The Kyrsten Sinema Affair Lawsuit – And Why California Is Different
The Sinema “Homewrecker” Lawsuit
In early 2026, former U.S. Senator Kyrsten Sinema was sued by her bodyguard’s wife, who claimed Sinema had an affair with him and “destroyed” their marriage. News outlets called it a “homewrecker” or “alienation of affection” lawsuit, because in some states you can sue the person you believe broke up your marriage.
Stories like this hit a nerve. If you’ve been cheated on, you may feel hurt, furious, and desperate for some kind of justice. It’s natural to wonder whether you can file the same kind of lawsuit in California—either against your spouse’s affair partner or against your spouse directly.
But California Plays by Different Rules
California law takes a very different approach.
Our Civil Code specifically bans these “homewrecker” lawsuits: alienation of affection is not a valid claim here (Civil Code § 43.4, § 43.5). California is also a “no‑fault” divorce state, which means you don’t have to prove adultery to end your marriage (Family Code § 2310), and the court does not award extra money just because someone cheated.
Instead of revenge lawsuits, California focuses on:
- Dividing property and debts
- Setting child support and spousal support
- Making custody and parenting time orders
- Protecting you and your children if there is abuse
That may not match what you wish the law allowed—but there are still real tools you can use to protect your future. This article is general information, not legal advice; always talk with a lawyer about your specific situation.
What Does It Mean to “Sue for Adultery”?
What People Usually Mean
When someone says they want to “sue for adultery,” they usually mean one of two things:
- Suing the affair partner – a “homewrecker” or “alienation of affection” lawsuit, like the one filed against Kyrsten Sinema in another state.
- Suing their own spouse – for the emotional pain, embarrassment, or betrayal caused by cheating.
Both ideas are understandable. But California law does not treat adultery the way many people expect.
How California Law Treats These Claims
In California, traditional “heart‑balm” lawsuits based on affairs have been abolished for decades:
- No suing the homewrecker: Civil Code § 43.4 makes alienation of affection lawsuits invalid here. Civil Code § 43.5 wipes out similar romance‑based claims.
- No separate lawsuit for cheating itself: Because divorce is no‑fault (Family Code § 2310), you don’t need to prove adultery to end your marriage, and you don’t get a bonus for doing so.
California courts are not in the business of putting a price tag on infidelity. Instead, they focus on ending the marriage, dividing property, assigning debts, and setting support and custody orders.
What You Can – and Can’t – Sue For After Cheating in California
The Short Answer
Here’s how California actually handles legal claims around adultery:
- You cannot sue the “homewrecker” for breaking up your marriage.
California abolished “homewrecker” or “alienation of affection” lawsuits. Civil Code § 43.4 and § 43.5 say you cannot sue your spouse’s affair partner just for ruining your relationship. - You usually cannot sue your spouse just for cheating.
Infidelity by itself is not a separate civil lawsuit in California. Under our no‑fault system (Family Code § 2310), the court does not award damages for the emotional harm of adultery. - You can go after community money spent on the affair.
If your spouse used marital funds for hotels, trips, gifts, or rent for the affair, you can ask the court to account for that. Family Code §§ 2550, 2623–2625 allow the court to divide community property and debts and can support reimbursement or an unequal division when one spouse misuses community assets. - Serious misconduct tied to the affair might support another claim.
In rare cases, extreme, outrageous behavior connected to the affair might support a separate civil claim (for example, intentional infliction of emotional distress or abuse). These are unusual, very fact‑specific cases that need careful legal review. - You can always seek a divorce and orders to protect your future.
Even if you can’t “sue for adultery,” you can file for divorce, request custody and parenting time orders, ask for child and spousal support, and seek protective orders if there’s abuse. Those are the real legal tools California gives you to move forward.
If Your Spouse Cheated in California, What Should You Do Next?
Step 1: Focus on Safety and Emotional Support
Your first priority is safety—yours and your children’s.
- Avoid heated confrontations, especially if you’re worried things could turn volatile.
- Have serious talks in public places or with a trusted third person present.
- If there is any threat of violence, call 911 and consider speaking with a domestic violence hotline about safety planning or a restraining order under California’s Domestic Violence Prevention Act.
You don’t have to go through this alone. Lean on close friends, family, support groups, or a therapist so you have emotional backup while you make decisions.
Step 2: Quietly Gather Information and Financial Records
Before making big moves, get organized. Calmly gather documents you can access legally, such as:
- Bank and credit card statements
- Tax returns for the last few years
- Pay stubs and retirement account statements
- Records that show large gifts, trips, or rent tied to the affair
In California, if your spouse spent community money on the affair, you can ask the court for reimbursement or an unequal division of property under Family Code §§ 2550 and 2623–2625. Do not hack accounts, read private journals, or break into devices; that can create legal problems of its own.
Step 3: Talk to a California Family Law Attorney
Instead of trying to “sue for adultery” or go after the “homewrecker” (which Civil Code § 43.4 does not allow), meet with a California family law attorney to talk through your options.
