The merits and means of accommodating non-binary populations into UK law is becoming an increasingly important issue for policymakers, judges, scholars and legal professionals. Following Elan-Cane's Supreme Court challenge to binary passport sex markers in 2021, the UK Government face another challenge this year concerning non-binary recognition on birth certificates. While an additional third sex option is perhaps the most well-known reform option for the current binary system, other options have been suggested, including additional multiple sex options and/or removing sex from the birth certificate. While scholars and policymakers debate the merits of these, little is known about non-binary people's own preferences towards these options. This paper therefore presents original empirical data on non-binary attitudes towards these options, demonstrating the various perceived opportunities and drawbacks of each, and reflecting on the possible consequences of reform.
