Haw. Dist. Ct. R. Civ. P. 68

At any time more than 10 days before the trial begins, any party may serve upon any adverse party an offer of settlement or an offer to allow judgment to be taken against either party for the money or property or to the effect specified in the offer, with costs then accrued. If within 10 days after the service of the offer the adverse party serves written notice that the offer is accepted, either party may then file the offer and notice of acceptance together with proof of service thereof and thereupon the clerk shall, in accordance with the agreement, enter an order of dismissal or a judgment. An offer not accepted shall be deemed withdrawn and evidence thereof is not admissible except in a proceeding to determine costs. If the judgment finally obtained by the offeree is not more favorable than the offer, the offeree must pay the costs incurred after the making of the offer. The fact that an offer is made but not accepted does not preclude a subsequent offer. When the liability of one party to another has been determined by order or judgment, but the amount or extent of the liability remains to be determined by further proceedings, either party may make an offer of judgment, which shall have the same effect as an offer made before trial if it is served within a reasonable time not less than 10 days prior to the commencement of hearing to determine the amount

or extent of liability.
