The Wolfsberg Group is an association of 13 global banks that aims to develop frameworks and guidance for the management of financial crime risks. The group started as a meeting of banks in 1999 to address anti- money laundering (AML) in private banking, which carries an increased degree of risk from a money laundering perspective. In the course of discussions, they articulated principles that reflected uniformly high standards for this client segment. These principles became the first guidance published by the group under the name Wolfsberg Principles.

one of the key roles of FATF-Style Regional Bodies (FSRBs) is to support the system of mutual evaluation, which is a peer review process that assesses the level of compliance and effectiveness of each member country's anti-money laundering and counter-terrorism financing (AML/CFT) regime12. FSRBs conduct mutual evaluations in accordance with the FATF's methodology and standards, and share the results and recommendations with the FATF and other FSRBs3. Mutual evaluations help identify the strengthsand weaknesses of each country's AML/CFT system, and provide a basis for technical assistance and follow-up actions4.

According to Article 1(3) of Directive (EU) 2015/849 (4th Anti-Money Laundering Directive, 4AMLD),
"knowledge, intent or purpose" required as an element for money laundering may be inferred from objective factual circumstances. This means that the prosecution does not need to prove the actual state of mind of the offender, but can rely on the evidence of the surrounding facts and circumstances that indicate the offender's awareness or intention to launder money. This is consistent with the approach of the Financial Action Task Force (FATF), which defines money laundering as the intentional act of concealing or disguising the origin of criminal proceeds.

According to the Anti-Money Laundering Specialist (the 6th edition) resources, one of the red flags for money laundering in real estate transactions is the use of an appraiser who is not on the approved list of the financial institution. This could indicate a possible collusion between the appraiser and the borrower or the underwriter to inflate the value of the property and obtain a higher loan amount. The anti-money laundering specialist should document the underwriter's actions and the reasons for approving the exception, as well as the discrepancy between the appraised value and the market value of theproperty. The specialist should then file a suspicious transaction report (STR) to the relevant authorities, as required by the local regulations .
