Key facts

  • Address mail to Clerk of Court, United States District Court for the Middle District of Louisiana, Russell B. Long Federal Building and United States Courthouse, 777 Florida Street, Suite 139, Baton Rouge, LA 70801.
  • Civil and criminal filing is almost entirely electronic here too. Attorneys and other registered users must file through CM/ECF — mail is for pro se litigants without ECF access, required paper copies, and correspondence that isn't a filing.
  • Always put the case/docket number (e.g., "No. 1:24-cv-01234") on every page and on the outside of the envelope — without it, the clerk's office cannot route your documents.
  • This is the trial-level federal court for the Middle District of Louisiana in Louisiana — some states have more than one federal district, so confirm this is the right one before mailing anything.
  • A document is filed when the clerk receives and dockets it, not when you mail it. Post well ahead of any deadline, and consider a mail method with tracking for anything time-sensitive.
  • PostPal prints your documents and hands them to USPS the next business day for $5 — no printer, envelope, or trip to the post office, with your return address printed for the reply.

How to send your letter

  1. 1

    Confirm you need to mail it, not e-file it

    Represented parties and most filers must use CM/ECF. Mail is for pro se litigants without ECF access, or for paper copies this district's local rules still require alongside an e-filed document — check the clerk's office before mailing a filing with a deadline.

  2. 2

    Confirm this is the right district

    Louisiana may have more than one federal district — this is the Middle District of Louisiana. Filing in the wrong district can get your case transferred or dismissed.

  3. 3

    Put the case/docket number on everything

    Every page and the outside of the envelope should show your case number if you have one. New pro se filings need a completed civil or criminal cover sheet — check the court's forms page.

  4. 4

    Send it without printing anything

    Write or upload your documents in PostPal with the Middle District of Louisiana clerk's address prefilled, and we print and mail them via USPS the next business day for $5.

Can I file a case or documents by mail?

When is a mailed document considered filed?
