"...the legislature's omission of any language addressing the legal rights of parties to familial relationships such as the one presented here does not imply the complete denial of remedy but rather leaves the matter to be resolved by common law. In re Parentage of L.B., 121 Wn. App. at 475-76. Then, relying on the persuasive authority of other state courts that have recognized the common law rights of de facto parents, the court held that a common law claim of de facto or psychological parentage exists in Washington separate and distinct from the parameters of the UPA* and that such a claim is not an unconstitutional infringement on the parental rights of fit biological parents. Id. at 485. The Court of Appeals held that a de facto parent may prove the existence of a parent-child relationship by presenting evidence sufficient to prove:
(1) the natural or legal parent consented to and fostered the parent-like relationship;
(2) the petitioner and the child lived together in the same household;
(3) the petitioner assumed obligations of parenthood without expectation of financial compensation; and
(4) the petitioner has been in a parental role for a length of time sufficient to have established with the child a bonded, dependent relationship parental in nature."
