You will have to sue for quiet title and/or ejectment. You cannot use the unlawful detainer procedures that are commonly used with a tenant who pays rent under a lease. You must give notice to your daughter that her "tenancy at will" is terminated, and that she has 60 days to vacate the premises (the law actually requires only a "reasonable time to vacate," but 60 days is probably reasonable, under the circumstances.
If she does not leave, you will have to sue as previously described. Regrettably, this type of lawsuit is a big pain in the ***, because of the unusual requirements. Unfortunately, it's the only way that has been allowed by the Washington courts. See Turner v. White, 115 Wash.App. 634.
