Most people assume adultery is just something that hurts feelings. But in Pennsylvania, it can actually change how your divorce plays out. Seriously. The state still allows fault-based divorces, which means cheating matters legally, not just emotionally.
Here’s the deal. Pennsylvania is one of the states where you can file for divorce because your spouse cheated. But it gets more complicated than that. Let’s break down exactly what you need to know.
What Is Adultery Under Pennsylvania Law?
Under Pennsylvania law, adultery means having sexual intercourse with someone who isn’t your spouse. Yep, that’s the legal definition. It’s pretty straightforward.
Not sure what counts as adultery? The law is specific. Emotional affairs don’t count. Flirting doesn’t count. Even sexting doesn’t legally qualify. It has to be actual sexual intercourse with another person while you’re still legally married.
Here’s something that surprises people. Even if you’re separated from your spouse, adultery still counts. As long as you’re legally married and haven’t finalized your divorce, having sex with someone else can be considered adultery in Pennsylvania.
Is Adultery a Crime in Pennsylvania?
No. Adultery hasn’t been a crime in Pennsylvania since 1973.
Some states still have criminal adultery laws on the books. But Pennsylvania got rid of those decades ago. You won’t face criminal charges, fines, or jail time just for cheating on your spouse.
That said, adultery is still very much a civil matter. It can affect your divorce in significant ways. Think of it like this: it’s not illegal, but it’s not irrelevant either.
Filing for Divorce Based on Adultery
Pennsylvania allows both no-fault and fault-based divorces. Hold on, this part is important.
A no-fault divorce means you don’t have to prove anyone did anything wrong. You just say the marriage is broken beyond repair. Most people go this route because it’s simpler and cheaper.
But you can also file for a fault-based divorce. Adultery is one of six fault grounds recognized in Pennsylvania under 23 Pa. C.S. § 3301(a)(2). The others include desertion, cruel treatment, bigamy, imprisonment, and indignities that make life unbearable.
What You Need to Prove
Wondering if this applies to you? If you want to file for divorce based on adultery, you have to actually prove it happened. The burden of proof is on you.
Pennsylvania courts require what’s called “clear and convincing evidence.” Basically, you need solid proof that would convince a judge that adultery occurred. This can include:
Text messages showing inappropriate relationships. Hotel receipts or credit card statements. Photos or videos. Witness testimony from people who saw the affair. Admission from the cheating spouse or their partner.
Circumstantial evidence can work too. Repeated unexplained absences, late nights, or suspicious behavior can help build your case. But you’ll need more than just a gut feeling or suspicion.
The “Clean Hands” Requirement
Here’s where it gets tricky. You can only file for a fault-based divorce on adultery grounds if you have what lawyers call “clean hands.” This means you can’t have also committed adultery yourself.
If both spouses cheated, neither one can use adultery as a fault ground for divorce. The court won’t let you point fingers when you’re both guilty. Makes sense, right?
There’s another catch. If you forgave your spouse after finding out about the affair and continued living together as a married couple, you can’t later use that adultery as grounds for divorce. The legal term is “condonation,” which basically means forgiveness.
How Adultery Affects Alimony
Okay, this is where adultery really matters. Adultery can have a big impact on alimony decisions in Pennsylvania.
Pennsylvania law specifically allows judges to consider marital misconduct when deciding on alimony. That’s covered in 23 Pa. C.S. § 3701(b)(14). Adultery counts as marital misconduct.
A judge can reduce or completely deny alimony to a spouse who committed adultery. This is especially true if the affair caused financial or emotional harm to the innocent spouse.
When Adultery Affects Alimony Most
You’re gonna love this one. Adultery hits hardest in alimony cases when the cheating spouse spent marital money on the affair.
Let’s say your spouse bought expensive gifts for their lover. Or paid for hotel rooms and romantic getaways. Or gave them financial support. All of that came out of marital assets that should have belonged to both of you.
In cases like this, judges often reduce or deny alimony to the cheating spouse. They might also adjust the property division to compensate the innocent spouse for money that was wasted on the affair.
Important Timing Rule
Here’s something most people don’t realize. Adultery only counts if it happened before the couple permanently separated.
Once you and your spouse are officially separated, having a relationship with someone else doesn’t legally count as adultery for alimony purposes. Post-separation relationships won’t affect alimony decisions the same way.
But wait, there’s more to know. If you start living with a new partner before or after your divorce, that can affect alimony. Pennsylvania law prohibits alimony to a spouse who cohabits with someone of the opposite sex in a relationship marked by financial, social, and sexual interdependence.
