Adultery Laws in New York (2026): Big Changes You Should Know
Most people have no idea this changed recently. Seriously. For over a hundred years, adultery was actually a crime in New York. But in November 2024, everything shifted. Let’s break down what happened and what it means for you today.
Here’s the deal. Adultery isn’t a crime anymore in New York. Governor Kathy Hochul signed a bill repealing the old law on November 22, 2024. But that doesn’t mean cheating has zero legal consequences. It just means you won’t get arrested for it.
What Is Adultery in New York?
Adultery happens when a married person has sexual intercourse with someone who isn’t their spouse. Pretty straightforward, right?
The old law defined it super specifically. It meant voluntary sexual intercourse between a married person and someone other than their husband or wife. The law covered vaginal, oral, or anal sex. It had to be voluntary for both people involved.
Now, here’s where people get confused. Emotional affairs don’t count as adultery under the law. Neither do kissing or romantic texting. The legal definition required actual sexual contact. Yep, that specific.
The Old Criminal Law (1907-2024)
For 117 years, adultery was a Class B misdemeanor in New York. The law went into effect in 1907. It was created to make divorces harder to get back when adultery was the only way to legally end a marriage.
What were the penalties? You could face up to 90 days in jail. There was also a $500 fine. Sounds pretty serious for something most people didn’t even know was illegal.
But wait, it gets interesting. Hardly anyone was ever actually prosecuted. Only about 13 people were charged under this law between 1907 and 2024. Just five of those cases resulted in convictions. The last known charge happened in 2010 against a woman caught having sex in a public park. Even that charge got dropped later.
Why was it so rarely enforced? Honestly, it was nearly impossible to prove. You needed solid evidence. Testimony from the cheated spouse didn’t count. You had to have witnesses or really clear proof. Most district attorneys didn’t bother trying to prosecute these cases.
Why New York Repealed the Law
The law was called “silly” and “outdated” by Governor Hochul herself. She’s been married for 40 years, which makes it pretty ironic that she signed this bill. But she said relationships are complex. These matters should be handled privately, not by the criminal justice system.
State lawmakers agreed the law served no real purpose. Assemblyman Charles Lavine wrote the bill to overturn it. He pointed out that millions of people probably committed adultery in New York over those 117 years. But only 13 got arrested. That’s not exactly a deterrent, is it?
The New York State Senate called it what it was. An outdated statute that criminalized sexual behavior between consenting adults. Times have changed since 1907. The law needed to change too.
Some people opposed the repeal. The Catholic League president said keeping the law sent an important signal about marriage. But even the Catholic Church in New York didn’t take an official position against the repeal. They acknowledged that not all sins should be crimes.
Adultery and Divorce Today
Okay, pause. This part is really important. Just because adultery isn’t a crime doesn’t mean it’s irrelevant in divorce court.
You can still file for divorce based on adultery in New York. It remains one of the seven legal grounds for divorce. The other grounds include cruel treatment, abandonment, imprisonment, and something called “irretrievable breakdown” (the no-fault option).
Filing for divorce based on adultery is what lawyers call a “fault-based” divorce. You’re saying your spouse did something wrong that caused the marriage to fail. But you have to prove it. And proving adultery in court is honestly pretty difficult.
What kind of evidence do you need? You can’t just testify yourself about your spouse’s affair. The court won’t accept that. You need witnesses who saw something. Or you need hard evidence like photos, videos, phone records, emails, or text messages.
Most divorce lawyers will tell you something surprising. Filing on adultery grounds usually isn’t worth it. Here’s why.
Why Most People Skip the Adultery Route
First, it makes everything way more expensive. Gathering evidence costs money. Hiring private investigators costs even more. The whole divorce takes longer and gets nastier.
Second, it can backfire emotionally. Your kids might have to hear details about the affair in court. Family members get dragged into testifying. The whole thing becomes public and humiliating for everyone involved.
Third, and this might surprise you, adultery doesn’t automatically change the outcome much. It rarely affects how property gets divided. New York uses “equitable distribution,” which means fair division based on lots of factors. Fault isn’t usually a huge consideration.
Does adultery affect who gets custody of the kids? Not really. Judges focus on what’s best for the children. Being a cheating spouse doesn’t necessarily make you a bad parent. The court looks at actual parenting ability, not marital behavior.
The one exception? If you used marital money to fund your affair, that’s called “marital waste.” The court can offset your share of assets to compensate your spouse. So if you spent $10,000 on hotel rooms and gifts for someone you were cheating with, your spouse might get an extra $5,000 in the divorce settlement.
The No-Fault Alternative
Since 2010, New York has allowed no-fault divorce. You just need to say the marriage has been “irretrievably broken” for at least six months. That’s it. No accusations. No proof required. No finger-pointing.
Most people go this route. It’s faster. It’s cheaper. It’s less emotionally destructive. You can still negotiate a fair settlement without dragging everyone through the mud.
Sound complicated? It’s actually not. The no-fault option lets you focus on moving forward instead of dwelling on what went wrong.
