As reported in The San Francisco Chronicle, retired San Francisco judge Isabella Horton Grant died of cancer on Saturday at age 87.

Judge Grant made many contributions to family law, including her participation in the drafting and passage of California’s no-fault divorce rule, which went into effect January 1, 1970 with the enactment of the Family Law Act of 1969.

Prior to the enactment of California’s no-fault divorce rule, the moving party in a divorce was a plaintiff who charged the other spouse, as a defendant, with being “at fault” for the divorce for reasons such as adultery, abuse, etc.
