The core difference between arbitration and mediation is who controls the outcome. In mediation, a neutral facilitator helps you and the other side try to reach your own agreement, and nothing is binding unless you both sign off. In arbitration, a neutral hears both sides and then issues a decision that binds you whether you like it or not. Everything else — cost, speed, formality, your right to appeal — flows from that one distinction.
How Mediation Works
Mediation is a guided conversation. A trained neutral, the mediator, helps both sides communicate, identify what they actually need, and explore options. The mediator does not decide who is right and cannot force anyone to agree to anything. Sessions are informal, usually at a conference table, and the mediator typically meets with both parties together before shuttling between them in private caucuses to test proposals.
The process is confidential. Many states have adopted versions of the Uniform Mediation Act, which protects mediation communications from being disclosed in later court proceedings. That protection is part of what makes the process work: people speak more candidly when they know their words cannot be used against them later.
Nothing in mediation binds you until both sides sign a written settlement agreement. Once signed, it becomes an enforceable contract. If the other side later breaks the deal, you sue for breach of contract like you would with any other agreement. If no deal is reached, mediation simply ends, and both sides remain free to arbitrate, litigate, or walk away.
How Arbitration Works
Arbitration looks more like a trial, though simpler and faster. Each side presents evidence, calls witnesses, and makes arguments to a neutral arbitrator or a three-arbitrator panel. The arbitrator then issues a written decision called an award.
The Federal Arbitration Act, codified at 9 U.S.C. §§ 1–16, governs most arbitration in the United States. Section 2 of the FAA declares written arbitration agreements involving commerce “valid, irrevocable, and enforceable,” placing them on equal footing with other contracts.1Office of the Law Revision Counsel. 9 USC 2 – Validity, Irrevocability, and Enforcement of Agreements to Arbitrate If one side refuses to honor an arbitration agreement, the other can petition a federal court to compel arbitration under Section 4.2Office of the Law Revision Counsel. 9 USC 4 – Failure to Arbitrate Under Agreement; Petition to United States Court
Most arbitration awards are binding. The losing side has to comply, and the options for challenging the result are very narrow. That finality is arbitration’s main selling point for parties who want a definitive end to the dispute. It is also the biggest risk, because you are largely stuck with the outcome even if you think the arbitrator got it wrong.
Side-by-Side Differences That Actually Matter
Beyond who controls the result, several practical differences shape the choice:
- Formality: Mediation is a structured conversation. Arbitration is a simplified trial with evidence, testimony, and procedural rules.
- Outcome: Mediation produces a settlement only if both sides agree. Arbitration produces a binding award regardless of whether the loser agrees.
- Confidentiality: Both are more private than court, but mediation offers stronger statutory protection for what gets said during the process.
- Speed: Mediation can wrap up in a single day. Arbitration typically takes weeks or months, still faster than most litigation.
- Discovery: Mediation has no formal discovery; parties share what they choose. Arbitration allows limited discovery, usually far less than a court would permit. Under FAA Section 7 an arbitrator can summon witnesses and documents, but several federal appeals courts have held this power does not extend to pre-hearing subpoenas against third parties.3Office of the Law Revision Counsel. 9 USC 7 – Witnesses Before Arbitrators; Fees; Compelling Attendance
- Relationship impact: Mediation is collaborative and tends to preserve working relationships. Arbitration is adversarial by design.
The discovery point can cut either way. If you need the other side’s internal documents to prove your case, the limited discovery available in arbitration may leave you short of the evidence you need. If you want to avoid years of document review and depositions, limited discovery is a feature, not a bug.
Can You Challenge the Result
A signed mediation settlement is enforceable as a contract. If the other side breaks it, you sue for breach. How well that enforcement works depends on how carefully the agreement was drafted, so the terms need to be specific and in writing.
An arbitration award is enforceable more like a court judgment. You take it to a federal or state court and have it confirmed, which opens up the usual collection tools. The catch: the losing party has almost no way to challenge the result. Under Section 10 of the FAA, a court can vacate an award only on four narrow grounds:4Office of the Law Revision Counsel. 9 USC 10 – Same; Vacation; Grounds; Rehearing
- The award was procured through corruption or fraud.
- The arbitrator had an undisclosed conflict or displayed evident partiality.
- The arbitrator engaged in misconduct, such as refusing to hear relevant evidence or refusing a justified postponement.
- The arbitrator exceeded their powers or failed to issue a definite award.
