Art. 1. Customer due diligence  
(…)1  
(3) (…)2 “For the purposes of Article 3(7) of the Law of 12 November 2004 on the fight  
against money laundering and terrorist financing, as amended (hereinafter the “Law”), special”3  
attention shall notably be paid to: significant transactions relative to a business relationship,  
transactions that exceed certain limits, very high account turnover inconsistent with the size of  
the balance, or transactions which fall out of the regular pattern of the account's activity.  
Professionals shall scrutinise, as far as possible, the background and purpose of such  
transactions, set forth their findings in writing and keep these documents in accordance with  
Article 3(6)(b) of the Law and to keep them available for the “Luxembourg” authorities  
“responsible for the fight against money laundering and terrorist financing”4 and auditors for at  
least five years, without prejudice to longer record-keeping periods prescribed by other laws.  
“(4) In order to apply due diligence measures to customers, "appropriate times on a  
risk-sensitive basis" within the meaning of Article 3(5) of the Law shall notably mean one of the  
following situations:  
a transaction of significance takes place;  
customer documentation standards change substantially;

as regards banking business, a material change in the way that a customer's account  
is operated;  
the professional becomes aware that it lacks sufficient information about an existing  
customer.  
The professionals shall be able to prove to the supervisory authorities or self-regulatory  
bodies that the extent and frequency of customer due diligence measures is appropriate in view  
of the money laundering and terrorist financing risks.  
The customer due diligence measures shall be carried out at least every seven years,  
without prejudice to higher frequency depending on the risk assessment.”5  
(5) The record-keeping obligation of documents “, data”6 and information as provided  
in Article 3(6) of the Law shall include the obligation to maintain records of the identification  
data, account files and of the business correspondence “, as well as the results of any analysis  
carried out”7, for at least five years following the termination of an account or business  
relationship, without prejudice to any longer record-keeping periods prescribed by other laws.  
If a “supervisory”8 authority requests, in specific cases and for the fulfilment of its mandate, to  
apply a longer record-keeping period than the minimum period provided above, the professional  
shall comply with this request.  
Transaction records shall be sufficient to allow reconstruction of various transactions so  
as to provide, if necessary, evidence for prosecution of criminal activity.  
Together, the different components of an “individual”9 transaction record shall thus  
provide, in particular, the following information: name of the customer and beneficiary “of the  
transaction”10, address or other identifying information“()”11, the nature and date of the  
transaction, the type and amount of currency involved, and the type and identifying number of  
any account involved in the transaction.  
Professionals shall ensure that all the above-mentioned transaction records and  
information are available to the “Luxembourg”12 authorities “responsible for the fight against  
money laundering and terrorist financing”13, when acting in the context of their mandate, so  
that professionals may respond “without delay”14 to information requests by such authorities.  
(6) Both customer due diligence in general and the assessment of the extent of the  
measures to be applied on a risk-sensitive basis in particular, shall be consistent with the  
guidelines issued by the “supervisory”15 authorities “and self-regulatory bodies”16, for instance  
in the form of circulars.

“(7) The threshold of EUR 1,000 as laid down in Article 3(1)(b)(ii) of the Law shall also  
apply to occasional operations carried out by virtual asset service providers as defined in Article  
7-1 of the Law.”  
Art. 2. Simplified customer due diligence  
It is not mandatory to apply the simplified customer due diligence regime as set out in  
Article 3-1 of the Law and is therefore not imposed on professionals.  
The obligation to gather sufficient information in any circumstances so as to establish  
whether the customer meets the necessary conditions for Article 3-1 of the Law to apply, shall  
at least include customer identification and monitoring of the business relationship so that the  
necessary conditions for Article 3-1 of the Law are always met and the verification that there is  
no suspicion of money laundering or terrorist financing. This obligation also applies to the  
situations referred to in Article 3-1(4) of the Law.  
(Grand-ducal Regulation of 5 August 2015)  
“The professionals may reduce the identification measures and need not verify the  
identity of their customer and, where applicable, the beneficial owner of the business  
relationship when they carry out online payment services fulfilling each of the following  
conditions:  
1. the transaction concerns the provision of payment services listed under number  
3, second and third indents, number 4, second and third indent, number 5 and  
number 7 of the Annex to the law of 10 November 2009 on payment services,  
as amended;  
2. the transaction is executed via accounts held with payment service providers  
located in the EU or in a third country which imposes equivalent requirements  
relating to the fight against money laundering and terrorist financing;  
3. the transaction does not exceed a unit amount of EUR 250;  
4. the total amount of the transactions executed for the customer during the 12  
months preceding the transaction does not exceed EUR 2,500.  
The possibility not to verify the identity of the customer and, where applicable,  
of the beneficial owner of the business relationship, also applies to professionals  
with respect to electronic money referred to in Article 3-1(4)(…)17 of the Law.”  
The simplified customer due diligence regime is excluded when there is a suspicion of  
money laundering or terrorist financing, when there are doubts about the veracity or adequacy  
of previously obtained data or in specific circumstances which carry a higher risk.  
Art. 3. Enhanced customer due diligence  
“(1) Business relationships and transactions involving notably high-risk countries  
constitute higher-risk situations within the meaning of Article 3-2(2) of the Law which require  
particular attention and the application of enhanced due diligence measures.”18

