The most important thing to know about what not to say to your ex is that anything you put in a text, email, or voicemail can end up in front of a judge. Avoid threats, insults, admissions about drinking or drug use, and anything about the children that you would not want read aloud in court.
If you are going through a separation, divorce, or a custody dispute, your ex is not the only audience for your words anymore. Attorneys, mediators, and family court judges may all eventually read what you send. One angry message sent at midnight can undo months of careful behavior. This guide walks through the specific statements that tend to cause the most damage, why they matter under California law, and what to say instead.
Why What Not to Say to Your Ex Matters in a Family Law Case
In a family law case, your words are evidence. Text messages, emails, voicemails, and social media posts are regularly introduced in California family court, and they can shape how a judge sees your credibility, your judgment, and your ability to co-parent.
California is a no-fault divorce state, which means you do not have to prove your spouse did anything wrong to get divorced, and simple marital misconduct usually will not change how property is divided. That surprises a lot of people. But no-fault does not mean your behavior is invisible. When children are involved, conduct matters a great deal.
Under California Family Code Section 3011, a judge deciding custody must weigh the health, safety, and welfare of the child, any history of abuse, and the nature of each parent’s contact with the child. A pattern of hostile, threatening, or unstable messages can become part of that picture. The parent who stays calm and child-focused on paper is often the parent who looks more reasonable to the court.
10 Things Not to Say to Your Ex
The list below covers the statements that most often backfire. For each one, there is a version to avoid and a calmer way to handle the same situation. The goal is not to be fake. It is to protect yourself and your children while the legal process runs its course.
1. Threats to take the kids or cut off access
Saying “You’ll never see the kids again” or “I’m taking them and you can’t stop me” is one of the most damaging things you can put in writing. It signals to a court that you may not support the child’s relationship with the other parent, which judges weigh heavily.
Them: “I want them this weekend.”
Don’t say: “Over my dead body. Good luck ever seeing them again.”
Say instead: “This weekend doesn’t work with our current schedule. Can we look at the calendar and find times that do?”
2. Insults and name-calling
Calling your ex names, mocking them, or attacking their character reads badly in every context. Even if they started it, the person who responds with insults gives the other side something to screenshot.
3. Admissions about drinking, drug use, or losing control
Messages like “I was so wasted I don’t even remember” or “I lost it and punched the wall” can be used against you, especially in a custody dispute. Family Code Section 3011 allows a court to consider a parent’s habitual or continual use of alcohol or controlled substances. Do not hand the other side a written admission.
4. Badmouthing their other parent to or in front of the children
Never say things through your children like “Tell your father he’s a liar” or “Your mom is the reason we’re broke.” Using kids as messengers or venting to them about the other parent damages them and reflects poorly on you if it surfaces in mediation or court.
5. “I’m not paying you a dime”
Threats to withhold child support or spousal support are both unwise and, in the case of court-ordered support, unenforceable as a threat. Support obligations are set by law and court order, not by whoever is angrier in the moment. Refusing to pay ordered support can carry serious legal consequences.
6. Taking the bait during high-conflict exchanges
If your ex is provoking you, the worst thing you can do is match their energy. A long, furious reply gives them exactly what they may be looking for. In high-conflict situations, especially those involving a narcissistic spouse, restraint is a strategy, not a weakness.
Them: “You were always a terrible partner and everyone knows it.”
Don’t say: “You want to talk about terrible? Let me remind you of everything you did.”
Say instead: Nothing about the insult. Respond only to any practical question, or do not respond at all.
7. Provoking them about new relationships or money
Bringing up a new partner to hurt them, or bragging about a purchase to imply you are hiding money, invites conflict and can raise questions about finances during divorce. Keep new relationships and financial details out of your messages with your ex.
8. Side agreements you won’t put in writing
Saying “Let’s just handle support ourselves, no need to make it official” can leave you unprotected. Verbal deals about money or parenting time are hard to enforce and easy to dispute later. If you agree on something important, it belongs in a written, court-recognized document.
9. Anything you wouldn’t want a judge to read
This is the simplest filter. Before you hit send, ask whether you would be comfortable with a family court judge reading the message out loud. If the answer is no, do not send it.
10. Using the children as leverage
Statements like “You can see them when you pay me” tie the children to money or to winning an argument. Courts strongly disfavor a parent who treats parenting time as a bargaining chip. Keep custody and support in separate lanes.
