This popular family law casebook engages students by presenting core family law doctrine while exploring significant transformations in American families and cutting-edge policy debates. It highlights the important role of constitutional law—and other areas of state and federal law—in shaping family law. The book invites students to consider questions of family definition and governmental regulation of families in light of family law's purposes. It charts family law's evolving approach to adult-adult and parent-child (and other caretaker-dependent) relationships, emphasizing that contemporary families take a variety of forms. The Sixth Edition updates all chapters to reflect the latest family law developments, such as the legal treatment of nonmarital families (including plural relationships) and nonbiological parenting as well as recent Supreme Court decisions. It integrates material previously covered in separate chapters on ethical issues in family law practice and jurisdiction into the contexts in which they arise, such as divorce, child custody, and division of marital property. The Sixth Edition has new material highlighting the intersection of family law with race, gender, class, immigration, sexual orientation, and gender identity. As with previous editions, the casebook contains ample problems for students to apply doctrine to realistic factual contexts and highlights practical dynamics of family law practice. The 6th edition: Thoroughly examines the impact of recent Supreme Court cases on family law, including Dobbs v. Jackson Women's Health Organization (and provides teachers with shorter and longer versions of that case), and Golan v.
