What Not to Say in Divorce Mediation in California

If you and your spouse are heading into divorce mediation in California, the statements that tend to cause trouble include blame about the past, ultimatums, insults about each other, guesses about what the other intends, and casual remarks about money offered in place of real financial disclosure. None of these is forbidden. Each one tends to make agreement harder to reach.

Most people facing a first mediation session are not worried about legal theory. They are worried about saying the wrong thing in a room, or on a screen, with someone they used to share a life with. Some of that worry is about tone, and some is about whether a careless sentence could later be used in court. Some is about the children, or the house, or a number that has not been discussed out loud yet. This article walks through how divorce mediation works in California, whether in San Diego or online anywhere in the state, which kinds of language tend to stall it, and what the law says about disclosure, confidentiality, custody and support, so that you and your spouse can go in knowing what the words you use actually carry.

What Divorce Mediation Is — and What It Is Not

California defines mediation in Evidence Code section 1115 as "a process in which a neutral person or persons facilitate communication between the disputants to assist them in reaching a mutually acceptable agreement." The mediator is that neutral person. The mediator's job is to help you and your spouse talk to each other well enough to reach terms you both accept.

The definition also shows what a mediator does not do. A mediator does not represent either spouse or argue for either spouse. A mediator is not either spouse's lawyer and does not decide custody, support or property for you. In private mediation, Evidence Code section 1121 generally keeps the mediator from sending a court any report, evaluation or recommendation about the mediation, other than a report required by court rule or other law that states only whether an agreement was reached, unless all parties expressly agree otherwise in writing or orally as the Evidence Code allows. Whatever is decided is decided by the two of you.

Either spouse may have a lawyer of their own, before sessions, during them, or only to review a draft agreement. The law does not require this, and it does not forbid it.

Private divorce mediation is also separate from the court's own custody mediation. Family Code section 3160 requires each superior court to make a mediator available. When custody or visitation is contested, Family Code section 3170 has the court send those issues to that court mediator. In San Diego County, that service is child custody recommending counseling with the court's Family Court Services. It has its own rules, covered below, and it is not the same thing as a private mediation you and your spouse choose. Mediation may make a divorce simpler for some couples, depending on the couple and the issues. It is not a shortcut and it carries no guarantee.

Language That Undermines the Process

Blame is the most common thing that pulls a session off course. Statements such as "This only happened because you…" or "You always…" reopen old arguments about the marriage instead of addressing the issue in front of you, such as a parenting schedule or what happens to a retirement account. A mediator can let some of this be voiced, because feelings are real. When blame becomes the main subject, though, the time goes to the past and the decisions stay where they were.

Ultimatums work differently, but they lead to the same place. "I will never agree to that" or "Either I keep the house or there's no deal" announces an ending before the conversation has started. Mediation depends on room to look at options, test them and adjust them. An absolute position closes that room. Couples often find there is a real concern underneath, such as staying near a school or keeping housing costs manageable, and the concern can be discussed even when the ultimatum cannot.

Disparaging or contemptuous language about the other spouse tends to cause lasting damage. That includes name-calling in the session, comments about the other parent made in front of the children, and sharp texts or emails that later come up in conversation. Once one person feels mocked, the focus usually shifts to defending against the insult and away from solving the problem.

A quieter pattern is speaking for the other person. "She just wants revenge" or "He doesn't actually care about the kids" claims to know someone else's motive. It also takes away their chance to say what they want. Mediation tends to move when each spouse states their own interests and hears the other's in the other's own words.

None of these patterns makes a person a bad participant. They are what stress sounds like. Recognizing them is often enough to slow down and say what you mean instead.

Financial Disclosures and What Mediation Cannot Replace

Mediation does not remove the duty of financial disclosure. California requires each spouse to serve formal declarations of disclosure, signed under penalty of perjury on Judicial Council forms, whether the divorce is mediated, negotiated or tried. A sentence in a session such as "There's nothing else, trust me" is not a disclosure.

The first is the preliminary declaration of disclosure, a sworn listing of assets, debts and income that includes the tax returns the declarant filed in the two years before serving it. Under Family Code section 2104(f), the petitioner serves it with the petition or within 60 days of filing the petition. The respondent serves it with the response or within 60 days of filing the response. If the petitioner served the summons and petition by publication or posting under a court order and the respondent files a response before a default judgment is entered, the petitioner has 30 days from that response. The parties can extend these time periods by written agreement, or the court can extend them by order. The general duty also has exceptions, including a court order for good cause.

The second is the final declaration of disclosure, served with a current income and expense declaration. Under Family Code section 2105(a), except by court order for good cause, these are due before or at the time the parties enter into an agreement resolving property or support issues other than temporary support. If the case goes to trial, they are due no later than 45 days before the first assigned trial date. Spouses can mutually waive the final declaration. Under section 2105(d), the waiver must be executed under penalty of perjury in open court or by separate stipulation. Among the representations it must include are that both parties have completed and exchanged their preliminary declarations, that both have completed and exchanged current income and expense declarations including all material facts about earnings, accumulations and expenses, that both have fully complied with their disclosure duties and fully updated their preliminary declarations, including characterization, valuation and obligation amounts, and that the waiver is knowingly, intelligently and voluntarily entered into by each party.

