There are no shortage of newspaper articles with statements like this:
“Unfortunately the way state laws are written we are not allowed to confirm vital information and vital records,” said Janice Okubo, a spokeswoman for Hawaii’s department of health. “I cannot confirm individual information because that is against the law.”
If Okubo actually said this, she was mistaken. Hawaiian law, while not allowing disclosure of birth records, is fully able to verify them. [Edited to add: I am not really doubting that Okubo said this. I am simply allowing for the possibility that she was misquoted so as not focus any criticism on her. The point is that there is a widespread believe that Hawaii will not verify vital records, and I question that.]
According to §338-14.3, one may obtain “a verification of the existence of a certificate and any other information that the applicant provides to be verified relating to the vital event that pertains to the certificate.” In short, they’ll verify anything you already know.
While obtaining a birth certificate requires a tangible interest, the requirements specified in §338-18(g)(5) for obtaining a verification are much looser, even to the point of allowing a request from
an individual employed, endorsed, or sponsored by a governmental, private, social, or educational agency or organization who seeks to confirm information about a vital event relating to any such record in preparation of reports or publications by the agency or organization for research or educational purposes.
You can’t do this over the phone. You must submit a request and pay a $5 fee. They don’t accept checks.
Update: In 2012 two secretaries of state, from Arizona and Kansas, requested such a verification and received. An attorney in the case of Taitz v. Mississippi Democrat Party also received one.
