California Codes, Code of Civil Procedure - CCP, Part 2 — Of Civil Actions, Title 14 — Of Miscellaneous Provisions, Chapter 5 — Notices, and Filing and Service of Papers, Section 1010

Notices must be in writing, and the notice of a motion, other than for a new trial, must state when, and the grounds upon which it will be made, and the papers, if any, upon which it is to be based. If any such paper has not previously been served upon the party to be notified and was not filed by him, a copy of such paper must accompany the notice. Notices and other papers may be served upon the party or attorney in the manner prescribed in this chapter, when not otherwise provided by this code. No bill of exceptions, notice of appeal, or other notice or paper, other than amendments to the pleadings, or an amended pleading, need be served upon any party whose default has been duly entered or who has not appeared in the action or proceeding.
