Does the principle of unjust enrichment apply to family law cases?

Although Iacobucci J. was speaking in the commercial context, the principles of unjust enrichment apply equally to family law cases. In this regard, I note that McLachlin J. observed the following at ¶24 of Peter v. Beblow: I doubt the wisdom of dividing unjust enrichment cases into two categories—commercial and family—for the purpose of determining whether a constructive trust lies. A special rule for family cases finds no support in the jurisprudence.