Does Adultery Affect Property Division?
Honestly, not really. Pennsylvania law specifically prohibits judges from considering marital misconduct when dividing property.
The state uses what’s called “equitable distribution.” That means the court divides marital property in a way that’s fair, but not necessarily equal. Judges look at things like income, contributions to the marriage, and future financial needs.
According to 23 Pa. C.S. § 3502, fault isn’t part of that equation. So whether someone cheated or not doesn’t directly affect who gets what in terms of property.
The Exception
There is one exception. If the cheating spouse spent significant marital money on the affair, the court might consider that when dividing assets.
For example, if one spouse drained the savings account to support their affair partner, the judge might give the innocent spouse a larger share of what’s left. This isn’t really about punishing adultery though. It’s about compensating the innocent spouse for money that was improperly spent.
Adultery and Child Custody
Most people assume adultery affects custody. It usually doesn’t.
Pennsylvania courts base custody decisions on the best interests of the child. That’s outlined in 23 Pa. C.S. § 5328. The law lists specific factors judges must consider, and adultery isn’t one of them.
The fact that a parent had an affair doesn’t make them a bad parent. Kids need relationships with both parents, and courts recognize that.
When It Might Matter
Sound complicated? It’s actually not. Adultery only affects custody if the affair somehow harmed the child or raised serious concerns about the parent’s judgment.
For instance, if a parent neglected their child because they were having an affair, that’s a problem. If they left kids unattended to meet up with their lover, that could affect custody. If they exposed the child to inappropriate situations or people, judges will take notice.
But adultery alone, without any direct impact on the children, won’t change custody arrangements. The court cares about parenting ability, not marital fidelity.
Child Support
Child support is separate from everything else. Adultery doesn’t affect it at all.
Pennsylvania calculates child support using a state formula. It’s based on both parents’ incomes and the needs of the child. Marital misconduct isn’t part of the calculation.
You could be the spouse who cheated, or you could be the innocent spouse. Either way, child support will be the same. The law focuses on what’s best for the kids, not who did what wrong in the marriage.
Should You File a Fault-Based Divorce?
Here’s the million-dollar question. Should you actually file for divorce based on adultery?
Most people in Pennsylvania don’t. Less than 2% of divorces are filed on adultery grounds. There’s a reason for that.
Fault-based divorces cost more money. They take more time. And they require more evidence. You’ll probably need to hire a lawyer, gather proof, and possibly go to trial. That adds up fast.
When It Makes Sense
Okay, pause. Read this carefully. A fault-based divorce on adultery grounds might make sense in a few situations.
If you’re seeking alimony and want to prevent your cheating spouse from getting it. If your spouse spent significant marital money on the affair and you want compensation. If you belong to a religious community where a fault-based divorce matters socially. If you just want official acknowledgment that your spouse was at fault.
But for most people, a no-fault divorce is simpler, cheaper, and less emotionally draining. You can still get a divorce. You can still divide property fairly. You just don’t have to prove wrongdoing.
The Two Types of No-Fault Divorce
Now, here’s where things get interesting. Pennsylvania offers two kinds of no-fault divorce.
The first is mutual consent divorce. Both spouses agree that the marriage is irretrievably broken. You file affidavits saying you both consent. After 90 days, the divorce can be granted. This is the fastest option if both people agree.
The second is separation-based divorce. You live apart for at least one year. After that year, either spouse can file for divorce even if the other one doesn’t want it. You just need to prove you’ve been separated for a year.
Many people choose separation-based divorce when adultery is involved. It gives you a clear path to divorce without the hassle of proving the affair in court.
How to Prove Adultery
Not sure what counts as evidence? Let me break it down.
Direct evidence is best. This includes things like admission from the cheating spouse, photos or videos of them with their affair partner, or eyewitness testimony from someone who actually saw them together.
But most cases rely on circumstantial evidence. This might include text messages, emails, phone records showing constant communication, credit card statements for hotels or restaurants, social media posts, or GPS data showing locations.
One important note. You can’t break the law to get evidence. Hacking into your spouse’s email or phone is illegal. Evidence obtained illegally generally can’t be used in court, and you could face criminal charges yourself.
Defenses to Adultery Claims
Wait, it gets better. Even if adultery happened, there are legal defenses that might prevent it from being used as grounds for divorce.
Condonation means you forgave your spouse. If you found out about the affair and continued living together as a married couple, you’ve essentially forgiven them. You can’t later use that same affair against them.
Connivance means you encouraged or helped facilitate the affair. If you pushed your spouse into the relationship or set up opportunities for them to cheat, you can’t claim adultery.
