Cal. Rules of Court, rule 3.1332

(a) Trial dates are firm

To ensure the prompt disposition of civil cases, the dates assigned for a trial are firm. All parties and their counsel must regard the date set for trial as certain.

(b) Motion or application

A party seeking a continuance of the date set for trial, whether contested or uncontested or stipulated to by the parties, must make the request for a continuance by a noticed motion or an ex parte application under the rules in chapter 4 of this division, with supporting declarations. The party must make the motion or application as soon as reasonably practical once the necessity for the continuance is discovered.

(c) Grounds for continuance

Although continuances of trials are disfavored, each request for a continuance must be considered on its own merits. The court may grant a continuance only on an affirmative showing of good cause requiring the continuance. Circumstances that may indicate good cause include:

(1) The unavailability of an essential lay or expert witness because of death, illness, or other excusable circumstances;

(2) The unavailability of a party because of death, illness, or other excusable circumstances;

(3) The unavailability of trial counsel because of death, illness, or other excusable circumstances;

(4) The substitution of trial counsel, but only where there is an affirmative showing that the substitution is required in the interests of justice;

(5) The addition of a new party if:

(A) The new party has not had a reasonable opportunity to conduct discovery and prepare for trial; or

(B) The other parties have not had a reasonable opportunity to conduct discovery and prepare for trial in regard to the new party's involvement in the case;

(6) A party's excused inability to obtain essential testimony, documents, or other material evidence despite diligent efforts; or

(7) A significant, unanticipated change in the status of the case as a result of which the case is not ready for trial.

(d) Other factors to be considered

In ruling on a motion or application for continuance, the court must consider all the facts and circumstances that are relevant to the determination. These may include:

(1) The proximity of the trial date;

(2) Whether there was any previous continuance, extension of time, or delay of trial due to any party;

(3) The length of the continuance requested;

(4) The availability of alternative means to address the problem that gave rise to the motion or application for a continuance;

(5) The prejudice that parties or witnesses will suffer as a result of the continuance;

(6) If the case is entitled to a preferential trial setting, the reasons for that status and whether the need for a continuance outweighs the need to avoid delay;

(7) The court's calendar and the impact of granting a continuance on other pending trials;

(8) Whether trial counsel is engaged in another trial;

(9) Whether all parties have stipulated to a continuance;

(10) Whether the interests of justice are best served by a continuance, by the trial of the matter, or by imposing conditions on the continuance; and

(11) Any other fact or circumstance relevant to the fair determination of the motion or application.
