TL;DR — Key Takeaways
- The three paths differ on one thing above all: who decides, and whether their decision binds you. A mediator decides nothing. An arbitrator usually decides everything, with almost no appeal. A judge or jury decides, with a real appeal.
- Mediation is not binding. It produces a settlement only if you agree to one, and in California that agreement generally has to be in writing and say so to be enforceable.
- California mediation is confidential by statute, and the confidentiality is broader than most people expect. It can reach communications between you and your own lawyer.
- Before you agree to mediate, your attorney must give you a printed one-page disclosure about that confidentiality and get your signature on it.
- Binding arbitration trades your appeal rights for speed and privacy. Review of an arbitration award is narrow.
- In consumer and employment arbitrations, the party that drafted the agreement has to pay arbitration fees within 30 days of the due date or face a material breach. A 2025 California Supreme Court decision confirmed that rule survives but rejected treating every late payment as an automatic forfeiture.
Which path fits your dispute comes down to who you want making the decision and how much finality you are willing to trade for speed. Mediation puts the decision back in your hands and binds you only if you agree. Arbitration hands it to a private decision-maker whose ruling is very hard to overturn. Trial hands it to a judge or jury and preserves a real right to appeal.
Often the choice is not yours alone. A contract you signed years ago may have already made it.
Mediation: nobody decides but you
A mediator is a neutral who helps the parties reach their own agreement. The mediator has no authority to rule, cannot compel anything, and does not report to the court on who was reasonable.
That is the source of mediation’s usefulness and its limits. Because nothing binds you, you can walk away. Because nothing binds the other side either, a party who is not negotiating in good faith can absorb a day of your time and money and leave.
Is California mediation binding? Not by itself. A settlement reached in mediation becomes enforceable only through a separate agreement. Under Evidence Code section 1123, a written settlement agreement prepared in the course of mediation is admissible and enforceable if it says it is binding, or enforceable, or words to that effect, or if all parties agree in writing to disclosure. An oral agreement can qualify under section 1118, but the conditions are specific. The practical rule: get it in writing before anyone leaves the room, and make sure the writing says it is binding.
The confidentiality is broader than people expect. Evidence Code section 1119 makes communications, negotiations, and writings made for the purpose of or in the course of a mediation inadmissible and not subject to discovery in later noncriminal proceedings. A mediator cannot testify about what happened. A mediator’s report or recommendation cannot be submitted to a court.
That protection is what makes candid negotiation possible. It also cuts in a direction clients rarely anticipate: California courts have applied mediation confidentiality to communications between a client and the client’s own attorney during a mediation, which can make a later claim against that attorney difficult to prove.
The Legislature responded with a disclosure requirement rather than an exception. Under Evidence Code section 1129, before you agree to participate in a mediation or a mediation consultation, your attorney has to give you a printed disclosure of the confidentiality restrictions and obtain your signed acknowledgment. The disclosure has to be in your preferred language, at least 12-point type, on a single page not attached to anything else, and signed and dated by both of you. It applies to every case except class and representative actions. Section 1129(e) is worth knowing too: an attorney’s failure to comply is not a basis to set aside an agreement reached in the mediation.
If a lawyer proposes mediation and no such page appears, ask for it.
Mandatory settlement conference. Different animal. An MSC is a court-ordered settlement session, usually before a judge or a judicial officer rather than a private neutral, scheduled as part of the case. It is not voluntary, and the confidentiality framework is not identical to a private mediation’s. Many cases go through both.
Arbitration: private, faster, and close to final
Arbitration is adjudication outside court. An arbitrator hears evidence and issues an award that, in binding arbitration, resolves the dispute.
How you end up there. Usually a clause in a contract you signed. If one side sues anyway, the other can petition to compel arbitration under Code of Civil Procedure section 1281.2. The court orders arbitration if it finds an agreement to arbitrate exists, unless a statutory exception applies. Those exceptions matter: the right to compel may have been waived, grounds may exist to revoke the agreement, or there may be pending litigation with a third party arising from the same transaction that creates a risk of conflicting rulings.
California also has judicial arbitration, under Code of Civil Procedure section 1775 and following. That is a court-annexed, non-binding process in certain cases, and a party dissatisfied with the award can request a trial de novo. Do not confuse it with contractual binding arbitration. The names are similar and the consequences are not.
What you give up. Review of an arbitration award is narrow. An arbitrator’s legal error, standing alone, is generally not a ground to vacate. If the arbitrator gets the law wrong, you usually live with it. That is the central trade.
What you gain. Privacy, a schedule that does not depend on a crowded civil calendar, a decision-maker who may have subject-matter expertise, and usually less time from filing to resolution.
What it costs. More than people expect at the outset. Court filing fees are modest and the judge’s time is free. An arbitrator bills hourly, the administering organization charges fees, and under Code of Civil Procedure section 1284.2 the parties generally bear their own expenses and share the neutral’s costs equally unless the agreement says otherwise. The savings show up in reduced duration, not in the decision-maker’s price.
A rule worth knowing if you are the consumer or employee. In consumer and employment arbitrations, the party that drafted the agreement must pay the arbitration fees within 30 days after the due date, and failure is a material breach that can let the other side withdraw from arbitration and go to court. In August 2025 the California Supreme Court held that this rule is not preempted by the Federal Arbitration Act, while rejecting the rigid reading several Courts of Appeal had adopted under which any late payment forfeited arbitration automatically. The statute is now read alongside ordinary relief-from-forfeiture principles, so an inadvertent delay is treated differently from strategic nonpayment. Note that federal district courts in California have reached the opposite conclusion on preemption, so the answer can depend on which courthouse you are in.

