Despite a rich literature in law and society embracing contracts as exchange relations, empirical work has yet to consider their emotional dimensions. I explore the previously unmapped case of surrogacy to address the interface of law and emotions in contracting. Using 115 semistructured interviews and content analyses of 30 surrogacy contracts, I explain why and how lawyers, with the help of matching agencies and counselors, tactically manage a variety of emotions in surrogates and intended parents before, during, and after the baby is born. I establish that a web of “feeling rules” concerning lifestyle, intimate contact, and future relationships are formalized in the contract, coupled with informal strategies like “triage,” to minimize attachment, conflicts, and risk amidst a highly unsettled and contested legal terrain. Feeling rules are shared and embraced by practitioners in an increasingly multijurisdictional field, thereby forging and legitimating new emotion cultures. Surrogacy offers a strategic site in which to investigate the legalization of emotion—a process that may be occurring throughout contemporary society in a variety of exchange relations.
