Divorce (or the dissolution of marriage) is the final termination of a marital union, canceling the legal duties and responsibilities of marriage and dissolving the bonds of matrimony between the parties.
The Jaffa on Chulak also have a divorce like proceeding called a 'pledge break'. If a dispute cannot be resolved, it is requested by one and granted by the other. If that fails, a weapon is required. (SG1: "Affinity")
