Structured onboarding for layered ownership: KYB without the friction

Know Your Business (KYB) checks are a regulatory requirement for financial institutions onboarding corporate clients, not an administrative preference. For businesses with straightforward ownership, the process is typically straightforward. For businesses with layered structures, multiple jurisdictions, or complex shareholdings, it takes more time and more documentation. Understanding why can make the process considerably less frustrating.

What KYB is designed to achieve

KYB is the corporate equivalent of Know Your Customer (KYC). Its purpose is to verify who the business is and, critically, who ultimately controls it. The regulatory obligation sits with the institution carrying out the check. The AML/CTF framework in the UK (governed by the Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017 and the Proceeds of Crime Act 2002) requires regulated firms to identify and verify beneficial owners and to understand the nature and purpose of the business relationship.

Beneficial ownership typically means the individuals who ultimately own or control more than 25% of the entity, or who otherwise exercise significant control. For a privately held company with a simple structure, this is straightforward. For a holding company owned by several trusts, each with their own trustees and settlors, it requires following the ownership chain through each layer.

Why layered structures take longer

Each corporate layer adds verification requirements. A subsidiary owned by a holding company, itself owned by a trust, with a corporate trustee, involves at least three distinct entities whose beneficial owners must be traced. Each entity may require:

• Certificate of incorporation and constitutional documents (articles, shareholder agreement where relevant).
• Register of members or shareholder records.
• Evidence of directors and authorised signatories.
• Identification documentation for directors and beneficial owners: typically passport or national ID plus proof of address.
• For trusts: the trust deed or a summary of its terms, trustee and beneficiary information, and settlor identification.

The institution cannot simply accept a summary from the applicant. Documents must be verifiable, current, and consistent. Where a document is in a language other than English, a certified translation is typically required.

Jurisdictions and enhanced due diligence

Not all jurisdictions are treated the same. Companies incorporated in Financial Action Task Force (FATF)-listed jurisdictions, or jurisdictions the FCA treats as higher-risk, attract enhanced due diligence requirements. This means additional documentation and, in some cases, senior management approval before onboarding can proceed. It does not mean businesses with offshore structures cannot be onboarded; it means the process takes longer and requires more documentation.

Politically exposed persons (PEPs) within the ownership structure, or family members or close associates of PEPs, also trigger enhanced due diligence. This is again a regulatory requirement, not a discretionary one.

The purpose of the business relationship

KYB is not limited to document verification. The institution also needs to understand what the client does, what the account will be used for, and what transaction volumes and patterns to expect. This is partly a regulatory requirement and partly operational: without a baseline understanding of expected activity, the transaction monitoring system cannot calibrate effectively.

A new client that provides a clear business description, an explanation of their payment flows, and an indication of expected volumes will typically complete onboarding more quickly than one where the institution has to piece that picture together through follow-up questions.

Maintaining the record through the relationship

KYB is not a one-time check. Under the regulations, firms must keep their client records current. A change in ownership, a new director, or a significant change in business activity may trigger a refresh of the KYB documentation. This is sometimes called periodic review or ongoing due diligence.

Proactively notifying the account provider of material changes, rather than waiting to be asked, keeps the relationship running smoothly and reduces the risk of an account being restricted pending a documentation update.

DigiDoe's approach to complex structures

DigiDoe describes one of its distinguishing features as the ability to onboard complex structures that other institutions decline. This is grounded in the compliance infrastructure required to do it: a KYB process designed for multi-layer corporate structures, multi-jurisdiction ownership, and the documentation requirements that come with them.

Specific onboarding requirements, timelines and documentation lists are determined case by case. Nothing in this article is a guarantee of onboarding outcome or timelines. All client acceptance is subject to DigiDoe's risk appetite and applicable regulatory requirements.
