Sequential Labeling
Numbering or lettering exhibits in consecutive order (1, 2, 3... or A, B, C...) rather than by custom labels.
What You Need to Know
Sequential labeling assigns consecutive numbers or letters to exhibits following court conventions—plaintiffs use 1, 2, 3, defendants use A, B, C per California Rules of Court 3.1110(c) and similar state court rules. Sequential systems prevent duplicate exhibit labels, simplify record-keeping, and make it easy to identify missing exhibits in the sequence. Some attorneys leave gaps (1, 2, 5, 10, 15) to allow adding exhibits later without renumbering everything. Federal courts allow parties to choose their own labeling systems, though sequential numbering remains standard. Automated exhibit stamping software can apply sequential labels to hundreds of documents in minutes, ensuring consistency and eliminating manual numbering errors.

Frequently Asked Questions
Should I use sequential numbering or custom exhibit labels?
Use sequential numbering unless court rules require otherwise or you have a specific organizational need. Benefits of sequential numbering: (1) prevents duplicate labels—every exhibit gets a unique number, (2) easy to spot missing exhibits in the sequence, (3) automated stamping software can auto-increment numbers, (4) witnesses and judges can reference exhibits by simple numbers during testimony. Custom labels (like "Medical Bill - Dr. Smith") are descriptive but risk duplicates and don't work well with court tracking systems. Some attorneys combine both: sequential numbers for official marking (Exhibit 1, 2, 3) plus descriptive file names in their case management system.
What if I need to add exhibits after sequential numbering is complete?
You have three options: (1) use the next available number in sequence (if you marked Exhibits 1-50, add new exhibits as 51, 52, 53), (2) use sub-labels like "Exhibit 25A" or "Exhibit 25-1" to insert exhibits between existing numbers, or (3) leave intentional gaps when originally numbering (1, 2, 5, 10, 15, 20) so you can fill in (3, 4, 6, 7, 8, 9) later. Option 1 is simplest but may disrupt chronological or topical organization. Option 2 maintains order but creates complex labels. Option 3 requires planning ahead. Avoid renumbering all exhibits after exchange with opposing counsel—this creates confusion and may violate local rules requiring consistency between exchanged and trial exhibits.
Do deposition exhibits and trial exhibits use different numbering sequences?
Yes, they typically use separate sequential numbering systems. Deposition exhibits are marked "Deposition Exhibit 1, 2, 3" during the deposition and attached to that deposition transcript. The same documents may later be re-marked as "Trial Exhibit 15, 16, 17" following your trial exhibit sequence. This separation prevents conflicts when multiple depositions each have "Exhibit 1" or when deposition exhibits aren't all used at trial. Some attorneys reserve trial exhibit numbers for key documents (1-50) and use higher numbers (100+) for less critical exhibits, allowing strategic numbering. Always cite both when referencing deposition testimony at trial: "Deposition of John Smith, page 42, lines 5-10, referring to Deposition Exhibit 7, now marked as Trial Exhibit 23."
When It's Used
Simplifies exhibit management and prevents duplicate labels
Example
"Auto-numbering 50 plaintiff exhibits as 1 through 50 instead of manually assigning each number."
