Key Definitions
What is a Legal Exhibit?
A legal exhibit is a document, photograph, recording, or physical object presented as evidence in legal proceedings. Exhibits are marked with unique identifiers (e.g., "Exhibit A" or "Exhibit 1") for reference during testimony, in written briefs, and in court records. Under Federal Rules of Evidence 901(a), exhibits must be authenticated with "evidence sufficient to support a finding that the item is what the proponent claims it is."
Types of Exhibits
- Documentary Exhibits: Contracts, emails, invoices, medical records, photographs
- Demonstrative Exhibits: Charts, diagrams, timelines, animations created to illustrate testimony
- Summary Exhibits: Summaries of voluminous records per Federal Rule of Evidence 1006
- Rebuttal Exhibits: Evidence introduced specifically to counter opposing party's exhibits

What is an exhibit in legal proceedings?
A legal exhibit is a document, photograph, or other item introduced as evidence during court proceedings, depositions, or arbitration hearings. Exhibits must be marked with unique identifiers (such as "Exhibit A" or "Exhibit 1") for reference during testimony and in court records. Per Federal Rules of Evidence 901(a), exhibits must be authenticated by "evidence sufficient to support a finding that the item is what the proponent claims it is."
How should plaintiff exhibits be marked?
Plaintiff exhibits are typically marked with sequential numbers (Exhibit 1, Exhibit 2, Exhibit 3, etc.) in most U.S. jurisdictions. In California, per California Rules of Court 3.1110(c), plaintiffs use Arabic numerals. In Texas federal courts, plaintiffs use numbers with the prefix "PX" (PX-1, PX-2). Some jurisdictions also require color coding—for example, California courts traditionally use yellow stickers for plaintiff exhibits.
How should defendant exhibits be marked?
Defendant exhibits are typically marked with sequential letters (Exhibit A, Exhibit B, Exhibit C, etc.) in most U.S. jurisdictions. In California, per California Rules of Court 3.1110(c), defendants use letters. In Texas federal courts, defendants use numbers with the prefix "DX" (DX-1, DX-2). Some jurisdictions require color coding—California courts traditionally use blue stickers for defendant exhibits.
When must exhibits be exchanged before trial?
Exhibit exchange deadlines vary by jurisdiction. In California state courts, exhibits must be exchanged at least 30 days before trial per California Rules of Court 3.1302. In federal courts, Federal Rule of Civil Procedure 26(a)(3) requires exhibit lists to be disclosed at least 30 days before trial. Texas Rule of Civil Procedure 194.4 requires initial disclosures including exhibits. Local court rules may impose earlier deadlines, and pretrial orders often specify exact dates for exhibit exchange.
What are the federal rules for exhibit authentication?
Federal Rules of Evidence 901-903 govern exhibit authentication. Rule 901(a) requires the proponent to produce evidence sufficient to support a finding that the exhibit is what it claims to be. Rule 901(b) provides examples of authentication methods including testimony of a witness with knowledge (901(b)(1)), nonexpert opinion on handwriting (901(b)(2)), comparison by expert (901(b)(3)), and distinctive characteristics (901(b)(4)). Self-authenticating documents under Rule 902 include certified copies of public records, official publications, and acknowledged documents.
What is a summary exhibit under Federal Rule of Evidence 1006?
Federal Rule of Evidence 1006 allows parties to present summaries, charts, or calculations when the underlying writings, recordings, or photographs are too voluminous to be conveniently examined in court. The proponent must make the originals available for examination and copying by the opposing party. Summary exhibits are commonly used in complex litigation, financial fraud cases, and cases involving extensive documentary evidence. The summary must accurately reflect the underlying documents and cannot include argument or characterization.
