C.D. Cal. Local Rules: Motions, Discovery, and E-Filing

The local rules of the U.S. District Court for the Central District of California govern the mechanics of every civil case in the district, from how your caption is formatted to when your opposition brief is due. The court revises these C.D. Cal. local rules twice a year, on June 1 and December 1, and Chapter I (civil) was last amended on December 1, 2025.¹ The only reliable version is the current PDF on cacd.uscourts.gov under the “Local Rules” tab; older printed copies and third-party summaries frequently lag behind revisions.

Document Formatting Under Rule 11

Local Rule 11 sets appearance requirements that are stricter than what many practitioners expect coming from other districts. Typeface must be no smaller than 14 points. Margins are at least one inch on all sides. The left margin carries line numbering from 1 through 28. Text is double-spaced, though long block quotations and footnotes may be single-spaced.¹

The first page needs a specific header block. Starting at line one on the top left, list the attorney’s name, bar number, firm, address, phone, and email. Pro se filers put their own contact information in the same place. The court name is centered around line eight, and the case caption with party names, case number, and the assigned judge’s initials fills the space below.

Local Rule 11-6 imposes page limits on briefs and memoranda of points and authorities. Local Rule 11-8 requires a Table of Contents and Table of Authorities for longer filings, with accurate page references for every heading and every citation. A noncompliant document can be stricken or ordered refiled.¹

Electronic Filing Through CM/ECF

Local Rule 5-4.1 requires civil documents to be filed electronically through CM/ECF, with limited exceptions.² A filing is timely if completed before midnight Pacific Time on the due date. After submission, CM/ECF generates a Notice of Electronic Filing with a timestamp; save it. The system also serves all other counsel of record automatically, so separate mail service is usually unnecessary.

Who Can Skip E-Filing

Local Rule 5-4.2 exempts pro se litigants from the e-filing mandate. They can file in paper at the Clerk’s Office or use the court’s Electronic Document Submission System. Attorneys not registered on CM/ECF can also seek a limited exemption for good cause, but it lasts one calendar year and must be renewed.²

Some documents cannot be filed electronically regardless of who submits them: physical exhibits that are not paper, oversized paper exhibits that cannot be scanned to PDF, and certain sealed materials. These get lodged in paper with the Clerk or submitted at trial or hearing under Local Rules 79-3 or 79-4.

Motion Practice

Meet and Confer First

Local Rule 7-3 requires the moving party to contact the opposing side and make a genuine effort to resolve the dispute before filing most motions. Judges in this district treat this as substantive, not clerical. A motion filed without a proper meet-and-confer declaration will often be denied or taken off calendar.

Opposition and Reply Deadlines

Under Local Rules 7-9 and 7-10, an opposition must be filed and served at least 21 days before the hearing, and a reply is due at least 14 days before the hearing. A late opposition can be treated as consent to the motion; a late reply may not be considered at all. Individual judges sometimes set different deadlines in their standing orders, and those control.

Reconsideration

Local Rule 7-18 gives you 14 days after the challenged order to move for reconsideration, absent good cause for a longer delay.² The bar is high: newly discovered facts, a change in controlling law, or clear error in the original ruling.

Discovery Disputes Use a Joint Stipulation

The Central District handles discovery disagreements through a joint stipulation, not the usual motion-and-opposition sequence. Both sides draft a single document laying out each party’s position on the disputed issue. Under Local Rule 37-2.3, each party may then file a supplemental memorandum no later than 14 days before the hearing.² Meet-and-confer is required before any discovery motion, and many judges expect several informal attempts before they will hear a motion to compel.

ADR Selection at the Start of the Case

Unless the trial judge grants an exemption, every civil case must participate in one of three ADR options: a settlement conference with the assigned district judge or a magistrate judge, mediation with a neutral from the Court Mediation Panel, or private mediation.³ Local Rule 16-15.2 requires the parties to file a joint ADR Procedure Selection form with their Rule 26(f) report, so ADR needs to be on the agenda in the first conference with opposing counsel.²

Related Cases and Judge Shopping

Local Rule 83-1.3.1 requires the parties to identify related cases whenever two or more civil actions arise from the same events, involve substantially similar legal questions, or would duplicate effort if handled by different judges. A Notice of Related Cases must be filed when the new case is filed, or as soon as the relationship becomes apparent, and it must explain the factual connection.²

The court also forbids dismissing a case and refiling it to draw a different judge. Local Rule 83-1.2.1 bars the practice outright, and Local Rule 83-1.2.2 assigns any refiled case involving essentially the same claims and parties back to the original judge. Counsel must disclose the prior filing in the Civil Cover Sheet and in a Notice of Related Cases.²

Filing Under Seal

Sealing is not automatic. An application for leave to file under seal must be filed electronically along with the sealed documents themselves, unless the entire case is already sealed. Local Rules 79-5, 79-6, and 79-7 spell out the requirements.⁴

Once a sealing order issues, each sealed document must carry a caption line reading “FILED UNDER SEAL PURSUANT TO ORDER OF THE COURT DATED ___.” For documents exempt from e-filing that must go in paper, the original and the judge’s copy travel in separate sealed envelopes, each with a copy of the title page attached to the front, along with a PDF on a CD. Many judges participate in a pilot program allowing sealed documents to be submitted by email, so check the assigned judge’s standing orders first.⁴

Judge Standing Orders and Chambers Copies

The local rules set the baseline; each judge layers a standing order on top. Those judge-specific directives frequently change motion days, briefing schedules, courtesy copy requirements, and courtroom procedure. They live on the court’s website under “Judges’ Procedures and Schedules.” Not checking them before the first filing in a case is one of the most common avoidable mistakes in this district.

Local Rule 5-4.5 is a standing trap. Unless the assigned judge orders otherwise, a paper chambers copy of every electronically filed document in a civil case must be delivered to the Clerk’s Office for that judge by noon on the day after filing. The chambers copy is marked “Chambers Copy” on the title page and follows the same formatting rules as the filed original.² Some judges waive chambers copies. Others accept them electronically. Others want them tabbed and bound. When the standing order conflicts with the general rule, the standing order wins.

Rules for Pro Se Litigants

Self-represented parties are held to the same local rules as attorneys, with a few practical accommodations. Local Rule 1-3 confirms the rules apply to everyone. Local Rule 5-4.2 exempts pro se litigants from mandatory e-filing, allowing paper filings at the Clerk’s Office or submissions through the Electronic Document Submission System. Local Rule 16-12 exempts certain cases involving pro se litigants who are in custody and are not attorneys from scheduling orders and pretrial conferences. For everyone else, the same deadlines, formatting, and meet-and-confer duties apply.²

Sanctions for Violations

Local Rule 83-7 authorizes the court to enforce the local rules against parties and their attorneys. The court can impose monetary sanctions where the noncompliant conduct was willful, grossly negligent, or reckless. Where the conduct amounts to bad faith or willful disobedience of a court order, the violator can be ordered to pay the opposing side’s costs and attorney fees. The court also retains discretion to impose any other sanction it deems appropriate for conduct meeting either threshold.²

In practice, most formatting or filing errors are handled by striking the document and ordering a corrected refiling. Repeated violations, or violations that waste the court’s time or prejudice the other side, move quickly toward monetary penalties.
