Unlike Glen, I am not an attorney so I guess I can give this layperson pointer:
The Hawai'i Revised Statutes are on line for you to peruse, and here is part of the SOL section:
http://www.capitol.hawaii.gov/hrscurrent..._0657-.htm
This is the Table of Contents for different kinds of actions:
and this is one section, on breach of contract
http://www.capitol.hawaii.gov/hrscurrent...7-0001.htm
quote:
PART I. PERSONAL ACTIONS
ยง657-1 Six years. The following actions shall be commenced within six years next after the cause of action accrued, and not after:
(1) Actions for the recovery of any debt founded upon any contract, obligation, or liability, excepting such as are brought upon the judgment or decree of a court; excepting further that actions for the recovery of any debt founded upon any contract, obligation, or liability made pursuant to chapter 577A shall be governed by chapter 577A;
I only quoted a tiny bit there, not to give you "the answer" but just as a pointer for a place to start reading. Like Glen said, you weren't specific enough about what it is your cause of action would be; if you look at this paragraph you get an idea of how specific the law gets.
I would agree you need to ask an attorney, as SOL isn't something you want to miss out on.
I personally am one of those people who likes to find the law and read it for myself, but that's me. At least I like to find as much as I can for free before I start paying someone by the hour. So if you too like to do research here is one tool.
By the way, anyone on island can access a hard copy of the Hawai'i statutes at the Law Library in the State Building in the Lagoon Center. I went there once and it's not too intimidating. It's a far cry from the beautiful Alameda County Law Library that I used to go to, but it's so much better than that moldy room they call a law library in Kealakekua.
