Decisis Legal Research

Updated 2026-03-19
What it is Overview

Legal research platform powered by LexisNexis, offered as a bar association member benefit. Successor to Fastcase as the primary bar-association-provided legal research tool (Oregon State Bar migrated from Fastcase to Decisis in September 2024). Bar association partners include: Ohio Bar, Colorado Bar, Indiana State Bar, Massachusetts Bar, Oregon State Bar, Philadelphia Bar, Pennsylvania Bar, Mississippi State Bar, Mecklenburg Bar Association, and others. Features: streamlined legal research with tailored search filters, massive primary law database (state and federal case law), citator for citation verification, training on-demand. Backed by same parent company as LexisNexis (RELX). Free to bar association members. Essentially a LexisNexis sub-brand/white-label for the bar association channel that was previously served by Fastcase before the acquisition.
