Is it illegal to tell others that your wife is cheating?

Legal analysis: in the legal sense, it is not illegal, but you can't make things up and add events at will. So as not to bring unnecessary trouble.

Legal basis: Article 1079 of the Civil Code of People's Republic of China (PRC), if one of the spouses requests a divorce, the relevant organization can mediate or directly file a divorce lawsuit with the people's court. When trying divorce cases, the people's court shall conduct mediation; If the relationship has indeed broken down and mediation is ineffective, divorce should be granted. In any of the following circumstances, if mediation fails, divorce shall be granted:

(a) bigamy or cohabitation with others;

(2) committing domestic violence or abusing or abandoning family members;

(three) gambling, drug abuse and other bad habits;

(four) separated for two years due to emotional discord;

(5) Other circumstances that lead to the breakdown of the marriage relationship.

If one party is declared missing and the other party files a divorce lawsuit, the divorce shall be granted. After the people's court ruled that divorce is not allowed, if the two parties have separated for one year and one party files a divorce lawsuit again, divorce shall be granted.
