The 9 Best Free and Open Source Legal Software Tools

Lawyers are pretty famous for not doing anything for free. Turns out their software is similar. Beyond a couple standout options (detailed below), there’s not a ton of free and open source law practice management software. However, there are some free tools that, while not full-featured practice management systems, are nonetheless helpful in their own right.

Legal software can save attorneys tons of time on timekeeping and billing, creating documents and filling out forms, and managing contacts, correspondence, and calendaring. But whether you’re just starting up and trying to keep overhead low, or aren’t yet convinced software will be worth spending money on, you don’t want to shell out lots of dollars.

Keep in mind that “free” generally comes with costs. In the case of free legal software, one major cost is that none of the free versions are cloud-based. So keep in mind that you’ll need to download, host, setup, update and maintain your own installation.

And if you’re looking for additional free software, check out our lists for free contract management software and free and open source time tracking software.

Many, many software providers bill themselves as free when really only the trial is free. Undeterred, I found the two most popular open-source repositories, SourceForge and, list many legal/law practice options. Be warned, before you check them out, that many products on those lists are discontinued. Below are the best ones which appear to still be available for download.

Freemium Legal Software Options

1. CaseBox

CaseBox is an open-source, self-hosted document management, records management, and collaboration software solution. It’s listed in our Legal Case Management Software category.

Its features are a little lacking.


It’s got a cool backstory though. It was developed by HURIDOCS, a Geneva-based NGO that gives human rights defenders information technologies and documentation methods to organize and present data about violations.

To figure out if CaseBox is for you, email the team at to set up a consultation. If it’s not a great fit, the CaseBox team can make recommendations to help. If CaseBox is right for you, the team will cover the steps to implement CaseBox in your organization and will outline the services that HURIDOCS can provide, and provide an estimate of costs for these services.

2. Jarvis Legal

Jarvis Legal is another LPMS that offers an unlimited free version. The free version’s only caps are their case and data caps. You can have up to five simultaneous cases and use up to 5 GB of storage space. And 5 GB of data ain’t too shabby in terms of storage.

Capterra has Jarvis listed in our directory, and reviews for this software are a sparkling 4.5/5, and if you do choose to upgrade it’s only around $35 per user per month.

I’m also personally inclined to enjoy Jarvis Legal because of the name.

It’s very interesting! You may check another blog which I have read it on search. It Seems it’s similar to this article.


Nice article! Very usefull information about open source legal software. Thanks for sharing…


Zelican is a case management software for advocates & lawyers which helps right from client onboarding to invoicing. It has CaseTracker which updates about every single information quickly.


There are numerous law practice/case management soft wares available in the market covering various practice areas among which lawsyst practice management software is the one which i like the most. It also offers 30 days free trial.
For more information, we can check their website


There is another software total practice which is quite new and cloud based. Also, it is free and bundled with many other features. You should definitely check it out


You should mention Casebox. It looks really good and is a medical management document system.


Legal Suite does not appear to be free either. 30 day free trial, but I can’t even add in a client name that I can find. It’s greyed out and doesn’t take if I type a name in there and select save.

[…] course, the marketplace offers dozens of other software tools for the legal field. Capterra has a nice short list of free legal software here, and this blog post from 2011 might be out of date, but it offers an extensive list of applications […]


Great article, just a heads up for those reading this a year later it looks like esquire is no longer free unfortunately.


Great article! I had never heard of HoudiniEsq. until this article. Have you had any experience with troubleshooting while running open source software? My fear is that something in the software might break, and I will be unable to find tech support to fix it.


You should mention Casebox. It looks really good and is a management document system and colaborative tool too. Open Source.


Conflict Finder has nothing to do with law. Searching Wikipedia for conflicts of interest is a futile endeavor.
