As is true with most states if both parties want a divorce in Hawaii then the procedures get very easy, to get divorced in Hawaii you will probably still want a cheap lawyer or para legal to file the paperwork. Hawaii is considered a no fault state.
The two reasons that a Hawaii marriage is irretrievably broken which the real easy and cheap way is one or both of the parties file a affidavit and the other party doesn't contest it you might not even need to appear in court. The other is after a separation of bed and board for a period which is usually a two year separation again the court could rule the divorce final and send you the final paperwork with out you going to court for a final hearing.
You of course can go the route of lawyers and fighting each other by attorney proxy in a contested divorce, but this can cost a small fortune and really isn't doing anybody any good except for the lawyers. The biggest stumbling blocks to your Hawaiian divorce is going to be lots of property or kids in both of these cases where there is allot of property or kids if you come up together a plan or with a mediator a settlement agreement that you both agree on that makes sense to the judge, who will be using the standard of equitable to both parties, this too can make the divorce process easier and less time consuming which will also translate to a cheaper divorce.
With kids there are some additional requirements for child support and also consoling if the children are between 6 and 18 for all parties in the divorce.
In divorce cases where there are lots of property or children you can still get an inexpensive result if you work together and keep the lawyers time to a minimum, again, if you go down the contested divorce path you are opening pandora box and any thing can happen
There is another major thing to consider and that Hawaii has strict residency requirements for divorce. One of you will have to be a resident for at least 6 months. Once you have that then it figuring out wheather to file in the jurisdiction where you reside or the last jurisdictions that you use to reside together. Basically each of the major islands is a jurisdiction..
