There is no law in WA that requires a living person to record, file, or do something else with the government for the person's will.
The county's recorder's office does accept a will for recording if someone wants to have the will recorded.
WA superior courts have a program in which the clerks of the courts will accept original wills of still living persons for safekeeping. The clerks charge a fee each time the will is put in or taken out of the clerk's office.
Wills must follow statutory procedures to be accepted by the court.
You should review the specific facts with your attorney to make sure your will will be accepted by the courts when needed.
