Adultery does not affect the grounds for divorce, alimony awards, or property division in Hawaii. Under HRS § 580-41, Hawaii operates as a strictly no-fault divorce state where the only recognized ground is that the marriage is irretrievably broken. Hawaii courts explicitly prohibit judges from considering marital misconduct, including infidelity, when determining spousal support or dividing marital assets under HRS § 580-47. The filing fee for divorce in Hawaii is $215 for couples without minor children or $265 for couples with minor children as of March 2026.

Hawaii Is a Strictly No-Fault Divorce State
Hawaii does not recognize adultery as grounds for divorce. Under HRS § 580-41, the only way to obtain a divorce in Hawaii is to demonstrate that the marriage is irretrievably broken, meaning there is no reasonable possibility of reconciliation. You do not need to prove that your spouse committed any wrongdoing, including infidelity, cruelty, or abandonment.
Hawaii recognizes four no-fault grounds for divorce under HRS § 580-41:
- The marriage is irretrievably broken (most common ground, used in approximately 95% of Hawaii divorces)
- The parties have lived separate and apart for two or more continuous years without reasonable likelihood of reconciliation
- A court-ordered legal separation has expired without reconciliation
- A separate maintenance decree has been in effect for two or more years without reconciliation
Under HRS § 580-42, both spouses may submit an affidavit stating the marriage is irretrievably broken. If neither spouse contests this assertion, the court may waive a hearing entirely and grant the divorce based on the sworn affidavit alone. This streamlined process allows uncontested divorces in Hawaii to finalize in as little as 6 to 10 weeks.
Adultery Does Not Affect Alimony in Hawaii
Hawaii courts cannot consider adultery or any other form of marital misconduct when determining spousal support awards. Under HRS § 580-47(a), the family court is required to evaluate 13 statutory factors when deciding whether to award maintenance, and marital fault is explicitly excluded from this analysis. A cheating spouse in Hawaii will not receive reduced alimony, and a faithful spouse will not receive enhanced support due to infidelity.
The Hawaii Supreme Court addressed this issue directly, stating that examining marital fault is an old-fashioned approach that is unquestionably not in keeping with the modern trend. The court concluded that fault is no longer a consideration in assessing alimony obligations between spouses.
The 13 factors Hawaii courts must consider for spousal support under HRS § 580-47(a) include:
- Financial resources of both parties after property division
- Ability of the paying spouse to meet their own needs while paying support
- Standard of living established during the marriage
- Duration of the marriage (marriages under 5 years rarely result in alimony; marriages over 15 years frequently include support)
- Age and physical and emotional condition of each party
- Earning capacity of the party seeking support
- Time necessary for the receiving spouse to acquire education or training for suitable employment
- Ability of the receiving spouse to become self-supporting
- Tax consequences to each party
- Contributions by one spouse to the education, training, or earning power of the other
- Financial condition in which each party will be left after the divorce
A commonly referenced guideline in Hawaii suggests one year of alimony for every three years of marriage, though this is not a statutory formula. For example, a 15-year marriage might result in approximately 5 years of spousal support, while a 30-year marriage could warrant 10 years of maintenance.
Adultery and Property Division: The Dissipation Exception
While adultery itself does not affect how Hawaii courts divide marital property, economic misconduct related to an affair can impact the property division outcome. Hawaii follows equitable distribution principles under HRS § 580-47, meaning courts divide marital property fairly (though not necessarily equally) based on relevant circumstances.
The key exception involves dissipation of marital assets. If a cheating spouse spent significant marital funds on an affair, including gifts to a paramour, hotel expenses, travel costs, or other extramarital expenditures, the court may charge those dissipated funds against the offending spouse during property division. This principle was established in Hawaii case law (135 H. 340, 350 P.3d 1008 (2015)), which held that dissipation of marital assets after the commencement of divorce proceedings was chargeable to the spending spouse as marital waste.
| Factor | Adultery Impact |
|---|---|
| Grounds for Divorce | None — Hawaii is no-fault |
| Alimony Amount | None — fault explicitly excluded |
| Property Division | None — unless assets dissipated |
| Dissipation of Assets | Yes — wasteful spending charged to offending spouse |
| Child Custody | None — unless affair partner poses risk to child |
| Child Support | None — calculated by Hawaii Guidelines formula |
To prove dissipation of marital assets related to adultery, the spouse alleging waste must demonstrate:
- Marital funds were used for non-marital purposes (such as gifts to an affair partner)
- The expenditures occurred during the marriage or after the divorce was filed
- The spending was done without the knowledge or consent of the other spouse
- The amounts were significant enough to warrant judicial consideration
If dissipation is proven, the court may award the innocent spouse a larger percentage of the remaining marital estate to compensate for the wasted funds. Courts have discretion to take punitive or restorative action by adjusting the property division to account for the economic misconduct.
