Mediation is a negotiation with a neutral third party in the room. It is not a hearing, the mediator does not decide anything, and nobody is bound unless they sign. What makes it useful in a business dispute is that it can resolve a matter before litigation consumes the relationship, the calendar, and the budget.
This page explains how business mediation works in California, what confidentiality does and does not protect, when it fits and when it does not, and what a lawyer does in a process where nobody is being judged.

What Is Business Mediation?
Business mediation is a confidential process in which a neutral person facilitates communication between disputing parties to help them reach a mutually acceptable agreement. Under California Evidence Code § 1119, communications and writings prepared for a mediation are generally inadmissible and not subject to discovery. Nothing binds anyone unless a settlement is signed, and under § 1123 a written mediation settlement agreement is enforceable only if it is signed by the settling parties and contains specific language.
Key Takeaways
- A mediator facilitates; they do not rule, and they cannot impose an outcome.
- Mediation confidentiality in California is unusually strong, with narrow exceptions.
- That same confidentiality means a deal reached in mediation may be unenforceable unless the written agreement contains the language § 1123 requires.
- Under § 1129, an attorney must give a client a printed confidentiality disclosure and obtain a signed acknowledgment before the client agrees to mediate.
- Mediation is voluntary — parties may leave at any time, and courts do not have inherent power to order parties into private mediation.
How Mediation Differs From Litigation and Arbitration
| Mediation | Arbitration | Litigation | |
| Who decides | The parties. The mediator has no authority to impose anything. | The arbitrator | A judge or jury |
| Binding | Only if the parties sign a settlement | Generally binding, with limited review | Binding, subject to appeal |
| Confidentiality | Protected by statute, with narrow exceptions | Depends on the agreement and forum rules | Filings are generally public |
| Control over outcome | Retained by the parties | Given up to the arbitrator | Given up to the court |
| Relationship | Can preserve an ongoing commercial relationship | Adversarial | Adversarial |
The distinction that matters most commercially is the last one. Litigation and arbitration produce a winner and a loser between parties who may still need to work together — a supplier, a co-owner, a landlord, a long-standing customer. Mediation is the only one of the three that can end a dispute without ending the relationship.
What California Confidentiality Actually Protects
California’s mediation confidentiality rules sit in Evidence Code §§ 703.5 and 1115 through 1129, and they are stronger than many people expect.
Under § 1119, no evidence of anything said in the course of a mediation is admissible or subject to discovery, and no writing prepared for the purpose of, in the course of, or pursuant to a mediation is admissible or subject to discovery. All communications, negotiations, and settlement discussions between participants in the course of a mediation are to remain confidential. A mediator’s report, opinion, recommendation, or finding may not be submitted to or considered by a court, and a mediator generally cannot testify about what occurred.
Two practical consequences follow:
You can speak candidly. An admission made while exploring settlement does not become a document in someone’s trial exhibit binder. This is what allows parties to discuss what a case is really worth rather than defending a position.
The protection cuts both ways. If the other side says something valuable in the room, that generally cannot be used later either. Mediation is not a discovery tool, and treating it as one tends to be obvious to everyone present.
Section 1120 preserves an exception for evidence that is otherwise admissible — a pre-existing contract does not become privileged because someone brought it to a mediation.
Making the Settlement Stick
This is where deals fail, and it is the strongest reason to have counsel involved.
Because § 1119 makes mediation writings inadmissible, a settlement agreement reached in mediation can itself be caught by the very confidentiality that made the discussion possible — leaving a party unable to prove the deal in order to enforce it.
Section 1123 addresses this. A written settlement agreement prepared in the course of or pursuant to a mediation is not made inadmissible if it is signed by the settling parties and one of the statutory conditions is met — for example, that the agreement provides it is admissible or subject to disclosure, or words to that effect.
Two failure modes follow directly:
- An unsigned agreement. A term sheet everyone verbally accepted at 9 p.m. but nobody signed may remain confidential and unenforceable.
- A signed agreement missing the required language. The signatures alone do not satisfy the section; the document has to say the right thing.
Section 1124 addresses the narrow circumstances in which an oral agreement reached through mediation may fall outside confidentiality, and § 1118 sets out how an oral agreement may be recorded. These are technical provisions, and getting them wrong at the end of a long day is a common and expensive mistake.
The Disclosure Your Attorney Must Provide
Under Evidence Code § 1129, except in a class or representative action, an attorney representing a client participating in a mediation or a mediation consultation must — as soon as reasonably possible before the client agrees to participate — provide the client with a printed disclosure of the confidentiality restrictions described in § 1119, and obtain a printed acknowledgment signed by the client stating they have read and understand those restrictions. An attorney retained after a client has already agreed to mediate must comply as soon as reasonably possible after being retained.
If a lawyer proposes mediation without this step, that is worth asking about. The requirement exists because clients have historically been surprised, after the fact, by how much confidentiality gives up.
