Vital Records: Birth, Marriage and Death
Birth and death records are available through King County Vital Statistics.
These pages provide details on researching historical vital records, as well as tips on obtaining both certified (legal) copies and uncertified copies of vital records. Certified copies have official seals or embossing and are generally used for legal purposes, such as to claim insurance benefits. Uncertified (or "informational") copies may not be sufficient for legal purposes, but they can be useful for many types of research, such as genealogy.
