California Code of Civil Procedure 437c: Summary Judgment Motions

California Code of Civil Procedure section 437c is the statute that governs summary judgment and summary adjudication in California civil cases. It lets a party ask the court to decide all or part of a lawsuit before trial, and the court will grant that request only when there is no genuine dispute about any fact that matters to the outcome. Because the procedure can end a case without a jury, the statute imposes strict rules on burdens, evidence, deadlines, and the format of every filing. Getting any of those wrong tends to matter more than the underlying merits.

What Section 437c Actually Does

The statute authorizes two related but distinct forms of relief. Summary judgment disposes of the entire case. If the court grants it, a final judgment is entered and the lawsuit is over. Summary adjudication knocks out only specific pieces while the rest of the case continues toward trial.

Under subdivision (f)(1), summary adjudication can target individual causes of action, affirmative defenses, claims for punitive damages under Civil Code section 3294, or issues of duty (whether a defendant owed the plaintiff a legal duty at all). Whatever it targets, the motion must completely dispose of that item. A court cannot grant partial summary adjudication that leaves part of a single cause of action alive while eliminating the rest.¹

Adjudication is useful for narrowing a sprawling case. If a plaintiff pleads five causes of action and two have no factual support, a defendant can eliminate the two and try the remaining three.

One Motion, One Chance

A party gets one shot at summary judgment against each opposing party. Subdivision (a)(4) prohibits a second summary judgment motion against the same adversary. The limit does not apply to summary adjudication, so multiple adjudication motions targeting different causes of action or defenses are permitted.¹

The practical consequence is that the first motion is the only motion. A denial cannot be refiled with better evidence or a sharper argument. The only remaining path is a motion for reconsideration under CCP section 1008, which requires new or different facts, circumstances, or law that could not have been presented earlier.

How the Burden Shifts

Summary judgment runs on a two-step burden. The moving party goes first. If it meets its initial burden, the burden flips to the opposing party. The mechanics differ depending on who is moving.

Defendant as the Moving Party

A defendant meets its initial burden by showing that at least one element of the plaintiff’s claim cannot be established, or by proving a complete defense. Disproving the entire case is not required. Knocking out a single required element is enough, because a cause of action fails if any element is missing.¹

Once the defendant makes that showing, the burden shifts to the plaintiff to produce specific, admissible evidence creating a genuine dispute over that element. Bare allegations in the complaint are not enough. The plaintiff has to come forward with declarations, deposition testimony, documents, or other evidence showing a reasonable fact-finder could rule in its favor.

Plaintiff as the Moving Party

A plaintiff carries a heavier initial burden. Under subdivision (p)(1), the plaintiff must affirmatively prove every element of the cause of action. There is no shortcut of negating a single defense. If the plaintiff clears that bar, the burden shifts to the defendant to raise a triable issue on any element or to show a viable defense exists.¹

At the shifted-burden stage, the defendant cannot rest on the denials in its answer. Specific facts showing a genuine dispute are required.

Evidence and the Separate Statement

The motion lives or dies on the paperwork. California courts are rigid about formatting, and technical failures sink motions regardless of the merits.

Supporting Evidence

All evidence submitted with the motion must be in a form admissible at trial. The statute allows declarations, admissions, answers to interrogatories, deposition transcripts, and matters subject to judicial notice. Declarations must be based on the declarant’s personal knowledge, not on speculation, hearsay, or secondhand information.¹

The Moving Separate Statement

The motion must include a separate statement listing every material fact the moving party contends is undisputed. Each fact is numbered, and each is followed by a citation to the specific evidence supporting it. This is not optional. Courts routinely deny motions that lack a proper separate statement or that bundle multiple facts into one entry.²

The Opposing Separate Statement

The opposition files its own separate statement responding to each listed fact, indicating whether it agrees or disagrees that the fact is undisputed. Any disputed fact must be accompanied by a citation to evidence supporting the dispute. The opposition can also add its own material facts it contends are disputed. Failing to file a compliant opposing separate statement can, by itself, give the court grounds to grant the motion.¹

Evidentiary Objections

Both sides can object to the other’s evidence. Under California Rules of Court, Rule 3.1354, written objections must be filed separately from the opposition or reply, served at the same time, numbered consecutively, and must quote the challenged material, identify its exact location, and state the legal grounds.³ Under subdivision (q), the court need only rule on objections it considers material to the outcome. Objections the court does not rule on are automatically preserved for appeal.¹

The Deadlines

Summary judgment deadlines are among the most unforgiving in California civil procedure. Missing one by a day can result in a motion being denied or an opposition rejected.

