Like many legal and social thinkers of their day, novelists such as Daniel Defoe, Samuel Richardson, Frances Burney, Eliza Fenwick, and Amelia Opie imagine marriage as a public institution subject to regulation by church and state rather than a private agreement between two free individuals. Through recurring scenes of infidelity, fraud, and coercion as well as experiments with narrative form, these writers show the practical and ethical problems that result when couples attempt to establish and dissolve unions simply by exchanging consent. Even as novelists seek to shore up the legal regulation of marriage, however, they contest the specific forms that these regulations take. In recovering novelists’ engagements with the nuptial controversies of the Enlightenment, challenges longstanding accounts of domestic fiction as contributing to sharp divisions between public and private life and as supporting the traditional, patriarchal family. At the same time, the book counters received views of law and literature, highlighting fiction’s often simultaneous affirmations and critiques of legal authority.
