You've probably heard the phrase "showing up is half the battle." In the Southern District of New York (SDNY), showing up isn't just a metaphor—it’s a digital filing requirement that can make or break a case before a single witness even takes the stand.
A SDNY notice of appearance is, on its face, the most boring document in federal litigation. It is a one-page form. It tells the court, "Hey, I’m the lawyer for this person." But in the high-stakes world of Manhattan and White Plains federal courts, this little piece of paper carries a surprising amount of weight.
If you mess it up, you might miss a critical deadline because the court didn't have you on the notification list. Even worse, filing one at the wrong time could accidentally waive your right to argue that the court has no business hearing the case against you in the first place.
The Absolute Basics: What Is an SDNY Notice of Appearance?
Basically, it's a formal declaration by an attorney to the court and all other parties involved. It says that they are representing a specific client in a specific case.
Under the Local Rules of the Southern District of New York—specifically Local Civil Rule 1.4—every attorney appearing on behalf of a party must file this notice promptly. "Promptly" usually means on or before your first appearance in court or the first time you file any other document.
You've got 10 days after being appointed or retained to get this done, or before you walk into a hearing. Whichever comes first.
Who Actually Has to File One?
Most people assume every lawyer on a case needs to file one. They’re mostly right, but there’s a nuance here that catches people off guard.

If you are the lawyer who filed the very first document in the case—like the initial complaint or a notice of removal—the court considers you "in" already. You don't need a separate notice. You are deemed the counsel of record automatically.
However, if you're joining a case that’s already moving, or if you're "Pro Hac Vice" (an out-of-state lawyer allowed in for just this case), you’ve got work to do.
The Pro Hac Vice Connection
For lawyers not admitted to the New York bar but practicing in the SDNY for a specific matter, the process is a two-step dance. First, you file a motion to appear Pro Hac Vice. Once the judge signs that order, you aren't done. You must then immediately file your SDNY notice of appearance through the ECF (Electronic Case Filing) system.
Failure to do this second step is a classic "rookie" mistake. The judge might have said you're allowed to be there, but the computer system doesn't know to email you the updates yet.
The "Personal Jurisdiction" Trap
This is where things get genuinely dangerous. Honestly, this is the part most non-litigators (and even some lawyers) overlook.
In many cases, a defendant might want to argue that the SDNY doesn't have "personal jurisdiction" over them. Maybe they live in California and have never done business in New York.

Under New York law and certain interpretations within the Second Circuit, filing a formal SDNY notice of appearance can sometimes be viewed as a "voluntary appearance." This means you might accidentally be telling the court, "I recognize your authority over me."
If you’re planning to move to dismiss the case because the court lacks jurisdiction, you have to be incredibly careful. Often, lawyers will file a "Consent to E-Filing" instead of a formal notice of appearance to get access to the documents without technically "appearing" in the jurisdictional sense. It's a fine line.
How the Filing Process Actually Works in 2026
The SDNY doesn't do paper anymore unless you're a pro se litigant (representing yourself). Everything goes through the CM/ECF system.
When an attorney logs in to file the SDNY notice of appearance, they have to check a few specific boxes.
- The Association Box: You have to click to create an "association" with your client.
- The Notice Box: You ensure you’re opting in to receive "Notices of Electronic Filing" (NEFs).
- The Lead Attorney Box: If you’re the head honcho on the case, you mark yourself as lead.
Wait. There’s a catch. You cannot file a notice for someone else using your login. The ECF password and the name on the notice must match. If a firm wants five lawyers on the record, all five have to log in and file their own notices.

If you don't file, the court won't send you anything. You won't get the emails when the judge sets a trial date. You won't get the notification when the other side files a motion for summary judgment.
If you miss a hearing because you weren't on the electronic service list, the judge is likely to find you in default. In the SDNY, "I didn't get the email" is rarely a winning excuse if you never bothered to file your appearance.
Actionable Steps for Law Firms and Litigants
Don't treat this as a "later" task. It's a "now" task.
- Audit your ECF associations: Check the docket for every active case. If your name isn't there with a blue hyperlink, the court doesn't officially see you.
- Check for Pro Hac Vice completion: If you were granted admission months ago, verify that the actual notice of appearance was filed after the order was signed.
- Watch the Jurisdictional Clock: If you are a defendant, consult with a procedural expert before filing any document, including an appearance, to ensure you aren't waiving your defenses.
- Update your info: If you change firms or even just email addresses, you must file a "Notice of Change of Address" in every single pending case. The SDNY doesn't just "know" you moved because you updated your PACER profile.
The SDNY notice of appearance is the gateway to the litigation. It’s simple, but in the Southern District, the simple things are usually the ones that trip you up.
