 Finally, a rationale for restricting the terms of exit from marriage (but not for supporting it as a form of life) is the protection of women and children following divorce. Women in gender-structured marriages, particularly if they have children, tend to become economically vulnerable. Statistically, married women are more likely than their husbands to work in less well-paid part-time work, or to give up paid work entirely, especially to meet the demands of child-rearing. Thus, following divorce, women are likely to have a reduced standard of living, even to enter poverty. Because these patterns of choice within marriages lead to inequalities between men and women, property division on divorce is a matter of equality or equal opportunity, and so a just law of divorce is essential to gender justice (Okin 1989, Chapters 7 and 8; Rawls 1997, 787–794; Shanley 2004, 3–30; Waldron 1988, and see 5.1). However, it can still be asked why a law recognizing marriage as such should be necessary, as opposed to default rules governing property distribution when such gender-structured relationships end (Sunstein and Thaler 2008, Chambers 2017). Indeed, placing these restrictions only on marriage, as opposed to enacting general default rules, may make marriage less attractive, especially to men, and hence be counter-productive, leaving women more vulnerable.
