What is the equitable sharing of the financial consequences of a breakdown in a long term relationship?

Moge v. Moge, 1992 CanLII 25 (SCC), [1992] 3 S.C.R. 813, discusses the equitable sharing of the financial consequences of relationship breakdown, particularly in long term relationships. The economic consequences of a breakdown in a relationship should not be borne by one party alone or disproportionately. The obligation to assist a spouse with the economic consequences of a breakdown in a relationship should be borne by the other spouse and not the state. The court stated the following, at page 870, concerning long term relationships: As marriage should be regarded as a joint endeavour, the longer the relationship endures, the closer the economic union, the greater will be the presumptive claim to equal standards of living upon its dissolution.
