Send a message to the client that her husband is having an affair and call the police. Will you be detained?

Basically not, but you will be arrested for bigamy.

Mainly because this kind of cases mainly belong to civil aspects, in our current law, extramarital affairs do not bear criminal responsibility, which belongs to the category of moral adjustment, but it violates the legislative spirit of the Civil Code, that is, it violates the provision in Article 1043 of the Civil Code that husband and wife should be faithful and respect each other. If the husband and wife divorce, the innocent victim can sue the court for divorce and ask the other party for mental compensation.

According to: Article 109 1 of the Civil Law, in case of divorce under any of the following circumstances, the innocent party has the right to claim damages: (2) cohabiting with others. Only when an extramarital man and woman live together in the name of husband and wife can it constitute bigamy. The injured party can bring a lawsuit to the court with relevant evidence, demanding that he be investigated for criminal responsibility.

Extramarital affairs are usually secret, and it is extremely difficult to obtain evidence by mobile phone. On the other hand, if the scale of proof is too large, the court may not adopt it because the way of obtaining evidence is illegal or infringes on the privacy of others. So learn to prove the fact that the other party has an affair perfectly.
