A certificate of compliance is a short signed statement attached to a court filing that confirms the document follows the applicable rules on word count, formatting, or related procedural requirements. Federal appellate courts use the most standardized version, Form 6 in the Appendix to the Federal Rules of Appellate Procedure, but trial courts at every level use similar certificates for briefs, motions, and discovery papers. The certificate itself is usually one page, but getting it wrong can get your filing bounced by the clerk before a judge ever reads it.
When You Need One
Appellate Briefs and Motions
The clearest requirement is in federal appellate practice. Under Federal Rule of Appellate Procedure 32(g), any brief filed under a type-volume limit must include a certificate from the attorney (or an unrepresented party) stating the document’s word count or line count and confirming it falls within the allowed limit.1Legal Information Institute. Rule 32. Form of Briefs, Appendices, and Other Papers A principal brief cannot exceed 13,000 words; a reply brief is capped at 6,500.2U.S. Court of Appeals for the Second Circuit. FRAP 32. Form of Briefs, Appendices, and Other Papers Cross-appeal briefs have their own limits under Rule 28.1.3Legal Information Institute. Rule 28.1 Cross-Appeals
The requirement isn’t limited to briefs. Petitions for rehearing, amicus briefs, and certain motions also need a certificate when they invoke a type-volume limit instead of a page limit. If your filing exceeds the page cap and uses the word-count alternative, the certificate is what proves it still qualifies.
Discovery in Trial Courts
In federal trial courts, the certificate concept runs through Rule 26(g) of the Federal Rules of Civil Procedure. Every discovery disclosure, request, response, and objection must be signed by an attorney or unrepresented party, and that signature itself certifies that the signer made a reasonable inquiry, that the disclosure is complete and correct, and that the response is consistent with the rules and not interposed to harass or delay.4United States District Court for the Northern District of Illinois. Rule 26 of the Federal Rules of Civil Procedure Some courts also require a separate certificate confirming compliance with scheduling-order deadlines.
A Note on Certificates of Service
A certificate of compliance is not the same thing as a certificate of service. The service version confirms the filing reached every party entitled to notice. Under Rule 5 of the Federal Rules of Civil Procedure, no certificate of service is needed when a document is served through the court’s electronic filing system, since the system itself generates the notification. When service happens by mail, hand-delivery, or email with written consent, a certificate of service must be filed with the document or shortly after.5Legal Information Institute. Rule 5. Serving and Filing Pleadings and Other Papers Many filings need both certificates.
What Goes in the Certificate
Every certificate opens with the case caption (party names exactly as they appear in the original complaint), the case number, and the court division. Clerks reject filings for caption errors as readily as for substantive ones, which can mean a missed deadline with no do-over.
The body of the certificate identifies the specific rule or court order you’re certifying compliance with and gives the relevant measurement. For a brief, that’s the word count or line count. For formatting, it’s the typeface and point size. Federal Form 6, in the Appendix of Forms to the Federal Rules of Appellate Procedure, is a solid template even in courts that don’t require it. The form asks for two things:6U.S. Court of Appeals for the Second Circuit. Federal Rules of Appellate Procedure Form 6. Certificate of Compliance With Type-Volume Limit
- Type-volume compliance: the specific rule citation (for example, Fed. R. App. P. 32(a)(7)(B)) and the document’s word count or line count.
- Typeface and type-style compliance: the word-processing program used, the font name and size, and whether the typeface is proportionally spaced or monospaced.
It closes with a signature line, the attorney’s name, the party represented, and the date. If the court has its own prescribed form, use that version. The Federal Circuit, for example, requires its own Form 19 rather than the generic Form 6.
Counting Words and Checking Formatting
You can rely on your word processor’s built-in word count, and the federal rules explicitly allow it.2U.S. Court of Appeals for the Second Circuit. FRAP 32. Form of Briefs, Appendices, and Other Papers What matters is counting the right portions. Rule 32(f) excludes the cover page, disclosure statement, table of contents, table of citations, statement regarding oral argument, any statutory addendum, the certificate of compliance itself, the signature block, and the proof of service.1Legal Information Institute. Rule 32. Form of Briefs, Appendices, and Other Papers Footnotes do count. Leaving footnotes out of the tally is one of the most common errors appellate clerks flag.7U.S. Court of Appeals for the Federal Circuit. Common Filing Errors
Federal appellate rules set the baseline formatting standards for font, size, margins, and spacing. State courts and local federal rules often impose different requirements, so always check the specific rules for the court where you’re filing. The certificate needs to reflect that court’s standards, not a generic default.
Signing and Filing
The certificate must be signed by the attorney of record or, for a self-represented party, by the party. In electronic filing, this typically takes the form of a typed “/s/” followed by the filer’s full name; the court’s system treats a filing made through an authenticated account as a signature.5Legal Information Institute. Rule 5. Serving and Filing Pleadings and Other Papers A wet-ink signature is standard for paper filings.
The certificate is attached as the last page of the brief or filing it accompanies, not filed on its own. For e-filing, upload the brief and certificate together as a single PDF. Most courts require text-searchable PDFs, so export directly from your word processor rather than scanning a printout.
Mistakes That Get Filings Rejected
Clerks see the same errors over and over, and any of them can draw a deficiency notice:7U.S. Court of Appeals for the Federal Circuit. Common Filing Errors
- Omitting the certificate when the brief relies on the word-count alternative to the page cap.
- Certifying a word count that doesn’t match the actual count, often because footnotes were excluded.
- Citing the wrong rule, such as Rule 32(a)(7)(B) when the filing is actually governed by Rule 28.1(e)(2) for cross-appeals or by a local rule with a different cap.
- A caption that doesn’t match the docket: misspelled parties, wrong case number, or wrong division.
- Using the generic Form 6 in a court that requires its own version.
If the Certificate Is Defective or False
Procedural Sanctions
In discovery, a missing or improper certification can prompt a motion to compel under Rule 37. If the court grants it, the rule requires the non-complying party or attorney to pay the other side’s reasonable expenses, including attorney’s fees, unless the failure was substantially justified. If noncompliance continues after a court order, sanctions escalate: the court can strike pleadings, bar evidence, stay proceedings, dismiss the case, or enter default judgment.8Legal Information Institute. Rule 37. Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
Rule 11 Sanctions
A certificate of compliance carries the same weight as any other signed filing under Rule 11 of the Federal Rules of Civil Procedure. If the court finds a false representation (certifying 12,500 words on a brief that actually runs 14,000, for example), it can sanction the attorney, the firm, or the party. Rule 11 sanctions must be limited to what is needed to deter the conduct and can include nonmonetary directives, a penalty paid into court, or reimbursement of the opposing party’s fees.9Legal Information Institute.

Criminal Exposure
Intentionally lying in a certificate can cross into criminal territory. Federal perjury carries a maximum sentence of five years in prison.10Office of the Law Revision Counsel. 18 U.S. Code 1621 – Perjury Generally The related statute on false statements to a court or government body carries the same five-year maximum.11Office of the Law Revision Counsel. 18 U.S. Code 1001 – Statements or Entries Generally Prosecutions over a certificate of compliance are rare, but the exposure is real, and judges take a dim view of attorneys who treat word counts as flexible.
