Jury trial waivers in California work differently depending on when and how they happen. A clause buried in a contract you signed before any dispute arose is unenforceable in California state court. A waiver that happens during litigation — because someone missed a fee deadline or failed to demand a jury on time — is enforced, though a judge has discretion to grant relief.
That split is the whole answer, and it comes from the California Constitution. The jury right is “inviolate,” and it can only be waived “by the consent of the parties expressed as prescribed by statute.”1Justia. California Constitution Article I Section 16 – Declaration of Rights Those last five words are what make contract waivers fail and procedural ones stick.
Contract Clauses Waiving a Jury Are Not Enforceable
The California Supreme Court decided this in Grafton Partners L.P. v. Superior Court (2005) 36 Cal.4th 944. Code of Civil Procedure section 631 lists the ways a party can waive a jury, and the court held that list is exclusive. A pre-dispute contractual clause is not on it, so it has no legal effect.2California Supreme Court Resources. Grafton Partners v. Sup. Ct.
The court’s reasoning tracks the statute. Every method section 631 authorizes “strongly suggests that waiver of the right to jury trial must occur subsequent to the initiation of a civil lawsuit.”2California Supreme Court Resources. Grafton Partners v. Sup. Ct. Written consent has to be filed with the clerk. Oral consent has to be entered in the court minutes. Fee deadlines are tied to case management conferences. None of that machinery exists before a lawsuit is filed, so a signature on a contract cannot satisfy it.
The rule is categorical. It does not matter how sophisticated the parties are, whether both sides had lawyers, or whether the waiver language was bold, capitalized, and initialed. A clause that says “the parties waive the right to a jury trial for any dispute arising under this agreement” is unenforceable in California state court.
Arbitration Agreements Are a Different Thing
This is where the confusion usually starts. Arbitration clauses signed before a dispute are routinely enforced in California, and arbitration eliminates the jury just as effectively as a waiver clause would. The difference is statutory backing. The Federal Arbitration Act and the California Arbitration Act specifically authorize pre-dispute agreements to move disputes out of court entirely. A jury waiver clause that keeps the case in court but strips out the jury has no equivalent authority behind it.
The practical result: if a business wants to avoid juries through contract, it has to require arbitration. A clause saying “all disputes will be tried to a judge, not a jury” fails. A clause saying “all disputes will be resolved through binding arbitration” generally holds up.
Choice-of-Law Clauses Don’t Rescue the Waiver
Some contracts pick the law of a state that does enforce pre-dispute jury waivers, like Delaware or New York, hoping to sidestep Grafton. California courts have refused to go along. In William West v. Access Control Related Enterprises, LLC (2020), a Los Angeles Superior Court declined to apply a Delaware choice-of-law provision because doing so would strip a California resident of the constitutional jury right. The waiver was unenforceable regardless of what the contract said about which state’s law applied.
How You Can Still Lose the Right During a Case
Section 631 does authorize waivers, just not contractual ones. Once a lawsuit is on file, there are six ways a party can lose the jury right, and courts treat the list as exhaustive.
- Failing to appear at trial.3California Legislative Information. California Code CCP 631
- Filing written consent to waive with the clerk or judge.
- Giving oral consent in open court, entered in the minutes.
- Failing to announce that a jury is required when the case is set for trial. If the case is set on notice or stipulation, the announcement has to happen then; if set without notice, you have five days after receiving the setting notice.
- Failing to pay the initial jury fee. At least one party on each side demanding a jury has to pay a nonrefundable $150 fee on or before the initial case management conference.3California Legislative Information. California Code CCP 631
- Failing to deposit the daily session fee. Starting the second day of trial, the fee is due at the beginning of each session.
The $150 fee is where most waivers actually happen. The deadline is the case management conference, which in many courts is scheduled months before trial, and the waiver is automatic if nobody pays. Another party on the same side can cover it for you, but relying on that is a mistake. Lawyers and pro per litigants alike have discovered they lost the jury only when they went to set the trial and found the case designated as a bench trial.
If the Case Moves to Federal Court
Removal to federal court adds its own trap. Under Federal Rule of Civil Procedure 81, a party who already made an express jury demand in state court does not need to renew it.4Legal Information Institute (Cornell Law School). Rule 81 – Applicability of the Rules in General; Removed Actions But if all pleadings had been served before removal and no demand was on file, a party wanting a jury has 14 days from the filing or service of the removal notice to file one under Rule 38.5Legal Information Institute (Cornell Law School). Rule 38 – Right to a Jury Trial; Demand Miss that window and the right is gone.
Federal courts are generally more receptive to pre-dispute contractual jury waivers than California courts are, so long as the waiver was knowing and voluntary. The Ninth Circuit, however, has held that federal courts sitting in diversity apply state law on jury waivers when the state law is more protective of the jury right. That means a California-law contract with a jury waiver clause remains unenforceable in Ninth Circuit federal courts. In other circuits, the same clause could be enforced.
Getting a Procedural Waiver Undone
A missed deadline is not necessarily the end. Section 631(g) gives the trial court discretion to grant relief from a waiver “upon just terms.”3California Legislative Information. California Code CCP 631 California has a strong policy favoring jury trials, and courts routinely use this provision to excuse honest mistakes.
What courts look at: how long the delay was between the waiver and the request for relief, whether the party moved quickly once it realized what happened, whether the other side would be prejudiced by switching to a jury, and whether the court’s calendar can absorb the change. An inadvertent waiver — a calendaring error on the fee, for instance — is far easier to undo than a deliberate waiver a party wants to reverse for tactical reasons. Appellate review is for abuse of discretion, which is a hard standard to meet, so the trial court’s decision is usually the last word.
If you find out that a fee was missed or a demand was not filed, file the motion for relief immediately. Courts are noticeably more forgiving to parties who act the same week they discover the problem than to those who wait a month or two hoping the issue will resolve itself.
