Can You Sue Your Spouse’s Lover? Understanding Alienation of Affection Laws
Explore when you can sue a spouse’s lover, how alienation of affection works, and which states still allow these highly controversial lawsuits.
Discovering that a spouse has been unfaithful often produces anger, grief, and a strong desire for accountability. One of the first questions many people ask is: “Can I sue the person my spouse cheated with?” In a few states, the answer is yes — under legal theories known as alienation of affection and criminal conversation.
This guide explains how these lawsuits work, which states still allow them, what you would need to prove, and what practical considerations to weigh before going down this path.
1. Marital Torts: Suing a Third Party Over an Affair
Claims against a spouse’s lover fall under a group of civil wrongs sometimes called “marital torts.” They do not send anyone to jail; instead, they seek money damages for harm done to the marital relationship.
The two main types are:
- Alienation of affection – a claim that a third party wrongfully destroyed the love and affection in a marriage.
- Criminal conversation – a claim based on proof that a third party had sexual relations with a married person without the consent of the other spouse.
Despite the term “criminal,” criminal conversation is a civil claim, not a criminal charge.
2. Where Can You Sue a Spouse’s Lover?
Most states have abolished these claims as outdated or inconsistent with modern views of marriage and personal autonomy. However, a small number still recognize them, usually under state case law or specific statutes.
| Type of Claim | General Description | Typical Availability |
|---|---|---|
| Alienation of affection | Third party intentionally causes loss of love and affection in a marriage. | Recognized in only a few states (often by statute or case law). |
| Criminal conversation | Third party has sexual intercourse with a married person without the other spouse’s consent. | Recognized in even fewer states than alienation of affection. |

Because the list of states that permit these suits can change through legislation or court decisions, and because requirements vary significantly, it is critical to:
- Review your current state law, and
- Speak with a local family law or civil litigation attorney before assuming you can file a claim.
3. Understanding Alienation of Affection
Alienation of affection is a tort that allows a spouse (or former spouse) to sue a third party for wrongfully interfering with the marriage and causing the loss of love, affection, comfort, or consortium.
In plain terms, the injured spouse claims:
- “We had a meaningful marital relationship,” and
- “This person’s actions intentionally pulled my spouse away and destroyed our marriage.”
3.1 Core Elements You Typically Must Prove
While each state’s rules differ, courts that recognize alienation of affection generally require several key elements.
- Existing marital relationship with genuine affection
You must show the marriage had real love, affection, or companionship, even if it was imperfect. Evidence could include shared activities, communication, plans for the future, or testimony from friends and relatives about the relationship. - Significant loss of affection
You must show that the marital love or companionship was substantially reduced or destroyed. Courts often look for a “significant” decline, not just routine arguments or temporary conflict. - Wrongful and intentional interference by the defendant
The third party must have engaged in conduct that was malicious or intentional in disrupting the marriage – for example, encouraging the affair, promoting secrecy, or undermining the spouse’s commitment. - Causation
You must connect the dots: show that the defendant’s conduct was a substantial factor in the breakdown of marital affection, even if there were other problems as well. - Damages
Many jurisdictions require proof of actual harm – such as emotional distress, loss of financial support, or other measurable consequences of the marriage’s breakdown.
3.2 Who Can Be Sued?
Although these suits most often target a lover or romantic partner, some states allow claims against non-romantic third parties who intentionally interfere in a marriage. Those might include:
- Family members encouraging separation or divorce
- Close friends urging a spouse to leave
- Employers or colleagues whose conduct is aimed at destroying the marital relationship
The key issue is intentional, wrongful interference with marital affection, not just disagreement or casual advice.
4. Understanding Criminal Conversation
Criminal conversation is narrower and, in some ways, easier to understand. It focuses on one fact: proof that the defendant had sexual intercourse with your spouse during the marriage.
4.1 Typical Requirements
In jurisdictions that still recognize criminal conversation, the injured spouse generally must show:
- A valid, existing marriage at the time of the alleged sexual relationship.
- Sexual intercourse between the defendant and the married spouse.
Unlike alienation of affection, you do not usually have to prove:
- Loss of affection
- Malicious intent
- Causation between the sexual act and the breakdown of the marriage
However, evidence in these cases can be extremely personal and intrusive. Courts allow circumstantial proof (such as hotel receipts, text messages, or eyewitness accounts) because direct evidence of sexual activity is rarely available.
5. Evidence Commonly Used in These Cases
Because alienation of affection and criminal conversation claims ask a court or jury to examine the inner workings of a relationship, the evidentiary burden can be high and emotionally taxing.
Common forms of evidence include:
- Digital communications
Text messages, emails, messaging app logs, and social media posts can be used to show the nature of the relationship and efforts to conceal it. - Photos and videos
Images showing affection, intimacy, or travel together may support claims of a romantic or sexual relationship. - Financial records
Bank and credit card statements might show gifts, trips, or joint expenses that support the existence and impact of the affair. - Witness testimony
Friends, family, co-workers, or neighbors may testify about what they observed — both about the marriage before the affair and the conduct of the alleged lover. - Spousal testimony
The unfaithful spouse often becomes a key witness about the state of the marriage and the extent of the third party’s involvement.
