Adultery Laws in Alabama (2026): Still Illegal and Still Complicated

Most people assume adultery is just a personal matter. Something between two people and maybe a therapist. But in Alabama, it’s actually against the law. Yep, you read that right.

If you’re going through a divorce or just want to know where you stand legally, this guide breaks it all down. No legal jargon. No confusing lingo. Just the facts, plain and simple.

What Is Adultery Under Alabama Law?

Adultery in Alabama has a very specific legal definition. It’s not just cheating on your spouse. The law goes a step further.

Under Alabama Code Section 13A-13-2, adultery happens when a married person has sexual intercourse with someone who is not their spouse AND lives with that person. Both things have to be true. The affair AND the cohabitation. So a one-night stand, legally speaking, may not meet the full definition under the criminal statute. This part surprises a lot of people.

The law also applies if either person in the relationship is married. It doesn’t have to be both. If you’re single but sleeping with and living with a married person, you could also be breaking the law.

Is Adultery Actually a Crime in Alabama?

Short answer: yes. Technically, it is.

Alabama classifies adultery as a Class B misdemeanor. That’s the same category as certain assault charges and some theft crimes. It’s not a tiny infraction. A Class B misdemeanor in Alabama can carry up to six months in jail and a fine of up to $3,000.

Now, here’s where it gets interesting. While the law exists, prosecutors almost never enforce it. Honestly, it’s rare to find a case where someone was actually arrested and prosecuted for adultery in recent years. But rare doesn’t mean impossible. The law is still on the books, and it could technically be enforced at any time.

Think of it like a traffic law that’s rarely ticketed but can still get you pulled over. It exists. It has consequences. And you should know about it.

Alabama Is One of Only a Few States That Still Criminalizes It

Most of the country has moved on from criminalizing adultery. But Alabama has not. As of 2026, only a handful of states still have adultery on the criminal books. Alabama is one of them, treating it as a misdemeanor offense. Three states actually classify adultery as a felony. Alabama’s version is less severe, but it’s still legally significant.

You’re not alone in being surprised by this. Most people don’t realize how strict these laws are until they’re already in a situation that involves them.

The Cohabitation Requirement Matters a Lot

Okay, pause. Read this carefully because this part is critical.

The criminal statute in Alabama requires both sexual intercourse AND cohabitation. Cohabitation means living together. If two people are having an affair but living in separate homes, the criminal portion of the law may not apply to them. Alabama courts have interpreted the statute this way based on how the law is written.

This is different from how adultery works in a divorce case. In divorce court, the standard is different. Courts can consider extramarital affairs even without cohabitation when deciding things like alimony and property.

So the criminal law and the divorce law are not identical. They overlap, but they’re not the same. Pretty nuanced, right?

How Adultery Affects Divorce in Alabama

Here’s where things really matter for most people. Even if adultery is never criminally charged, it can still have a major impact on your divorce case.

Alabama allows both no-fault and fault-based divorces. In a no-fault divorce, neither spouse has to prove the other did anything wrong. You just say the marriage is irretrievably broken. Fast, simpler, fewer headaches. But in a fault-based divorce, you can cite specific reasons. Adultery is one of those reasons.

If you go the fault-based route, you need actual evidence. The courts require clear and convincing proof. Rumors, suspicions, and gut feelings won’t cut it. Courts want things like text messages, emails, financial records showing money spent on an affair partner, or other concrete documentation.

Adultery and Alimony: This Is the Big One

Honestly, this is the part most people care about most. And for good reason.

Under Alabama Code Section 30-2-51, a judge can consider a spouse’s adultery when deciding on alimony. This is where the real financial consequences come in. If you cheated and you were hoping to receive alimony after the divorce, a judge can reduce the amount you receive. In some cases, the court can deny alimony altogether if you were the unfaithful spouse.

It works the other way too. If the higher-earning spouse was unfaithful, the court may order them to pay more alimony to the innocent spouse. Alabama courts don’t use alimony to financially destroy someone, but they do factor in the affair, especially if the cheating spouse used joint money to fund the relationship.

Say your spouse spent thousands of dollars on vacations, gifts, or even a car for an affair partner. That money came from your shared finances. Courts can take that into account when dividing assets and calculating support.

Adultery and Property Division

Alabama is an equitable distribution state. That means courts try to divide marital property fairly, not necessarily 50/50. Adultery can shift that balance.

If a judge grants a fault-based divorce because of adultery, they have more flexibility in how they divide assets. The innocent spouse may end up with a larger share of the marital estate. The extent depends on the specifics of the case. How long did the affair last? Were joint funds used? Did the affair partner receive any marital assets?

These details matter. A long-term affair where shared money was spent on the affair partner is treated more seriously than a brief incident. Sound complicated? It can be. That’s why having a lawyer helps.

Adultery and Child Custody

Most people assume cheating automatically means losing custody. That’s not how it works in Alabama. Courts decide custody based on the best interests of the child. Adultery alone is usually not enough to change that standard.

However, if the affair had a direct negative impact on the children, that’s a different story. If a parent exposed their children to an unsafe situation involving an affair partner, or if the affair caused emotional harm to the children, a judge might consider those factors in custody decisions.

Stay with me here. The key word is “impact.” It’s not about judging someone’s personal choices. It’s about how those choices affected the kids.

Defenses to Adultery Charges

Wondering if there’s any way to fight a criminal adultery charge or block adultery from being used as grounds in a divorce? There are a few situations where the law says adultery cannot be used.

First, if you genuinely and reasonably believed you and the other person were both unmarried, that’s a valid defense to the criminal charge. You have to raise this defense yourself, but the prosecution still has to prove you knew someone was married.

In a divorce case, adultery cannot be used as grounds if the innocent spouse consented to or encouraged the affair. It also cannot be used if both spouses committed adultery. That’s called recrimination. Essentially, if both people cheated, neither can use the other’s adultery as a fault ground. There’s also a concept called condonation. If the innocent spouse learned of the affair and then continued in the marriage as normal, the court may decide they forgave the behavior, which can block its use in divorce.

What Evidence Do Courts Look For?

Direct evidence of adultery is rare. Confessions and video footage are uncommon. Courts usually deal with circumstantial evidence. That means evidence that, taken together, strongly suggests the affair happened.

Common types of evidence include phone records, hotel receipts, bank statements showing suspicious purchases, social media messages, witness testimony, and GPS data. Digital forensics has become increasingly important in these cases. Text messages and app conversations can be used in court if they meet authentication requirements.

A friend of mine went through this process. The evidence gathering took months. By the time the case was done, the financial records told the whole story. Details you never thought about, like credit card statements and shared app accounts, became key evidence.

Practical Steps If Adultery Is Part of Your Situation

If you believe your spouse has committed adultery and you’re thinking about filing for divorce, here’s what you should do.

Start documenting everything right away. Save relevant messages, emails, and financial records. Don’t confront your spouse in a way that could destroy evidence. Reach out to a family law attorney before making any big moves. An experienced attorney can help you decide whether filing on fault grounds makes sense for your specific situation.

If you’re the spouse who committed adultery, don’t panic. An experienced attorney can help you understand your options and navigate the process. The outcome isn’t predetermined.

Either way, the legal benefits of filing a fault-based divorce don’t always outweigh the costs. Proving adultery can be expensive, time-consuming, and emotionally exhausting. A good attorney will help you weigh the pros and cons before choosing a path.
