Family scholars debate whether no-fault regimes have influenced rates of divorce at all. However, a recent analysis has suggested that
"for most of the 32 states that implemented no-fault divorce during the divorce boom (1965-1974)our resultssupport the interpretation that no-fault laws resulted in a substantial number of divorces that would not have occurred otherwise."
-- Sean E. Brotherson and Jeffrey B. Teichert, "Value of the Law in Shaping Social Perspectives on Marriage", 3 U. of Utah Jnl. L. & Fam. Stud. 23, at 47, citing Joseph Lee Rodgers, et al., "Did No-Fault Divorce Legislation Matter? Definitely Yes and Sometimes No," 61 J. Marriage & Fam. 803, 804 (1999).
"One researcher estimated the impact of no-fault divorce legislation may have accelerated state divorce rates upward by twenty to twenty-five percent."

Several States to this day do not have Real No-Fault Divorce as most people think of it, as each requires a seperation period (sometimes lengthy) before a divorce can be granted.
In any case there is no rash of "oppression of women" and abuse in those states.