When Adultery Still Matters in Divorce
There are a few situations where filing on adultery grounds might actually make sense. Let’s talk about them.
If your spouse spent tons of marital money on their affair, you might want to pursue a fault-based divorce. This could help you recover some of those funds. But you’ll need receipts, bank statements, credit card records, and other financial proof.
If there’s a pattern of abuse connected to the adultery, that changes things. For example, if your spouse brought their affair partner around your children inappropriately, or if the affair involved domestic violence, the court needs to know.
Some people just need the emotional closure of having the adultery officially recognized. There’s no judgment here. If that’s what you need to move on, talk to a lawyer about whether it’s realistic in your situation.
Defenses Against Adultery Claims
Wondering if this applies to you? If you’re being accused of adultery in a divorce, you have some defenses available.
Forgiveness is one defense. If your spouse knew about the affair and continued the marriage anyway, they can’t later use it as grounds for divorce. Resuming sexual relations after discovering the affair counts as forgiveness.
Another defense is called “condonation.” This means your spouse actually approved of or encouraged the affair. Pretty rare, but it happens.
If you committed adultery but so did your spouse, neither of you can use it as a fault-based ground. You’re both equally at fault, basically.
Also, timing matters. If the affair happened more than five years ago, it’s too late to file for divorce based on that adultery. The law has a statute of limitations on this stuff.
Adultery and Alimony (Spousal Maintenance)
Does cheating affect alimony payments? Sometimes, but probably not how you think.
New York uses a calculator to figure out alimony amounts. It’s based on income, length of marriage, and financial need. Adultery isn’t part of that calculation.
However, a judge has some discretion. If the adultery involved spending significant marital funds, that could affect the alimony decision. If the cheating spouse gave expensive gifts, paid for trips, or set up an apartment for their affair partner, the judge might consider that.
But here’s the truth. In most cases, adultery has minimal impact on alimony. The focus is on financial fairness, not punishment.
How to Handle Adultery in Your Divorce
If you’re dealing with infidelity and thinking about divorce, here’s some practical guidance.
Talk to a lawyer first. Seriously. Before you confront your spouse, before you file anything, get legal advice. A good family law attorney can help you understand whether pursuing a fault-based divorce makes sense.
Gather evidence if you think you might need it. But don’t do anything illegal. Don’t hack into your spouse’s phone or computer. Don’t trespass to take photos. Don’t stalk anyone. That can backfire badly in court.
Consider mediation or collaborative divorce. Even if your spouse cheated, you might be able to work things out privately. This saves money and reduces stress for everyone, especially your kids.
Think about what you really want. Is it punishment? Closure? A fair financial settlement? Figure out your actual goals before deciding how to proceed.
Don’t trash-talk your spouse on social media. Honestly, this is crucial. Everything you post can be used in court. Keep it private and dignified, even when you’re hurting.
Special Circumstances to Know
There are some situations that need extra attention. Let’s cover them quickly.
If you’re in a same-sex marriage, all these rules apply exactly the same way. New York doesn’t distinguish between different types of marriages when it comes to adultery and divorce.
If your spouse is in the military, there might be additional consequences for them beyond the divorce. The military has its own rules about adultery. But that’s their problem, not something the New York courts will handle.
If you signed a prenuptial agreement, check what it says about adultery. Some prenups include clauses about what happens if someone cheats. Those might be enforceable depending on how they’re written.
What About Other States?
New York isn’t alone in ditching its adultery law. Several other states have repealed theirs too in recent years.
But hold on, this one’s important. About 16 states still have laws making adultery a crime as of 2024. In some states like Oklahoma, Wisconsin, and Michigan, it’s even a felony. Literally a serious crime.
If you travel to those states or if your spouse lives elsewhere, different rules might apply. Don’t assume what’s legal in New York is legal everywhere.
Moving Forward After Infidelity
Look, discovering adultery hurts. There’s no way around that. But you have options for how to handle it legally.
You don’t have to make everything a battle. The legal system gives you choices. You can file for divorce based on adultery if you want. Or you can take the no-fault route and skip the drama.
Most experts agree on one thing. Using the divorce to punish your spouse usually doesn’t help anyone. It costs more money. It takes more time. It creates more pain for your whole family.
Trust me, this works better. Focus on getting a fair settlement and moving forward with your life. Leave the past in the past as much as you can.

Can I still get divorced because my spouse cheated? Yes. Adultery remains a valid ground for divorce in New York. But you’ll need strong evidence to prove it, and most lawyers suggest using the no-fault option instead.
Will my spouse lose custody because they had an affair? Probably not. Judges care about parenting ability, not marital fidelity. The affair would only matter if it directly harmed the children or showed extremely poor judgment around them.

What if my spouse forgave me after finding out about the affair? If they continued the marriage and resumed sexual relations after learning about it, they can’t later use that adultery as grounds for divorce. It’s considered forgiven.
Does adultery affect alimony payments? It can, but rarely does. New York uses a formula based on income and need. Adultery only matters if marital money was wasted on the affair.