What Not to Say to Your Ex During Divorce
During the divorce itself, avoid saying anything that admits to hiding assets, giving up rights, or agreeing to terms you have not thought through. Comments like “Fine, take the house, I don’t care” or “I’ve got money you’ll never find” can come back to hurt you in settlement.
Because California divides community property under California Family Code Section 2550, casual statements about who “deserves” what carry no legal weight, but statements suggesting you are concealing property can trigger real scrutiny. Do not make promises about the settlement directly to your ex either. Let those conversations happen through your attorneys or in mediation, where they can be documented properly.
It is also wise to avoid rehashing who was at fault for the marriage ending. No-fault law means those arguments rarely change the outcome, and they tend to escalate conflict at exactly the moment you need cooperation.
What Not to Say to Your Ex in Child Custody Mediation
In child custody mediation, avoid attacks on the other parent’s character, absolute demands, and anything that makes you look unwilling to cooperate. Mediation works best when both parents focus on the parenting plan rather than relitigating the relationship.
Custody mediation is a facilitated negotiation about parenting time, decision-making, holidays, and communication. Statements like “I’ll never agree to 50/50” or “You were a useless parent and always will be” stall the process and can push everyone straight back toward litigation. A parent who arrives ready to problem-solve tends to get better results than one who arrives ready to fight.
There is real skill in approaching these sessions strategically. The firm’s guide to the do’s and don’ts of custody mediation breaks down how to prepare and how to keep the conversation productive. If your case involves genuine safety concerns, abuse, or a severe power imbalance, mediation may not be the right tool, and working with a child custody mediation attorney in Los Angeles and Orange County can help you understand your options.
What Not to Say to Your Ex About Child Support and Alimony
When it comes to child support and alimony, do not threaten to withhold payment, do not offer to pay “under the table,” and do not tell your ex you will quit your job to lower your obligation. Each of these can create legal problems or make you look like you are acting in bad faith.
In California, child support is calculated using a statewide guideline formula based largely on each parent’s income and the amount of time each parent spends with the child. Saying “I’ll just work less so I owe you nothing” can backfire, because a court has the authority to base support on earning capacity rather than actual income when a parent is deliberately underemployed.
Spousal support, often called alimony, follows its own framework under California Family Code Section 4320. Casual promises like “I’ll take care of you forever, don’t worry about the paperwork” are not enforceable the way a court order is. Keep support conversations factual, and route the actual terms through your attorney or the court.
What Not to Say to Your Ex After Divorce
After the divorce is final, the main thing not to say is anything that reopens old wounds or undermines your co-parenting relationship. Comments like “The judge got it wrong and I’m going to fix it” or constant reminders of past grievances keep both of you stuck.
If your circumstances genuinely change, such as a job loss, a move, or a shift in the children’s needs, you may be able to request a modification of custody or support. But that happens through a formal request to the court, not through threats or arguments with your ex. Announcing “I’m changing the schedule whether you like it or not” only creates conflict and can weaken your position.
For co-parents, the healthiest messages after divorce are short, factual, and focused on the children. Save the emotional processing for a therapist, a friend, or a support group, not for your ex.
How to Communicate With Your Ex Without Making Things Worse
The safest approach to communicating with your ex is to keep messages brief, informative, friendly, and firm. This is sometimes called the BIFF method, and it works because it removes the emotional hooks that fuel conflict.
A few practical rules help:
- Keep it about logistics. Schedules, exchanges, school, and health. Nothing else.
- Wait before sending anything written in anger. Draft it, then reread it an hour later.
- Assume a judge will read it. That single filter prevents most damaging messages.
- Use a parenting app or email for a written record when conflict is high.
- Do not respond to insults or bait. Answer only the practical question, if there is one.
When communication keeps breaking down, or when your ex uses every exchange to provoke you, it may be time to route communication through counsel. An attorney experienced in high-conflict divorce in Los Angeles and Orange County can help you set boundaries and protect your position.
When to Talk to a Family Law Attorney
What you say to your ex can protect you or expose you, and in the middle of an emotional separation it is genuinely hard to know where that line falls. The core rule is simple: stay calm, stay factual, and never put anything in writing that you would not want a judge to read.
If you are facing divorce, a custody dispute, or ongoing conflict with a difficult ex, speaking with a knowledgeable family law attorney can help you understand how your communication affects your case.