Perjury on either declaration may be grounds for setting aside the judgment, or part of it. That is why a spoken estimate of a bank balance, a business's income or a debt does not stand in for the sworn documents. The practice's article on financial disclosure in divorce mediation covers the forms in more detail.

Confidentiality in Mediation — What It Covers and What It Does Not

California's general rule is set out in Evidence Code section 1119. Except as the Evidence Code's mediation chapter otherwise provides, what is said and written for or during a mediation or a mediation consultation is generally not admissible or subject to discovery in later noncriminal proceedings where testimony can be compelled. "All communications, negotiations, or settlement discussions by and between participants in the course of a mediation or a mediation consultation shall remain confidential."

That protection is strong, but it is not absolute. The chapter contains exceptions. One that matters to divorcing couples is Evidence Code section 1123. A written settlement agreement prepared in or under a mediation and signed by the settling parties is not made inadmissible or protected from disclosure by the chapter if any of these conditions is met: the agreement says it is admissible or subject to disclosure, or words to that effect; it says it is enforceable or binding, or words to that effect; all parties expressly agree in writing, or orally as section 1118 allows, to its disclosure; or it is used to show fraud, duress or illegality relevant to an issue in dispute. A mediated divorce agreement meant to become part of a judgment is often written to be binding, so it is not always private.

Evidence Code section 1115(c) defines a "mediation consultation" as a communication between a person and a mediator for the purpose of initiating, considering or reconvening a mediation, or retaining the mediator. How the law treats any particular conversation depends on its facts, so it is safer not to assume that an early call is covered.

Except in a class or representative action, if a spouse has a lawyer, Evidence Code section 1129 requires that lawyer to give the client a printed disclosure of the confidentiality restrictions — on a single page, in at least 12-point font, in the client's preferred language — and obtain the client's signed, dated acknowledgment, as soon as reasonably possible before the client agrees to participate. If the lawyer is retained later, the lawyer does this as soon as reasonably possible after being retained.

The court's custody mediation follows different rules. Evidence Code section 1117(b) says the chapter does not apply to proceedings under the Family Code's court mediation chapter beginning at section 3160. Those proceedings are held in private and are confidential under Family Code section 3177.

Child Custody and Support: What Not to Assume in Mediation

A common assumption about child support is that parents can settle on any figure they like. Under Family Code section 4065(a), unless prohibited by applicable federal law, parents may stipulate to an amount, subject to the court's approval. The court will not approve an amount below the guideline formula unless the parents declare all of the following: they are fully informed of their rights concerning child support; the order is being agreed to without coercion or duress; the agreement is in the best interests of the children; the children's needs will be adequately met by the stipulated amount; and the right to support has not been assigned to the county and no public assistance application is pending. A statement in a session such as "We'll just call it zero" is not something the court can simply approve. The practice's page on child support mediation goes further into the guideline.

A second assumption is that all family law mediation is optional. Under Family Code section 3170, when a pleading shows that custody or visitation is contested, the court must set the contested issues for mediation. In San Diego County, that is child custody recommending counseling with the court's Family Court Services, which is part of the Superior Court of California, County of San Diego. Under Family Code section 3183(a), except as provided in section 3188, the court's mediator may, consistent with local court rules, submit a recommendation on custody or visitation to the court, if the recommendation is first given in writing to the parties and their attorneys before the hearing. That counselor's input can matter. The judge decides. Family Court Services handles domestic violence cases under a separate written protocol approved by the Judicial Council, as section 3170(b) requires. The practice is not connected to that court process. More on how it works appears in the article on child custody mediation.

In any custody discussion, private or court-connected, the language that tends to hurt most is language that treats the children as a prize. That includes talk of "winning" custody, remarks that shrink the other parent's role, and confident claims about what the children "really" want that the other parent has never heard. Parents who focus on schedules, routines and how the children will move between homes usually find more to work with.

When Mediation May Not Be the Right Setting

If you are in immediate danger, call 911.

Safety comes first, before any question about what to say. Where there has been domestic violence, coercion or a protective order, mediating face to face or screen to screen with the other spouse may not be safe or fair, and no one should feel pushed into it. Mediation depends on each person being able to speak freely and say no without fear. When one spouse is afraid of the other, that condition is missing.

Mediation also may not fit every couple for other reasons, such as when one spouse cannot participate freely or financial information is being kept hidden. This is not a judgment about anyone. It reflects that a process built on a "mutually acceptable agreement" needs two people who can both accept or refuse. The practice's article on when mediation is not appropriate discusses these situations calmly and in more depth.

If You'd Like to Talk Through How Mediation Would Work for You

Knowing what tends to derail a session is useful. Seeing how disclosure, confidentiality and the child support guideline apply to your own family is a different conversation. A consultation can cover how the mediation process works, which types of issues couples typically address together, which documents the disclosure rules call for, and how private mediation differs from the court's custody process. A consultation is not where anyone decides for you or your spouse. Simple Divorce Mediation works with couples in San Diego County and, online, anywhere in California. For more on the documents and decisions involved, see the article on preparing for divorce mediation.
