Yes, you must establish residency in HI before you can file. As to how long it takes, that depends on you, and the other party. Unlike some states where there is a mandatory "cooling off period" between filing and finalization, Hawaii only requires that the party have 21 days to respond to the suit for divorce.. It could be done quickly, after the 21 days or it could take much longer, depending on if it truly is uncontested.
