AbstractThis article illuminates the legal regulation of the economic rights of non‐marital partners at separation or death. Current approaches have typically fallen into two categories: one advocating for the separation of legal regimes based on formal status, treating cohabitant partners as strangers, and the other taking a functional approach, treating cohabitation and marriage as substantively identical. However, both approaches fail to offer a coherent alternative for regulating cohabitation. This article proposes a novel third option – the institutional, autonomy‐based, pluralist model. The pluralist model acknowledges the legal commitment between cohabitants while carefully distinguishing the legal regulation of cohabitation from that of marriage. Unlike prevailing models that offer a “package deal,” the pluralist model selectively applies only suitable components of marriage law to non‐marital relationships, considering thoughtful criteria for their applicability and ensuring a nuanced approach. The pluralist model offers a middle ground between treating cohabitants as strangers and treating them as married for purposes of regulating marital property, spousal support, and inheritance. Ultimately, it provides a framework that considers the complexities of non‐married relationships while maintaining a desirable level of legal clarity.
