rules of court
n. a set of procedural regulations adopted by courts which are mandatory upon parties and their lawyers on matters within the jurisdiction of those courts. Most states have statewide rules of court. Federal court rules are adopted by the district courts based on the Federal Rules of Procedure, and county, district and municipal court judges adopt what are called "local rules" of court. Local rules encompass the time allowed to file papers, the format of documents (including the paper colors of appeal court briefs), the number of copies to be filed, the procedure to file motions, the basis for calculating alimony and child support, fees for filing various documents and numerous other mundane but vital matters. These rules are violated or ignored at the peril of the client and his/her/its counsel.
