Pleadings, motions, discovery, and other case documents are required to be "served" on parties in a lawsuit. This simply means that everybody gets a copy of everything in time to take action before something happens, like file opposition to a motion. There are rules that govern how these things are "served" or, in plain English, are sent. The rules differ by state and court system, and to make matters worse, they are complicated and spread among many different sources of law, such as federal statutes and cases, state statutes and cases, state judicial council rules, county court rules, and individual judges' rules. The remainder of this section focuses on only California state laws. If you need the laws of another state, you must consult with a lawyer in that state.

Particular California statutes
When to give notice or file opposition (CCP 1005.5) ("Unless otherwise ordered or specifically provided by law, all moving and supporting papers shall be served and filed at least 16 court days before the hearing. The moving and supporting papers served shall be a copy of the papers filed or to be filed with the court. However, if the notice is served by mail, the required 16-day period of notice before the hearing shall be increased by five calendar days if the place of mailing and the place of address are within the State of California, 10 calendar days if either the place of mailing or the place of address is outside the State of California but within the United States, and 20 calendar days if either the place of mailing or the place of address is outside the United States, and if the notice is served by facsimile transmission, express mail, or another method of delivery providing for overnight delivery, the required 16-day period of notice before the hearing shall be increased by two calendar days. Section 1013, which extends the time within which a right may be exercised or an act may be done, does not apply to a notice of motion, papers opposing a motion, or reply papers governed by this section. All papers opposing a motion so noticed shall be filed with the court and a copy served on each party at least nine court days, and all reply papers at least five court days before the hearing. [Par.] The court, or a judge thereof, may prescribe a shorter time."
