Connivance

The secret or indirect consent or permission of one person to the commission of an unlawful or criminal act by another. Literally, a winking at; intentional forbearance to see a fault or other act; generally implying consent to it.

Webster.

Connivance is the corrupt consent of one party to the commission of the acts of the other, constituting the cause of divorce.

Civil Code Cal. § 112.

Connivance differs from condonation, though the same legal consequences may attend it. Connivance necessarily involves criminality on the part of the individual who connives; condonation may take place without imputing the slightest blame to the party who forgives the injury. Connivance must be the act of the mind before the offense has been committed; condonation is the result of a determination to forgive an injury which was not known until after it was inflicted.
