uncertifiable

Lacking official confirmation

Not able to be certified or officially declared.

Someone uncertifiable cannot be committed to a psychiatric institution against their will—they don't meet the legal standard for involuntary treatment: He's clearly troubled, but he's uncertifiable.

The word can also mean unable to receive professional certification: The building was uncertifiable under the new safety codes.
