1. Lawsuit Against the Adulterous Partner (Female) | Requirements for Filing

A lawsuit against the adulterous partner (female) is a civil action in which, when a spouse engages in an act of infidelity with a third party during marriage, consolation money for emotional harm is claimed against that third party, the adulterous partner.
This is not merely an emotional response to an affair, but a type of claim for damages arising from a tort, holding the third party who destroyed the family legally responsible (Article 750 of the Civil Act).
To file a lawsuit against the adulterous partner, the following requirements must be met.
② The marital relationship was effectively broken down by the act of infidelity
③ Emotional suffering resulted from it
Existence of an Act of Infidelity
The most important requirement in a lawsuit against the adulterous partner is the existence of an act of infidelity.
An act of infidelity is not mere fondness or social interaction, but, from the perspective of an ordinary person, requires sexual contact or an intimate relationship to a degree that can be regarded as a violation of the spousal duty of fidelity (Article 826 of the Civil Act).
What is the duty of fidelity?
Example circumstances
▷ Traveling alone together for an extended period
▷ Overt displays of affection
A mere exchange of text messages or meetings at the level of friendship, however, are difficult to recognize as an act of infidelity.
In addition, it is not necessary to prove that sexual relations actually occurred; an act may be recognized based solely on circumstances amounting to infidelity.
Breakdown of the Marital Relationship
One of the important issues in a lawsuit against the adulterous partner is whether the act of infidelity actually harmed the couple's marital relationship.
In other words, consolation money liability is recognized only where the adulterous partner's conduct substantially broke down the marital relationship, or at least where there are circumstances showing that it affected the breakdown of the marriage.
If the marital relationship had already broken down, however, it is difficult to hold the adulterous partner responsible.
For example, if the couple has continued to live separately and the marriage has in effect ended, the adulterous partner's act of infidelity cannot be regarded as the cause of the breakdown of the marriage.
This point has also been stated in Supreme Court precedent.
Supreme Court, Decision of November 20, 2014, 2011Meu2997
If the marital communal life has substantially broken down to a state that cannot be restored, then even if a third party engages in a sexual act with one of the spouses, this cannot be regarded as an act that infringes upon the marital communal life or interferes with its maintenance, and it also cannot be said that harm arises infringing upon the spouse's rights concerning the marital communal life, so it is difficult to find that a tort has been committed.
Ultimately, whether the marital relationship was substantially maintained at the time of the act of infidelity becomes the key criterion for recognizing consolation money through a lawsuit against the adulterous partner.
Causing Emotional Suffering
To claim consolation money against the adulterous partner, the injured spouse must prove that they suffered emotional distress as a result of the act of infidelity.
Because emotional suffering is difficult to prove directly, it is generally assessed by comprehensively considering the duration of the act of infidelity, its repetition, its content, and the victim's reactions.
Filing Period and Whether to Divorce
Under Article 766 of the Civil Act, a lawsuit against the adulterous partner may be filed within the following periods.
Criterion | Period |
Date of becoming aware of the damage and the perpetrator caused by the tort | Within 3 years |
Date on which the tort occurred | Within 10 years |
In addition, a claim for consolation money through a lawsuit against the adulterous partner is a right separate from divorce.
In other words, even if the parties have not divorced, a claim for consolation money for the emotional harm resulting from the act of infidelity may be exercised independently.
2. Lawsuit Against the Adulterous Partner (Female) | Claim for Consolation Money

The consolation money that may be claimed in a lawsuit against the adulterous partner varies depending on the gravity of the case and the circumstances of the act of infidelity.
Average Amount
It is often recognized in the range between 5 million won and 30 million won.
However, consolation money is not a fixed amount; the court determines it individually by comprehensively considering the form and result of the act of infidelity, the degree of the adulterous partner's involvement, and the victim's suffering.
Factors in Determining Consolation Money
The court generally determines the amount of consolation money by comprehensively considering the following factors.
② The length of the marriage between the plaintiff and the spouse
③ The period over which the act of infidelity continued and its specific degree
④ How seriously the marital relationship broke down as a result of the act of infidelity
⑤ The couple's financial situation and standard of living
⑥ Whether there are children and whether the children are being raised
⑦ The degree of emotional suffering sustained by the plaintiff
3. Lawsuit Against the Adulterous Partner (Female) | Evidence for Proof

In a lawsuit against the adulterous partner, three key facts must largely be proven.
▷ That emotional suffering resulted from that act of infidelity
▷ That the adulterous partner was aware that the husband was married
The materials and methods for proving these three points will be examined separately as follows.
Materials for Proving an Act of Infidelity
To prove the existence of an act of infidelity, objective circumstances sufficient to recognize a 'violation of the duty of fidelity' from the perspective of an ordinary person are needed.
Key evidence | Details |
Text messages, SNS conversations | Content containing arrangements for secret meetings, expressions of affection, and the like |
Photographs and videos | Footage from which an act of infidelity may be inferred, such as scenes of entering a motel or affectionate moments during travel |
Call records and location records | Frequent late-night calls and records of simultaneous presence at a particular location |
Eyewitness statements by third parties | Evidence of acquaintances of the adulterous partner or the spouse testifying in court |
Materials for Proving Emotional Suffering
Emotional suffering is difficult to prove directly, but it may be recognized through circumstances such as the following.
: Whether the adulterous conduct was a one-time occurrence or was continuous and repeated
▷ The victim's psychological state and reactions
: Depression, stress, counseling records, and statements of family and friends
▷ The degree of breakdown of the marital relationship
: Separation, whether divorce proceedings are underway, the severity of family discord, and the like
▷ Whether a certified content-confirmed letter was sent before claiming consolation money
: The fact of having notified the other party of the emotional suffering
Materials for Proving the Other Party's Awareness and Acknowledgment of Responsibility
Proving that the adulterous partner knew, or could have known, that the other spouse was a married person is very important for establishing the adulterous partner's tort liability.
This is because if the adulterous partner did not know that the husband was married, a tort may not be constituted.
The Supreme Court has also stated this point as follows.
Supreme Court, Judgment of August 18, 1987, 87Meu19
Accordingly, if it cannot be proven that the adulterous partner was aware or could have been aware that the partner was married, there is a strong likelihood that the court will deny liability, so securing evidence on this point is critical to the claim.
Key supporting materials
(proving that the adulterous partner was aware of the marriage)
∙ Written statements or testimony of people in the vicinity
(proving that the adulterous partner was aware of the marriage)
∙ Audio or video material in which the other party mentioned the existence of a spouse
∙ Publicly disclosed materials concerning the marriage
(a family photograph inside a vehicle, a family relationship certificate, a divorce petition, and the like)
∙ Other circumstantial evidence from which the marriage could be known
(e.g. : confirmation of a shared residence, the adulterous partner's statements indicating awareness, and the like)