Trial: the slowest path, and sometimes the only one
Trial gives you a public record, full discovery, a jury if you want one in most civil cases, and a genuine right of appeal. It also gives you the longest timeline and the highest cost.
It is the right path when you need something the other two cannot produce: a precedent, a public finding, relief an arbitrator cannot grant, or leverage against a party who will not engage with anything less. It is also where you end up by default when there is no arbitration clause and settlement fails.
Most civil cases that are filed do not reach trial. That is not a failure of the system; it is the system working as designed, with the filing creating the structure in which settlement happens.
How the three compare
Who decides. Mediation, you do. Arbitration, a private neutral. Trial, a judge or jury.
What binds you. Mediation, only what you sign. Arbitration, the award, with narrow review. Trial, the judgment, subject to appeal.
Speed. Mediation can happen in weeks. Arbitration commonly runs months to a year or more. Trial is measured in years, with a statutory outer limit of five years to bring a civil case to trial.
Cost. Mediation is the cheapest by a wide margin. Arbitration and litigation are closer than the marketing suggests once the neutral’s fees are counted.
Privacy. Mediation and arbitration are private. Court filings are public.
Appeal. Only trial preserves a meaningful one.

Which disputes belong outside court
Some patterns recur.
Disputes where the relationship continues afterward, between business partners, family members, co-owners, or a landlord and a long-term tenant, generally do better in mediation. Litigation ends relationships.
Disputes where the facts are genuinely unclear and both sides have real exposure tend to settle, and mediating early saves the cost of discovering that.
Disputes over a documented sum against a solvent party often resolve on a demand letter or in small claims without any of this.
And some disputes should not go outside court. Where you need an injunction quickly, where a limitations period is about to run, where the other side has shown they respond only to a filed complaint, or where the legal question genuinely needs a published answer, court is the path. Filing as leverage covers what a filing actually changes.

Frequently Asked Questions
What is the practical difference between mediation, arbitration, and trial?
Mediation is a negotiation helped along by a neutral who decides nothing; you are bound only by what you agree to. Arbitration is private adjudication where an arbitrator issues an award that is binding and very difficult to appeal. Trial is public adjudication by a judge or jury, slower and more expensive, but with full discovery and a real right of appeal.
Is California mediation binding, and what happens if it fails?
Mediation itself is not binding. A settlement becomes enforceable through a separate agreement, and under Evidence Code section 1123 a written agreement prepared in mediation is generally enforceable if it states that it is binding or enforceable. If mediation fails, the case continues where it was, and what was said in the mediation stays confidential under Evidence Code section 1119.
How do the costs compare across the three paths?
Mediation is by far the cheapest, often a single day of a neutral’s time split between the parties. Arbitration and litigation are closer than expected: court filing fees are modest and judges are not billed hourly, while an arbitrator and the administering organization both charge. Arbitration usually saves money through a shorter timeline rather than a cheaper decision-maker.
What is a mandatory settlement conference and how does it differ from mediation?
An MSC is a court-ordered settlement session, typically conducted by a judicial officer as part of the case schedule, rather than a private process the parties choose. Mediation is voluntary, uses a neutral the parties select and pay, and operates under the Evidence Code’s mediation confidentiality provisions. Many cases go through both.
Which disputes are best resolved outside court?
Disputes where the relationship has to survive, where the facts are contested on both sides, or where the amount at stake is small relative to litigation cost. Court is the better path where you need urgent injunctive relief, where a deadline is about to run, or where the other side has demonstrated that only a filed case gets their attention.
