From Genesis to genetic engineering, societyâ€™s efforts to fashion legal structures for family relationships are encyclopedic. The Fifth Edition of this casebook makes no attempt to address each and every event in that evolution; rather the book is designed to provide cases, statutes and materials that will offer teachers the opportunity to incorporate the myriad of nuances and developments into their own courses. The materials trace trends and principles which form a bedrock of family law in the states and increasingly, federal interaction. Even though each state has its own body of law, the federal judiciary and Congress increase their roles to meet the pressing needs of welfare reform and child protection, to identify only a small scope. This federal presence, together with Uniform Acts and international treaties, provide the fabric of an ever-changing family law in the United States.
