The member, if married, must provide the spouse's written consent to the option selected under WAC 415-100-055. If a married member does not provide spousal consent, the department will pay the retired member a joint and one-half survivor benefit allowance and record the member's spouse as the survivor, in compliance with RCW 2.10.146(2). "Spousal consent" means that the married member's spouse consents to the retirement option selected by the member. (The spouse's notarized signature on a completed retirement application constitutes spousal consent.)
