Fourthline Terms and Conditions


You are in the process of becoming a client of a financial institution of your choosing (the “Financial Institution”). Before the Financial Institution is permitted to provide financial services to you, it is required by law to verify your identity and perform several checks to comply with the applicable anti-money laundering and counter terrorist financing (“AML”) legislation. We have been engaged to (partially) complete this process on the Financial Institution’s behalf. In this process, we will share your data with a regulated Qualified Trust Service Provider (“QTSP”) if your Financial Institution requires you to sign with a Qualified Electronic Signature (“QES") to complete your onboarding.

In addition, we will provide you with our KYC Vault service (as defined below). This entails that we store the data we obtain from you during the onboarding process in a secure and encrypted digital vault. This enables us and the Financial Institution to remain compliant with AML obligations in the future without having to ask you to go through a new onboarding procedure.

To be able to provide you with onboarding services and our KYC Vault, we need to enter into a legal relationship with you. Upon your acceptance of these terms and conditions (“T&Cs”) an agreement between you and Fourthline is established (the “Agreement”). These T&Cs apply to the abovementioned services we provide to you. Please read this document carefully to be fully aware of all your rights and obligations.


2.1 Fourthline B.V., (“Fourthline”, also referred to as “we” or “us”) is a company incorporated in the Netherlands, which is registered with the Dutch Chamber of Commerce (reg. no. 58905413), and has its registered office at Keizersgracht 452, 1016 GD Amsterdam, the Netherlands. Fourthline is licensed by the Dutch Central Bank (De Nederlandsche Bank) to provide payment services.

2.2 You are advised to print or download and keep a copy of these T&Cs for future reference. We are entitled to revise and update these T&Cs from time to time at our discretion. Fourthline shall publish new versions of the T&Cs on its company website (

3.Onboarding Services 

3.1 Based on an agreement between us and the Financial Institution that you wish to become a client of, we are engaged to provide onboarding services on the Financial Institution’s behalf. You warrant that the information you provide during the onboarding process concerns yourself and is accurate, complete and valid. In case we cannot complete the onboarding process due to the quality or correctness of the information you provide, we will abort the onboarding process and you must restart the process to complete it.

3.2 The onboarding services provided by us are designed to meet applicable AML criteria. After reviewing the data you submitted, we will determine if the onboarding requirements are met. If we successfully complete the onboarding requirements and accept you as our client, this means that we have performed an AML compliant onboarding. In case of a rejection, we will inform you as much as possible and to the extent legally permitted of the reasons for such rejection. We are not liable for any damages you may claim to have incurred as a result of a rejection.

3.3 Upon successful completion of our onboarding services, we will share the relevant data regarding your onboarding with your Financial Institution. Your Financial Institution is ultimately responsible for meeting the client due diligence requirements resulting from applicable AML legislation. As a result, your Financial Institution may always decide, at its discretion to (i) request additional information from you on top of the information we request in our onboarding process, (ii) apply additional conditions to its acceptance of you as its client, or (iii) reject you as its client. We are not responsible for (any delay in) this decision, or liable for any damages you may claim to have incurred as a result of your Financial Institution’s decision in this regard.

3.4 Your Financial Institution may require you to sign a document with a QES as part of its onboarding process. To enable you to sign with a QES, we must obtain a qualified electronic certificate from a licensed QTSP. To that end, we are entitled to share the personal data required to obtain a QES with such QTSP as to enable the QTSP to verify your identity. The QTSP will provide its services in accordance with its own terms and conditions and process your information in accordance with its own privacy statement, both of which will be provided to you prior to us sharing your personal data with any such QTSP.