Recrimination means you also committed adultery. As we mentioned earlier, you need clean hands to file on adultery grounds.
What About Prenuptial Agreements?
Some couples have prenuptial agreements that specifically address adultery. These are sometimes called “infidelity clauses.”
An infidelity clause might say that if one spouse commits adultery, they forfeit their right to alimony. Or they might receive a smaller share of marital property. These clauses can be enforced in Pennsylvania, as long as they’re fair and were properly executed.
If you have a prenup with an infidelity clause, that can override some of the general rules about how adultery affects divorce. The agreement you signed becomes the roadmap for what happens.
The Cost of Fault-Based Divorce
Let’s talk money. A fault-based divorce based on adultery typically costs more than a no-fault divorce.
You’ll likely need to hire an attorney. Legal fees for contested divorces can range from $5,000 to $20,000 or more, depending on how complex the case is and how much your spouse fights it.
You might need to hire a private investigator to gather evidence. That can cost anywhere from $1,000 to $10,000. You may need to pay for expert witnesses or forensic accountants if marital assets were misused.
Plus, fault-based divorces take longer. More time in court means more attorney fees. More stress. More conflict.
Steps to Take If Your Spouse Cheated
Here’s what you need to do if you discover your spouse has been unfaithful and you’re considering divorce.
First, gather evidence immediately. Save text messages, emails, and any other documentation. Don’t confront your spouse yet, as they might delete evidence.
Second, consult with a family law attorney. Most offer free initial consultations. They can help you understand your options and whether filing on adultery grounds makes sense for your situation.
Third, protect your finances. Make sure your spouse can’t drain bank accounts or hide assets. You might need to open a separate bank account and redirect your paycheck.
Fourth, document everything. Keep a journal of dates, times, and suspicious activities. Save receipts and financial records. The more documentation you have, the better.
Finally, consider your goals. Do you want the divorce finalized quickly? Are you seeking alimony? Do you need to prove fault for personal or religious reasons? Your goals will determine your strategy.
Common Myths About Adultery in Pennsylvania
You’re not alone, this confuses a lot of people. Let’s clear up some misconceptions.
Myth: If my spouse cheats, I automatically get everything in the divorce. Not true. Adultery doesn’t guarantee you’ll get more property or custody. It only affects alimony in most cases.
Myth: Emotional affairs count as adultery. Nope. Pennsylvania law requires actual sexual intercourse. Emotional connections, no matter how inappropriate, don’t meet the legal definition.
Myth: I can sue my spouse’s lover for breaking up my marriage. Not in Pennsylvania. Only seven states still allow “homewrecker” lawsuits. Pennsylvania isn’t one of them.
Myth: Once we’re separated, adultery doesn’t matter. Sort of true. Post-separation adultery doesn’t affect alimony decisions the same way, but cohabitation with a new partner can still matter.
No-Fault vs. Fault: Which Is Better?
Trust me, this works. For most people going through a divorce in Pennsylvania, no-fault is the way to go.
No-fault divorces are faster, cheaper, and less emotionally draining. You don’t have to prove your spouse did anything wrong. You don’t have to air your dirty laundry in court. You just agree the marriage is over and move forward.
Fault-based divorces make sense in specific situations. If your spouse wasted marital assets on an affair, you might recover that money. If you’re trying to avoid paying alimony to a cheating spouse, proving adultery could help. If you need moral validation that you weren’t at fault, a fault divorce provides that.
But honestly, most people find that the extra cost and stress of a fault-based divorce isn’t worth it. The emotional toll of going through all the evidence and reliving the betrayal can be brutal.
How Long Does a Divorce Take?
Pretty straightforward. The timeline depends on which type of divorce you file.
A mutual consent no-fault divorce can be done in about 90 days if both spouses cooperate. That’s the fastest option available.
A separation-based no-fault divorce requires you to live apart for at least one year first. Then the divorce process itself can take several months.
A fault-based divorce on adultery grounds can take anywhere from six months to several years. It depends on how contested the case is, how much evidence needs to be gathered, and whether you go to trial.
Finding the Right Attorney
Don’t worry, we’ll break it down step by step. If you’re considering divorce and adultery is involved, you need an experienced family law attorney.
Look for someone who specializes in divorce and family law, not general practice. They should have experience handling fault-based divorces if that’s the route you’re considering.
Ask about their fee structure upfront. Most divorce attorneys charge by the hour, with rates ranging from $200 to $500 per hour or more. Some require a retainer, which is money you pay upfront.
