The Fourth Edition of this popular casebook by Professors Wadlington & O'Brien has made several changes in the sequence of materials. Divorce & economic problems of dissolution have been moved forward to Chapters IV & V from the close of the book. A substantial number of provisions from the California Family Code, as well as other new statutes, have been included. The notes have been expanded to include material such as San Francisco's domestic partnership agreement & Hawaii's current approach(es) to same-sex marriage. New cases range from informal marriage to grandparent visitation rights, international custody disputes, ERISA preemption (Boggs v. Boggs), property settlement agreements, & policy on posthumous use of frozen semen.
