Our case for why you should switch

OneAdvanced Legal is the UK’s number one legal platform offering SaaS-based freedom and flexibility, round-the-clock local support: turning productivity into profitability.

This matters because while we’re building for UK law firms, other vendors are retrofitting international solutions to meet your needs and UK legal compliance. It’s why we built ours around SRA, SAR, and Law Society requirements from day one, why our legal accounts software sits inside your case management platform, why our AI is UK-sovereign and built within our platform, and why we champion per-user SaaS pricing that scales with your ambition.

The numbers speak for themselves…

Four reasons to switch to the UK's number one legal platform

Our legal software is built to answer the key challenges law firms have and focus on client service delivery.

Reclaim hours spent on multiple entry

Outdated systems waste 8-12 hours per week per lawyer on manual data entry, compliance checking, and searching or documents. Competitors make you stitch together multiple systems for compliance as well as bolt-ons for forms, accounts and other necessary parts of case management.

Unlock greater efficiency and accuracy for your firm with OneAdvanced Legal. Our unified platform brings all your essential tools together, reducing manual work and errors so your team can focus on what matters most. Further empower your team with AI-powered solutions that simplify daily tasks—from client communications, meeting summaries legal-specific compliance agents, and more.

Upgrade your legal AI tools

AI that's UK-sovereign and integrated; not a bolt-on

Many vendors offer AI solutions but many are not legal-specific or UK-sovereign, leaving questions around data security and workflow integration.

OneAdvanced AI in the OneAdvanced Legal platform, provides safe and secure AI with a comprehensive agents library and legal-specific agents such as our legal compliance AI agents; combining automated file reviews with matter-quality insights and turning hours of admin into minutes while delivering actionable insights and driving firm-wide impact.

OneAdvanced also has ISO 42001 certification, the new international standard for Artificial Intelligence Management Systems, so you know your data is secure in our AI.

    Choose a legal platform that gives you freedom, flexibility and predictability.