During your initial consultation, ask specific questions. How many adultery cases have they handled? What’s their success rate? What strategy would they recommend for your situation? Do they think filing on adultery grounds is worth it?
Trust your gut. You’ll be working closely with this person during a difficult time. You need someone you feel comfortable with and who communicates clearly.
The Emotional Side of Adultery
Let’s be real for a second. Discovering your spouse has been unfaithful is devastating. The legal aspects of adultery and divorce are important, but they’re not the whole story.
You might feel angry, betrayed, heartbroken, or all of the above. That’s completely normal. Many people benefit from therapy or counseling during this time. It can help you process your emotions and make clear-headed decisions about your divorce.
Consider joining a support group for people going through divorce. Talking to others who understand what you’re going through can be incredibly helpful. You’ll realize you’re not alone, and you’ll learn coping strategies from people who’ve been there.
Don’t make major decisions when you’re in an emotional state. Take time to think things through. Consult with professionals. Consider your long-term financial and emotional wellbeing, not just immediate feelings of anger or revenge.
Protecting Yourself During the Process
Here’s where it gets serious. Once you’ve decided to pursue a divorce, protect yourself legally and financially.
Don’t move out of the marital home without talking to a lawyer first. In some cases, moving out can affect your rights to the property or custody of your children.
Don’t hide assets or spend marital money recklessly. Courts take a dim view of this behavior, and it can hurt your case. Be transparent about finances.
Keep communication with your spouse civil and limited. Don’t admit fault for anything. Don’t make threats. Everything you say or write can potentially be used against you later.
Document any harassment, threats, or abusive behavior from your spouse. If you feel unsafe, get a protection from abuse order. Your safety comes first.
Life After Divorce
Now you know the basics. Once your divorce is final, you can move forward with your life.
If you’re awarded alimony, make sure the payment arrangement is clearly spelled out in the divorce decree. If you’re ordered to pay alimony, understand the terms and make payments on time. Failure to pay can result in contempt of court.
If you have children, follow the custody and visitation schedule. Put your kids’ needs first, even if you’re angry at your ex-spouse. Co-parenting successfully requires setting aside personal feelings.
Take time to heal emotionally before jumping into a new relationship. Process what happened in your marriage. Figure out what you want and need going forward. Work on yourself.
Consider updating your will, beneficiary designations on insurance policies and retirement accounts, and other legal documents. Your divorce decree might require you to maintain certain benefits for your ex-spouse or children.

No, adultery is not a crime in Pennsylvania. The state decriminalized it in 1973. However, it can still affect divorce proceedings, particularly alimony decisions.
Can I file for divorce immediately after discovering adultery?
Yes, you can file for divorce right away. However, proving adultery requires clear and convincing evidence, which might take time to gather. Consult with an attorney before filing to make sure you have a strong case.
Will my spouse automatically lose alimony rights if they cheated?
Not automatically. The judge has discretion to consider adultery as marital misconduct when deciding on alimony. It can reduce or eliminate alimony, but it’s not guaranteed. Other factors like income, health, and length of marriage also matter.
Does emotional cheating count as adultery in Pennsylvania?
No. Pennsylvania law defines adultery specifically as sexual intercourse with someone other than your spouse. Emotional affairs, while hurtful, don’t meet the legal definition of adultery.

No. Pennsylvania does not allow lawsuits for alienation of affection or criminal conversation. You can’t sue your spouse’s affair partner for breaking up your marriage. Only seven states still allow these types of lawsuits.
How much does it cost to hire a private investigator to prove adultery?
Private investigators typically charge between $75 to $200 per hour. Total costs can range from $1,000 to $10,000 depending on how long the investigation takes and what evidence needs to be gathered.
If we’re separated but not divorced, is it still adultery if I date someone else?
Yes. As long as you’re legally married, having sexual intercourse with someone other than your spouse can be considered adultery in Pennsylvania. This applies even during separation.
Will adultery affect my child support payments?
No. Pennsylvania calculates child support based on both parents’ incomes and the needs of the child. Marital misconduct like adultery doesn’t factor into child support calculations.
Can I use text messages as evidence of adultery?
Yes, text messages can be used as evidence if they clearly show an inappropriate sexual relationship. However, you can’t illegally obtain them by hacking into your spouse’s phone. The messages must be legally accessible to you.
What if my spouse and I both cheated?
If both spouses committed adultery, neither can use it as a fault ground for divorce. This is called “recrimination.” You would need to file for a no-fault divorce instead.
Final Thoughts
Adultery in Pennsylvania is more than just a personal betrayal. It’s a legal matter that can affect your divorce, especially when it comes to alimony.
