In some states and provinces adultery is considered grounds for divorce.
Courts once used adultery to punish the guilty because it was the sole ground for divorce in some jurisdictions.
Today courts focus more on the economic impact of adultery. In most states, marital misconduct or fault, such as adultery, is not considered, however. For example, committing adultery typically will not have a bearing on whether a parent can get custody of his or her child because it takes two people to do it. No one ever committed adultery alone. The logic of two-to- tango removes factors in making the best decision.
Judges now pay more attention to the economic impact of marital misconduct, such as the assets.
