aught Your Spouse Cheating? What to Do First

Key Points:

Do not confront your spouse the day you find out. The 48 hours after a confrontation are when accounts get closed, phones get wiped, money moves, and the evidence you could have collected quietly disappears.

Documentation beats detective work. A dated, factual log plus screenshots of things you already have lawful access to will do more for your case than anything you'd get by breaking into a device, and it won't get you sued or arrested.

Illegally obtained evidence is worse than no evidence. Under the federal Wiretap Act, the Stored Communications Act, and state statutes like La. R.S. 14:323, spyware, keyloggers, and GPS trackers expose you to criminal and civil liability, and they hand your spouse a much better story than the one they started with.

The money usually matters more than the affair. Hotel charges, gifts, rent on a second apartment, and cash withdrawals are provable, and in a community property state they can be recovered. Photographs of your spouse with someone else generally can't be turned into a dollar figure.

Adultery changes less than people expect, except where it doesn't. In most states, no-fault divorce means infidelity has little legal weight. In Louisiana, it does two specific things: it gets you an immediate divorce under Civil Code Article 103(2), and under Article 112 it can bar the cheating spouse from receiving final periodic support.

I have practiced family law in Louisiana for more than forty years, and I've had this conversation in my office several hundred times. Someone sits down, puts a phone on my desk, and says some version of: I found out on Tuesday, I haven't slept since, and I don't know what I'm supposed to do.

So let me give you the answer I give them, in the order I give it.

The first thing to understand is that you're in the worst possible condition to make decisions right now, and the decisions available to you in the next two weeks are unusually consequential. That's an unfair combination. The way through it is to do a small number of concrete things and postpone everything else.

Don't Confront Yet

I know this is the hardest instruction in the article, and I know why. You want to know. You want them to admit it. You want the humiliation to stop being yours alone.

Here's what happens when you confront on day one. Your spouse denies it, then goes home and deletes the messages, changes every password, and calls a lawyer. Or they confess, and then they go home and delete the messages, change every password, and call a lawyer. Either way, by Thursday you have a spouse who knows exactly what you know and has had 72 hours to prepare.

Roughly one in five married men and one in eight married women report having had sex with someone other than their spouse, according to the Institute for Family Studies' analysis of General Social Survey data. This is not rare, and none of the people it happens to feel like waiting. Wait anyway. Two weeks of quiet is worth more to your case than any confession you'll extract in an argument.

The exception is safety. If you have any reason to think your spouse will become violent, or if there's a history of it, the calculus changes completely and the priority is a safety plan, not evidence. Talk to a lawyer before you say anything, and if you're in danger, the National Domestic Violence Hotline is at 1-800-799-7233.

What Documenting Actually Means

Most people hear "document it" and think surveillance. It isn't. It's bookkeeping.

Start a log. Not a diary, and not a place to process feelings, because that version will get read aloud in a courtroom someday and it will not help you. A log is dated entries, written the same day, stating what happened in flat language. "March 14. He said he was at a work dinner in Baton Rouge. Amex statement shows a charge at a restaurant on Magazine Street at 8:40 p.m." That's it. No adjectives, no conclusions.

Keep it somewhere your spouse cannot reach. A new email account with a password you've never used, accessed from a device they don't touch. Not the family computer, not a shared cloud account, not a notes app that syncs to their iPad. I have watched a client's entire private log show up as an exhibit because it backed up to a family Apple ID.

For each piece of evidence, capture the context, not just the content. A screenshot of a message is weak. A screenshot showing the sender, the timestamp, the thread around it, and the device it came from is much stronger. Photograph the screen with a second device if you can, so you have an image with its own metadata. Save originals rather than forwarding, because forwarded material loses the header information that authenticates it.

And write down witnesses. The neighbor who mentioned seeing an unfamiliar car. The friend who was told something. You are not going to call all of these people to testify, but a name you wrote down in March is retrievable, and a memory you didn't write down is not.

The Evidence You Can Legally Gather

The general test, and this is a simplification, is whether you already have lawful access to the thing.

You can generally use:

Joint bank, credit card, and brokerage statements
Phone bills on an account in your name or a joint account, which show numbers and call durations even when they don't show content
Anything visible in a shared space in your own home
Messages your spouse leaves open on a shared device you both use without restriction
Public social media, including the other person's public posts
Photographs you take in public places, or on your own property
Your own recollection, written down contemporaneously
Receipts, hotel confirmations, and reservation emails that arrive in a shared inbox or on paper in your house

Louisiana is a one-party consent state under La. R.S. 15:1303, so you may record a conversation you're actually part of. Twelve or so states require every participant to consent, and if you're calling someone in one of those states the stricter rule can apply to you. Check before you hit record.

The Evidence That Will Ruin You

This is the part I wish more people read before rather than after.

