Frequently Asked Questions
Child Support in Hawaii
Discover what you need to know about Child Support Laws in Hawaii.
Hawaii calculates child support using the Hawaii Child Support Guidelines, which follow an income-shares model. The goal is to estimate what parents would have spent on the child if they were living together.
Number of Children
Both parents’ gross incomes
Each parent’s proportional share of the combined income
For an estimate tailored to your situation, you can use the Deliberately.ai Hawaii's child support calculator above, but only a court order is legally binding.
Child support in Hawaii is influenced by each parent’s income, the number of children, and guideline adjustments. Courts may also consider work-related childcare expenses, health insurance premiums for the child, and certain extraordinary expenses. If income is inconsistent, self-employment is involved, or expenses are disputed, the calculation can become more detailed.
There is no one-size-fits-all amount. The total depends on both parents’ financial information and how the Hawaii guideline worksheet applies to your case. To get a reliable estimate before filing or negotiating, use the Deliberately.ai calculator above—just remember the court has final authority over the support order.
In most cases, child support ends when the child turns 18. However, if the child is still enrolled in high school, support may continue until graduation or age 19, whichever comes first.
Not always. While Hawaii law sets general termination rules, you should confirm the specific terms in your court order. If payments are being collected through wage withholding or the Child Support Enforcement Agency (CSEA), proper procedures may be needed to stop or adjust payments.
Yes. Hawaii allows child support to be modified when there has been a material change in circumstances—such as a change in income or financial needs of the child. Modifications generally apply going forward from the date a motion is filed.
Uncontested modifications may be resolved within a few weeks to a few months. Contested cases—especially those involving disputed income, self-employment, or requested deviations—can take longer depending on court schedules and documentation.
Hawaii generally considers gross income, which may include wages, bonuses, commissions, overtime, and self-employment income. If a parent is voluntarily unemployed or underemployed, the court may consider earning capacity when calculating support.
Failure to pay child support can result in enforcement actions such as wage withholding, tax refund interception, license suspension, liens, and court proceedings. As arrears grow, enforcement measures may increase.
Arrears remain owed until paid in full. Even after the regular child support obligation ends, unpaid balances may continue to be enforced through available collection methods.
In certain cases, willful failure to pay child support may lead to contempt proceedings or other penalties. Courts can impose fines or other consequences if nonpayment is determined to be intentional. If you are facing enforcement action, legal advice is strongly recommended.
Yes. Wage withholding is common in Hawaii child support cases. Additional enforcement tools may include tax intercepts, liens, and other collection methods through the Child Support Enforcement Agency (CSEA).
Not automatically. Parenting time is considered in the guidelines, but income differences between parents remain an important factor. Shared custody does not eliminate child support and may still result in an obligation depending on financial circumstances.
Child support generally ends at the statutory termination age (18, or up to 19 if still in high school). College support is not automatic under Hawaii guidelines. Continued support for a child with qualifying disabilities may follow different legal standards.
Parents cannot privately waive court-ordered child support without court approval. Child support is considered the right of the child, and any change must be reviewed and approved by the court.
A lawyer is not required for straightforward or uncontested cases. However, legal representation is strongly recommended when income is disputed, self-employment is involved, arrears exist, or a guideline deviation is requested.
You will typically need recent pay stubs, tax returns (especially for self-employment), proof of health insurance costs for the child, childcare receipts, and copies of existing court orders. Incomplete or inconsistent financial records can delay the process.
Child support cases are handled through Hawaii family courts or through the Hawaii Child Support Enforcement Agency (CSEA) for establishment and enforcement. If parentage, income, or expenses are likely to be contested, consulting an experienced Hawaii family lawyer before filing can help you avoid costly mistakes.
