The King County Court Cases Index, 1881-1980 (KC3I)

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.

As its name suggests, the KC3I is an index only. It does not contain abstracts or summaries of these cases. A search of this index:

a) informs you if your ancestor was a party in one or more cases during this period;
b) lists the date and a few other details about each case (such as date of marriage or death, wife’s maiden name, etc.); and
c) provides you with the case number and date of each case.

Once you have the case numbers, you can then obtain the complete case records from the King County Court Clerk’s office.

Anyone with ancestors who lived in King County, Washington between 1850 and 1980 should be aware of this index, which is not available anywhere else, other than in the King County Superior Court Clerk’s office.