Because privacy concerns are significant, courts may issue protective orders or confidentiality measures, but much of the evidence still becomes part of the public record.
6. Limitations, Defenses, and Time Deadlines
Even in states that recognize these torts, there are important limits and defenses that can defeat or reduce a claim.
6.1 Common Defenses
- No genuine affection existed
The defendant may argue the marriage was already effectively over — for example, that the couple was separated or in serious, longstanding conflict before the affair. - Defendant did not cause the breakdown
The defense may present evidence that other factors (such as financial problems, addiction, or incompatibility) were the primary cause of the marital breakdown, not the defendant’s actions. - Lack of intent or knowledge
A third party might argue they did not know the person was married or had no intent to disrupt the marriage. - Consent or condonation
In some contexts, prior agreement to open relationships or subsequent forgiveness may complicate or weaken a claim.
6.2 Statutes of Limitation (Filing Deadlines)
Like most civil cases, alienation of affection and criminal conversation suits must be brought within a specific statute of limitations. If you wait too long, your claim may be barred permanently, even if your evidence is strong.
The exact deadline and how it is calculated (for example, from the date of the last wrongful act or from discovery of the affair) depends on your state’s law. Consulting a lawyer promptly is essential to avoid missing these deadlines.
7. What Damages Can You Seek?
Successful plaintiffs may be awarded several types of damages, depending on state law and the facts of the case.
- Compensatory damages
These aim to compensate for measurable harm, such as:- Loss of financial support or benefits from the spouse
- Therapy or counseling expenses
- Loss of household services
- Non-economic damages
These address intangible injuries like emotional pain, humiliation, and loss of companionship. - Punitive damages
In some cases, courts may award additional sums to punish especially egregious or malicious conduct and to deter similar behavior.
Large verdicts in a few highly publicized cases have drawn attention to these lawsuits, but outcomes vary widely and depend heavily on the specific evidence presented.
8. Why Many States Abolished These Claims
The majority of U.S. states have chosen to abolish alienation of affection and criminal conversation for several reasons:
- Concern that these suits treat spouses as property rather than autonomous partners
- Belief that they encourage vindictive litigation rather than healing
- Recognition that multiple factors, not just one person, typically contribute to marital breakdown
- Fear of blackmail or abusive use of the claims for leverage in divorce negotiations
Despite this trend, some states have kept the claims, reasoning that they provide a civil remedy for seriously injured spouses and may deter people from interfering in marriages.
9. Practical Considerations Before Filing
Even if your state permits suits against a spouse’s lover, filing one is a major decision. Factors to weigh include:
- Emotional impact
Litigation requires revisiting painful events in detail and can prolong conflict and distress. - Costs and time
Lawsuits can be expensive and may take months or years to resolve. There is no guarantee of success or of collecting any judgment awarded. - Public exposure
Much of the evidence and testimony becomes part of the public record, which can affect careers, children, and extended families. - Effect on divorce proceedings
In some states, the possibility of a lawsuit against a lover may influence settlement negotiations in the underlying divorce case, for better or worse. - Alternative remedies
Many spouses instead focus on divorce, property division, and spousal support claims, which may address financial and practical needs more directly.
Because circumstances differ widely, tailored legal advice is crucial. Professional counseling or therapy may also be an important part of navigating the emotional fallout of infidelity.
10. Frequently Asked Questions
Q1: Can I sue my spouse and their lover at the same time?
In most systems that allow alienation of affection or criminal conversation, the claim is against the third party, not the unfaithful spouse. Your spouse’s conduct is typically addressed through divorce, separation, or other family law proceedings, while the tort action targets the alleged lover.
Q2: Do we have to be divorced before I can file?
Not necessarily. In many jurisdictions that permit alienation of affection, the couple does not need to be divorced for the claim to proceed. The central question is whether the defendant’s conduct caused a loss of marital affection, regardless of marital status at the time of filing.
Q3: What if my spouse says the marriage was already over?
Defendants often argue that the marriage was failing before they entered the picture. Courts then examine evidence of the state of the relationship before the affair — including communications, witness testimony, and the couple’s conduct — to determine whether genuine affection still existed and whether the defendant materially contributed to its destruction.
Q4: Can same-sex spouses bring these claims?
Where same-sex marriage is fully recognized, courts generally apply marital tort principles without regard to the spouses’ genders. However, whether alienation of affection or criminal conversation is available at all still depends entirely on each state’s substantive law and judicial decisions.
Q5: Is talking to a lawyer confidential if I am not sure I want to sue?
Yes. Communications with a licensed attorney for the purpose of seeking legal advice are typically protected by attorney–client privilege, meaning they are confidential and cannot be disclosed without your consent, subject to limited exceptions recognized in evidence rules and professional conduct codes.
