Is Mediation Confidential?

By Chad Foster, Family Law Attorney · Updated September 28, 2026

If you are heading into mediation to resolve a divorce, parenting dispute, or other family law matter, one worry usually surfaces first: can anything I say here be used against me later? In Washington, the answer is reassuring, though it comes with a few important exceptions worth understanding. The Law Office of Chad Foster helps Snohomish County families with family-law mediation.

Confidentiality has boundaries

Communications

Privilege generally applies

The statute protects covered mediation communications.

Existing evidence

Still independently usable

An existing document does not become protected merely by bringing it to mediation.

Exceptions and waiver

Check the specific rule

Signed agreements and other statutory exceptions require separate analysis.

The General Rule: What You Say in Mediation Stays Protected

Washington has adopted a version of the Uniform Mediation Act, found at chapter 7.07 RCW, and it gives mediation communications real legal protection. Under RCW 7.07.030, a mediation communication is privileged, is not subject to discovery, and is not admissible as evidence in a proceeding, unless the privilege is waived or an exception applies. That is a strong shield. It means the offers you float, the concessions you consider, and the candid conversations you have while trying to settle generally cannot be dragged into a later court hearing.

The privilege belongs to more than just you. Under RCW 7.07.030, a party to the mediation may refuse to disclose a mediation communication and may stop others from disclosing it, a mediator may refuse to disclose communications and may prevent disclosure of the mediator's own communications, and a nonparty participant may protect their own communications as well. So the protection covers the people around the table, not only the two spouses or parents.

There is one nuance people often misread. The statute protects communications made in mediation, but it does not turn otherwise usable evidence into a secret simply because it came up in a session. RCW 7.07.030 says evidence that is already admissible or discoverable does not become protected just because it was disclosed or used in a mediation. In plain terms, you cannot hide a bank statement or a text message from discovery by mentioning it during mediation. The document was always fair game, and it stays that way. You can discuss confidentiality concerns with your own attorney during mediation.

The evidence privilege is not the whole confidentiality question. RCW 7.07.070 makes mediation communications confidential to the extent the parties agree or other law or court rules provide. Check the mediation agreement before assuming every outside disclosure is forbidden by the privilege alone. A signed settlement raises a different question: whether the mediation agreement can be enforced.

Confidentiality Can Be Waived

The privilege is powerful, but it is not automatic in every scenario, and it can be given up. Under RCW 7.07.040, the privilege may be waived in a record or orally during a proceeding, but only if all parties to the mediation expressly waive it. If the mediator's own privilege is at stake, the mediator has to waive too, and the same is true for a nonparty participant's privilege. The point is that no single person can unilaterally strip away everyone else's protection, which keeps the shield meaningful.

The statute also addresses fairness. If someone discloses or makes a representation about a mediation communication that prejudices another person in a proceeding, that person loses the ability to hide behind the privilege, but only to the extent needed for the other side to respond. In other words, you cannot selectively reveal the helpful parts of a mediation and then claim confidentiality over the rest.

The Exceptions the Law Carves Out

Washington law lists specific situations where the privilege does not apply, and these are set out in RCW 7.07.050. A few are especially relevant to families. First, a signed settlement agreement coming out of mediation is not privileged. That is by design: the whole purpose of settling is to create an enforceable agreement, so the document that records the deal is meant to be usable. Second, threats to inflict bodily injury or commit a crime of violence are not protected, and neither is using mediation to plan or conceal a crime.

The statute is careful in the family context. RCW 7.07.050 provides that there is no privilege for a mediation communication sought to prove or disprove abuse, neglect, abandonment, or exploitation in a proceeding where a child or adult protective services agency is a party, unless that agency is participating in the mediation. Washington also allows a court, only after a private in camera hearing and a demanding showing of need, to pierce the privilege in a felony criminal proceeding or in a narrow contract dispute arising out of the mediation itself. These are not loopholes that swallow the rule. They are targeted carve-outs, and the statute limits how much of a communication can come in even when an exception applies.

What This Means for Families in Snohomish County

For most people going through a Snohomish County divorce or parenting case, the practical takeaway is encouraging. Mediation gives you a space to negotiate honestly without fear that your good-faith efforts to compromise will be used as ammunition if the case does not settle. That freedom is often what allows parents to reach a parenting plan they can both live with, or spouses to divide property without a bruising trial.

At the same time, understanding the edges of confidentiality matters. Knowing that a signed agreement may be enforceable, that pre-existing documents stay discoverable, and that safety-related disclosures are not shielded helps you use mediation wisely rather than assuming it is a cone of silence with no seams.
