Indiana law draws a sharp distinction between spousal maintenance (alimony) and child support, yet many divorcing couples confuse the two obligations. Under IC 31-15-7-2, Indiana courts may award spousal maintenance in only three narrow circumstances, making it one of the most restrictive states in the nation for alimony. Child support, by contrast, follows mandatory guidelines under IC 31-16-6-1 and continues until each child reaches age 19. Understanding the difference between alimony and child support in Indiana determines how much you pay or receive, how long payments last, and what tax treatment applies to each obligation.

What Is Spousal Maintenance (Alimony) in Indiana?
Indiana courts may award spousal maintenance only when a requesting spouse meets one of three statutory conditions under IC 31-15-7-2: physical or mental incapacity preventing self-support, caregiving duties for an incapacitated child, or the need for rehabilitative support not exceeding 36 months. Unlike most states, Indiana does not permit judges to award long-term alimony based on marital lifestyle, length of marriage, or income disparity alone. This makes spousal support vs child support in Indiana fundamentally different from neighboring states like Illinois or Ohio.
Indiana uses the term "spousal maintenance" rather than alimony in all statutes and court orders. The three qualifying circumstances create strict eligibility gates that exclude many requesting spouses who would receive alimony in other jurisdictions. Marital misconduct, including infidelity or abandonment, has no bearing on maintenance awards because Indiana is a pure no-fault divorce state.
Incapacity-Based Maintenance
Incapacity maintenance applies when a spouse has a physical or mental condition that materially affects their ability to support themselves. Courts require medical documentation establishing the disability and its impact on employability. Payments continue for the duration of the incapacity, with no statutory time limit, though the paying spouse may petition to modify or terminate if circumstances change.
Caregiver Maintenance
Caregiver maintenance supports a spouse who must forgo employment to care for a child with physical or mental incapacity. Eligibility requires the custodial parent to demonstrate that the child's condition necessitates full-time care preventing regular employment. Payments terminate when the caregiving situation ends or when the child turns 18, whichever occurs first.
Rehabilitative Maintenance
Rehabilititative maintenance provides temporary support while a spouse obtains education or training necessary for employment. Under IC 31-15-7-2(3), rehabilitative maintenance cannot exceed 36 months from the date of the final decree. Courts consider four factors: educational level at marriage and divorce, career interruptions due to homemaking or childcare, earning capacity and skills, and the time and expense required to become employable.
What Is Child Support in Indiana?
Indiana calculates child support using the Income Shares Model, which estimates what parents would have spent on children if the family remained intact and divides that obligation proportionally based on each parent's gross weekly income. Under IC 31-16-6-1, courts consider the financial resources of both parents, the child's standard of living before divorce, the child's physical and educational needs, and each parent's ability to pay. Child support continues until each child turns 19 under Indiana law, not 18 as in many other states.
The Indiana Supreme Court publishes official Child Support Guidelines with lookup tables showing the basic weekly support obligation based on combined parental income and number of children. For example, parents with a combined weekly adjusted income of $1,800 and two children would reference a basic support amount of $368 per week, or approximately $1,472 per month. The non-custodial parent's share depends on their percentage of combined income.
Income Shares Calculation Steps
Indiana's child support calculation follows seven steps documented in the official Child Support Obligation Worksheet. First, determine each parent's gross weekly income. Second, apply statutory adjustments for preexisting support orders and certain allowable deductions. Third, add both parents' adjusted incomes together. Fourth, calculate each parent's percentage share of combined income. Fifth, reference the Guideline Schedule for the basic weekly support amount. Sixth, add work-related childcare costs and health insurance premiums for the children. Seventh, prorate the total obligation between parents based on income percentages.
Parenting Time Credit
Indiana provides a parenting time credit that reduces the non-custodial parent's child support obligation based on overnight visitation. The credit increases in blocks as overnights rise because the parent exercising parenting time incurs direct costs for meals, transportation, and daily needs during those periods. The 2024 guideline revisions clarified calculation methods for families with varying overnight schedules across multiple children.