Adultery and Child Custody in Hawaii
Adultery does not directly affect child custody determinations in Hawaii. Under HRS § 571-46, Hawaii courts must award custody based on the best interests of the child, and marital infidelity is not listed among the statutory factors for this determination.
The best interest factors under HRS § 571-46 include:
- History of caregiving and parenting by each parent
- Physical, emotional, safety, and educational needs of the child
- Need for the child to maintain relationships with siblings
- Evidence of past or current substance abuse by either parent
- History of family violence or domestic abuse
- Each parent's ability to separate their own needs from the child's needs
- Any history of sexually or physically abusing any child
- Any history of neglect or emotional abuse of any child
An affair could theoretically affect custody only if it directly impacted the children's wellbeing. For example, if a parent exposed children to inappropriate situations, neglected parenting duties due to the affair, or if the affair partner posed a risk to the children's safety, these circumstances (not the adultery itself) could influence custody decisions.
The court may hear testimony from any expert whose knowledge or experience is relevant to determining the child's best physical, mental, moral, and spiritual wellbeing. Any custody award remains subject to modification whenever the best interests of the child require or justify changes.
Filing for Divorce in Hawaii: Requirements and Process
To file for divorce in Hawaii, you must meet the domicile requirement established by HRS § 580-1. Following amendments enacted by Act 69 of 2021, you must be domiciled in Hawaii at the time you file for divorce. Domicile means living in Hawaii with the intention to remain as your permanent home. There is no longer a specific minimum time period required for filing, though some circuits may require domicile for a continuous period of six months before the final decree can be entered.
Hawaii's divorce process timeline:
| Stage | Uncontested | Contested |
|---|---|---|
| Filing to Service | 1-2 weeks | 1-2 weeks |
| Response Period | 20 days | 20 days |
| Discovery/Negotiation | N/A | 3-12 months |
| Mediation (if required) | N/A | 4-8 weeks |
| Trial (if needed) | N/A | 1-6 months wait |
| Final Decree | 4-8 weeks | 6-24 months |
Unlike many other states, Hawaii does not impose a mandatory waiting period between filing for divorce and the court's ability to grant the final decree. Uncontested divorces in Hawaii typically finalize in 6 to 10 weeks from filing, while contested divorces may take 6 to 24 months depending on case complexity and court availability.
The filing fee for divorce in Hawaii is $215 for couples without minor children or $265 for couples with minor children. The $265 fee includes a $50 surcharge for the mandatory Kids First parent education program required under HRS § 571-46. Additional costs include $40-$75 for service of process and $215 per additional motion filed during the proceedings.
How to Prove Adultery Occurred (Even Though It Doesn't Affect the Divorce)
While proof of adultery will not affect your divorce outcome in Hawaii, you may still need to document infidelity to establish dissipation of marital assets or for personal closure. Common forms of evidence include:
- Bank and credit card statements showing unusual expenditures
- Hotel receipts, travel records, and restaurant charges
- Text messages, emails, and social media communications
- Photographs or video evidence
- Testimony from witnesses who observed the affair
- Gifts purchased for an affair partner using marital funds
- Phone records showing frequent contact with a specific number
If you are seeking to prove dissipation of assets related to an affair, focus documentation on the financial impact rather than the moral aspects of the infidelity. Courts are concerned with economic misconduct, not moral judgments about marital behavior.
Strategic Considerations for Divorce Involving Adultery
Even in Hawaii's no-fault system, discovering a spouse's affair affects how you should approach divorce proceedings:
-
Document financial misconduct immediately: If you suspect your spouse spent marital funds on an affair, gather bank statements, credit card records, and receipts before filing. Hawaii courts can charge dissipated assets against the offending spouse.
-
Secure separate finances: Open individual accounts and monitor joint accounts for unusual activity. Hawaii courts can issue temporary restraining orders to prevent further dissipation of marital assets.
-
Focus negotiations on tangible factors: Since fault cannot affect alimony or property division (except for dissipation), concentrate on objective factors like earning capacity, standard of living, and duration of marriage.
-
Protect children from conflict: Hawaii courts prioritize children's wellbeing. Exposing children to parental conflict about infidelity could reflect poorly on your parenting judgment.
-
Consider counseling: Individual therapy can help process emotional trauma while maintaining focus on practical divorce outcomes.
Timeline Comparison: Adultery Divorce vs. Standard Divorce in Hawaii
Because Hawaii does not recognize fault-based divorce, there is no difference in timeline between divorces involving adultery and those without infidelity allegations. All Hawaii divorces proceed under the same no-fault framework.
| Divorce Type | Filing Fee | Timeline | Adultery Impact |
|---|---|---|---|
| Uncontested (no children) | $215 | 6-10 weeks | None |
| Uncontested (with children) | $265 | 6-10 weeks | None |
| Contested (no children) | $215 + motions | 6-18 months | None unless dissipation |
| Contested (with children) | $265 + motions | 12-24 months | None unless dissipation |
Cases filed in the 1st Circuit (Oahu) may take slightly longer due to higher volume, as Oahu handles approximately 65% of all Hawaii divorce filings. Neighbor island circuits (2nd through 5th) typically process cases more quickly due to lower caseloads.
