FINRA Arbitration Exhibit Requirements
FINRA Customer Code Rule 12510 requires parties to exchange exhibits at least 20 calendar days before the hearing—the strictest deadline among major arbitral forums.

- FINRA Customer Code Rule 12510 requires exhibit exchange at least 20 calendar days before the hearing—the strictest major arbitral forum deadline in U.S. practice.
- FINRA Industry Code Rule 13510 imposes the same 20-day exchange requirement for disputes between industry members (broker-dealers and associated persons).
- Claimants in FINRA arbitration label exhibits C-1, C-2, C-3 (or C-001 for large productions); Respondents label exhibits R-1, R-2, R-3.
- Documents are exchanged through FINRA's DR Portal (Dispute Resolution Portal), FINRA's online case management system for all arbitration proceedings.
- FINRA panels routinely exclude exhibits not exchanged by the 20-day deadline; exclusion is more consistently applied than in AAA or JAMS proceedings.
- FINRA arbitration is specific to securities and brokerage industry disputes; standard brokerage account agreements require FINRA arbitration for investor-broker disputes.
- The Federal Rules of Evidence do not apply in FINRA arbitration; the panel applies the FINRA Code of Arbitration Procedure and has broad discretion over admissibility.
- FINRA arbitration cannot be waived by broker-dealer firms in pre-dispute agreements for customer disputes—arbitration is mandatory under FINRA rules.
FINRA Exhibit Key Requirements
20-Day Exchange Deadline
Rule 12510 (Customer) and Rule 13510 (Industry) both require exchange at least 20 calendar days before the hearing. This deadline is strictly enforced.
C/R Prefix Labels
Claimants use C-1, C-2, C-3. Respondents use R-1, R-2, R-3. Zero-padded numbering (C-001) recommended for large securities document productions.
FINRA DR Portal
All exhibits submitted through FINRA's Dispute Resolution Portal. Obtain portal access credentials from the FINRA case administrator at the outset of the proceeding.
Exclusion Risk
Exhibits not exchanged by the 20-day deadline may be excluded entirely. FINRA panels apply this sanction more consistently than AAA or JAMS panels.
The 20-Day Deadline Is Strict — Plan Accordingly
Unlike AAA and JAMS where the arbitrator can adjust exchange deadlines, FINRA Rule 12510's 20-day requirement is a fixed rule in the Code of Arbitration Procedure. Missing this deadline risks exhibit exclusion that can be case-dispositive in securities disputes where documentary evidence—account statements, trade confirmations, emails—is central to the claim. Build your exhibit preparation timeline to complete exchange at least 22-25 days before the hearing as a buffer against last-minute delays.

Frequently Asked Questions
What is the FINRA exhibit exchange deadline under Rule 12510?
FINRA Customer Code Rule 12510 requires all parties to exchange copies of documents they intend to present as exhibits at least 20 calendar days before the arbitration hearing. This is one of the strictest exchange deadlines in arbitration practice—stricter than AAA's 5-day default and JAMS's arbitrator-set schedule. FINRA arbitration panels routinely exclude exhibits that were not exchanged by the 20-day deadline, and FINRA's Office of Dispute Resolution does not routinely grant extensions. The same 20-day requirement applies to industry disputes under FINRA Industry Code Rule 13510.
How are exhibits labeled in FINRA arbitration?
In FINRA arbitration, Claimants label their exhibits C-1, C-2, C-3 and Respondents label their exhibits R-1, R-2, R-3. For large document productions common in securities disputes—account statements, trade confirmations, correspondence—zero-padded numbering (C-001, C-002) is recommended so files sort correctly in the FINRA DR Portal and in the arbitration panel's exhibit set. If multiple claimants or respondents are present, the panel may direct a coordinated numbering convention at the preliminary hearing.
What happens if a party fails to exchange exhibits by the FINRA 20-day deadline?
If a party fails to exchange exhibits by the FINRA Rule 12510 20-day deadline, the arbitration panel may exclude those exhibits from the hearing entirely. Exclusion is the most common sanction and is routinely applied by FINRA panels. A party seeking to introduce a late exhibit must typically make a motion explaining the cause of the late disclosure; the panel has discretion to grant or deny the motion. Because FINRA cases often turn on documentary evidence such as account statements and trade confirmations, exhibit exclusion can be case-dispositive. Build your exhibit preparation timeline to ensure exchange is completed at least 22-25 days before the hearing as a buffer.
What is the FINRA DR Portal and how are exhibits submitted?
FINRA's DR Portal (Dispute Resolution Portal) is FINRA's online case management system for all arbitration and mediation proceedings. Parties submit exhibits, briefs, and other case documents through the DR Portal. Documents are uploaded in PDF format and are shared with the panel and all parties. For hearing purposes, parties should also provide physical or electronic exhibit sets as directed by the panel. Confirm submission format requirements with the FINRA case administrator at the outset of the proceeding, as practices may vary by hearing location and panel preference.
What types of disputes does FINRA arbitration cover?
FINRA arbitration is specific to disputes arising from securities and brokerage industry relationships. FINRA Customer Code (Rule 12000 series) governs disputes between investors and their broker-dealers or associated persons—including claims of unsuitable investment recommendations, churning, unauthorized trading, failure to supervise, and fraud. FINRA Industry Code (Rule 13000 series) governs disputes between industry members (broker-dealers and their associated persons). Standard brokerage account agreements require customers to resolve disputes through FINRA arbitration, making it the primary dispute resolution forum for retail securities claims in the United States.
How does FINRA arbitration compare to AAA and JAMS for exhibit requirements?
FINRA's 20-day exchange deadline under Rule 12510 is the strictest among the major arbitral forums: AAA Commercial Rule R-22 establishes a default 5-day deadline, and JAMS Rule 22(e) gives the arbitrator discretion with no fixed default. All three forums use the Claimant (C-1) and Respondent (R-1) prefix convention. FINRA is unique in that its exclusion sanction for late exchange is more consistently applied than in AAA or JAMS proceedings. FINRA also uses its own DR Portal rather than AAA's AMP platform or JAMS's proprietary portal. FINRA's scope is narrow—securities industry disputes only—while AAA and JAMS handle commercial disputes across all industries.
