task Force) in its guidelines on digital transformation of 2023.

Sanctions and risks in case of non-compliance

Sanctions for AML violations are significant. In France, the ACPR (Autorité de Contrôle Prudentiel et de Résolution — Prudential Supervisory Authority and Resolution) can impose financial sanctions of up to €100 million or 10% of annual turnover. In 2025, the ACPR imposed sanctions totalling more than €47 million against financial actors, several cases of which involved failures in documenting and verifying relationship establishment. The absence of a reliable audit trail — which electronic signature precisely makes it possible to establish — was among the grievances retained in several public decisions.

Best practices for deploying AML-compliant electronic signature

Integrate signature into the KYC workflow from the outset

The "privacy by design" approach imposed by GDPR meets here the "compliance by design" approach recommended by FATF. This means that electronic signature must not be added as a superficial layer to an existing process, but integrated from the outset of customer journey design. Flows must be designed so that each stage automatically generates the necessary evidence: signature certificate, audit report, qualified time-stamp, document hash. Compliance teams must work together with IT teams to define clear orchestration rules: which signature level for which document type, what retention period, what metadata to retain.

Choose an accredited and auditable QTSP service provider

The choice of electronic signature service provider is structuring for AML compliance. It is necessary to verify that the service provider is listed on the national trust list (in France, managed by ANSSI) and on the European Trust List, that it is certified according to ETSI EN 319 411 standards (for certificate policies) and ETSI EN 319 132 (for XAdES signatures), and that it has an annual audit report conducted by an accredited body. The ability to export evidence in a standardised format (PAdES, XAdES, CAdES) is also essential to enable their use in judicial proceedings or AML investigations. Institutions seeking to optimise their system can use the Certyneo ROI calculator to quantify the compliance and operational efficiency gains associated with electronic signature.

Train teams and document procedures

AML compliance does not end with technology. Front-office teams, compliance officers and risk managers must be trained in the specifics of electronic signature in an AML context: understanding signature levels, knowing how to interpret an audit report, knowing the procedures to follow in case of dispute. Internal documentation of signature procedures — integrated into compliance manuals — is examined during ACPR inspections. Clear, tested and regularly updated procedures demonstrate the institution's commitment to a proactive compliance approach.

Legal framework applicable to AML compliance and electronic signature

The articulation between electronic signature and anti-money laundering rests on a dense regulatory corpus, both European and national.

eIDAS Regulation No. 910/2014 and eIDAS 2.0 (EU 2024/1183): These texts define the three levels of electronic signature (simple, advanced, qualified) and the conditions for mutual legal recognition between Member States. Article 25 of eIDAS Regulation lays down the principle of non-discrimination: an electronic signature cannot be refused as evidence in court solely on the ground that it is in electronic form. eIDAS 2.0 Regulation, which entered into force in May 2024, strengthens digital identity requirements with the introduction of the EUDI Wallet.

Civil Code, Articles 1366 and 1367: Article 1366 of the French Civil Code recognises electronic writing as equivalent to writing on paper provided that the person from whom it emanates can be duly identified and it is established in conditions of a nature to guarantee its integrity. Article 1367 specifically governs electronic signature under French law, referring to conditions laid down by decree in Council of State (Decree No. 2017-1416 of 28 September 2017).

AML Directives — 4AMLD (2015/849/EU), 5AMLD (2018/843/EU), 6AMLD (2018/1673/EU): These directives impose on obligated entities obligations to verify identity, retain documents for 5 years, monitor transactions and report suspicions to the competent financial intelligence unit (TRACFIN in France). The French transposition is found in Articles L. 561-1 to L. 565-1 of the Monetary and Financial Code.

EU AML 2024 Package: EU Regulation 2024/1624 (AMLR), directly applicable in all Member States from 2027, and Directive EU 2024/1640 (AMLD6) harmonise due diligence rules and create the European Money Laundering Authority (AMLA), headquartered in Frankfurt. These texts strengthen the requirements for identity verification by electronic means, making eIDAS compliance even more strategic.