Those are the only statutory grounds. Disagreeing with how the arbitrator weighed the evidence or applied the law is not enough. This is the fundamental difference from trial court, where you can appeal legal errors. In arbitration, you essentially get one shot.
Cost and Speed
Both processes cost less than full litigation, but the numbers vary by provider, complexity, and the neutral’s hourly rate.
Mediation is generally cheaper because it involves fewer sessions and less preparation. Private mediator rates typically run $100 to $500 per hour, with some charging flat half-day or full-day rates. Court-annexed programs sometimes offer reduced or free initial hours. Because many mediations resolve in a single session, total costs often stay well below arbitration.
Arbitration adds filing fees, administrative charges, and the arbitrator’s time. At JAMS, a large private ADR provider, the filing fee for a two-party arbitration is $2,000, with a 13% case management fee assessed on the arbitrator’s professional fees. For consumer disputes, JAMS caps the consumer’s share of the filing fee at $250; for employment disputes, the employee pays $400.5JAMS. Arbitration Schedule of Fees and Costs Arbitrator hourly rates are set individually and can range from several hundred to over a thousand dollars.
Attorney fees are usually the biggest expense in either process. Because mediation is shorter and less adversarial, legal costs run lower than in arbitration, which in turn run lower than in litigation.
When You Don’t Get to Choose
For many disputes, the process is already decided. Mandatory arbitration clauses appear in employment agreements, credit card terms, cell phone contracts, nursing home admissions, and countless other everyday contracts. By signing, you agreed to resolve future disputes through arbitration instead of in court.6FDIC Information and Support Center. Q: What Is Mandatory Arbitration? Research estimates that over 60 million American workers are subject to mandatory employment arbitration.
Many of these clauses also include class action waivers that prevent you from joining with others who were harmed the same way. In 2018, the Supreme Court upheld such waivers in Epic Systems Corp. v. Lewis, ruling the FAA requires courts to enforce arbitration agreements as written, including provisions for individualized proceedings. The practical effect: for many workplace and consumer disputes, your only option is to pursue a claim alone before an arbitrator.
One major exception exists. The Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act, signed on March 3, 2022, allows people alleging sexual assault or sexual harassment to void a pre-dispute arbitration clause and bring the claim in court instead.7Congress.gov. H.R.4445 – Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act of 2021 The choice belongs to the person making the allegation, regardless of what the clause says. The law applies to disputes arising on or after its enactment date.
Outside that statute, you can still challenge an arbitration clause on standard contract grounds. The FAA’s own text preserves defenses like fraud, duress, and unconscionability.1Office of the Law Revision Counsel. 9 USC 2 – Validity, Irrevocability, and Enforcement of Agreements to Arbitrate Courts have found clauses unconscionable when, for example, terms were buried in fine print the consumer had no real chance to negotiate and the provisions were overwhelmingly one-sided. Winning that argument is difficult; most courts enforce the clauses as written.
One more wrinkle on the mediation side: although mediation is voluntary in the sense that no one can force a settlement, courts across the country routinely order parties to attend mediation before trial. You have to show up and participate in good faith. You do not have to accept any particular deal, and if mediation fails the case returns to the court’s docket.
Med-Arb: The Hybrid
Some disputes use a two-stage process called med-arb. Parties start in mediation, and if they cannot settle, the process converts to arbitration where the same neutral issues a binding decision. The appeal is efficiency: collaborative first, final resolution guaranteed.
The risk is real. Parties may hold back during mediation knowing the mediator could become the arbitrator, and confidential admissions could consciously or unconsciously influence the later decision. Some med-arb agreements address this by bringing in a different neutral for the arbitration phase, though that sacrifices some of the efficiency.
Which One to Pick
If you value control over the outcome, want to preserve a relationship, and are willing to compromise, mediation is almost always the right starting point. It is cheaper, faster, and leaves both sides with a say in the result. Even when mediation does not produce a full settlement, it often narrows the issues and makes any arbitration or litigation that follows more efficient.
Arbitration makes more sense when the parties are too far apart to negotiate, when you need a binding decision to end the dispute, or when the other side refuses to engage in good faith. It is also the only option when a contract requires it, which is the reality for a significant share of employment and consumer disputes.
Before assuming you can pick, check your employment agreement, your service contracts, and any relevant business agreements. If you signed a mandatory arbitration clause, mediation may still be available as a first step, but arbitration is the backstop if talks fail, and court is off the table unless one of the narrow exceptions applies.
