California Code of Civil Procedure 437c: Burdens, Deadlines, and Appeals

California Code of Civil Procedure section 437c is the statute that governs motions for 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 the evidence shows no genuine dispute over any fact that would change the outcome. Because a successful motion can end a case without a jury, section 437c sets strict rules about burdens of proof, admissible evidence, deadlines, and the exact format of the papers. A single misstep on any of those can sink an otherwise strong motion or a valid opposition.

What the Statute Lets You Ask For

Section 437c covers two different requests. Summary judgment disposes of the entire case: if the court grants it, a final judgment is entered and the lawsuit is over. Summary adjudication, under subdivision (f)(1), knocks out only specific pieces while the rest of the case continues toward trial.¹

Summary adjudication can target an individual cause of action, an affirmative defense, a claim for punitive damages under Civil Code section 3294, or an issue of duty. Whatever it targets, the motion has to completely dispose of that item. A court cannot grant partial adjudication that eliminates part of a single cause of action and leaves the rest alive.

One boundary matters before you file. Subdivision (a)(4) gives you exactly one motion for summary judgment against each opposing party. If it fails, you cannot refile with better evidence or a sharper argument. That limit does not apply to summary adjudication, so a party can bring multiple adjudication motions against different causes of action or defenses. Treat the first summary judgment motion as the only one you will get.

Who Has to Prove What

Section 437c runs on a two-step burden-shifting structure. The moving party goes first. If it meets its initial burden, the burden flips to the opposing party to show a triable issue of material fact. The specifics depend on which side is moving.

Defendant as the Moving Party

A defendant meets its initial burden by showing that at least one element of the plaintiff’s cause of action cannot be established, or by proving a complete affirmative defense. The defendant does not have to disprove the whole case. 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 plaintiff has to come forward with specific, admissible evidence creating a genuine dispute. Allegations in the complaint are not evidence. The plaintiff needs declarations, deposition testimony, documents, or other admissible proof that a reasonable fact-finder could use to 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 defendant has to raise a triable issue on any element or show a viable defense exists.¹

At the shifted-burden stage, the defendant cannot rely on denials in its answer. It has to present specific facts showing a genuine dispute remains.

The Evidence and the Separate Statement

Most summary judgment motions are won or lost on the paperwork. California courts enforce the formatting rules strictly, and technical failures can be fatal regardless of the underlying merits.

Supporting Evidence

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

The Moving Party’s Separate Statement

The motion has to include a separate statement listing every material fact the moving party contends is undisputed. Each fact gets its own numbered entry, followed by a citation to the specific evidence supporting it. Courts routinely deny motions that lack a proper separate statement or that bundle multiple facts into a single entry.²

The Opposing Separate Statement

The opposing party files its own separate statement responding to each listed fact. For every fact, the opposition has to say whether it agrees or disagrees that the fact is undisputed, and any disputed fact must be backed by a citation to evidence. The opposing party can also add material facts of its own that it contends are disputed. Failure to file a compliant opposing separate statement can, by itself, give the court grounds to grant the motion.¹

Objections to Evidence

Both sides can object to the other’s evidence. Under California Rules of Court, Rule 3.1354, written objections have to be filed separately from the opposition or reply papers and served at the same time. Each objection must be numbered consecutively, identify the specific document, exhibit, page, and line number of the material being challenged, quote the objectionable statement, and state the legal grounds.³

The court is not required to rule on every objection. Under subdivision (q), it only has to address objections it considers material to the outcome. Any objections the court does not rule on are automatically preserved for appeal.¹

Deadlines You Cannot Miss

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 being rejected.

Hearing Date

The motion must be set for hearing no later than 30 days before the trial date, unless the court orders otherwise for good cause.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. If the papers are served by another method, the statute adds 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 the statute already gives you.¹

Opposition and Reply

Opposition papers are due at least 20 days before the hearing. The moving party’s reply is due at least 11 days before the hearing. Reply papers cannot introduce new evidence or new material facts. The reply is strictly for responding to arguments and evidence raised in the opposition.¹

When the Opposing Party Needs More Time

Subdivision (h) handles the situation where the opposing party has not yet gathered the evidence needed to fight the motion. If declarations show that essential facts may exist but cannot yet be presented, the court can deny the motion, grant a continuance to allow further discovery, or make any other order it considers just.¹

The request can be made by ex parte motion at any time on or before the date the opposition is due. Courts look closely at diligence. A party that waited months to pursue discovery and only started requesting documents after being hit with a summary judgment motion will have a hard time getting more time. Courts weigh how long the case has been pending, whether the continuance could have been requested sooner, how close the trial date is, and whether the evidence sought is truly essential.

The Court’s Ruling

After the hearing, the court has to issue an order explaining its reasoning. On a grant, the court specifies why no triable issue of material fact exists and references the specific evidence. On a denial, the court identifies which material facts it found genuinely disputed and points to the evidence on both sides. The order can be written or oral, but it has to be recorded by a court reporter or in a written order. A bare “motion granted” is not enough under the statute.¹

What You Can Do After You Lose

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 other parts of the case remain active, and 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 that the order was entered. The same service extensions that apply to the 81-day notice period 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 also extend the filing period for good cause by up to 10 additional days.¹

Writ review is discretionary. The Court of Appeal is not required to hear the petition, and in practice grants review sparingly, so this path is far less reliable than a direct appeal.

Reconsideration

If the 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 on summary judgment and the strict “new facts” requirement for reconsideration, the practical point is the same: treat the first motion as the only one you will get, and build the record accordingly.
