Lump sum alimony in Hawaii is a single, one-time spousal support payment that replaces ongoing monthly alimony, authorized under the family court's broad discretion in Haw. Rev. Stat. § 580-47. Hawaii courts most often award lump sum buyouts when the paying spouse holds substantial assets but lacks steady income, and a properly drafted alimony buyout agreement can permanently end future modification claims.
Hawaii has no statutory formula for alimony of any kind. Instead, family courts weigh 13 statutory factors under Haw. Rev. Stat. § 580-47 to decide whether support is warranted, then apply the same factors to set the amount and duration. A lump sum payment converts that calculated stream of monthly support into one present-value figure. Because Hawaii is a no-fault, equitable-distribution state, courts also frequently use an unequal property split in lieu of alimony, which functions like a one time alimony payment even when it is not formally labeled support.

What Is Lump Sum Alimony in Hawaii?
Lump sum alimony in Hawaii is a single fixed payment of spousal support, sometimes called "alimony in gross," that discharges the paying spouse's entire support obligation at once instead of through monthly checks. Hawaii case law has recognized this form of support for decades, with reported decisions addressing "alimony in gross: when warranted, computation" (40 Haw. 644). The amount is governed by the same 13 factors in Haw. Rev. Stat. § 580-47.
Unlike periodic alimony, a lump sum award is generally fixed and non-modifiable once paid, which is its primary attraction for spouses who want a clean financial break. Hawaii courts most commonly order a lump sum when the paying party lacks a steady paycheck but holds significant assets — an annuity, business equity, intermittent wages, or retirement accounts. In one reported decision, a single lump sum payment representing a spouse's interest in the other's federal civil service retirement was awarded rather than a percentage of each monthly payment as received (1 Haw. App. 288, 618 P.2d 754). The buyout converts the projected total of monthly support into one present-day number, which the parties or the court may discount to present value. Because Hawaii imposes no rigid alimony formula, the lump sum figure reflects negotiation and judicial discretion rather than a statutory multiplier.
How Hawaii Courts Decide Whether to Award Alimony
Hawaii alimony is never automatic; a family court awards support only after finding that one spouse needs financial help and the other has the ability to pay, applying the 13 factors in Haw. Rev. Stat. § 580-47(a). Because Hawaii is a no-fault state under Haw. Rev. Stat. § 580-41, marital misconduct such as adultery is not a statutory factor and typically does not affect the award.
The statute lists 13 considerations the court must weigh, including the financial resources of each party, the duration of the marriage, the standard of living established during the marriage, the age and health of both parties, the vocational skills and employability of the party seeking support, and the probable duration of the need for support. Courts use these factors twice: first to decide whether any alimony is appropriate, then to set the amount and duration. Hawaii recognizes four practical categories of support — temporary support during the case under Haw. Rev. Stat. § 580-9, plus transitional, rehabilitative, and permanent post-divorce alimony. Rehabilitative short-term support is the most common award in Hawaii, designed to fund job training or education until the recipient becomes self-supporting. A lump sum is a payment method that can apply to any of these categories, converting what would otherwise be monthly transitional or rehabilitative support into one fixed sum.
Lump Sum vs Monthly Alimony in Hawaii
Monthly alimony is the default in Hawaii, with payments often routed through the Child Support Enforcement Agency, while lump sum alimony delivers the full obligation in one payment and is comparatively rare. The choice between lump sum vs monthly alimony affects tax exposure, modification rights, default risk, and the recipient's ability to plan, so each option carries distinct trade-offs under Haw. Rev. Stat. § 580-47.
