Legal Question in Real Estate Law in Hawaii

The question is a bit vague. However, the first thing you need to do is make a detailed list of all of the items that are there. That way there is no dispute later about "missing" items.

See if that works. If not you will need to comply with Hawaii Abandonment Law.
