To file a cross-appeal in federal court, submit a notice of cross-appeal to the district court clerk within 14 days after the first party files its notice of appeal, or within the time otherwise allowed under Federal Rule of Appellate Procedure 4(a), whichever is later.1Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right—When Taken The notice identifies you as the cross-appealing party, specifies which parts of the judgment you want reviewed, and must be served on every other party. A docketing fee of $500 applies.2Legal Information Institute. Federal Rules of Appellate Procedure Rule 39 – Costs The window is short and the procedural rules are strict, so the first question to settle is whether a cross-appeal is the right tool at all.
Decide Whether You Actually Need One
The test is simple: do you want the appellate court to change the judgment? If the other side appeals and you are satisfied with what the trial court gave you, a cross-appeal is unnecessary. You can defend a favorable result on alternative grounds without filing anything.
Say you won at trial on a negligence theory but the court rejected your breach-of-contract argument. If the other side appeals the negligence finding, you can argue in your appellee’s brief that the contract claim provides an independent basis to affirm. That doesn’t require a cross-appeal, because you’re defending the bottom-line result rather than asking for something the trial court didn’t give you.
A cross-appeal becomes necessary when you want more. If the jury awarded $100,000 but you believe the correct figure was $250,000, defending the verdict isn’t enough; without a cross-appeal, the appellate court lacks power to increase the award. The same logic applies when the trial court ruled against you on one of several claims but you still won overall. Those adverse rulings stand unless you cross-appeal them.
You also need standing as an “aggrieved party.” A litigant who received everything requested at trial has no basis to cross-appeal. You can be a technical winner and still be aggrieved, though, if the court denied part of your requested relief or decided a legal issue against you that could matter later.
The 14-Day Deadline
Rule 4(a)(3) controls. Once the first notice of appeal is filed, you have 14 days from that filing to submit your cross-appeal, or the full time otherwise allowed under Rule 4(a), whichever is later.1Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right—When Taken In most civil cases the baseline appeal period is 30 days from entry of judgment. When the federal government is a party, it is 60 days.
A worked example makes the “whichever is later” piece clearer. If judgment is entered on January 1 and the opposing party files its notice of appeal on January 20, your cross-appeal is due February 3. But if the opposing party files on January 2, the 14-day window closes January 16, while the standard 30-day period runs through January 31. You get until January 31, because the rule gives you the later of the two.
The entry date on the court’s electronic docket controls the baseline period. Check it there rather than relying on when the order arrived in your inbox.
If You Miss the Deadline
Rule 4(a)(5) provides a narrow extension path. You can ask the district court for more time, but only on a showing of “excusable neglect or good cause,” and the motion must be filed no later than 30 days after the original deadline expired. Even if granted, the extension cannot exceed 30 days past the original deadline or 14 days after the court enters the order granting the motion, whichever is later.1Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right—When Taken Courts treat these extensions as exceptional. Forgetting the deadline or miscalculating the date rarely qualifies.
What Goes in the Notice
The notice of cross-appeal itself is a short document, but precision matters. Include the full case name, the trial court docket number, and the exact entry date of the final judgment or order being challenged.
Identify yourself as the cross-appealing party and specify which parts of the judgment you are challenging. Be explicit. Cite the paragraph numbers or particular rulings from the original order that you want the appellate court to review. Generic language like “all adverse rulings” may not preserve specific issues for appellate review, because the court’s jurisdiction over your cross-appeal reaches only the matters you designate.
Filing, Fees, and Service
Most federal courts require electronic filing through the CM/ECF system; physical delivery to the clerk’s office is available where local rules permit it.3United States Courts. Electronic Filing (CM/ECF) The federal appellate docketing fee is $500, set by the Judicial Conference under 28 U.S.C. § 1913.2Legal Information Institute. Federal Rules of Appellate Procedure Rule 39 – Costs Additional district court filing fees can push the total above $600. If paying is a hardship, you can apply for a fee waiver.
You must serve the notice on every other party. If service happens outside the court’s electronic filing system, include proof of service with your filing. That proof must state the date and method of service, the names of everyone served, and their addresses or electronic contact information.4Legal Information Institute. Federal Rules of Appellate Procedure Rule 25 – Filing and Service The clerk’s office issues a receipt or electronic confirmation once the filing is accepted.
What Changes After You File
Filing a cross-appeal reshapes the briefing. Instead of the normal three-brief sequence, there are four, and the labels reflect each party’s dual role.5Office of the Law Revision Counsel. 28 USC App, Federal Rules of Appellate Procedure Rule 28.1 – Cross-Appeals The party who filed first is the appellant; the cross-appealing party is the appellee. If both notices were filed the same day, the plaintiff below is treated as the appellant.
The briefs proceed in this order:
- Appellant’s principal brief, arguing the issues raised in the original appeal.
- Appellee’s principal and response brief, a combined document responding to the appellant’s arguments and presenting the cross-appeal arguments.
- Appellant’s response and reply brief, responding to the cross-appeal and replying on the original appeal.
- Appellee’s reply brief, limited strictly to issues raised in the cross-appeal.
No additional briefs are allowed unless the court grants leave. Rule 28.1(e) sets the following limits:6Legal Information Institute. Federal Rules of Appellate Procedure Rule 28.1 – Cross-Appeals
- Appellant’s principal brief: 30 pages or 13,000 words.
- Appellee’s principal and response brief: 35 pages or 15,300 words.
- Appellant’s response and reply brief: 30 pages or 13,000 words.
- Appellee’s reply brief: 15 pages or 6,500 words.
Federal rules also prescribe cover colors: blue for the appellant’s principal brief, red for the appellee’s principal and response brief, yellow for the appellant’s response and reply brief, and gray for the appellee’s reply brief.5Office of the Law Revision Counsel. 28 USC App, Federal Rules of Appellate Procedure Rule 28.1 – Cross-Appeals
Oral argument happens on a single date covering both the appeal and the cross-appeal, not separately.7Legal Information Institute. Federal Rules of Appellate Procedure Rule 34 – Oral Argument Rule 28.1(b) decides who argues first based on who filed the initial notice. Time is allotted to each side rather than to each individual party, so parties with aligned interests share one time block and are expected not to repeat points.
Stays and Bonds
If your cross-appeal challenges a money judgment or an injunction, you may need to seek a stay of the trial court’s order while the appeal proceeds. Rule 8 requires you to ask the district court first, and typically to post a bond or other security protecting the opposing party during the delay.8Legal Information Institute. Federal Rules of Appellate Procedure Rule 8 – Stay or Injunction Pending Appeal If the district court denies the request, you can move in the court of appeals, which has independent authority to grant a stay and set its own security requirements.
Any entity providing security on a stay submits to the district court’s jurisdiction, and liability on the bond can be enforced there by motion rather than a new lawsuit. The bond amount usually reflects the full judgment plus estimated interest and costs through the appeal.
If the Other Side Walks Away
A cross-appeal needs an initial appeal to come into existence, but once filed and docketed it stands on its own. If the original appellant voluntarily dismisses under Rule 42, the cross-appeal typically remains pending, because the cross-appellant has independently invoked the appellate court’s jurisdiction.9Legal Information Institute. Federal Rules of Appellate Procedure Rule 42 – Voluntary Dismissal The appellate court can decide your cross-appeal issues even after the original appeal is gone.
The original appellant cannot escape the cross-appeal by walking away. To end the appellate proceedings entirely, both sides need a signed stipulation of dismissal covering the appeal and the cross-appeal. Dismissing only one leaves the other intact.
