Decisis Legal Research

Updated 2026-03-19

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.

Research & Analysis

What practitioners struggle with

Real frustrations from legal professionals — the problems Decisis Legal Research addresses (or should address). Sourced from practitioner reviews, Reddit threads, and case studies.

Legal research costs $400-600/hour in associate time and takes hours of manual digging — searching Westlaw/Lexis, reading irrelevant results, synthesizing case law. Clients increasingly refuse to pay for research hours on invoices. AI can compress a 4-hour research memo into 20 minutes, but most firms have no approved tool

Solo/small firm needs case law research but Westlaw and LexisNexis charge $300-500/month per user — either pay and bleed, negotiate a discount every year, or go without and risk missing relevant authority. Free alternatives (Google Scholar, Fastcase) have gaps in coverage and no citator
