How to Modify Child Support in Hawaii
Reviewed by DocDraft Legal Team · Hawaii · Last updated September 21, 2026
In Hawaii, a child support modification is a Family Court or Child Support Enforcement Agency (CSEA) order that changes the amount of an existing child support order after a parent's circumstances change. Hawaii gives this a clear benchmark: a material change of circumstances is presumed when the current Hawaii Child Support Guidelines would produce an amount at least ten percent greater or less than the existing order (HRS 576D-7(d)). Support is set by the statewide guidelines tied to each parent's income, so a job loss, a raise, or a new parenting schedule can push the current amount out of line. You can seek a change two ways. You can file a Motion and Declaration to Modify Child Support (Form 1F-P-580 in the First Circuit) with the Family Court that handles your case, or you can ask CSEA to review your order through its administrative process. Either parent can also request a review about every three years without showing a change (HRS 576D-7(e)). Under the agency process, only payments accruing after the other party is served with your request may be modified (HRS 576E-14(b)), so support that already came due cannot be wiped out, and filing early protects you. Keep paying your current order until it is officially changed. Attorney review of your filing is available through DocDraft.

How do I modify child support in Hawaii?
File a Motion and Declaration to Modify Child Support (Form 1F-P-580 in the First Circuit) with the Family Court that issued your order, or ask the Child Support Enforcement Agency to review it. You must show a substantial and material change of circumstances since the last order (HRS 576D-7).
How much does the guideline amount have to change to modify child support in Hawaii?
Hawaii presumes a material change of circumstances when the current guidelines would produce support at least ten percent greater or less than your existing order (HRS 576D-7(d)). You can still argue other substantial changes, but the ten percent guideline difference is the clear statutory benchmark for a modification.
How far back can a child support change go in Hawaii?
Under Hawaii's administrative process, only payments accruing after the other party is served with your request may be modified (HRS 576E-14(b)). A change does not reach back before that notice, so support that already came due cannot be reduced. Filing promptly protects you, and keep paying until the order changes.
Who handles child support modifications in Hawaii?
The Family Court that issued your order handles court modifications, usually in the circuit where your case is filed. The Child Support Enforcement Agency (CSEA), part of the Attorney General's office, can also review and adjust an order it manages through an administrative process. Both apply the Hawaii Child Support Guidelines.
Hawaii child support modification at a glance
In Hawaii, a child support modification is a Family Court or CSEA order that changes the amount of an existing child support order after a parent's circumstances change. Support is set by the statewide Hawaii Child Support Guidelines, and a material change of circumstances is presumed when a new guideline calculation is at least ten percent greater or less than the current order (HRS 576D-7(d)). You can file a Motion and Declaration to Modify Child Support (Form 1F-P-580 in the First Circuit) with the Family Court, or ask the Child Support Enforcement Agency to review your order. Under the agency process, only payments accruing after the other party is served with your request may be modified (HRS 576E-14(b)), so support that already came due cannot be wiped out. Either parent may also request a review about every three years (HRS 576D-7(e)).
Lowering a Hawaii order after a pay cut
Suppose your Hawaii order was set three years ago and your pay was just cut, so a new guideline calculation comes out more than ten percent below your current order, which presumes a material change of circumstances (HRS 576D-7(d)). You complete the Motion and Declaration to Modify Child Support (Form 1F-P-580) with a Financial Information Sheet, file it with the Family Court, and serve the other parent right away. Because only payments accruing after service may be modified (HRS 576E-14(b)), prompt service protects your effective date, and you keep paying the current amount until the judge rules. At the hearing the judge recalculates support under the guidelines and signs a new order going forward. Attorney review of your filing is available through DocDraft.

Frequently Asked Questions
A genuine, involuntary income drop can support a modification, especially if a new guideline calculation is at least ten percent below your current order (HRS 576D-7(d)). You must still file a motion or ask CSEA; support keeps accruing at the old rate until the order changes. Do not simply stop paying.
No. Either parent can file a Motion and Declaration to Modify Child Support on their own, and the other parent is served and can respond. If both parents agree on a new amount, they can submit a stipulation for a judge to approve, checked against the Hawaii guidelines.
After you file Form 1F-P-580, the Family Court sets a hearing, often several weeks to a few months out depending on the circuit and its calendar. An uncontested change or a CSEA administrative review can move faster. Because the change dates from service of your request, filing promptly protects you.
Yes. If the Child Support Enforcement Agency manages your case, you can request a modification in writing and provide current financial information such as pay stubs or tax returns. CSEA reviews the order under the guidelines and can seek an administrative adjustment, and either party may request a hearing.
You can seek a change any time a substantial and material change of circumstances occurs. Separately, either parent has a right to petition the Family Court or CSEA for review and adjustment about once every three years without showing a change (HRS 576D-7(e)). Federal rules back this periodic review.
A modification changes support only going forward. Under the agency process, only payments accruing after the other party is served with your request may be modified (HRS 576E-14(b)). Support that already came due, called arrears, cannot be reduced or erased. Keep paying your current order while your request is pending.
In the First Circuit (Oahu), you file the Motion and Declaration to Modify Child Support (Form 1F-P-580) and a Financial Information Sheet (Form 1F-P-581). Other circuits use their own versions of these forms. The Hawaii State Judiciary website provides the current forms and instructions at no charge.
Filing a motion to modify in Family Court may carry a filing fee, and you can ask the court about a fee waiver if you cannot afford it. Requesting a review through the Child Support Enforcement Agency on a case it manages does not charge you a separate fee.
