Interoperability of legal tools

Interoperability of legal tools is the ability of the various IT systems used by legal professionals to communicate, exchange data and work together seamlessly. In practical terms, in an interoperable firm or legal department, the matter management software, the electronic signature tool, the CLM, the case law database and the AI assistant all share information without anyone having to manually re-enter data from one system into another.

This interoperability relies primarily on APIs (Application Programming Interfaces) and, increasingly, on the MCP protocol (Model Context Protocol), which standardises the connections between AI models and external tools. Without interoperability, each tool operates in a silo, generating duplicate data entry, error risks, considerable wasted time and user frustration that hampers adoption.

The lack of interoperability is identified as the single biggest barrier to legaltech adoption in smaller organisations (solo practitioners and small partnerships). To address this, vendors of legal solutions are building native connectors, integration marketplaces and open APIs. Law firms and legal departments should treat interoperability as a top-priority criterion when selecting their tools.