Hearing Date

The hearing must be set no later than 30 days before trial, unless the court orders otherwise for good cause. That timing ensures the case is resolved or narrowed well before the parties prepare for trial.¹

Notice Period and Service Extensions

The moving party must serve the notice of motion and all supporting papers at least 81 days before the hearing. That 81-day minimum assumes personal service. Other methods add time:

Mail within California: add 5 calendar days (86 total)
Mail outside California but within the U.S.: add 10 calendar days (91 total)
Mail outside the U.S.: add 20 calendar days (101 total)
Fax, express mail, or overnight delivery: add 2 court days

These extensions are built into the statute. Subdivision (b)(6) provides that the general time-extension provisions in CCP sections 1005 and 1013 do not apply to summary judgment motions, except for the method of service of opposition and reply papers. You cannot stack additional extensions on top of the ones already in the statute.¹

Opposition and Reply

Opposition papers must be filed and served at least 20 days before the hearing. The moving party’s reply is due at least 11 days before the hearing. Replies cannot introduce new evidence or new material facts; they are limited to responding to the opposition.¹

Continuances Under Subdivision (h)

Sometimes the party opposing summary judgment has not had enough time to gather the evidence it needs. Subdivision (h) addresses this directly: if the opposing party’s declarations show that essential facts may exist but cannot yet be presented, the court can deny the motion, grant a continuance for further discovery, or make any other order it considers just.¹

A continuance request can be made by ex parte motion at any time on or before the date opposition is due. Courts look closely at whether the requesting party was diligent in pursuing discovery before the motion was filed, how long the case has been pending, how close trial is, and whether the evidence sought is truly essential.

The Court’s Order

After the hearing, the court must issue an order explaining its reasoning. On a grant, the court specifies why no triable issue of material fact exists, referencing the specific evidence submitted. On a denial, the court must identify which material facts it found to be genuinely disputed and point to the evidence on both sides. The order can be written or oral, but must be recorded by a court reporter or in a written order.¹

The requirement exists to create a clear record for any appeal or writ petition. A vague order that simply says “motion granted” is not enough under the statute.

What Happens After the Ruling

Appealing a Summary Judgment

A summary judgment is a final judgment and can be appealed immediately. The Court of Appeal reviews the trial court’s decision de novo, applying the same standard the trial court used and giving no deference to its reasoning.

Challenging a Summary Adjudication Order

An order granting summary adjudication is not a final judgment because parts of the case remain active, so it cannot be appealed directly. The affected party can petition the Court of Appeal for a writ within 20 days after being served with written notice of entry. The same service extensions that apply to the 81-day notice also apply here: 5 extra days for mail within California, 10 for mail elsewhere in the U.S., 20 for international mail, and 2 court days for overnight or express delivery. The trial court can extend the filing period for good cause by up to 10 additional days.¹

Writ review is discretionary. Courts of Appeal grant it sparingly, so this path is far less reliable than a direct appeal.

Motion for Reconsideration

If a motion is denied and the moving party believes new facts or law have emerged, CCP section 1008 allows a motion for reconsideration within 10 days of being served with notice of entry of the order. The motion must be supported by a declaration explaining what new or different facts, circumstances, or law justify a different result. Repackaging the same arguments with better briefing will not satisfy the statute.⁴

Between the one-motion limit and the strict “new facts” standard for reconsideration, the message is the same from either side of the caption: the first motion is the one that counts, and it should be built accordingly.