The table below compares the two structures across the factors Hawaii spouses weigh most heavily when negotiating an alimony buyout agreement.
| Feature | Lump Sum (Buyout) | Monthly Periodic Alimony |
|---|---|---|
| Payment structure | One fixed payment | Recurring monthly payments |
| Modifiable later | No, if non-modification agreed in writing | Yes, on material change (HRS § 580-47(d)) |
| Terminates on remarriage | No, once paid | Yes, automatically unless agreed otherwise |
| Default/collection risk | Low — paid upfront | Higher — depends on ongoing income |
| Best when payer has | Substantial assets, irregular income | Steady salary or wages |
| Federal tax (post-2018) | Not deductible / not taxable | Not deductible / not taxable |
| Court frequency in Hawaii | Rare | Common |
| Future court involvement | Generally none | Possible repeated motions |
A completed lump sum buyout removes the automatic termination-on-remarriage rule that applies to monthly support. Under Hawaii practice, periodic alimony automatically ends when the recipient remarries, and the remarried spouse must file notice within 30 days or risk paying back support, costs, and fees. A one time alimony payment that is already disbursed is generally immune from that contingency.
How Lump Sum Alimony Is Calculated in Hawaii
Hawaii has no statutory formula for calculating lump sum alimony; the figure is derived from negotiation or judicial discretion under the 13 factors in Haw. Rev. Stat. § 580-47, often by estimating the monthly amount, multiplying by the likely duration, and discounting to present value. One informal benchmark some Hawaii practitioners reference is one year of support for every three years of marriage, though no statute requires it.
The practical calculation usually proceeds in steps. First, the parties estimate what monthly support a court would likely order based on the recipient's need and the payer's ability to pay. Second, they estimate the probable duration — a few months for transitional support, a few years for rehabilitative support tied to a training plan, or longer for a long marriage. Third, they multiply the monthly figure by the number of months to reach a gross total. Fourth, because the recipient receives the money now rather than over time, the parties may apply a present-value discount, which reduces the lump sum below the simple gross total. Courts retain broad discretion to adjust these numbers and may even waive an equalization payment where valid considerations support deviation, as Hawaii appellate courts have affirmed (134 Haw. 431, 341 P.3d 1231 (2014)). Because no formula binds the court, the final buyout number is heavily fact-dependent and benefits from a clear written settlement.
Using Property Division as an Alimony Buyout in Hawaii
Hawaii family courts can allocate an unequal share of marital property in lieu of alimony, effectively achieving an alimony buyout through the property settlement rather than through a support order, under the equitable-distribution authority of Haw. Rev. Stat. § 580-47. For example, a court may award 60% of income-producing assets to a lower-earning spouse with limited future earning capacity instead of ordering ongoing monthly support.
Hawaii is an equitable-distribution state, meaning the court divides community, joint, and separate property in a just and equitable manner — not necessarily 50/50. Because the same statute, Haw. Rev. Stat. § 580-47, governs both property division and spousal support, the court can blend the two: giving one spouse the marital home, a larger retirement share, or a cash equalization payment in exchange for waiving or reducing alimony. This property-based approach is often cleaner than a standalone support buyout because property transfers between divorcing spouses are not taxable events and the transfer is final once recorded. Hawaii appellate courts have upheld significant deviations from equal division when valid and relevant considerations justify them, including waiving a wife's equalization payment where the record supported it (134 Haw. 431, 341 P.3d 1231 (2014)). Spouses negotiating a buyout should consider whether structuring the deal as a property offset rather than labeled alimony produces a better tax and finality outcome.
Tax Treatment of Lump Sum Alimony in Hawaii
Lump sum alimony in Hawaii is neither tax-deductible for the payer nor taxable income for the recipient, because the federal Tax Cuts and Jobs Act of 2017 eliminated the alimony deduction for all divorce agreements executed after December 31, 2018, and Hawaii conformed its state tax treatment under Act 27 (2018 Session Laws).
