6 Legaltech Platforms Using Open Banking to Modernise Law Firm Workflows in 2025

The legal sector has historically been slow to adopt financial technology, but that’s changing fast. A new wave of legaltech platforms is using Open Banking to help law firms cut delays, reduce manual reviews, and meet growing compliance demands without the paperwork.

Instead of relying on PDF bank statements or waiting days for income proof, legal teams can now use real-time, bank-verified data to run Source of Funds checks, AML risk scoring, and client onboarding, all through secure, consent-based flows.

This isn’t just innovation for innovation’s sake. With tighter SRA, CLC, and HMRC scrutiny, law firms need digital compliance tools that deliver speed, accuracy, and defensibility. Open Banking meets that standard, and these six trusted legaltech platforms are already showing how it fits into everyday legal workflows.

In this guide, we’ll break down exactly how each provider uses Open Banking, what legal use cases they serve best, and why these tools are becoming essential for modern law firms.
