Disaggregating property rights into abstract bundles of rights over the use, control, and alienation of property facilitates the systematic comparison of property regimes across time and space. However, because these analytic distinctions ignore the criteria by which individuals choose among competing claims of ownership, they cannot capture the moral reasoning that ultimately institutionalizes a property regime. Using focus group debates over competing claims of ownership to newly privatized urban real estate, this essay identifies four grounded logics of entitlement by which Shanghai residents determine just claims in one post-socialist property regime: a logic of family justice, a logic of state regulation, a logic of the market, and a logic of the family estate. Of note is that the primary criteria by which individuals decided among different logics of entitlement were the rules of the property regime at the time the dwelling first became the family home rather than differences attributable to societal inequalities tied to distinctions of gender, generation or occupation.
