Wash. Rev. Code § 63.60.010
Every individual or personality has a property right in the use of his or her name, voice, signature, photograph, or likeness. Such right exists in the name, voice, signature, photograph, or likeness of individuals or personalities deceased before, on, or after June 11, 1998. This right shall be freely transferable, assignable, and licensable, in whole or in part, by any otherwise permissible form of inter vivos or testamentary transfer, including without limitation a will or other testamentary instrument, trust, contract, community property agreement, or cotenancy with survivorship provisions or payable-on-death provisions, whether the will or other testamentary instrument, trust, contract, community property agreement, or cotenancy document is entered into or executed before, on, or after June 11, 1998, by the deceased individual or personality or by any subsequent owner of the deceased individual's or personality's rights as recognized by this chapter; or, if none is applicable, then the owner of the rights shall be determined under the laws of intestate succession applicable to interests in intangible personal property. The property right does not expire upon the death of the individual or personality, regardless of whether the law of the domicile, residence, or citizenship of the individual or personality at the time of death or otherwise recognizes a similar or identical property right. The right exists whether or not it was commercially exploited by the individual or the personality during the individual's or the personality's lifetime. The rights recognized under this chapter shall be deemed to have existed before June 11, 1998, and at the time of death of any deceased individual or personality or subsequent successor of their rights for the purpose of determining the person or persons entitled to these property rights as provided in RCW 63.60.030. This chapter is intended to apply to all individuals and personalities, living and deceased, regardless of place of domicile or place of domicile at time of death.
