Even during the initial period when divorce rates were increasing, several positive trends accompanied the transition to no-fault. The economists Betsey Stevenson and Justin Wolfers of the University of Pennsylvania report that states that adopted no-fault divorce experienced a decrease of 8 to 16 percent in wives’ suicide rates and a 30 percent decline in domestic violence.

Social changes always involve trade-offs. Unilateral divorce increases the risk that a partner who invests in her (or more rarely, his) marriage rather than in her own earning power, and does not engage in “bad behavior,” may suffer financially as well as emotionally if the other partner unilaterally ends the marriage. When courts have not taken this sacrifice into account in dividing property, homemakers have been especially disadvantaged.

Fairer division of marital assets can reduce the severity of this problem. And fault can certainly be taken into account in determining spousal support if domestic violence or other serious marital misbehavior has reduced the other party’s earning power.

Still, the ability of one partner to get a divorce over the objections of the other may create an atmosphere in which people think twice before making sacrifices that will be costly if the marriage ends. Professor Stevenson found that in states that allow unilateral divorce, individuals tend to be slightly less likely to invest in marriage-related capital, like putting the partner through school, and more likely to focus on building individual, portable capital, like pursuing their own education or job experience.

Unilateral divorce has decreased the bargaining power of the person who wants the marriage to last and has not engaged in behavior that meets the legal definition of fault. On the other hand, it has increased the bargaining power of the person who is willing to leave. So while some marriages end more quickly than they otherwise would, other couples enter marital counseling because one partner’s threat of divorce convinces the other that it is time to work seriously on the relationship.

Contrary to conventional wisdom, it is more often the wife than the husband who is ready to leave. Approximately two-thirds of divorces  including those that come late in life  are initiated by wives. Paula England, a senior fellow at the Council on Contemporary Families, found that surveys that separately ask divorced wives and husbands which one wanted the divorce confirm that more often it was the woman who wanted out of the marriage. This jibes with research showing that women are physiologically and emotionally more sensitive to unsatisfactory relationships.
