Change of Address Within County of Residence
RCW 9A.44.130
(5)(a) If any person required to register pursuant to this section
changes his or her residence address within the same county, the person
must send signed written notice of the change of address to the county
sheriff within seventy-two hours of moving. If any person required to
register pursuant to this section moves to a new county, the person must
send signed written notice of the change of address at least fourteen
days before moving to the county sheriff in the new county of residence
and must register with that county sheriff within twenty-four hours of
moving. The person must also send signed written notice within ten days
of the change of address in the new county to the county sheriff with
whom the person last registered. The county sheriff with whom the person
last registered shall promptly forward the information concerning the
change of address to the county sheriff for the county of the person's
new residence. Upon receipt of notice of change of address to a new
state, the county sheriff shall promptly forward the information
regarding the change of address to the agency designated by the new
state as the state's offender registration agency.
(b) It is an affirmative defense to a charge that the person failed
to send a notice at least fourteen days in advance of moving as required
under (a) of this subsection that the person did not know the location
of his or her new residence at least fourteen days before moving. The
defendant must establish the defense by a preponderance of the evidence
and, to prevail on the defense, must also prove by a preponderance that
the defendant sent the required notice within twenty-four hours of
determining the new address.
