You asked
Is it only for courts?
The short answer
No. It covers the whole government on one record model, turned on one part at a time: enrollment, council, courts, finance, and land. You start with the part that needs it most and leave the rest as it is until you are ready.
The same record model runs every part of your government. You turn on the one that matters most first, and each step builds on the last, so nothing is thrown away.
Because it is one system, a member's enrollment, cases, and fees are already linked the day a second department turns on.
