Anti-money laundering (AML)

What is anti-money laundering (AML)?

Anti-money laundering (AML) refers to the legal, regulatory, and organisational framework designed to prevent, detect, and report activities intended to conceal the criminal origin of assets. In practice, AML rules are meant to stop offenders from introducing illicit funds into the financial system, moving them through multiple transactions, and making them appear legitimate. The concept is closely connected with counter-terrorist financing (CTF), sanctions compliance, customer due diligence, and internal risk management.

From a legal and operational perspective, AML is not limited to banks. The relevant duties may apply to a wide group of obliged entities, including financial institutions, payment service providers, investment firms, insurers, virtual asset service providers, and, in defined circumstances, also lawyers, notaries, accountants, tax advisers, and businesses involved in high-value transactions. The exact scope of obligations depends on the applicable jurisdiction, the type of service provided, and the risk profile of a given activity. Within the European Union, the AML framework is shaped mainly by successive AML Directives and related regulations, while in Poland key obligations are set out in the Act of 1 March 2018 on Counteracting Money Laundering and Terrorist Financing, as amended.

AML should also be understood as a compliance function. It requires organisations to identify and assess risk, verify clients and beneficial owners, monitor transactions, recognise unusual patterns, keep records, and report suspicious activity to the competent authority. In Poland, this authority is the General Inspector of Financial Information. At group level, AML may also require the adoption of internal procedures, staff training, whistleblowing channels, and controls tailored to the scale and complexity of the business.

What does AML involve in practice?

AML compliance usually begins with a risk-based approach. This means that an organisation should assess the likelihood that its products, services, clients, distribution channels, or geographic exposure could be used for money laundering or terrorist financing. The risk assessment influences the intensity of controls. Lower-risk relationships may justify standard due diligence, while higher-risk cases may require enhanced due diligence, additional verification steps, closer transaction monitoring, and management approval.

One of the core AML obligations is customer due diligence (CDD). This typically includes identifying the client, verifying identity based on reliable documents or data, determining whether the client acts on its own behalf, identifying the beneficial owner, and understanding the purpose and intended nature of the business relationship. For corporate clients, this often involves reviewing registration documents, ownership structures, representation rules, and the background of controlling persons. Where the circumstances justify it, firms may also need to establish the source of funds or source of wealth.

Transaction monitoring is another key area. AML systems are designed to detect red flags such as unusual transfers, complex or economically unjustified structures, inconsistent payment flows, rapid movement of funds between accounts, links with high-risk jurisdictions, or patterns that do not match the declared business profile of the client. If the circumstances raise suspicion, the obliged entity may need to file a suspicious activity report or take other statutory measures. In some cases, the law may also require the application of restrictive measures before a transaction is completed.

AML also covers internal governance. Businesses subject to AML rules often need written procedures, documented risk assessments, a designated person responsible for compliance, training for employees, and mechanisms for handling internal alerts. Failures in this area may lead to regulatory sanctions, reputational harm, civil consequences, and, in serious cases, criminal liability for responsible individuals.

When is AML support worth considering?

Professional AML support is often necessary when a business is entering a regulated market, launching a new financial or payment product, onboarding higher-risk clients, expanding internationally, or facing an inspection by the supervisory authority. It is also relevant during mergers, acquisitions, restructurings, and internal audits, where the quality of AML controls may affect transaction value, liability exposure, and post-closing integration.

For private individuals, AML issues may become relevant when a bank or other institution requests additional documents, blocks a transaction, terminates a business relationship, or questions the origin of funds. This may happen, for example, in connection with property sales, cross-border transfers, cryptocurrency-related activity, inheritance, corporate distributions, or payments involving complex ownership structures. In such situations, legal analysis can help explain the institution’s position, assess whether the measures taken are proportionate, and prepare an appropriate response.

For entrepreneurs, AML advice may be important not only for ongoing compliance, but also for reducing operational and legal risk. A delayed or incorrect implementation of AML procedures can result in reporting failures, onboarding errors, ineffective monitoring, or inadequate documentation. A prompt consultation with a lawyer can help identify gaps at an early stage and reduce the risk of disputes with regulators, contractual disruption, financial loss, or liability for members of management.

In practice, AML matters often overlap with corporate law, tax, criminal law, data protection, internal investigations, and regulatory proceedings. For that reason, effective advice usually requires not only knowledge of AML rules themselves, but also an understanding of how they interact with the wider legal environment of a business.

Law firm support in the field of AML may include in particular:

assessment of whether a business qualifies as an obliged entity under applicable AML regulations,
preparation and review of internal AML procedures and risk assessments,
advice on customer due diligence, beneficial ownership, and enhanced due diligence measures,
support in transaction analysis and identification of AML red flags,
assistance during inspections, regulatory inquiries, and communication with competent authorities,
legal support in cases involving blocked transactions, account restrictions, or reporting obligations,
training for management and staff responsible for AML compliance,
AML due diligence in corporate transactions and business reorganisations.
