Trial Exhibits: From Stamped Production to Courtroom-Ready
How to prepare a trial exhibit set — numbering schemes, the AO-187, the combined binder, and the moves that keep you out of trouble at the pretrial conference.
A trial exhibit set has to do three jobs at once: identify each piece of evidence unambiguously, match the exhibit list and the AO-187 exactly, and survive last-minute reordering without collapsing into a renumbering nightmare. Most paralegals build it by hand in Acrobat the week of trial. Here's the workflow that holds together when the judge calls a status conference at 4:50 PM and asks for the new exhibit list by morning.
What counts as a "trial exhibit"
A trial exhibit is a discrete piece of evidence that a party intends to introduce at trial. Each one gets a single number or letter — page two of Ex. 14 is still Ex. 14. The exhibit may have come into the case earlier (as a deposition exhibit, a document production page, or a pleading attachment), but at trial it gets a new identity tied to the trial sequence.
Trial exhibits typically carry three layers of marking: the exhibit sticker on the first page, Bates numbers across every page (often the same Bates numbers from the underlying production), and any confidentiality endorsement that survives from the protective order.
The lifecycle
1. Build the list
Start with a working spreadsheet or document of every exhibit you're going to offer. Each row gets a tentative number, a short neutral description, the witness who'll authenticate it, and the underlying Bates range (or source). Co-counsel reviews and reorders here, before any stamping happens — reordering is cheap on a spreadsheet and expensive after stamps are applied.
2. Apply the stamps
With the list locked, stamp the production: exhibit sticker on the first page using your court's convention (see sticker placement rules), Bates numbers carried over from the production, and any confidentiality endorsement. The numbering scheme depends on the court — see federal numbering conventions for the six systems federal districts actually use.
3. Generate the AO-187
The federal courts' AO-187 (or the local equivalent) lists every exhibit a party intends to introduce. The columns must match the stamps exactly. Generating the form from the same source as the stamps — one source of truth — eliminates the typos that otherwise accumulate from re-keying. See the AO-187 guide.
4. Build the combined binder
A trial-ready binder is a single hyperlinked PDF with a cover page, table of contents, bookmarks, continuous Bates numbers, and first-page exhibit stamps. See the trial binders guide for the format that works in every federal courtroom.
5. Exchange + file
Exchange with opposing counsel and file with the court per the local exchange deadline (which varies from 48 hours to 35 days — see pretrial exchange deadlines). Late additions are heavily disfavored.
Common mistakes
- Stamps don't match the AO-187. Ex. 14 is described as "Email 6/15" on the form but the actual stamped exhibit shows the email is dated 6/16. First ten minutes of direct evaporates.
- Numbering convention doesn't match the district. Stamping P-1, P-2 in a court that uses Plaintiff Ex. 1, Ex. 2 — the bench will correct you, and you owe a corrected set the same day.
- Sticker placement competes with the Bates number. Both in the bottom-right corner, neither legible. The fix is to put the sticker upper-right or use a different corner per local rule.
- No combined binder. The judge asks for the exhibit binder; you hand over a folder of 50 PDFs. A single hyperlinked PDF is the courtroom-ready format.
How Stampify handles trial exhibits
Drop the production into Stampify, set the numbering scheme (matching your court's convention), the sticker placement, and the confidentiality endorsement if applicable. The output:
- Stamped PDFs of every exhibit, individually downloadable.
- An AO-187 generated from the same exhibit list.
- A combined trial binder with hyperlinked TOC and bookmarks.
- A CSV load file for any e-discovery handoff.
Reordering exhibits is a drag-and-drop. Every artifact regenerates with the new sequence, no manual rework. Stamp smarter— start your trial exhibit set now.