“Supervisory authorities”19 and, where applicable, self-regulatory bodies of the different  
professionals shall inform the professionals of concerns about country-specific loopholes in the  
relevant provisions for the fight against money laundering and terrorist financing of the countries  
referred to above.  
Where such a country continues not to apply or insufficiently applies measures for the  
fight against money laundering and terrorist financing, these authorities and bodies shall warn  
the professionals about the risks of money laundering and terrorist financing in transactions with  
natural or legal persons of that country. They may set out “counter-measures”20 based on a  
case-by-case approach which professionals must implement in view of the risk identified.  
“The authorisation procedure requiring the approval of senior management shall also  
include the anti-money laundering and counter-terrorist financing compliance officer.”21  
(2) For non-face-to-face transactions “and where the professional has not put in place  
electronic identification means, relevant trust services within the meaning of Regulation (EU)  
No 910/2014 or any other secure, electronic or remote identification process which is regulated,  
recognised, approved or accepted by the relevant national authorities”22, the professionals shall  
have policies and procedures in place to address any specific risks associated with such business  
relationships or transactions. These policies and procedures shall apply when establishing  
customer relationships and when conducting ongoing due diligence.  
(…)23  
(3) In relation to cross-border correspondent (…)24 relationships referred to in Article 3-  
2(3) of the Law, credit institutions“, financial institutions and other institutions concerned by  
this provision”25 shall also:  
determine from publicly available information the reputation of the respondent  
institution and the quality of its supervision, including whether the institution  
concerned has been subject to a money laundering or terrorist financing investigation  
or regulatory action;  
assess the respondent institution's controls against money laundering and terrorist  
financing and ascertain that they are adequate and effective;  
“clearly understand and”26 document the respective responsibilities “as regards”27  
the fight against money laundering and terrorist financing of each institution.

Where a correspondent (…)29 relationship involves the maintenance of "payable-  
through" accounts, credit institutions“, financial institutions and other institutions concerned by  
such relationships”30 shall be satisfied that:  
(a) their customer (the respondent (…)31 institution) has performed all the (…)32  
customer due diligence obligations set out in Article 3 of the Law on those of its  
customers that have direct access to the accounts of the correspondent institution;  
and  
(b) the respondent (…)33 institution is able to provide relevant customer identification  
data “and information”34 upon request to the correspondent institution. A  
Luxembourg credit institution is authorised to provide such “data and”35 information  
within the framework of a correspondent (…)36 relationship.  
To the extent that other institutions which are not credit institutions are involved in  
correspondent banking relationships, these rules shall equally apply to these institutions.  
(4) Enhanced customer due diligence for politically exposed persons shall also apply  
when this person carries out a prominent public function in another Member State or in a third  
country or on behalf of the Member State or the third country.  
Professionals shall put in place appropriate risk management systems“, including risk-  
based procedures,”37 to determine whether a potential customer, a customer or the beneficial  
owner is a politically exposed person.  
Where a customer has been accepted and the customer or beneficial owner is  
subsequently found to be, or subsequently becomes a politically exposed person, professionals  
shall obtain approval to continue the business relationship from the senior management.  
The authorisation procedure requiring approval from the senior management shall “also  
involve”38 the “anti-money laundering and counter-terrorist financing compliance officer”39.  
Professionals shall take reasonable measures to establish the source of wealth and the  
source of funds of customers and beneficial owners identified as politically exposed persons.  
Where professionals are in a business relationship with a politically exposed person, they  
shall be required to conduct enhanced ongoing monitoring on that relationship.

establish and maintain internal procedures, policies and controls“, including risk management

Art. 8. Cooperation requirements with the authorities  
(1) The obligation to communicate information referred to in Article 5(1)(b) of the Law  
shall include the communication of existing documents on which this information is based.  
(2) Pursuant to Article 5(1)(a) of the Law, the obligation to report suspicious  
transactions shall apply for each fact which might be an indication of money laundering “, an  
associated predicate offence”49 or terrorist financing due, in particular for reasons relating to  
the person concerned, to his development, to the source of the funds, to the nature, the purpose  
or procedures of the transactions, without the reporting person classifying the underlying  
offence.  
Particularly in the fight against terrorist financing, this reporting obligation shall also  
apply to funds for which there are reasonable grounds to suspect or they are suspected to be  
linked or related to, or to be used for terrorism, terrorist acts or by “a terrorist”50 “or a terrorist  
group”51 or by those who finance terrorism, without limiting this obligation solely to funds of  
persons listed by the United Nations or by the European Union in the context of the fight against  
terrorism.  
(3) An information request relating to the fight against money laundering and terrorist  
financing pursuant to Article 5(1)(b) of the Law or an instruction “not to execute transactions  
pursuant to”52 paragraph 3 of this article does not presuppose a prior information according to  
paragraph (1)(a) of this article but these measures may also be taken by “the Financial  
Intelligence Unit (hereinafter the “FIU”)”53, in the absence of a “prior”54 suspicious transaction  
report (…)55.

“A request for information from the FIU may be transmitted electronically or, where the  
professional is not registered with the FIU, by mail.”
