The clients are not willing to have their names provided to the bank is a red flag that should stop the agent from discussing this potential purchase further, as this could indicate that the clients are trying to evade customer due diligence (CDD) or know your customer (KYC) requirements, or hide their beneficial ownership or source of funds. According to the U.K. Money Laundering Regulations 2017, real estate agents must conduct CDD on their customers and any beneficial owners, and verify their identity and address1. The
U.K. also has a register of people with significant control (PSC) over companies, which requires companies to disclose their beneficial owners2. The use of private companies and wire transfers could also be a sign of layering, a money laundering technique that involves moving funds through multiple accounts or entities to obscure their origin3.

According to the ACAMS CAMS Study Guide, 6th Edition, Chapter 4, Section 4.2, the AML Specialist at a bank should take the following actions upon receiving a confidential alert from law enforcement about suspected money launderers:
Involve the bank's legal and compliance function to address the gravity of the matter and ensure that the bank's response is appropriate and lawful. The legal and compliance function can also advise on the bank's obligations and rights under the relevant laws and regulations, such as the General Data Protection Regulation (GDPR), the Bank Secrecy Act (BSA), and the USA PATRIOT Act.
Perform a search on the bank's client data platform to determine if the bank has had any business with the named individuals or any related parties. The search should include current and past accounts, transactions, wire transfers, and other relevant records. The AML Specialist should also review any existing customer due diligence (CDD) and enhanced due diligence (EDD) information on the potential suspects and update them as necessary.
The other options are not recommended or required actions for the AML Specialist at a bank in this scenario:
Sending out an email to all of the bank's client advisors to request information on any of the individuals could compromise the confidentiality of the alert and expose the bank to legal and reputational risks. It could also alert the suspects or their associates and hinder the law enforcement investigation.
Reporting findings back to law enforcement only if they are of any significance is not sufficient or compliant with the bank's obligations to cooperate with law enforcement and report any suspicious activity. The AML Specialist should report any relevant information or findings to law enforcement as soon as possible, regardless of their significance, and follow the established procedures and protocols for information sharing and reporting.
Responding to law enforcement that their request without a judicial order would breach the bank's GDPR duty with respect to its clients is not accurate or helpful. The GDPR does not prohibit the bank from sharing personal data with law enforcement for the purposes of preventing, detecting, or investigating money laundering or other criminal activities, as long as the bank has a legal basis and safeguards for doing so. The bank should consult with its legal and compliance function to determine the best way to respond to the law enforcement request and balance its GDPR obligations with its anti-money laundering (AML) duties.

International business corporations (IBCs) are entities that are created in jurisdictions that offer low or no taxes, high confidentiality, and minimal regulation. They are often used by individuals and businesses to avoid or evade taxes, conceal assets, and launder money. Some of the risks associated with IBCs are:
They are created in a tax haven. Tax havens are countries or territories that have low or no taxes, lax financial regulation, and high secrecy. They attract IBCs that seek to reduce their tax liabilities, hide their beneficial owners, and evade scrutiny from authorities. Tax havens pose a risk to the global financial system, as they facilitate tax evasion, money laundering, corruption, and illicit financial flows12.
They are established with nominee directors. Nominee directors are individuals who act as the legal representatives of an IBC, but have no actual control or authority over its activities. They are often used to shield the true beneficial owners of the IBC from detection and accountability. Nominee directors pose a risk to the transparency and integrity of the IBC, as they can enable fraud, tax evasion, money laundering, and other criminal activities34.

According to the FATF typology report 2000-20011, lawyers can provide a range of functions that can be useful to a potential money launderer, such as:
Creating complex legal arrangements, such as trusts, foundations, or corporations, that can obscure the identity and ownership of the beneficial owners or the origin and destination of the funds.
Buying and selling property, such as real estate, art, or jewelry, that can be used to transfer or store illicit proceeds or to provide a legitimate cover for the source of funds.
Performing financial transactions on behalf of a client, such as opening bank accounts, transferring funds, issuing checks, or exchanging currencies, that can facilitate the movement or concealment of illicit funds.
Providing legal advice, on the other hand, is not a function that can be directly exploited by a money launderer, unless the advice is related to the above functions or to the avoidance or evasion of anti-money laundering laws and regulations.

According to the Basel Committee on Banking Supervision standards, the following statements best describe sound practices in relation to customer due diligence (CDD) policies and procedures:
Banks should take into consideration the occasional banking transaction or the size/level of assets to build an understanding of the customer's profile and behavior. This is because the nature and frequency of transactions and the size of the account balance may indicate the level of risk associated with the customer and the need for ongoing monitoring1 Banks should develop and implement clear acceptance policies and procedures to identify the types of customer that are likely to pose a higher risk of financing terrorism or money laundering. This is because banks should not enter into or maintain relationships with customers who pose unacceptable risks to the bank or the financial system. Banks should also apply a risk-based approach to CDD and apply more stringent measures to higher-risk customers12 Banks should implement enhanced due diligence measures for entering business relationships with high-risk customers, such as approval by senior management. This is because banks should ensure that they have adequate information and controls to manage the risks posed by such customers and to comply with the relevant laws and regulations. Senior management should be involved in the decision-making process and be accountable for the outcomes12 References: 1: Basel Committee on Banking Supervision, Consolidated KYC Risk Management, October
