Collusion has often been used in Divorce proceedings. In the past some jurisdictions made it extremely difficult for a couple to obtain a divorce. Often a "sweetheart" agreement would take place, whereby a husband or wife would commit, or appear to commit, Adultery or other acts that would justify a divorce. The public policy against collusive divorces is based on the idea that such actions would conflict with the effective administration by society of laws on marriage and divorce and would undermine marriage as a stabilizing force in society.

Virtually all jurisdictions have adopted no-fault divorce statutes or laws that allow a couple to obtain a divorce without traditional fault grounds, such as adultery or cruel and inhuman treatment. Because of this development, collusive divorces should diminish in number, since it will no longer be necessary for persons seeking a divorce to resort to such measures.

The fundamental societal objection to collusion is that it promotes dishonesty and fraud, which, in turn, undermines the integrity of the entire judicial system.


n. where two persons (or business entities through their officers or other employees) enter into a deceitful agreement, usually secret, to defraud and/or gain an unfair advantage over a third party, competitors, consumers or those with whom they are negotiating. Collusion can include secret price or wage fixing, secret rebates, or pretending to be independent of each other when actually conspiring together for their joint ends. It can range from small-town shopkeepers or heirs to a grandma's estate, to gigantic electronics companies or big league baseball team owners. (See: fraud)
