These records include the official documentation of all types of cases filed and tried in Island County Superior Court, a general jurisdiction court. These case types include criminal, civil, domestic relationships (dissolution), probate/guardianship, adoption/parentage, mental illness, juvenile dependency, and juvenile offender. Public access to proceedings involving adoptions, dependency, and mental competency is restricted, and those files are not available online. Requests for adoption, dependency, and mental competency case files should be directed to the Office of the Island County Clerk.

Each case file contains documents filed by both parties and the presiding judge, including awards, complaints, decrees, depositions, orders, pleadings, sentences, and verdicts. Cases are titled and ordered numerically according to the dates that cases are initiated.
