Cal. Code of Civil Procedure - CCP § 446. Section 446.
(a)
Every pleading shall be subscribed by the party or his or her attorney. When the state, any county thereof, city, school district, district, public agency, or public corporation, or any officer of the state, or of any county thereof, city, school district, district, public agency, or public corporation, in his or her official capacity, is plaintiff, the answer shall be verified, unless an admission of the truth of the complaint might subject the party to a criminal prosecution, or, unless a county thereof, city, school district, district,
public agency, or public corporation, or an officer of the state, or of any county, city, school district, district, public agency, or public corporation, in his or her official capacity, is defendant. When the complaint is verified, the answer shall be verified. In all cases of a verification of a pleading, the affidavit of the party shall state that the same is true of his own knowledge, except as to the matters which are therein stated on his or her information or belief, and as to those matters that he or she believes it to be true; and where a pleading is verified, it shall be by the affidavit of a party, unless the parties are absent from the county where the attorney has his or her office, or from some cause unable to verify it, or the facts are within the knowledge of his or her attorney or other person verifying the same. When the pleading is verified by the attorney, or any other person except one of the parties, he or she shall set forth in the affidavit the reasons why it is not made by one of
the parties.
When a corporation is a party, the verification may be made by any officer thereof. When the state, any county thereof, city, school district, district, public agency, or public corporation, or an officer of the state, or of any county thereof, city, school district, district, public agency, or public corporation, in his or her official capacity is plaintiff, the complaint need not be verified; and if the state, any county thereof, city, school district, district, public agency, or public corporation, or an officer of such state, county, city, school district, district, public agency, or public corporation, in his or her official capacity is defendant, its or his or her answer need not be verified.
When the verification is made by the attorney for the reason that the parties are absent from the county where he or she has his or her office, or from some other cause are unable to verify it, or when the
verification is made on behalf of a corporation or public agency by any officer thereof, the attorney’s or officer’s affidavit shall state that he or she has read the pleading and that he or she is informed and believes the matters therein to be true and on that ground alleges that the matters stated therein are true. However, in those cases the pleadings shall not otherwise be considered as an affidavit or declaration establishing the facts therein alleged.
A person verifying a pleading need not swear to the truth or his or her belief in the truth of the matters stated therein but may, instead, assert the truth or his or her belief in the truth of those matters “under penalty of perjury.”
(b)

1993–94 Regular Session.
