This article raises two core questions. Firstly, in pursuing the aim of “family harmony” at the state level, what should law be trying to influence? The challenge here is to identify a model of the determinants of “family” that is adequate for legal purposes and that illustrates the entry points where law could best be used as an instrument of public policy. Secondly, what strategies and tools can law offer to securing families and exploring sexuality? This project provides a conceptual framework for re-thinking about the role of law in responding to intimacy, especially family and sexuality in Taiwan. I will examine current Taiwanese law and regulations, including civil law, criminal law, administrative law, artificial insemination law, nationality law and regulations, and analyze their inherent sex/gender、race、class nationality bias. The author advocates Taiwanese legal system should look into the social reality in which distinctive forms of intimacy thrive, and recompose a more done-to-earth mechanism to regulate intimate relationships if the justified governmental interest is found.
