The following announcement was written by the Seattle Genealogical Society:
The Seattle Genealogical Society is proud to announce the availability of a huge database, the SGS King County Court Cases Index, 1881-1980, or KC3I for short. This index contains over 1.7 million records. Of these, divorces and other end-of marriage cases comprise over 700,000 of the entries, and probate and similar cases account for nearly 300,000 more.
The KC3I was created over a ten year period by a small but resolute group of SGS volunteers from over 100 boxes of index cards from the Chicago Title Company. It is an index of ALL King County court cases that could potentially affect property rights, and therefore the title to property from before 1881 through 1980. In addition to divorce and probate cases, the KC3I also includes all King County court cases involving name changes, community property agreements and guardianships, among others. Nearly 80,000 hours of volunteer time went into the creation of the KC3I.
