Creating municipal courts

Municipalities may join together to form one court. The contracting municipalities need not be contiguous or even in the same county. Any number of municipalities may join and voters in all the municipalities elect the judge.

A packet entitled Starting a Municipal Court is available to assist municipalities interested in creating municipal courts. It contains statistics about municipal courts, sample ordinances, answers to commonly asked questions, ethics advice and general information. The guide is continuously updated and distributed to municipalities upon request.
