Two ways of resolving a dispute outside a trial that are constantly confused - one produces an agreement you can walk away from, the other a decision you generally cannot appeal.
These are opposite processes and the difference is not a technicality. Mediation is an assisted negotiation. A neutral mediator has no power to decide anything; their function is to help the parties reach an agreement themselves. Nobody is bound unless and until they agree, and a party who does not like where it is going can stop. Arbitration is an adjudication. A neutral arbitrator hears both sides and issues a decision - an award - which is binding and enforceable in court much like a judgment.
The consequence people meet too late concerns appeal rights. A court judgment can generally be appealed for legal error. An arbitration award, under both federal and state arbitration law, can be set aside only on very narrow grounds - corruption, evident partiality, serious procedural misconduct, or the arbitrator exceeding their powers. An arbitrator who simply gets the law or the facts wrong has, in most cases, still produced a binding award. Choosing arbitration is largely choosing to give up appellate review.
Most people do not choose it deliberately. Arbitration clauses appear as standard terms in employment contracts, consumer credit agreements, mobile phone and software terms, nursing home admission papers and brokerage account documents, and courts enforce them routinely. Many are paired with a waiver of the right to participate in a class action, which for small individual losses is often the more consequential term of the two. Whether a particular clause binds a particular person is a real legal question, but the default expectation should be that it does.
Mediation carries much less risk and is frequently required rather than optional - many courts order parties to attempt it before trial, and it is close to standard in family cases. What is said in mediation is generally confidential and inadmissible later, which is what allows candid discussion. The point to hold onto is that a mediated settlement, once signed, is a binding contract: the freedom to walk away exists right up until the signature and not after it.
The moment worth paying for is before signing, not after the dispute - and specifically, reading whether an agreement contains an arbitration clause and a class action waiver, because that is where the rights are actually given up. Once a dispute exists, advice is most valuable in deciding whether a clause is enforceable against you at all and, if arbitration is unavoidable, in the arbitrator selection and the framing of the claim, because there is effectively no second chance. For mediation, a lawyer is often useful without attending: someone to tell you what the claim is realistically worth before you agree to a number.
