If a FINRA arbitration is decided mostly on written submissions, the case often looks very different from the version many people picture when they hear the word “arbitration.” There may be no live hearing at all. Instead, one arbitrator usually reviews the statement of claim, answer, supporting documents, written arguments, and any limited discovery exchanged by the parties, then issues an award based on that paper record. Under FINRA’s simplified arbitration rules, that framework generally applies to customer disputes involving $50,000 or less, exclusive of interest and expenses, unless the customer asks for a hearing. FINRA also notes that these “paper” decisions tend to move faster than regular hearing cases. FINRA Rule 12800, FINRA’s simplified arbitration overview, and FINRA’s 2025 dispute resolution statistics
That shift can change almost everything: how evidence is presented, how credibility is evaluated, how discovery plays out, and how much depends on the clarity of the written story. For investors trying to understand the bigger structure, it may help to start with this overview of how simplified FINRA arbitration works in smaller cases. In this post, you’ll learn what changes when the arbitrator is mostly reading instead of listening.

In FINRA simplified arbitration, a case can be decided on the papers when no hearing is requested. FINRA describes these as “paper” cases because the arbitrator decides the dispute based solely on the parties’ pleadings and other written submissions. If the customer does not expressly choose a regular hearing or a special proceeding, the matter is generally treated as a paper case by default. FINRA’s simplified arbitration overview
In practical terms, the written record often includes:
That may sound streamlined, and sometimes it is. But it also means the written presentation carries much more weight than in a hearing-driven case. A fact that might come alive through testimony in a live proceeding can look thin or incomplete if it is not clearly documented.
FINRA’s simplified arbitration rule is aimed at disputes involving $50,000 or less, exclusive of interest and expenses. The idea is to provide a more efficient forum for lower-dollar claims while still keeping the arbitration process available to investors and firms. These cases are generally decided by a single public arbitrator unless the parties agree otherwise in writing. FINRA Rule 12800
FINRA’s own timeline data helps explain the appeal of this format. In 2025, FINRA reported average turnaround times of 5.0 months for paper decisions, compared with 6.8 months for special proceeding decisions and 15.9 months for regular hearing decisions. That timing difference can matter when the amount at issue is modest and the cost of prolonged litigation starts to overshadow the claim itself. FINRA’s 2025 dispute resolution statistics
Here’s what this often means in general terms: the smaller the claim, the more pressure there is to keep process costs from overtaking the dispute. A written-submission format is one way FINRA tries to balance access and efficiency.
