Connivance is a defence where a spouse accused of adultery claims that the other spouse consented.
The availability of no-fault divorce has likely made the connivance defence less prevalent.
Connivance is sometimes used more broadly to describe when a person, in bad faith, ignores another person's wrongful act or implicitly consents to its commission.
The relevance of connivance as a defence may vary depending on the jurisdiction and the availability of no-fault divorce.
While connivance involves consent to a specific act like adultery, collusion involves a mutual agreement to deceive the court for obtaining a divorce.
Although most commonly used in divorce cases, the term can also refer to ignoring another person's wrongful act or implicitly consenting to its commission in other contexts.