When Mediation Fits a Business Dispute
Mediation tends to be worth trying where:
- An ongoing commercial relationship has value — partners, suppliers, distributors, franchisees, landlords and tenants
- Confidentiality itself matters, because litigation filings are public
- The dispute is fundamentally about money or terms rather than principle
- Both sides have realistic exposure and neither has a clearly winning position
- The cost or delay of litigation would exceed what is genuinely in dispute
- A creative outcome is possible — a revised contract, a payment schedule, a buyout, a transition period — that a court could not order
It tends not to fit where a party needs an urgent injunction, where a legal question genuinely needs deciding, where a party will not participate meaningfully, where information asymmetry means one side cannot evaluate the dispute yet, or where fraud or bad faith makes any negotiated outcome untenable.
An honest assessment of which situation you are in is more useful than an assumption either way. Our California civil litigation page covers the alternative.
What a Lawyer Does in Mediation
Mediation is not a hearing, so the work looks different from a trial:
- Before. Assessing the realistic litigation outcome, because a settlement is only sensible measured against the alternative. Preparing the mediation brief, gathering the documents that make a position credible, and agreeing the § 1129 disclosure.
- Choosing the mediator. Subject-matter familiarity and style matter, and this choice is often more consequential than anything said on the day.
- During. Presenting the case to the other side rather than to a judge, evaluating offers against the litigation alternative, and advising on what a proposed term actually means.
- At the close. Drafting or reviewing the settlement agreement so it satisfies § 1123 and is enforceable — the step most often rushed.
- After. Implementation, and enforcement if the other side does not perform.
Business Disputes We Handle
Our business practice covers contract and breach of contract disputes, partnership and shareholder disagreements, commercial landlord and tenant matters, vendor and supplier disputes, disputes over business sales and purchases, and employment-related disputes on the business side. Related work is covered on our California business law, real estate, and employment law pages.
Business Mediation in San Mateo and on the Peninsula
Our office at 15 North Ellsworth Avenue, Suite 105, San Mateo, CA 94401 works with businesses across the Peninsula. Two local factors shape these disputes. Commercial relationships here tend to be dense and repeated — a supplier, a landlord, a co-founder, or a channel partner is frequently someone a business will encounter again, which raises the value of resolving a matter without a public fight. And confidentiality matters commercially in a market where funding, acquisition, and partnership conversations are ongoing, since litigation filings are public and turn up in diligence.
Where a matter does proceed to court, civil matters for this county are generally heard in the San Mateo County Superior Court. Details about the office are on our San Mateo page.

Business Mediation Frequently Asked Questions
A confidential process in which a neutral person facilitates communication between disputing parties to help them reach a mutually acceptable agreement. The mediator has no authority to decide anything, and no party is bound unless a settlement is signed.
Yes, and the protection is broad. Under Evidence Code § 1119, statements made and writings prepared for a mediation are generally inadmissible and not subject to discovery, and a mediator's report or opinion may not be considered by a court. The rules sit in Evidence Code §§ 703.5 and 1115 through 1129. Exceptions are narrow, and § 1120 preserves evidence that is otherwise admissible.
It can be, but only if it is done correctly. Because § 1119 makes mediation writings inadmissible, § 1123 provides that a written settlement agreement escapes that protection where it is signed by the settling parties and satisfies one of the statutory conditions — for example, stating that it is admissible or subject to disclosure. An unsigned term sheet, or a signed agreement missing that language, may be unenforceable.
Courts have various case-management tools and many cases are referred to court-connected ADR programs, but the essence of mediation is that it is voluntary, and courts do not have inherent power to compel parties into private mediation. A contract may separately require mediation before litigation or arbitration.
An arbitrator decides the dispute and the award is generally binding with limited review. A mediator decides nothing and facilitates an agreement the parties reach themselves. In mediation the parties keep control of the outcome; in arbitration they hand it over.
Mediator fees are commonly shared between the parties, though the allocation can be negotiated and is sometimes addressed in the underlying contract. Each side generally bears its own attorney's fees unless a contract or statute provides otherwise.
The dispute continues along whatever path it was already on, usually litigation or arbitration. Because of § 1119, what was said in the mediation generally cannot be used afterward, so an unsuccessful mediation does not typically damage a party's position in the case that follows.
Under Evidence Code § 1129, except in a class or representative action, your attorney must provide a printed disclosure of the § 1119 confidentiality restrictions and obtain your signed acknowledgment before you agree to participate in a mediation or mediation consultation. An attorney retained afterward must comply as soon as reasonably possible.
That depends on what winning would cost and how confident the assessment is. Litigation carries expense, delay, public filings, and uncertainty even for a strong position. Mediation is worth evaluating against the realistic litigation outcome rather than against the best-case one — but where a matter genuinely needs a decision, mediating for its own sake is not useful.
Business disputes are commonly handled hourly, sometimes with alternative arrangements depending on the matter. Mediator fees are separate and usually shared. We discuss fees before any work begins, and initial consultations are free.