You can discuss:
- Divorce or legal separation under California’s no‑fault system (Family Code § 2310)
- How community property and debts might be divided
- Whether you have reimbursement claims for affair spending
- Temporary orders for custody, parenting time, child support, and spousal support
- Whether a restraining order fits into your overall plan if there is abuse
An early consultation can prevent costly mistakes—like moving out too soon, draining accounts, or sending angry texts that later show up in court.
Step 4: Start Planning Your New Reality
Once you understand your rights, begin mapping out practical next steps:
- Where you and the children will live
- What a realistic weekly parenting schedule could look like
- How you’ll cover rent, food, and basic expenses in the short term
- What you need—financially and emotionally—over the next 6–12 months
The goal is to shift your energy away from punishing the affair and toward protecting your children, your finances, and your future.
Common Legal Myths and Risks After Adultery in California
Myth 1: “I Can Sue the Homewrecker and Make Them Pay”
Headlines about “homewrecker” lawsuits in other states make many Californians think they can do the same thing here. They can’t.
Civil Code § 43.4 abolishes “alienation of affection” claims. That means you cannot sue your spouse’s affair partner just for breaking up your marriage. Filing a lawsuit California law doesn’t allow only drains money and energy you may need for your divorce and your kids.
Myth 2: “If I Prove Cheating, I’ll Win Everything”
California is no‑fault. Under Family Code § 2310, the court does not punish adultery by giving one spouse extra property, more support, or full custody.
Spousal support is based on the factors in Family Code § 4320, such as:
- Length of the marriage
- Each spouse’s income and earning capacity
- Health, age, and documented needs
What can affect the outcome is other misconduct—like domestic violence, hiding assets, or wasting community funds on an affair. Those issues can lead to reimbursement or an unequal division of property under Family Code §§ 2550 and 2623–2625.
Myth 3: “We Can Write Our Own ‘Cheating Penalty’ and It Will Stick”
Some couples sign a DIY agreement that says something like, “If you cheat, you owe me $50,000,” assuming a judge will enforce it.
In Diosdado v. Diosdado, the California Court of Appeal struck down an adultery penalty clause in a marital agreement. The court said it conflicted with California’s no‑fault divorce system. Most “infidelity fines” run into the same problem.
Before you sign anything meant to punish cheating—whether before marriage, during marriage, or during a breakup—talk with a California family law attorney about how a court is likely to treat it.
A California Story: Turning Betrayal Into a Plan, Not a Lawsuit
From “I Want to Sue Her” to “I Want My Life Back”
When “Maria” came into our office, she was shaking with anger. Her husband had been having an affair with a coworker. After seeing national headlines about “homewrecker” lawsuits, she wanted to sue the other woman and “make her pay.”
We walked through California’s rules, including Civil Code § 43.4. No matter how deep the betrayal felt, our courts simply would not let her sue the affair partner for destroying her marriage.
Once we faced that hard truth, we shifted to what she could do:
- We reviewed credit card and bank records and found thousands of dollars in hotel stays, trips, and gifts spent on the affair.
- Using California’s community property and reimbursement rules (Family Code §§ 2550, 2623–2625), we built a plan to seek repayment through the property division.
- At the same time, we focused on stabilizing the kids’ school routine, setting up a realistic parenting schedule, and requesting child and spousal support using the factors in Family Code § 4320.
In the end, Maria didn’t get the “homewrecker” trial she imagined. But she did walk away with more financial security, a clear custody plan, and a sense of control. Focusing on real legal tools—instead of an impossible adultery lawsuit—gave her something more valuable than revenge: a roadmap for her future.

Get Calm, California‑Specific Guidance
When an affair comes to light, it’s tempting to:
- Empty bank accounts
- Move out with the kids overnight
- Fire off angry texts, emails, or social media posts
- Threaten to sue the affair partner
In California, though, you generally cannot sue the affair partner (Civil Code § 43.4), and our no‑fault system (Family Code § 2310) means the court will not “reward” you financially just because your spouse cheated. Acting on anger or on out‑of‑state advice can quietly hurt your property claims, your custody case, and your long‑term stability.

- Community property division and possible reimbursement for affair spending (Family Code §§ 2550, 2623–2625)
- Realistic parenting plans that protect your children’s stability
- Fair child and spousal support based on California’s legal factors
- Safety planning and protective orders when needed
You can talk openly about the affair, your fears, and your goals in a confidential, judgment‑free consultation. We’ll walk you through your options and help you make clear, grounded choices before you take any big steps.
You Can’t Sue for Adultery Here – But You Still Have Rights
Moving Forward After Infidelity in California
The Sinema “homewrecker” headlines have a lot of people wondering if they can do the same thing here in California. The answer is no: California banned “heart‑balm” lawsuits like alienation of affection decades ago (Civil Code §§ 43.4–43.5), and our no‑fault divorce system (Family Code § 2310) means you generally cannot sue your spouse or the affair partner just for cheating.
That doesn’t mean you’re powerless. You can:
- Protect your finances through community property rules and reimbursement claims if marital funds were spent on the affair (Family Code §§ 2550, 2623–2625)
- Ask for custody and parenting orders that put your children’s stability first
- Seek child support, spousal support, and—if necessary—protective orders
Life after infidelity is possible. Informed legal choices can help you move from crisis toward a more secure future.
