One Legal An Infotrack Company

What It Does

One Legal is a court eFiling and service-of-process platform for California law firms. It handles electronic court filing, process serving, and courtesy-copy delivery across all 58 California counties, and integrates with case-management systems including Clio Manage. The company was founded in 1990 and was acquired by InfoTrack in March 2020; it now operates as part of InfoTrack’s US legal-technology group.

Who It’s For

One Legal fits the filing/court-submission stage of the litigation workflow for California-based firms of any size — solos through large firms — that need to eFile and serve documents. Firms outside California will get less from it, since coverage is California-specific.

What We Found

One Legal states it assists tens of thousands of law firms with document delivery. It carries customer reviews on Trustpilot and is documented through InfoTrack’s own announcements of the acquisition. The Clio Manage integration is verified. Within the InfoTrack group, One Legal is the California-focused court-filing brand.

What We Haven’t Verified
