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 progression of the EU's AML regulatory package 2024-2025 — including the creation of the European Union Anti-Money Laundering Authority (AMLA) — subject entities must demonstrate an unprecedented level of due diligence. Electronic signature, when deployed correctly, is not simply a digitisation 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 plays a direct role in the first two and the third pillar.

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 the customer's identity before any establishment of a contractual relationship. Advanced or qualified electronic signature — within the meaning of Regulation eIDAS No. 910/2014 — guarantees that the signatory is indeed the person they claim to be, through a process of documented authentication and identification. A qualified electronic signature (QES), issued by a qualified trust service provider (QTSP) listed on the European trust list, offers the "high" level of assurance as defined by Regulation eIDAS 2.0 (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 clients.

Traceability and audit trail compliant with AML requirements

AML regulations require the retention of KYC documents for a minimum 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, signer identity, access logs and cryptographic certificates. This traceability ensured by electronic time-stamping directly meets the retention and evidence requirements imposed by supervisory authorities — ACPR in France, BaFin in Germany, FCA in the United Kingdom.

Integration into digital onboarding processes

Fintechs and neo-banks have massively digitalised their onboarding. According to the McKinsey Digital Banking 2025 report, more than 78% of new European bank accounts are opened entirely online. In this context, electronic signature integrated into a KYC onboarding journey allows you to:

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

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

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. The AES is based on signature creation data linked to the signatory in a unique manner, 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 Regulation eIDAS). Solutions compliant with eIDAS such as Certyneo allow deployment of 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 at high risk listed by the European Commission, transactions of significant amount — enhanced due diligence (EDD) is required. In this context, only a qualified electronic signature guarantees the required level of assurance. 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 adapted solution, the comparison of electronic signature solutions available on Certyneo offers a structured analysis of market offerings in 2026.

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

Regulation eIDAS 2.0 (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 in the signature process, without additional friction for the user. Financial institutions that integrate eIDAS 2.0 compatible solutions today anticipate this transition and reduce their regulatory risk in the medium term. The update on Regulation eIDAS 2.0 published by Certyneo details the concrete implications for subject entities.

Specific obligations for financial actors in terms of AML signature

The subject 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 undertakings, wealth management advisers, estate agents carrying out transactions exceeding €10,000, legal professionals, and since 2020, providers of services on digital assets (PSADs) now subject to CASP authorisation under the MiCA regime. For each of these categories, documentation of contractual relationships through traceable electronic signature is an implicit requirement arising from conservation 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 principle of data minimisation under 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 prevention and money laundering purposes constitutes a justified derogation to the right to erasure, provided that the retained data are strictly necessary. Electronic signature, by archiving only the cryptographic metadata and identity evidence strictly necessary, allows simultaneous compliance with both regimes. The use of a certified digital safe, separate from the regular document management system, is the best practice recommended by the FATF (Financial Action Task Force) in its guidelines on digital transformation in 2023.

Sanctions and risks in case of non-compliance

Sanctions for AML breaches are significant. In France, the ACPR (Autorité de contrôle prudentiel et de résolution) can impose pecuniary 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, with several cases involving failures in documentation and verification of business relationships. The lack of a reliable audit trail — which electronic signature precisely makes it possible to establish — was among the grievances cited in several public decisions.

Best practices for deploying AML-compliant electronic signature

Integrate signature into the KYC workflow from the design stage

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

Choose an accredited QTSP provider and auditable

The choice of electronic signature provider is structuring for AML compliance. You should verify that the provider is listed on the national trust list (in France, managed by ANSSI) and on the European trust list (EU 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 legal proceedings or AML investigations. Institutions wishing to optimise their system can use Certyneo's ROI calculator to quantify the compliance and operational efficiency gains associated with electronic signature.

Train teams and document procedures

AML compliance does not stop at technology. Front-office teams, compliance officers and risk managers must be trained in the specificities 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 is based on a dense regulatory framework, both European and national.

Regulation eIDAS 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 recognition between Member States. Article 25 of Regulation eIDAS establishes the principle of non-discrimination: an electronic signature cannot be refused as evidence in court solely on the grounds that it is in electronic form. Regulation eIDAS 2.0, 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 it can be duly established from which person it emanates and established under conditions of a nature to guarantee its integrity. Article 1367 specifically governs electronic signature under French law, referring to conditions set by decree in the 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 subject entities obligations for identity verification, retention of documents for 5 years, transaction monitoring and reporting of 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 Package 2024: Regulation EU 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 Union Anti-Money Laundering Authority (AMLA), headquartered in Frankfurt. These texts strengthen requirements for electronic identity verification, 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 Standard EN 319 132-1 defines XAdES electronic signature profiles. ETSI Standard EN 319 102-1 specifies signature creation and validation procedures. These technical standards are the operational translation of the legal requirements of Regulation eIDAS for technical service providers.

Non-compliance risks: Beyond ACPR pecuniary sanctions (up to €100 million or 10% of turnover), Regulation AMLR 2024 provides for harmonised sanctions at EU level that may reach 10% of consolidated worldwide turnover for the most serious breaches. Directors may also be personally pursued, with prohibitions on exercising duties provided for in Article 42 of Directive AMLD6.

Use cases: electronic signature and AML compliance in practice

Scenario 1 — Digital onboarding in an authorised payment institution

An authorised payment institution with the Banque de France, processing around 15,000 new business relationships per month through its mobile application, faces strict AML requirements for customer identity verification. Before implementing an advanced electronic signature solution integrated into its onboarding process, the institution relied on manual document verification processes, generating average delays of 72 hours and a drop-off rate of 34% during subscription.

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

Scenario 2 — Enhanced due diligence management 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 its entire clientele, with a significant fraction of its clients classified as PEPs (Politically Exposed Persons). Contract documentation — management mandates, risk acceptance letters, periodic signed reports — represents several thousand documents per year.

By deploying a qualified electronic signature solution for all PEP documents and integrating automatic archiving in an NF461-certified digital safe, the company created a complete and auditable audit trail. During a 48-hour ACPR inspection, all requested files could be produced in less than 2 hours, compared with an estimated industry average of 2-3 days based on feedback published by the 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 digital asset service provider (CASP)

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

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

Conclusion

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