Full Text of § 581
Plain-English Summary
This section does double duty: it defines the vocabulary the rest of the dismissal statutes use, and it lays out most of the ways a California civil action can end short of a judgment on the merits. Its definitions reach further than the everyday meaning of the words — "action" covers special proceedings too, "complaint" includes a cross-complaint, "defendant" includes a cross-defendant, and a trial is deemed to commence at the opening statement, or at the swearing of the first witness, or the introduction of evidence if there's no opening statement.
Before trial starts, dismissal is largely in the plaintiff's hands. A plaintiff can dismiss the complaint, or any cause of action in it, entirely or as to particular defendants, with or without prejudice, by filing a written request or asking the court, and paying any costs due. All parties together can also stipulate to dismissal, with or without prejudice. The court can dismiss without prejudice when nobody appears for trial after 30 days' notice, when either party fails to appear and the other asks for dismissal, or when dismissal follows the delay-based rules of Chapter 1.5 (§ 583.110 and following).
Once trial has begun, the rules tighten. If the plaintiff abandons the case before final submission, the court must dismiss with prejudice — that's the default consequence of quitting partway through. Subdivision (e) softens that only slightly for a plaintiff-requested dismissal after trial starts: it's still with prejudice unless all affected parties consent to a dismissal without prejudice, or the court finds good cause to order it without prejudice anyway. The section also covers dismissals following a sustained demurrer or granted motion to strike where the plaintiff doesn't amend in time, requires an attorney's consent (or notice to the attorney) before certain voluntary dismissals, and bars dismissal of a certified class action without adequate notice and court approval.
Frequently Asked Questions
Can a plaintiff dismiss a case any time before trial starts?
Yes. Section 581(b)(1) lets the plaintiff dismiss, with or without prejudice, by written request to the clerk or by request to the court at any time before trial commences, upon payment of any costs owed.
When is a trial considered to have "commenced" for purposes of this section?
At the beginning of the opening statement or argument, or, if there's no opening statement, when the oath is administered to the first witness or evidence is first introduced.
What happens if a plaintiff abandons the case mid-trial?
Except where subdivision (e) applies, the court must dismiss the complaint with prejudice if the plaintiff abandons it after trial has commenced and before the case is finally submitted.
Can a plaintiff still get a dismissal without prejudice after trial has started?
Only if all affected parties consent to it, or the court finds good cause to order dismissal without prejudice under subdivision (e).
Does a plaintiff need anyone else's consent to voluntarily dismiss under this section?
Often yes — subdivision (j) generally requires the written consent of the party's own attorney, or notice to the attorney if consent can't be obtained, before certain voluntary dismissals can be entered.