Installing spyware or a keylogger on your spouse's phone or laptop can violate the federal Wiretap Act, the Stored Communications Act, and the Computer Fraud and Abuse Act all at once. These carry criminal penalties and a civil damages action your spouse can bring against you. The fact that you're married doesn't help, and the fact that you pay the phone bill doesn't either.

Logging into their email, their iCloud, or their social media with a password you guessed or found on a sticky note is unauthorized access, even if you've known that password for nine years.

Putting a GPS tracker on their car is a crime in Louisiana under La. R.S. 14:323, which prohibits using a tracking device to determine another person's location without consent. Co-ownership of the vehicle does not exempt you, because the statute protects the person, not the car. Many states have a version of this, and some fold it into their stalking statutes.

Recording a conversation you're not a party to is illegal essentially everywhere.

Beyond the legal exposure, there's a practical problem that I think people underestimate. Evidence obtained this way usually can't be used. Your own attorney may have ethical constraints on even touching it. And it converts your case from one about your spouse's conduct into one about yours. I've sat in hearings where an affair became a footnote because the judge spent forty minutes on how the phone got cloned. Don't hand them that.

If you're not sure whether something crosses the line, the question to ask is simple: did I need to defeat a security measure, or deceive someone, to get this? If yes, stop and call a lawyer first.

Follow the Money, Not the Romance

Here is the thing that surprises clients most. In the cases where infidelity genuinely changes the financial outcome, it usually changes it through the spending, not the sex.

Affairs cost money. Hotels, flights, restaurants, jewelry, a second phone line, sometimes rent on an apartment or a car payment for someone else. In a community property state like Louisiana, that money was half yours. Spouses who spend community funds in bad faith can be held accountable in the partition, and the partition of community property in Louisiana is a separate proceeding from the divorce itself. Equitable distribution states have their own version of this, usually called dissipation or waste.

So while you're being careful about phones, be thorough about paper. Pull and copy the last three years of joint tax returns with all schedules, all bank and credit card statements, retirement and brokerage account statements, mortgage documents, vehicle titles, and any business records. Get your own credit report. Do this now, while you have ordinary access, because once a case is filed this becomes formal discovery that takes months and costs real money.

Look for patterns rather than single charges. Cash withdrawals that started eighteen months ago and run about the same amount every other week. A credit card you don't recognize. Venmo activity. A drop in a bonus that used to come every March. Those are the things a forensic accountant can build on.

Should You Hire a Private Investigator?

Sometimes, and less often than television suggests.

A licensed investigator is worth the money when you need proof of a specific fact that you cannot obtain lawfully yourself, and where that fact will actually move something in your case. In Louisiana, that usually means proving adultery for the fault ground or the support bar. Surveillance producing dated photographs of your spouse entering a residence at night and leaving in the morning is the classic example, and it works because it's lawful observation from a public place.

It's not worth the money if what you want is confirmation. You can spend four thousand dollars learning something you already know, and it will not make you feel better.

Use someone licensed in your state, hire them through your attorney where possible so the work is covered by privilege, and ask up front what they will and won't do. An investigator who offers to get into a phone is offering to destroy your case.

What Adultery Actually Does to Your Divorce

Most of the country has moved fully to no-fault divorce, and in most states proving an affair changes remarkably little. Louisiana is one of the exceptions, and because I practice here, let me use it to show the shape of the thing.

Under Civil Code Article 103(2), adultery is a fault ground, and it gets you an immediate divorce with no separation period. Compare that to Article 103.1, which requires 180 days of living separate and apart with no minor children and 365 days with them. That's a real difference, sometimes close to a year.

Under Article 112, a spouse who was at fault before the petition was filed can be denied final periodic support. This is the provision with actual dollars attached, and it's why adultery gets litigated here when it would be irrelevant two states over. Note that this concerns final support. Interim spousal support, which covers the period while the case is pending, is analyzed differently and fault is not the same bar.

Two traps worth knowing. First, proof is harder than people think. Louisiana courts accept circumstantial evidence, but it must be strong enough to exclude any other reasonable explanation, and a spouse's own testimony needs corroboration. A confession by text helps. Suspicion does not. Second, Article 104 provides that reconciliation extinguishes the cause of action. If you try again for three months and it fails, the adultery ground may be gone. I have had clients lose it that way, and none of them saw it coming.

On custody, be realistic. Courts assess the best interest of the child, and an affair is relevant only where it touched the children: the new partner around the kids in ways that weren't safe, money diverted from their needs, a parent who was absent because of it. A judge who is not asked to referee your marriage will be grateful, and you will look better for it.

Protect Yourself Before You Protect Your Case

Some of this has nothing to do with court.

Get tested for STIs. Every doctor I've ever heard address this says the same thing, and clients routinely put it off for months out of a kind of denial. Do it in the first week.

