Financial institutions are sitting on a mounting compliance problem. Across the sector, customer files are frequently inaccurate, out of date, and riddled with gaps that regulators now regard as non-negotiable.
According to KYC360, as regulatory pressure continues to intensify, firms are increasingly being forced to confront large-scale know-your-customer (KYC) remediation projects they had hoped to defer.
KYC360 recently discussed KYC remediation for legacy customer files, and how to reduce risk for smoother compliance.
The Financial Action Task Force’s (FATF) recommendations on customer due diligence provide a comprehensive framework that has evolved considerably since many legacy files were first created. Institutions that have built large customer books under older frameworks, grown through mergers and acquisitions, or developed correspondent banking relationships across multiple jurisdictions face a particular challenge. In the UK, the FCA’s anti-money laundering (AML) and KYC requirements place clear obligations on firms to keep customer records accurate and current.
Legacy records frequently fall short of those obligations. Files created under older onboarding standards may be missing ultimate beneficial ownership (UBO) information, documented source of wealth, up-to-date politically exposed person (PEP) screening results, and consistent risk classifications. These gaps may once have been acceptable, but no longer meet the standard regulators now expect.
The challenge is compounded when institutions attempt to launch remediation campaigns to address these shortfalls. Customer records are often spread across disconnected systems, with no single source of truth. Audit trails are incomplete or inaccessible. Risk ratings assigned years ago may no longer align with current regulatory criteria, and customer risk profiles can shift faster than periodic review cycles are able to capture. Regulators increasingly expect proof of controls in action, not just policy documents — and major enforcement actions in recent years have been linked directly to poor record-keeping and an inadequate understanding of customer risk.
Manual remediation campaigns carry their own considerable risks. Legacy data problems typically stem from a combination of outdated onboarding frameworks, core banking infrastructure not designed for modern compliance demands, and the documentation inconsistencies introduced through historical M&A activity. When compliance teams attempt to address these issues through manual workflows, the results are often counterproductive. Data fragmentation across systems increases the likelihood of processing errors. Inconsistent interpretation of missing information leads to inconsistent decisions across the same customer population. High volumes of records create operational bottlenecks and backlogs that can take months to clear.
Auditability is a particular concern. Conducting remediation through a combination of emails and spreadsheets makes it extremely difficult to demonstrate that a campaign was carried out consistently and in line with regulatory expectations. Regulators are not simply interested in outcomes — they want to understand how decisions were reached. There is also a resourcing dimension that compliance leaders frequently underestimate. Manual remediation is demoralising for analyst teams. Rekeying data across multiple systems and piecing together fragmented customer histories is not an efficient use of skilled resource. Analysts who could be investigating high-risk cases are instead managing administrative backlogs. Without clear workflow design and appropriate technology support, remediation programmes intended to fix legacy data problems can inadvertently introduce new ones.
According to KYC360, For AML teams preparing to tackle legacy customer files, a clear plan is essential. Risk-based segmentation should be the starting point.
Not all legacy files carry equal risk, and prioritising by jurisdiction, PEP indicators, existing risk ratings, and customer type before work begins ensures that resource is directed where regulatory exposure is greatest. From there, data requirements must be standardised across identity verification, beneficial ownership, source of funds, and risk scoring. Every remediated record should meet the same bar — inconsistency within the same campaign is itself a compliance risk.
Workflow automation plays a central role in effective remediation. KYC remediation software can support data validation, documentary verification, case management, and audit trail generation, said KYC360.
Automated solutions reduce the margin for human error and make it significantly easier to evidence consistent decision-making across large volumes of records. Clear governance must run throughout the programme — dashboards, escalation frameworks, defined roles and responsibilities, and regular reporting to senior compliance leadership are not optional at scale; they are what keeps a remediation programme on track and defensible.
Managing the customer dimension of a remediation campaign is equally important. Customers who have already provided documentation during onboarding are frequently less co-operative the second or third time around. Outreach fatigue is a genuine challenge: excessive or poorly timed contact gets ignored, and services may ultimately need to be restricted for unresponsive clients. The most effective programmes treat customer communication as a workstream in its own right, using phased outreach strategies to maximise engagement and, where possible, non-documentary validation to reduce friction.
Legacy customer records are a persistent compliance challenge, but they do not have to remain one. Approached strategically, KYC remediation campaigns can improve data integrity, strengthen AML frameworks, and reduce long-term compliance costs by building the processes needed to avoid large-scale remediation projects in future. Institutions that invest appropriately in technology and governance at the outset are better placed to build resilient compliance operations that can withstand whatever changes in the regulatory environment come next.