Alternatives to Divorce for Couples Dealing with Infidelity
Hawaii law provides alternatives to divorce that some couples choose when addressing infidelity:
Legal Separation: Under HRS § 580-71, Hawaii courts can grant legal separation rather than divorce. This maintains the marriage legally while resolving issues of property, support, and custody. Some couples choose this option for religious reasons or to maintain health insurance benefits.
Separate Maintenance: A separate maintenance action allows spouses to live apart with court-ordered financial arrangements without dissolving the marriage.
Reconciliation: Hawaii courts encourage reconciliation where possible. Under HRS § 580-42, if both parties reconcile before the divorce is finalized, they may dismiss the action.
Fee Waivers and Affordable Divorce Options
If you cannot afford the $215-$265 filing fee, Hawaii provides fee waivers for qualifying individuals. If your income falls below 125% of the federal poverty guidelines, you can file Form 1-P (Application for Order to Proceed Without Prepayment of Fees and/or Costs) to request a waiver of court costs.
For 2026, 125% of the federal poverty guideline for a single person in Hawaii is approximately $19,688 annually. The threshold increases for larger households.
Self-represented (pro se) uncontested divorce is possible in Hawaii for as little as $265-$400 total, including filing fees and service of process costs. The Hawaii State Judiciary provides self-help forms and resources for individuals proceeding without attorneys.
Frequently Asked Questions About Adultery and Divorce in Hawaii
Can I use my spouse's affair as grounds for divorce in Hawaii?
No, Hawaii does not recognize adultery as grounds for divorce. Under HRS § 580-41, the only recognized ground is irretrievable breakdown of the marriage. You cannot file a fault-based divorce citing your spouse's infidelity. The filing fee remains $215-$265 regardless of the circumstances surrounding your divorce.
Will my cheating spouse receive less alimony because of the affair?
No, adultery has no impact on spousal support determinations in Hawaii. Under HRS § 580-47, Hawaii courts are explicitly prohibited from considering marital fault when awarding maintenance. A spouse who committed adultery will receive the same alimony calculation as any other spouse based solely on the 13 statutory financial factors.
Can I get a larger share of property because my spouse cheated?
Not because of the adultery itself, but potentially because of dissipation of assets. If your spouse spent significant marital funds on the affair, including gifts, travel, hotels, or other expenses related to the extramarital relationship, Hawaii courts can charge those wasted funds against your spouse during property division under HRS § 580-47.
Does adultery affect child custody decisions in Hawaii?
No, adultery does not directly affect custody in Hawaii. Under HRS § 571-46, courts determine custody based solely on the child's best interests. An affair could only impact custody if it directly affected the child's wellbeing, such as exposing children to inappropriate situations or if the affair partner posed a safety risk.
How quickly can I get divorced if my spouse committed adultery?
The timeline is identical to any other divorce in Hawaii. Uncontested divorces typically finalize in 6-10 weeks, while contested divorces take 6-24 months. Hawaii has no mandatory waiting period, and adultery allegations do not accelerate or delay the process.
Should I hire a private investigator to prove my spouse's affair?
Generally unnecessary for divorce purposes in Hawaii since adultery cannot be used as grounds or to affect alimony/property division. However, a private investigator may be helpful if you need to document financial dissipation, such as proving your spouse spent marital funds on an affair partner or locating hidden assets.
Can my spouse's affair partner be sued in Hawaii?
No, Hawaii does not recognize alienation of affection or criminal conversation claims. These common law torts, which allowed a spouse to sue their partner's paramour, have been abolished in Hawaii. You have no legal recourse against the person with whom your spouse had an affair.
What if my spouse's affair resulted in an STI or pregnancy?
These complications do not change the legal analysis for divorce in Hawaii. However, medical expenses related to STI treatment could potentially be considered in property division as a form of economic damage. A child born from an affair raises separate paternity and child support issues that may complicate the divorce proceedings.
How do I protect my assets if I discover my spouse is having an affair?
Document all marital assets and debts immediately. Gather copies of bank statements, investment accounts, property records, and tax returns. Hawaii courts can issue temporary restraining orders preventing dissipation of marital assets once divorce is filed. Consider consulting with a divorce attorney before confronting your spouse to ensure proper asset protection strategies are in place.
Is there a waiting period after discovering adultery before I can file for divorce?
No, Hawaii has no waiting period requirements. You can file for divorce immediately after discovering your spouse's affair, or at any time you decide the marriage is irretrievably broken. The only requirement is that you be domiciled in Hawaii at the time of filing under HRS § 580-1.
