Haw. Rev. Stat. § 580-9: Temporary support, etc.

After the filing of a complaint for divorce or separation the court may make such orders relative to the personal liberty and support of either spouse pending the complaint as the court may deem fair and reasonable and may enforce the orders by summary process. The court may also compel either spouse to advance reasonable amounts for the compensation of witnesses and other expenses of the trial, including attorney's fees, to be incurred by the other spouse and may from time to time amend and revise the orders.
