Is it permissible for a minor to sign a cremation authorization form in Washington State?

In Washington State, a cremation authorization form must be signed by a legal adult, which is why the correct answer highlights that only a legal adult can provide authorization. This is grounded in the legal understanding that minors do not have the capacity to enter into contracts or provide binding authorizations regarding dispositions of human remains. The law is structured in such a way to ensure that the decision making around cremation—an irreversible action—requires the consent of an individual who has the legal standing to undertake such responsibilities.

Thus, while the notion of parental consent implies a route for minors to be involved, the law specifically mandates that the signature must be from a legal adult, reinforcing the protection of minors in such sensitive matters. The other options suggest permissions or scenarios that do not align with the legal framework governing such decisions in Washington State.
