Verdict at a glance

Recommended for

Solos and small firms that need affordable case law, statutes and a citator.

Bottom line

Check your bar first; if it offers Decisis, you may already have it. Solos and two-lawyer firms without a bar benefit can buy online after a 7-day trial.

A cost-focused primary-law research database: state and federal appellate case law, nationwide statutes, regulations and court rules, and the InterCite citator. Premium adds federal district and bankruptcy decisions; Premium Plus adds forms, dockets for 1,400+ courts, news, case analytics and state trial court orders. It's free through many state bars. Online purchase is limited to one- and two-attorney firms, and plans appear to be annual subscriptions.

Not for

Firms that rely on treatises, secondary sources and editorial headnotes, and firms of three or more lawyers wanting to buy online.

Pricing from

Free through many state bars; online plans for 1–2 attorney firms; prices not published (not displayed on decisis.com/purchase, checked 2026-10-15); ask Decisis for small-firm pricing in writing

Pros

  • Free through many state bars (decisis.com)
  • InterCite citator included on every plan (decisis.com)
  • Premium Plus adds forms and dockets for 1,400+ courts (decisis.com)
  • 7-day free trial (decisis.com)

Cons

  • Online purchase only for one- and two-attorney firms
  • Online plans appear to be annual commitments
  • No treatises or secondary sources
  • Bar-benefit versions may not include every Premium Plus feature

Quick answer

Bottom line: Decisis is for solos and small firms that need affordable case law, statutes and rules with a citator, and for any lawyer whose bar already provides it. It's free through many state bars, so check yours first. If your bar doesn't offer it, one- and two-attorney firms can buy online after a 7-day free trial. Prices aren't published: they didn't display on the purchase page when we checked (October 15, 2026), so ask Decisis for small-firm pricing in writing. The trap: bar versions may not include Premium Plus features such as dockets and forms, and online plans appear to be annual commitments.

What this means for you: a citator shows whether a case is still good law. Ask your bar which package it provides before paying to upgrade.
