Condonation is someone's approval of another's activities. For example, a wife who does not object to her husband's adultery may be said to condone it. If the wife sues her husband for divorce, claiming he has committed adultery, the husband may argue as a defense that she condoned his behavior. Connivance is the setting up of a situation so that the other person commits a wrongdoing. For example, a wife who invites her husband's lover to the house and then leaves for the weekend may be said to have connived his adultery.
Provocation is the inciting of another to do a certain act.
If a spouse suing for divorce claims that the other spouse abandoned her, her spouse might defend the suit on the ground that she provoked the abandonment. But think twice before you raise a defense to a fault divorce. First, proving a defense may require witnesses and involve a lot of time and expense. Second, your efforts will likely come to nothing. Chances are good that a court will eventually grant the divorce, because there is a strong public policy against forcing people to stay married when they don't wish to be.
