Biography

Katharine Silbaugh is widely recognized for her pioneering work on gender, family and household labor, and adolescent interaction with the legal system. Her research highlights the economic and social value of work done within households; the complex relationship between families and institutions, such as employers, schools, and commercial entities; and the inadequacy of the legal framework supporting families and protecting youth. Her publications about the relationship between institutions and family address a range of legal systems including family law, employment law, urban planning, education law, election law, first amendment law, technology platforms, and controlled substances. She has intervened in policy matters including marriage equality litigation, anti-bullying law and policy, and tobacco and nicotine regulation.

Professor Silbaugh clerked for Judge Richard Posner of the US Court of Appeals for the Seventh Circuit. She later collaborated with Posner on a survey of sexual regulation, A Guide to America’s Sex Laws, published by the University of Chicago Press. She is co-author of The Essentials of Family Law (2009) with Katharine K. Baker. She also is the author of numerous journal articles and book chapters, including the landmark article “Turning Labor into Love: Housework and the Law” for Northwestern Law Review.  Professor Silbaugh contributed to the plaintiffs’ case in Goodridge v. Department of Public Health, the Massachusetts case that won the nation’s first same-sex marriage right in 2004. She has provided advice on anti-bullying legislation to the Berkman Center for Internet & Society’s Youth Meanness and Cruelty Project and serves on several education-related boards and committees. She served for 15 years as an elected representative in local government.

Professor Silbaugh joined the Boston University faculty in 1993, received tenure and a full professorship in 1998, and was named Law Alumni Scholar in 2007 and The Honorable Frank R. Kenison Distinguished Scholar in Law in 2024. She served as the associate dean for academic affairs from 2004 until 2006. She spent the 2006-2007 academic year and Fall 2009 as a visiting professor at Harvard Law School, and was a visiting Professor of Law at Chuo University in Toyko in the Fall of 2007. She was elected to the American Law Institute in 2017, and named Brookline, Massachusetts’ “Woman of the Year” in 2022. She teaches Family Law; Youth and the Law; Education Law; and Torts. Professor Silbaugh was the recipient in both 2004 and 2021 of the Michael Melton Award for Excellence in Teaching.

LAW JD 811

Family Law

3 credits

This course offers a survey of family law, including case law, statutory law, and the role of constitutional rights in limiting governmental regulation of the family. This course will introduce students to law concerning a basic social institution: the family. Students will gain knowledge about how family law intersects with many other fields of law, such as contracts, constitutional law, criminal law, property, torts, public and social welfare law, as well as how social science informs family law. The course will focus on marriage (including the recognition of same-sex marriage), nonmarital families, divorce, pathways to becoming a parent, and the parent-child relationship. Topics include defining and regulating marriage; formal marriage; common law marriage; nonmarital couples, cohabitation, and alternatives to marriage; common law incidents of marriage and the transformation of the common law; domestic violence; traditional and "no fault" divorce; property division; spousal support; child support; child custody; adoption; and regulating parenthood. There will be a final examination. The teaching method is a combination of lecture and class discussion, along with in-class small group problem-solving exercises. GRADING NOTICE: This class does not offer the CR/NC/H option.

Family Law

4 credits

This course offers a survey of family law, including case law, statutory law, and the constitutional limitations on regulation of the family. The course aims to introduce students to family law as a dynamic field of law concerning a basic social institution: the family. Family law is a foundational course relevant to many areas of law practice. Students will gain knowledge about how family law intersects with fields of law, such as contracts, constitutional law, conflicts of laws, criminal law, property, tax, and trusts and estates, and how family law draws on the social sciences. We will examine the role of family law in contributing to and ameliorating inequalities in society on various bases, including gender, race, class, and sexual orientation. Students will be introduced to the role of negotiation, mediation, and other forms of dispute resolution in family law practice. Topics include defining and regulating family (including marriage and parenthood); formal and informal marriage; cohabitation and alternatives to marriage (such as domestic partnerships); common law incidents of marriage and the transformation of the common law; marital agreements; intimate partner violence; traditional and "no-fault" divorce; property division; spousal support; child support; child custody; and the family regulation system. The teaching method is a combination of lecture and class discussion, along with in-class small group problem-solving exercises.

Youth and the Law

3 credits

We will consider the way the law responds to the transition from childhood to adulthood across a variety of legal topics. We will consider the ways numeric age and conceptions of maturity influence responses to a range of issues. Topics may include: the treatment of youth in the criminal justice system; the rights of youth to familial or state support in obtaining housing and other material goods; the relationship between youth and commercial actors or other third parties ranging from the infancy doctrine to social media platforms; parental authority and responsibilities in healthcare and educational decision-making; the civic spheres of military service, voting, and jury duty; protective laws such as labor laws; and ages of privilege such as driving and access to alcohol, tobacco, and cannabis. We will read together for the first portion of the course, opening class with all students making quick presentations about the day's readings individually or on teams. As we unpack frameworks underneath youth law, we will consider presentation and paper topics. In the final portion of the course, students will offer oral presentations of their research projects in light of the frameworks we develop. Evaluation will be based on preparation, class participation, presentations, and a paper that follows the presentation. UPPERCLASS WRITING REQUIREMENT: This class may be used to partially satisfy the requirement. GRADING NOTICE: This seminar does not offer the CR/NC option.
