Hawaii Alimony / Spousal Support Estimator

Hawaii has no formula or guideline for calculating spousal support. Under HRS § 580-47(a), family court judges use broad discretion, evaluating 13 statutory factors including each spouse's financial resources, the marriage duration, the marital standard of living, and the requesting spouse's ability to become self-supporting. The court must first determine that one spouse needs support and the other can afford to pay.

Hawaii courts award four types of spousal support: temporary support under HRS § 580-9 during the pending dissolution of marriage, short-term transitional support lasting as little as 6 months, rehabilitative support (the most common type, requiring a court-approved plan for self-sufficiency), and permanent support for spouses unable to work due to age or disability. Rehabilitative support typically lasts until the recipient completes education or job training.

Hawaii law sets no fixed duration limits for spousal support — the length depends on the type awarded and individual circumstances. Transitional support may last as briefly as 6 months, while rehabilitative support continues until the recipient becomes self-supporting per a court-approved plan. Permanent support, though rare, can last indefinitely. Under HRS § 580-51, all spousal support automatically terminates upon the recipient's remarriage unless the divorce decree specifically provides otherwise.

HRS § 580-47(a) requires family courts to evaluate 13 factors, including: each party's financial resources, ability to meet needs independently, duration of the marriage, marital standard of living, age and health of each spouse, custodial responsibilities for children, vocational skills and employability, and the paying spouse's ability to support both parties. The court also considers concealment of assets or income and the probable duration of the requesting spouse's need.

Hawaii spousal support orders can be modified when either party demonstrates a material change in circumstances — such as a significant increase or decrease in income, job loss, or serious health changes. The requesting party must file an affidavit with the family court explaining the changed circumstances. However, if both spouses signed a written agreement waiving modification rights and the court approved it, modification may not be available.

Marital misconduct, including adultery, is generally not a factor in Hawaii spousal support determinations. The 13 statutory factors under HRS § 580-47(a) focus primarily on financial circumstances — income, assets, earning capacity, and the standard of living during the marriage. The only exception is when misconduct caused direct, significant financial harm to marital assets, such as dissipation of funds on an extramarital relationship.

For dissolutions of marriage finalized after December 31, 2018, alimony payments are neither tax-deductible for the payer nor reportable as taxable income for the recipient under both federal law (Tax Cuts and Jobs Act) and Hawaii state tax law. For pre-2019 divorce agreements, the payer may still deduct alimony and the recipient must report it as income. Hawaii Form N-15 still includes an alimony deduction line for qualifying pre-2019 agreements.

Hawaii allows spousal support waivers in prenuptial agreements under the Hawaii Uniform Premarital Agreement Act (HRS Chapter 572D). However, Hawaii courts retain discretion to strike an alimony waiver if enforcing it would be unconscionable or would leave the lower-earning spouse dependent on public assistance. The court evaluates fairness at the time of the dissolution, not just when the agreement was signed. Both parties should have independent legal counsel when drafting a prenup with an alimony waiver.
