[Reasons for Recognition] Facts that there is no dispute between the parties, Gap evidence Nos. 1, 2, 7 through 10 (including paper numbers), witness F's testimony, the purport of the whole pleadings

2. Determination:

(a) Husband and wife shall live together, and have the obligation to support and cooperate with each other;

(Article 826 of the Civil Act). Husband and wife, as a community in which mental, physical, or economic combination is achieved, shall have the duty to cooperate and protect each other in a comprehensive manner so that marriage as a marital community is maintained, and shall have the right to such a duty.

As such, as the content of the marital or marital life maintenance obligation, the married couple bears the sexual duty that should not commit any unlawful act.

The "Cheating" here is a broad concept, including the adultery, which does not reach the gap, but includes all unlawful acts that do not fulfill the duty of mutual assistance of the couple. If one of the married couple commits an unlawful act, the other spouse is liable to compensate for the mental suffering suffered by the spouse.

On the other hand, a third party shall not interfere with a married couple’s community life, which is the essence of the marriage, such as interfering with a couple’s community life by interfering with another person’s community life.

A third party has committed a fraudulent act with either side of the married couple.
