Adultery is not a ground for divorce in jurisdictions which have adopted a no-fault divorce model.
A distinction should be noted between extramarital sex, which is sex by someone (or with someone) who is already married to another person, versus premarital sex, which is sex between persons who are neither married to each other nor married to any other person.
Historically, many cultures have considered adultery to be a very serious crime, sometimes akin to murder or grand larceny due to the effect of extinguishing the true line of descendants and heirs of a victim husband.
Thus, adultery often incurred severe punishment, usually, and historically, for the married woman committing adultery.
Another tort, alienation of affection, arises when one spouse deserts the other for a third person.
A marriage in which both spouses agree ahead of time to accept sexual relations by either partner with others is sometimes referred to as an open marriage or the swinging lifestyle.
Although the legal definition of adultery differs in nearly every legal system, the common theme is sexual relations outside of marriage, in one form or another.