Change the passwords on accounts that are genuinely yours, starting with your primary email, and turn on two-factor authentication with a number your spouse doesn't control. Consider a credit freeze. Open a checking account in your own name at an institution where your spouse doesn't bank, and start having your mail sent somewhere they don't check. None of that is hiding assets. It's the same basic self-protection I recommend to every client, and it's much harder to arrange after the conversation happens.

And get support that isn't your lawyer. I say this with affection for my own profession: we bill by the hour and we are not trained for grief. A therapist or a divorce coach handles the part legal advice can't, and in my experience clients with that support make calmer and considerably cheaper decisions in my office.

The Mistakes I See Most

Sending the long text. It feels necessary at 1 a.m. It will be Exhibit 3.

Telling the children. They will find out something eventually, but they should not learn it from an angry parent, and a child who's told their father is a cheater is being handed a weight they can't put down.

Posting about it. Even a vague post. Even a private account. Screenshots travel.

Moving out on impulse. It doesn't forfeit your ownership interest, but it can set a temporary custody arrangement, and temporary arrangements have a way of hardening into the status quo a court won't disturb.

Deleting your own material. Your texts, your photos, your emails, even the ones that embarrass you. Destroying potential evidence once a dispute is foreseeable is spoliation, and getting caught at it is worse than whatever you deleted.

Confronting the other person. It accomplishes nothing legally, it can generate a harassment claim against you, and it changes who looks like the reasonable adult.

This article is for general informational purposes only, it is not legal advice, and reading it does not create an attorney-client relationship. Divorce grounds, spousal support standards, property rules, and surveillance statutes vary substantially by state. Louisiana provisions are cited as examples of how these systems work. Consult an attorney licensed in your state before acting on anything here. If you are in an abusive relationship, contact the National Domestic Violence Hotline at 1-800-799-7233.

Frequently Asked Questions

What should I do first if I catch my spouse cheating? Don't confront them yet, and start gathering documents. Copy tax returns, bank and credit card statements, and retirement account records while you still have ordinary access, and begin a dated factual log stored somewhere your spouse cannot reach. Then get one consultation with a family law attorney in your state. Confrontation triggers deletion, password changes, and account closures, so it should come after you've secured what you can, not before.

Can I go through my spouse's phone to get proof of an affair? Not if you have to defeat a password, install software, or access an account you weren't authorized to use. Doing so can violate the federal Wiretap Act, the Stored Communications Act, and the Computer Fraud and Abuse Act, and it exposes you to criminal charges and a civil suit from your own spouse. Material obtained that way is usually unusable in court and shifts the judge's attention from their conduct to yours.

Is it legal to put a GPS tracker on my spouse's car? In Louisiana, no. La. R.S. 14:323 prohibits using a tracking device to determine another person's location or movement without their consent, and co-owning the vehicle does not create an exception, because the statute protects the person rather than the car. Many other states prohibit it as well, sometimes through their stalking statutes. Ask a lawyer in your state before you buy one.

Can I record my spouse's phone calls? You can record a conversation you are actually participating in if you're in a one-party consent state, which includes Louisiana under La. R.S. 15:1303. You cannot record a conversation you're not part of, anywhere. And if the other person is in an all-party consent state, the stricter rule can apply to your call.

Does adultery affect who gets custody? Usually not by itself. Courts decide custody on the best interest of the child, and an affair matters only where it affected the children directly, such as an unsafe person around them, money diverted from their needs, or a parent who became unavailable. Parents who try to make a custody hearing about infidelity generally hurt their own credibility.

Does cheating affect alimony? It depends heavily on the state. In Louisiana, yes: under Civil Code Article 112, a spouse at fault before the divorce petition was filed can be barred from receiving final periodic support, which makes adultery worth proving when support is contested. In most no-fault states, infidelity has little or no effect on a support award unless marital money was spent on the affair.

Can I get money back that my spouse spent on their affair? Often, at least in part. Money spent on hotels, gifts, travel, or a second household came out of marital or community assets, and courts can account for it when dividing property. In Louisiana, the partition of community property is a separate proceeding from the divorce, and bad-faith spending of community funds is addressed there. Bank and card statements matter more here than photographs.

Should I hire a private investigator? Only if you need to prove a specific fact you can't lawfully establish yourself, and that fact will change something in your case. In a fault state, that's usually proof of adultery for the divorce ground or the support bar. If what you want is confirmation of something you already believe, the money is better spent on a therapist. Hire someone licensed in your state, ideally through your attorney.

How long do I have to act after discovering an affair? Sooner than you'd like in fault states. In Louisiana, Civil Code Article 104 provides that reconciliation extinguishes the cause of action for divorce, so attempting to work things out can eliminate the adultery ground entirely. That doesn't mean you shouldn't try to reconcile if you want to. It means you should know the consequence before you decide.
