Washington is divided into 39 counties. Washington came from what was previously the western part of Washington Territory and was admitted to the Union as the 42nd state in 1889. The first counties were created from unorganized territory in 1845. Eight of the counties were created by Oregon governments prior to the organization of Washington Territory, 26 were created during Washington’s territorial period, and five were created after Washington became a state. Washington State Government is located in Olympia.
Most of the court, probate and land records for various counties were originally housed at the county seat. However, the regional branches of the state archives now house a lot of them. Many counties were grouped together under the same judicial jurisdictions.

Washington Counties with Burned Courthouses
The destruction to Washington courthouses tremendously has a effect on family historians in almost every way. Not only are these kinds of historic buildings ripped from our lifetimes, so are the records they housed: marriage, wills, probate, land records, and others. Once destroyed they’re destroyed forever. Despite the fact that they have been placed on mircofilm, computers and film burn as well. The most heartbreaking side of this is the reason that almost all of our courthouses are destroyed from arsonist. However, don’t assume all records were lost. Numerous Washington counties have dealt with a loss of records due to courthouse fires, floods, and theft.
- Clark County Courthouse and Jail destroyed by fire on February 25, 1890. Many county records were destroyed, including probate records, Superior and District court records, and records of the Sheriff, Superintendent of Schools and Surveyor’s office. The County Auditor’s records were safe from fire.
