When a spouse cheats, the hurt is real. It is natural to want the law to answer back. Many people ask the same questions. Can I sue the person my spouse cheated with? Will my spouse pay for this in the divorce? Does it change who gets the kids?
The short answer is that adultery matters, but usually not in the ways people expect. New Jersey does not punish cheating the way many people hope. But there are still times when an affair can change a divorce, especially when money, a prenuptial agreement, or a child’s well-being is involved. This post explains how it works.
The Short Answer: Adultery Matters Less Than Most People Expect
In New Jersey, adultery is a legal ground for divorce. It does not automatically change who gets what. Courts focus on fairness and practical facts, like income, the length of the marriage, and a child’s needs, not on punishing bad behavior.
New Jersey Is a No-Fault State
New Jersey lets couples divorce without blaming anyone. The no-fault ground is irreconcilable differences, which generally means problems have caused the marriage to break down for at least six months. Neither spouse has to prove the other did something wrong.
The law also keeps fault grounds. Under N.J.S.A. 2A:34-2, adultery is one of them. So if your spouse had an affair, you can choose to file on that ground, or you can file on the no-fault ground and still deal with the affair when it affects other parts of the case.
Suing Your Spouse’s Affair Partner in New Jersey
Many people see news stories about lawsuits against the “other man” or “other woman” and wonder whether the same could happen here.
New Jersey Has No Homewrecker Law
A few states still allow a spouse to sue a third party for interfering in a marriage. These are often called alienation of affection claims. New Jersey does not. These so-called heart balm claims were ended decades ago through a law passed in 1935, which also stopped lawsuits over broken promises to marry.
That means you cannot sue your spouse’s affair partner in New Jersey for ruining your marriage, no matter how hurt or betrayed you feel. A divorce is generally your remedy.
What Happens If You Name the Other Person in the Divorce
If you file for divorce on the ground of adultery, the person your spouse had the affair with is usually named in the paperwork, if you know who it is. If you do not know the name, you generally describe the person and the time, place, and details of the events. That person is then given the right to respond to your claims.
Even when the person is named, they cannot be ordered to pay you. The court can decide issues between you and your spouse, but it cannot make a third party financially responsible for the end of your marriage.
Filing for Divorce on the Grounds of Adultery
Filing on adultery is allowed, but it has costs. It helps to understand what it takes before you decide.
What You Have to Prove
If you file on this ground, you have to prove the affair. Evidence can include text messages, emails, photos, and testimony from witnesses. Direct proof is not always easy to find, and even strong proof may not change how a judge handles property, alimony, or custody.
Be careful about how you get evidence. Do not hack your spouse’s phone, email, or accounts, or put tracking devices on their car or phone. That can create legal trouble for you. A lawyer can tell you how to get the proof the right way, such as through the formal process of exchanging information during the case.
Why Many People Choose No-Fault Instead
Proving adultery can add time, cost, and conflict to a divorce. A no-fault filing is often faster and less stressful. It keeps the focus on ending the marriage and settling the practical issues, and it can keep the details of an affair out of court records.
Choosing no-fault does not mean letting your spouse off the hook. If marital money was spent on the affair, or if another issue comes up that your spouse’s conduct affects, you can still raise it in a no-fault case.
How Adultery Can Affect the Money Side of Divorce
Most people expect an affair to change the money. In New Jersey, the effect is smaller than expected, with one key exception.
Property Division
New Jersey follows equitable distribution. That means marital property is divided in a way that is fair, but not necessarily equal. The court looks at things like the length of the marriage, each spouse’s income and contributions, and what each person needs going forward. These factors are listed in N.J.S.A. 2A:34-23.1.
Adultery by itself usually does not change how property is divided. A judge is dividing assets, not assigning blame.
When Money Spent on an Affair Matters
Here is where an affair can matter. If your spouse spent marital money on the affair, such as gifts, trips, hotel stays, or dinners, the court can treat that as dissipation of marital assets. In plain words, one spouse used shared money for a purpose that had nothing to do with the marriage.
When a court finds this, it may give the other spouse a larger share of what is left, or adjust alimony, to make up for the loss. Records are key. Bank statements, credit card bills, and receipts showing the spending can help prove it. You generally do not get the exact dollars back. Instead, the court accounts for the loss when it divides property.
Alimony
Alimony, or spousal support, is based on factors in N.J.S.A. 2A:34-23. These include each spouse’s income and needs, the standard of living during the marriage, and the length of the marriage. Adultery is not on that list, and a spouse who cheated is not automatically barred from receiving support.
Fault can matter in rare cases, such as extreme misconduct or serious financial wrongdoing. Spending marital money on an affair can also affect the numbers. And if a spouse who receives alimony moves in with a new partner, New Jersey law lets the court consider lowering or ending that support, but the court will want evidence of the living arrangement first.
Prenuptial Agreements and Infidelity Clauses
Some prenuptial agreements include a clause about cheating. For example, a spouse who has an affair might give up the right to alimony or certain assets. If your agreement has a clause like this, expect your spouse to point to it. It can also be used as leverage in settlement talks. A lawyer can review the wording to see whether it is clear and whether a court is likely to enforce it.
Adultery and Child Custody
Custody is decided based on the best interests of the child. A parent’s affair usually does not change that on its own. A judge wants to know about each parent’s ability to care for the child, the child’s relationship with each parent, and whether each parent can provide a stable, safe home.
An affair can matter if it directly hurt the child. For example, if a parent exposed the child to unsafe situations or neglected the child’s care because of the affair, the court may take that into account. But being unfaithful does not make someone an unfit parent.
Marital Tort Claims for a Sexually Transmitted Disease
There is one situation where cheating can lead to a separate claim for money. New Jersey courts recognize marital tort claims for negligently passing on a sexually transmitted disease, such as herpes, HIV, gonorrhea, or chlamydia. These claims are often called Tevis claims.
They usually involve a spouse who had an affair, caught an infection, and passed it to the other spouse without disclosing it. If this happened to you, tell your lawyer. There is no reason to feel ashamed, and an attorney will treat the information seriously and keep it confidential. A lawyer can advise you on whether a claim for money damages makes sense alongside the divorce.
The Emotional Side of Divorce After an Affair
The legal rules may be less harsh than people expect, but the emotional toll is real.
How Emotions Can Affect Negotiations
Betrayal, anger, and sadness can make it hard for spouses to work together. When couples cannot agree on issues like alimony or custody, a judge has to decide, which can make the case longer and more stressful. Keeping emotions in check and focusing on your goals can help you avoid costly fights that do not change the outcome.
Mediation
Mediation lets spouses meet with a neutral third party to work out issues like alimony, custody, and property. It can keep the details of an affair private and give spouses a less formal place to talk. It is not right for every couple. It may not work if one spouse refuses to cooperate or if there is a big power imbalance.
Steps to Take if Your Spouse Cheated
- Take time before making big decisions, since choices made in anger can be hard to undo
- Gather evidence the right way, and avoid hacking or tracking
- Save bank statements, credit card bills, and receipts that show spending on the affair
- Keep your children out of the conflict
- Do not move out or sign anything before talking to a lawyer
- Talk to a family law attorney about whether to file on adultery or no-fault
- Lean on friends, family, or a counselor for support
Moving Forward After Divorce
Divorce after an affair is painful, but people do rebuild. Whether you file on adultery or choose no-fault, the best path is usually the one that protects your finances, your children, and your peace of mind. Taking care of your legal and emotional needs now can help you start the next chapter with confidence.
