Mediation vs. arbitration

Mediation and arbitration at a glance

	Mediation	Arbitration
Who decides the outcome	The parties themselves	The arbitrator
What the neutral does	Facilitates a negotiation	Hears evidence and rules
Is the result binding	Only through a settlement agreement the parties sign	Yes. The award is binding and enforceable in court
Range of outcomes	Any terms the parties agree to, including remedies a court could not order	The relief available under the contract and the governing law
Typical duration	One session, occasionally a few	Several months from filing to award
Relative cost	Lower. One neutral, one day, limited exchange of information	Higher. Filing fees, discovery, briefing, and hearing time
Confidentiality	Confidential by agreement, and protected by statute in many states	Private, though an award can surface in enforcement proceedings
Review	Not applicable. There is no decision to appeal	Narrow. The grounds to vacate an award are limited by statute
Effect on the relationship	Built to preserve it	Adversarial by design

How the two processes differ

Both processes sit outside the courtroom, and that shared setting conceals how differently they work. Mediation is a negotiation that a neutral facilitates. Arbitration is an adjudication that a neutral decides. Nearly every other distinction follows from that one.

In mediation, the mediator has no authority to impose a result. The mediator structures the conversation, moves between the parties in private caucus, tests each side’s assumptions about its own position, and helps the parties assemble an agreement they can live with. Where no agreement is reached, the parties leave with their legal rights untouched.

In arbitration, the arbitrator holds the authority a judge would hold. Each side presents evidence and argument at a hearing. The arbitrator then issues an award, and that award is binding and enforceable in court under the Federal Arbitration Act. The parties surrender control over the outcome in exchange for a decision that ends the matter.

Where each one fits

The choice is rarely a question of preference. It follows from what the dispute actually needs.

Mediation fits where a relationship survives the dispute. Business partners, cofounders, employers and employees, and parties to a long-term contract all have reason to prefer a resolution they authored over one imposed on them. It also fits where the remedy a party genuinely wants lies outside a court’s power, such as a reference letter, an acknowledgment, a change to a reporting line, or a restructured deal.

Arbitration fits where the parties need a decision and cannot reach one. It suits matters that turn on a contested question of fact or contract interpretation, matters where a public judgment would be unwelcome, and matters governed by a contract that already requires it. Technical disputes benefit as well, since the parties can select a neutral who understands the industry rather than accepting whichever judge is assigned.

Cost, time, and the odds of resolution

The practical differences carry as much weight as the doctrinal ones.

Mediation is the shorter and less expensive path. Most matters are set for a single day, the exchange of information is whatever the parties choose, and there is one neutral rather than a panel. The rate of resolution is also high. Roughly seventy-two percent of the mediations the Equal Employment Opportunity Commission conducted in fiscal year 2023 ended in a resolution. A process that settles most of what enters it, in a day, deserves consideration before the more formal alternative.

Arbitration inherits more of litigation’s structure, and more of its cost. There are filing and administrative fees, an exchange of documents, briefing, and hearing time billed by the neutral. What that expense buys is finality. The grounds to vacate an award are narrow by statute, which means an arbitration award generally closes the matter rather than opening the next stage of it.

Using both in a single dispute

The two are not mutually exclusive, and treating them as a binary is the most common error in a dispute resolution clause.

A stepped clause requires the parties to attempt mediation before either may file for arbitration. It costs little, it resolves a meaningful share of matters at the cheaper stage, and it reserves arbitration for what mediation cannot settle. Med-arb goes further, appointing one neutral to mediate and then, if the matter does not settle, to arbitrate it. Med-arb is efficient, and it carries a genuine tension. The neutral who ultimately decides the case has already heard each party’s confidential caucus positions. Some parties accept that trade deliberately. Others appoint a separate neutral for the arbitration phase, which protects the candor that makes mediation work.

Choosing between them

Four questions usually settle the choice. Does this matter need a decision, or does it need an agreement? Does the relationship continue afterward? Does an existing contract already dictate the forum? Would the remedy that solves the problem be one a court could order?

Where the answers point toward an agreement, mediation is the first move, and arbitration remains available if the matter does not settle. Where they point toward a decision, arbitration is the honest choice, and the parties are better served by going there directly than by spending a day in a process neither of them intends to complete.
