Legal know-how, good communication skills and a strong (paying) client base remain the linchpins of any law practice. But another critical piece of a modern law firm is information technology.

In 2004, after 23 years as a senior litigator in a midsize law office, I decided to open my own firm and run it with entirely free and open source software. FOSS is free from licensing fees, free to modify and customize it to your law practice and “open” in the sense that the software is neither weighed down with proprietary code nor confined by a one-size-fits-all modus operandi.