This tax rule applies equally to monthly and lump sum support, so the timing of payment does not change the federal or state tax result for divorces finalized in 2026. For agreements executed on or before December 31, 2018, the old rules may still apply — the payer could deduct alimony and the recipient reported it as income — but those grandfathered cases are increasingly rare. When a buyout is structured as a property transfer rather than as support, a different and generally favorable rule applies: transfers of property between spouses incident to divorce are not taxable events under federal law, so neither spouse recognizes gain or loss on the transfer itself. This is one reason many Hawaii couples prefer to characterize an alimony buyout as a property equalization payment. However, the recipient may face capital-gains tax later when selling an appreciated asset received in the settlement, so the carryover basis must be analyzed before agreeing to any one time alimony payment structured as property.
Filing Costs and Residency for a Hawaii Divorce
The filing fee for divorce in Hawaii is $215 for cases without minor children and $265 for cases involving minor children, with the extra $50 covering the mandatory parent education program. To file, you must be domiciled in Hawaii at the time of filing under Haw. Rev. Stat. § 580-1, and the court cannot grant a final decree until you have been continuously domiciled in the state for at least 6 months.
Hawaii overhauled its residency rules through Act 69 (2021), which eliminated the older requirement that a person live in-state for 6 months before filing. Under the current framework, domicile — physical presence plus intent to remain indefinitely — is what matters at filing, while the 6-month continuous-domicile requirement attaches to the decree rather than the petition. Hawaii operates four family court circuits: First Circuit (Oahu), Second Circuit (Maui), Third Circuit (Hawaii Island), and Fifth Circuit (Kauai), and you file where you are domiciled. Low-income filers can request a fee waiver using Form 1-P (Application to Proceed Without Prepayment of Fees); for 2026, the income threshold sits near 125% of the federal poverty guidelines, roughly $20,000 for a single filer, and an approved waiver brings court costs to $0.

Making a Lump Sum Alimony Agreement Non-Modifiable
A lump sum alimony buyout in Hawaii becomes truly final only when the spouses agree in writing that neither party can later seek modification; without that written non-modification clause, either spouse retains the right to ask the court for review under Haw. Rev. Stat. § 580-47(d) upon a material change in circumstances. A properly drafted alimony buyout agreement should therefore state expressly that the payment is in full satisfaction of all support and is non-modifiable.
Hawaii law gives spouses substantial freedom to design their own support terms, even terms a court would not impose on its own. Couples can agree to an amount, duration, and payment method that differs from the statutory default and can foreclose future modification entirely. This is the central advantage of a lump sum: once the money changes hands and the agreement bars modification, the matter is closed. The agreement should address several points to be enforceable and durable: the exact dollar amount, the date of payment, an explicit waiver of future modification, language that the payment satisfies all past, present, and future support claims, and treatment of the remarriage and death contingencies that would otherwise terminate periodic alimony. Because Haw. Rev. Stat. § 580-47(d) allows modification absent a written waiver, omitting this clause can leave a paying spouse exposed to a future support claim even after a large buyout. A Hawaii family law attorney should draft or review the non-modification language before signing.
When a Lump Sum Buyout Makes Sense in Hawaii
A lump sum alimony buyout makes the most sense in Hawaii when the paying spouse has access to significant assets but unpredictable income, when both spouses want a permanent financial break, or when the recipient prefers guaranteed money now over the default risk of monthly payments collected through wage withholding. Hawaii courts most often order lump sums precisely in the asset-rich, income-irregular scenario.
Several situations favor a buyout. A self-employed payer or one with intermittent wages may struggle to make reliable monthly payments, so courts and parties may prefer a one-time settlement funded from existing assets. A recipient worried about collection or future nonpayment gains certainty by receiving the full amount upfront. Spouses who want to avoid repeated trips to family court — and the legal fees that accompany modification motions — value the finality a non-modifiable lump sum provides. Conversely, a buyout is rarely wise when the payer's only resource is a steady salary, when the supported spouse needs ongoing monthly cash flow to cover living expenses, or when neither side can accurately predict the recipient's future need. Because the decision turns on individual finances, tax position, and risk tolerance, spouses should model both lump sum vs monthly alimony scenarios with a Hawaii family law attorney and, where significant assets are involved, a financial advisor before committing to either structure.
