The Modern Mediation Brief

Most mediation briefs read like recycled motion papers, and that makes them far less useful than they could be. A modern brief should be a problem-solving tool that orients the mediator, sets a realistic path to resolution, and uses confidentiality strategically rather than reflexively.

Why Traditional Mediation Briefs Miss the Mark

In many litigated matters, mediation briefs are treated as one more advocacy filing: long, positional, and focused on “winning” the case on paper. Lawyers paste in sections from prior motions, over-argue liability, and bury the few facts the mediator actually needs to help the parties move the case.

This approach undercuts mediation’s core value: candid, interest-based negotiation in a confidential setting. In the Philadelphia region, where courts and mediation providers routinely stress efficiency and early case resolution, an over-litigated brief can make mediation feel like “disguised trial prep” instead of a serious opportunity to resolve the dispute.

Two-Track Briefing: Shared and Confidential Memoranda

A better model is to separate what must be shared from what truly needs to be kept private, through two coordinated documents: a non-confidential Pre-Mediation Memorandum exchanged among the parties, and a confidential Memorandum for the mediator’s eyes only.

What Belongs in the Non-Confidential Memorandum

The non-confidential pre-mediation memorandum should be concise, shareable, and focused on orienting both the mediator and the other side.

• Brief procedural and relational history: Every effective brief starts with a short story: who the parties are, what went wrong, and how the dispute has progressed procedurally.
• Overview of the applicable law: Offer an overview of the applicable law, not an appellate brief. One to two pages is usually enough to set out the governing standards.
• Facts supporting your client’s interests as applied to the law: This is where you “connect the dots”: what evidence supports your theory of liability or defense, how damages are calculated, and which factual disputes really matter.
• History of any settlement discussions: Provide a brief rundown of where settlement discussions stand.

What Belongs in the Confidential Memorandum

The confidential pre-mediation memorandum is where you can be fully candid with the mediator about dynamics that cannot (yet) be shared with the other side.

• Facts not disclosed in the shared memo: Use this section to flag facts you are not ready to disclose publicly, but that materially affect risk or leverage (e.g., insurance issues, internal politics, or cash-flow constraints).
• Strengths, weaknesses, and impediments to resolution: A good brief identifies significant factual and legal strengths and weaknesses, as well as impediments to resolution like regulatory concerns or insurance carrier dynamics.
• The realistic path to resolution: You should devote real attention to a realistic path to resolution: proposed options, monetary ranges, and potential deal structures, informed by the status of settlement discussions to date.

Drafting Style: Clear, Concise, and Intentional

• Be clear and concise: Focus on what the mediator needs to know to understand the dispute and design a negotiation strategy.
• Avoid over-argument: One focused paragraph on why you think you win is usually enough.
• Support key points with evidence: Attach or link only what truly matters, and point the mediator to exactly where they can find it.
• Share what you can: Use confidential submissions only when truly necessary.

Bringing This to Your Next Mediation

Reframing how you write mediation briefs is one of the easiest ways to increase the odds of settlement. A well-structured non-confidential memo, paired with a candid confidential submission, helps the mediator understand both the legal merits and the real-world constraints that drive decision-making.

More importantly, a brief that emphasizes a realistic path to resolution signals that you and your client are showing up to resolve the conflict, not just to rehearse for trial. That intention often makes the difference between a long day that goes nowhere and a hard-won, durable agreement.
