When California signed the first no-fault divorce law in 1969, the pitch was humane and tidy: spare couples the theater of fault, let unhappy people leave, and the kids will be fine because adults will be happier. Half a century of outcomes data tells a more complicated story, and a growing chorus of family scholars across the political spectrum is finally willing to say so.
This is not a call to trap people in violent marriages. It is a question about what we built when we made marriage the easiest contract in American law to walk away from.
The economic shock fell on women
The original sales pitch assumed symmetry. In practice, no-fault rewrote bargaining power inside the marriage. Lenore Weitzman’s research and follow-up work by Richard Peterson found women’s household income dropped sharply post-divorce while men’s recovered or rose. Stay-at-home parents lost the leverage to negotiate alimony, and courts shifted toward “rehabilitative” support that assumes a woman with a fifteen-year career gap can simply re-enter the labor market. The result was a generation of older divorced women cycling onto public benefits. Even today, women over 50 going through “gray divorce” see roughly a 45% drop in standard of living, while men see closer to 21%. That is not liberation. It is a wealth transfer dressed up as freedom.
Children paid a quieter price
Researchers like Paul Amato and Sara McLanahan documented that children of divorce, controlling for income, show measurably worse outcomes on schooling, mental health, and adult relationship stability. The effect is small per-child but enormous in aggregate. Importantly, the harm clusters in low-conflict divorces, the exact marriages no-fault made easiest to dissolve. High-conflict households produce kids who often improve after a split. Low-conflict ones, where parents are simply bored or restless, produce kids who lose stability for reasons they cannot understand. We told ourselves the children would adapt. The longitudinal data says many of them never quite do.
The incentives reshape marriage itself
Contracts that can be voided unilaterally without cause are not really contracts. Once no-fault was universal, the rational move for the higher-earning, lower-investing spouse changed. Why fully commit when exit is costless? Economists Justin Wolfers and Betsey Stevenson found suicide rates among married women fell after no-fault, which is a real and important benefit. But marriage rates also fell, cohabitation rose, and the average age of first marriage climbed past 30. People sense, correctly, that the institution offers less protection than it used to. So they hedge.
The takeaway
Reasonable people can defend no-fault for the worst marriages while admitting it was a blunt instrument. Mutual-consent divorce, mandatory waiting periods with kids involved, and stronger alimony standards would preserve the escape hatch without making marriage the only contract you can shred over breakfast. Calling that conversation reactionary is how we avoid having it. The evidence has been in for a while. We just did not want to read it.
