Is Mediation Confidential in California?
A plain-English look at California mediation confidentiality, with a clear reminder to consult independent legal counsel about specifics.
In short: In most cases, yes. California's Evidence Code generally keeps what is said and written for the purpose of a mediation out of later court and other noncriminal proceedings, and mediators generally cannot be made to testify about it. That protection has limits, though: it is not the same as total secrecy, some court programs work differently, and a signed agreement can become usable in court. Because the details depend on your situation, it is worth asking an independent attorney how the rules apply to you.
When people are not sure whether mediation is confidential, they often hold back. They avoid naming the thing that actually matters, soften an offer until it means nothing, or skip mediation altogether because they worry their words will be used against them later. That uncertainty has a cost: conversations stall, decisions get pushed to a courtroom, and families carry the conflict longer than they need to. California has fairly strong rules protecting mediation communications, but those rules have edges. This article walks through what the protection covers, where it stops, and what you can ask before you sit down at the table.
In plain English
In California, what you say in mediation generally cannot be used as evidence later in a civil or family court case. It is a strong protection, but it is not a promise that nobody will ever repeat anything, and there are exceptions.
The belief that everything in the room stays in the room
A lot of people come to mediation believing that confidential means sealed forever: nothing said can ever be repeated, shared or used by anyone. It is an understandable belief, and it is partly true, which is why it is easy to hold onto.
California's mediation confidentiality rules are found mainly in the Evidence Code, starting at section 1115. Their main job is to keep mediation communications out of evidence. Section 1119 generally provides that things said or written for the purpose of, in the course of, or under a mediation are not admissible or subject to discovery in a later arbitration, administrative hearing, civil case or other noncriminal proceeding. That is a meaningful protection. It is also a narrower idea than total secrecy.
Put simply, the law mostly controls what can be used in a legal proceeding. On its own, it does not necessarily stop someone from telling a friend or relative what happened in a session. Whether that kind of sharing is limited often depends on what the participants agree to in writing, which is one reason a written confidentiality agreement is common at the start of a private mediation.
How California's protection actually works, and where it stops
The protection is broad. It generally covers offers, admissions, notes, drafts and discussions made for the purpose of the mediation. Mediators are also generally not competent to testify about what happened in a mediation under Evidence Code section 703.5, with limited exceptions. California courts have applied these rules firmly, and they can reach further than people expect, including some private communications connected to the mediation. Because the protection is strong, it can also cut both ways: something you might later want a judge to hear may be off limits too.
There are important limits. A fact does not become protected just because it was mentioned in mediation: evidence that is otherwise available, such as a bank statement or a text message that already exists, generally stays usable through normal channels (Evidence Code section 1120). The participants can also agree in writing to allow certain disclosures. A written settlement agreement can be admissible if it meets the requirements in section 1123, for example if it says it is enforceable or binding, or words to that effect. That is by design: an agreement that could not be enforced would not be much use.
Family matters have another wrinkle. Court connected child custody mediation under the Family Code is not always the same as private mediation. In some California counties, the court's custody mediator may make a recommendation to the judge, which means what is said there can shape what the court hears. Mediators may also have duties, for example around safety, that sit outside these evidence rules. Separately, California requires attorneys to give their clients a written disclosure about mediation confidentiality before the client agrees to mediate (Evidence Code section 1129), which is a signal of how much weight the law gives this topic. If your matter also touches Texas, the rules there are different, and it is worth asking about them separately.
Ways to get clear on confidentiality before your first session
You do not need to become an expert in the Evidence Code to go into mediation with your eyes open. A few steps can make the picture clearer. Ask the mediator for the written confidentiality agreement ahead of time and read it before the first session, not in the lobby. Notice whether it covers only court use or also sharing with people outside the process. Ask whether the mediation is private or court connected, and, if it involves children, whether anyone involved makes recommendations to a judge.
It also helps to think about what you already have in writing outside mediation, such as financial records or messages, since those are generally treated differently from what is said in the session. Finally, consider having an independent attorney review both the confidentiality agreement and any settlement terms before you sign. A mediator, including a law trained mediator such as Marissa Chen, J.D., who is not a licensed attorney, can explain how the process works but cannot tell you how the law applies to your specific case. That is the job of your own legal counsel.
When mediation may help
Mediation may help when the people involved want room to speak openly, test ideas and explore options without worrying that a half formed proposal will be read aloud in court later. California's confidentiality rules are designed to support exactly that kind of candid conversation, and for many families and family businesses that openness is what makes progress possible. It can be a good fit when both sides can participate safely, share information honestly and make their own decisions.
Mediation is not the right fit for everyone. If there is a history of domestic violence, coercion or intimidation, if one person is hiding assets or refusing to share basic information, or if you need a public record or the full tools of the court process, such as formal discovery or orders a judge can enforce right away, a courtroom or another process may serve you better. Confidentiality can also work against you if you expect to rely later on something said during mediation. These are good things to talk through with independent counsel before deciding.
Questions to ask before conflict escalates
- Can I see the written confidentiality agreement before the first session, and does it limit sharing outside of court as well as use in court?
- Is this mediation private or connected to a court program, and will anyone make a recommendation to a judge?
- What happens to notes, drafts and documents created during the mediation once it ends?
- What wording would make a settlement agreement usable in court, and should my own attorney review it before I sign?
Common questions about mediation confidentiality in California.
In general, California's Evidence Code keeps mediation communications out of later civil and family proceedings. There are exceptions, including written agreements that allow disclosure and some court connected custody programs where a mediator may make recommendations. An independent attorney can tell you how these rules apply to your situation.
California law generally prevents mediators from testifying about what happened in a mediation, with limited exceptions. This is part of what allows people to speak candidly. Mediators may still have other duties, for example around safety, that are separate from the evidence rules.
Generally, no. Evidence that exists independently, such as financial records or messages, does not become protected just because it was discussed or shown in mediation. It can usually still be obtained and used through the normal legal process.
It depends on how it is written. Under California law, a written settlement agreement can be admissible if it meets certain requirements, such as stating that it is enforceable or binding. Many people have their own attorney review the wording before signing for exactly this reason.