4. Lawsuit Against the Adulterous Partner (Female) | How the Injured Spouse Responds

An injured spouse (the plaintiff) who needs to file a lawsuit against the adulterous partner should prepare thoroughly at each stage and claim consolation money.
Drafting the Complaint and Filing It With the Court
A lawsuit against the adulterous partner is a civil action and a claim for damages.
To file the lawsuit, a complaint claiming damages must first be drafted.
The following content should be included.
∙ Content that can prove the marriage is still subsisting
∙ Specific facts that the defendant committed an act of infidelity with the plaintiff's spouse
∙ The causal relationship between the breakdown of the marriage and the act of infidelity
∙ The content of the emotional harm and the basis for calculating the consolation money amount
The drafted complaint may be filed with the family court if it is premised on divorce, and with an ordinary civil court otherwise.
Filing of the Other Party's Answer and Examination of Evidence
Once the complaint is received, the defendant must file an answer within 30 days from the date the complaint is served.
Based on this, the answer filed by the opposing adulterous partner is reviewed to identify the rebuttal arguments and evidence.
Pleading Date
At the pleading date, the arguments of both sides are exchanged, and witness examination, examination of evidence, and the like may take place, so it is necessary to organize the content of the statements and prepare witnesses in advance.
At this point, the plaintiff who filed the lawsuit against the adulterous partner must specifically prove the following matters.
∙ That the adulterous partner who engaged in the affair was aware that the husband was married
∙ That the affair conduct effectively broke down the marital relationship of the plaintiff's marriage
∙ That the plaintiff is experiencing emotional suffering as a result of the affair conduct
Rendering of Judgment
Once all proceedings are concluded, the court issues a judgment by comprehensively considering the evidence and arguments.
If a party wishes to contest the court's judgment, they may appeal within 14 days after the judgment is served.
When Consolation Money Is Not Paid
Even though a judgment ordering payment of consolation money has been rendered, if the adulterous partner does not pay the consolation money, an order to comply may be requested from the family court.
An order to comply refers to an order by which the family court, when a person fails to perform a property obligation such as the payment of money under a judgment of the family court without justifiable reason, directs that person to perform the obligation within a certain period (Article 64(1) of the "Family Litigation Act").
If the adulterous partner still does not pay the consolation money after receiving an order to comply, an administrative fine may be imposed and a detention order may be issued against them.
Failure to pay consolation money without justifiable reason | An administrative fine of up to 10 million won |
Failure to pay consolation money for three or more installments without justifiable reason | Detention within a range not exceeding 30 days |
In addition, there is also a method of applying for compulsory execution and receiving the consolation money through an auction disposition.
5. Lawsuit Against the Adulterous Partner (Female) | How the Defendant Can Respond

If you have been named as the defendant in a lawsuit against the adulterous partner (female), you may feel a sense of injustice and confusion.
However, there is ample room to mount a legal defense, and depending on how you respond, your liability for consolation money may be eliminated or reduced.
The following are the main steps a defendant can take.
Initial Response After Service of the Complaint
If you have received a complaint served by the court, the first thing to do is to accurately grasp the relief sought and the underlying facts.
You should review the contents of the complaint carefully and check the following points.
• If there was an act of infidelity, how often and in what manner did the relationship take place?
• Did you know that the plaintiff's husband was married?
• Was the plaintiff couple's marital relationship still intact at that time?
If you did not know that the other party was married, liability may not be recognized.
Therefore, it is advisable to keep circumstantial materials or notes on the situation at the time that can prove you did not know about the marital status.
Filing an Answer and Constructing the Defense Logic
The answer must be filed within 30 days of the date the complaint is served, and it is the document that officially sets out your position.
Depending on the situation, you can build your defense around the following arguments.
▷ The argument that you did not know the other party was married and had no way of knowing
▷ The argument that, before any act of infidelity, the plaintiff couple were already effectively separated or their marriage had broken down
▷ The point that the mental suffering claimed by the plaintiff is exaggerated
It is also advisable to prepare materials that can rebut the plaintiff's claims, such as conversation records, statements from third parties, and materials explaining the circumstances of the relationship.
• Messages and conversation records with the plaintiff's spouse
• Receipts or photographs that can prove the plaintiff's claims differ from the facts
Conciliation Proceedings and Considering a Settlement
Many lawsuits against the adulterous partner (female) are resolved through conciliation proceedings.
Even if an act of infidelity is recognized as fact, you can reduce the burden of litigation by agreeing on the amount of consolation money or the method of payment.
If you want to minimize emotional conflict with the plaintiff and reach a quick resolution, you may also consider acknowledging partial liability while presenting grounds for mitigation to encourage conciliation.
