Financial institutions operate under some of the toughest AML and KYC regimes in the world and as legal-sector supervision tightens, firms now have a real opportunity to draw on the maturity, discipline and technology practices that have long shaped banking compliance.
Learning from banking’s AML and KYC maturity
Widespread non-compliance among law firms with basic source-of-funds and source-of-wealth checks highlighted by the SRA’s own thematic review has shown that the existing supervisory model wasn’t driving consistent, risk-based AML standards across the legal sector. As a result, the government has chosen to shift AML supervision from the SRA to the FCA, aiming for stricter, more uniform enforcement and a level of oversight closer to what banks already operate under.
However, banks didn’t reach today’s level of discipline overnight. Since 2013, they have spent years developing risk-based frameworks that genuinely guide decisions, supported by consistent, evidence-led methodologies across onboarding, enhanced due diligence (EDD) and ongoing monitoring.
By contrast, many law firms still treat risk assessments as static admin tasks. With evidence of the levels of non-compliance within the industry, regulators now expect dynamic, data-driven risk management.
Governance is another area where banks set a clear benchmark: senior accountability is visible, MLROs are empowered, and compliance is treated as a strategic priority rather than an operational burden. It’s no coincidence that this level of leadership involvement is one of the strongest indicators of AML maturity.
Culture matters too. Banks embed AML and KYC awareness across the entire organisation, ensuring staff recognise red flags and understand the risks inherent in each client relationship. Law firms will increasingly need a similar approach shifting AML from a responsibility held by a few to a shared professional duty across partners, fee-earners and support teams.
Banks also excel at disciplined documentation. Every decision is captured, centralised and easy to evidence. Many law firms, however, still rely on fragmented, fee-earner-specific processes, which make demonstrating compliance far more difficult. And while banks have long treated monitoring as an ongoing obligation, law firms are only just starting to move away from annual reviews toward continuous supervision of client risks.
How law firms can prepare using banking KYC practices as a blueprint
Law firms can borrow heavily from the banking playbook starting with building structured, risk-sensitive onboarding processes that centralise due diligence rather than pushing responsibility onto individual fee-earners. Clear templates, escalation triggers and consistent documentation create both rigour and defensibility.
Risk frameworks should also be refreshed regularly, ensuring client, sector and geographic risks evolve with new information.
Auditability must become a priority. Banks maintain standardised, review-ready files; firms can mirror this by consolidating records into unified repositories and ensuring decisions are properly justified.
Finally, law firms should begin to replace periodic reviews with perpetual monitoring ensuring they catch new adverse media, PEP changes, shifts in beneficial ownership or emerging ESG or integrity risks as they happen. This approach aligns squarely with the expectations of an FCA-style supervisory model.
Why AI matters and how banks have already solved these challenges
Banks have embraced AI because manual processing simply couldn’t match the scale, complexity and speed of modern risk. Their experience offers a clear roadmap for law firms today.
AI-powered onboarding can be automated to verify identities, authenticate documents, uncover beneficial ownership and screen against sanctions and PEP lists. This not only reduces manual work but also injects consistency and objectivity into risk scoring.
For Enhanced Due Diligence (EDD), AI tools used in banking can pull multilingual adverse media, map associated networks, surface ESG or corruption risks and produce risk relevant structured reports in minutes. These capabilities directly address the rising expectations placed on law firms.
Continuous monitoring is another area where AI has reshaped compliance. Automated alerts flag emerging risks the moment they appear, and complete, timestamped audit trails make evidencing compliance straightforward rather than periodically. Crucially, AI enables banks to scale their AML and KYC capabilities without growing headcount at the same pace, a lesson with clear relevance for law firms facing heightened scrutiny.
Why this shift should be seen as an opportunity
Banks have already been through the transformation. The legal sector is now entering tougher expectations, clearer governance, more rigorous risk models and technology-driven compliance. Those that adapted early strengthened their market position.
Law firms that follow a similar path can do the same. Clients increasingly expect advisers to demonstrate strong governance, thoughtful risk management and credible due diligence. Firms that modernise now and enhance their frameworks with AI-enabled automation will be better placed to win complex work, serve cross-border clients and meet regulators’ expectations with confidence.
The Path Forward for UK Law Firms
As AML reform reshapes the UK legal landscape, banking offers a tested model for what effective compliance looks like. Strong governance, an embedded culture, structured KYC processes, reliable documentation, continuous monitoring and AI-powered technology form the backbone of resilient, future-ready AML operations.
By applying these lessons, law firms can turn regulatory change into a strategic advantage not just a compliance challenge.
