HRS §490:8-206
When a stock certificate is incomplete or changed
This section explains what happens when a stock certificate is missing information or has been changed. If it is incomplete, someone can fill in the blanks as allowed, and a buyer who paid for it without knowing about mistakes can still enforce it. If it was altered, it is only enforceable according to its original terms.

The statute, as written — Completion or alteration of security certificate
(a) If a security certificate contains the signatures necessary to its issue or transfer but is incomplete in any other respect: (1) Any person may complete it by filling in the blanks as authorized; and (2) Even if the blanks are incorrectly filled in, the security certificate as completed is enforceable by a purchaser who took it for value and without notice of the incorrectness. (b) A complete security certificate that has been improperly altered, even if fraudulently, remains enforceable, but only according to its original terms.