GDPR No. 2016/679: Article 5 (data minimisation), Article 17 (right to erasure, with its legal exceptions) and Article 30 (records of processing activities) apply fully to processing related to electronic signature in an AML context. The legal basis for retention for purposes of legal obligation (Article 6.1.c of GDPR) justifies prolonged retention of signature data.

ETSI Standards: ETSI EN 319 132-1 defines XAdES electronic signature profiles. ETSI EN 319 102-1 specifies signature creation and validation procedures. These technical standards are the operational translation of eIDAS legal requirements for technical service providers.

Non-compliance risks: Beyond ACPR financial sanctions (up to €100 M or 10% of turnover), AMLR 2024 provides for harmonised sanctions at EU level that may reach 10% of consolidated worldwide turnover for the most serious violations. Directors may also be personally held accountable, with prohibitions on practising provided for in Article 42 of AMLD6 Directive.

Usage scenarios: electronic signature and AML compliance in practice

Scenario 1 — Digital onboarding in an authorised payment institution

An authorised payment institution, authorised by the Banque de France, handling approximately 15,000 new relationship establishment per month via its mobile application, faces strict AML requirements for customer identity verification. Before implementing an advanced electronic signature solution integrated into its onboarding journey, the institution relied on manual document verification processes, generating average delays of 72 hours and an abandonment rate of 34% during subscription.

By deploying an advanced electronic signature solution combined with biometric identity verification (liveness check + identity document OCR), the institution reduced onboarding time to less than 8 minutes for 89% of standard cases. The audit trail automatically generated — including the signature certificate, biometric verification report and qualified time-stamp — directly meets AML retention requirements. The abandonment rate dropped from 34% to 11%, representing a net increase in completed subscriptions of around 35%, according to ranges observed in Juniper Research 2025 reports on digital banking.

Scenario 2 — Managing enhanced due diligence in a portfolio management company

A portfolio management company managing assets for wealthy clients (UHNWI — Ultra High Net Worth Individuals) is subject to enhanced due diligence obligations for all its clients, a significant fraction of its clients being classified as PEPs (Politically Exposed Persons). Contractual documentation — management mandates, risk acceptance letters, periodic signed reporting — represents several thousand documents per year.

By deploying a qualified electronic signature solution for all PEP documents and integrating automatic archiving in a certified digital safe NF461, the company has established a complete and auditable audit trail. During an ACPR inspection lasting 48 hours, all requested files were able to be produced in less than 2 hours, compared to a sector average estimated at 2-3 days according to feedback published by ACPR in its 2024 annual inspection report. Compliance teams also reduced by 60% the time spent preparing inspection files.

Scenario 3 — AML compliance for a provider of services on digital assets (CASP)

A provider of services on digital assets (CASP) subject to MiCA Regulation and enhanced AML obligations applicable since January 2026 must document all contractual relationships with identity verification requirements equivalent to those of a credit institution. Platform usage contracts, custody mandates and investment policy certificates must be signed and retained.

By integrating an advanced electronic signature solution via API into its registration journey, the CASP was able to automate the generation and signature of contractual documents upon KYC validation. Each signed document is automatically indexed in the compliance management system with its cryptographic metadata. This approach reduced manual compliance team interventions on standard cases by 80%, freeing up time for processing high-risk cases requiring human review.

Conclusion

AML compliance and electronic signature now form an inseparable partnership for any financial actor operating in Europe in 2026. The successive anti-money laundering directives, culminating in the 2024 AML package and the creation of AMLA, have significantly raised the level of requirement for identity verification, document traceability and evidence retention. Electronic signature — provided it is deployed at the right level (advanced or qualified according to risk profile), integrated from the outset of customer journey design and supported by an accredited QTSP service provider — structurally meets these requirements. It constitutes both a compliance tool, a lever for operational efficiency and a competitive advantage in the digital customer relationship.