Healthcare Expense Allocation
The 2024 Indiana Child Support Guidelines eliminated the former "6% Rule" that held custodial parents responsible for the first 6% of uninsured medical costs. Under current rules, both parents share all uninsured healthcare expenses in proportion to their respective incomes. This change can significantly affect total support obligations for families with children requiring ongoing medical care.
Alimony vs Child Support Indiana: Side-by-Side Comparison
Understanding which is more between alimony or child support depends on your specific circumstances, but the differences in Indiana are substantial. This comparison table highlights the fundamental distinctions between spousal maintenance and child support obligations.
| Factor | Spousal Maintenance | Child Support |
|---|---|---|
| Statutory Authority | IC 31-15-7-2 | IC 31-16-6-1 |
| Calculation Method | Judicial discretion, no formula | Income Shares Model with published guidelines |
| Eligibility | 3 narrow circumstances only | All children of the marriage |
| Duration | 36 months max for rehabilitative; unlimited for incapacity | Until child turns 19 |
| Termination Events | Remarriage, cohabitation, or recovery from incapacity | Child emancipation, death, or military service |
| Tax Treatment | Not deductible/not taxable (post-2018) | Not deductible/not taxable |
| Modifiability | Yes, upon material change | Yes, if 20% deviation or changed circumstances |
| Enforcement | Contempt of court | Wage withholding, license suspension, tax intercept |
How Indiana Courts Decide Spousal Maintenance Amounts
Indiana has no statutory formula for calculating spousal maintenance amounts, leaving the determination entirely to judicial discretion within the three qualifying categories. Courts analyze the requesting spouse's reasonable financial needs and the paying spouse's ability to meet those needs after satisfying their own obligations. Judges examine income, assets, debts, living expenses, and the standard of living during the marriage when setting maintenance amounts.
Some Indiana family law practitioners reference an informal guideline of one year of maintenance per three years of marriage, but this ratio appears nowhere in Indiana statute or appellate decisions. Courts are not bound by any such formula, and each case receives individual analysis based on the specific facts presented. The absence of clear guidelines creates uncertainty for both requesting and paying spouses during negotiations.
Settlement Agreements Can Exceed Statutory Limits
Parties who negotiate a settlement agreement may include maintenance terms that exceed the 36-month rehabilitative cap. A written agreement between spouses can provide for maintenance of any duration, any amount, and any termination conditions the parties choose. Settlement agreements represent the only path to extended maintenance when no incapacity or caregiver situation exists under Indiana law.
How Indiana Courts Calculate Child Support
Indiana courts calculate child support using the official Child Support Guidelines published by the Indiana Supreme Court, accessible through the free online calculator at in.gov/courts/services/child-support-calculator. The calculation produces court-ready worksheets accepted by all 92 Indiana county courts. Parents typically complete the calculator in 15 to 20 minutes if they have income documentation, insurance costs, and parenting time schedules available.
The Income Shares Model uses gross income rather than net income to reduce discovery disputes over claimed deductions. Gross income includes wages, salaries, bonuses, commissions, self-employment income, rental income, dividends, interest, trust income, Social Security benefits, workers' compensation, unemployment benefits, and imputed income for voluntarily unemployed or underemployed parents.
Example Calculation
Consider parents with the following circumstances: Father earns $5,200 monthly ($1,200 weekly), Mother earns $3,467 monthly ($800 weekly), and they share two children with Father having standard parenting time of 96 overnights annually. Their combined weekly adjusted income of $2,000 produces a basic child support obligation of approximately $408 per week. Father's income represents 60% of the combined total, making his proportional share $245 per week before parenting time credits. After applying overnight credits, his final obligation might reduce to approximately $220 per week, or $880 per month.
When Child Support and Spousal Maintenance Interact
Indiana courts consider existing child support obligations when analyzing a spouse's ability to pay maintenance. Child support takes priority because it addresses children's basic needs, while maintenance addresses a spouse's transitional or disability-related needs. Courts calculate child support first using the mandatory guidelines, then determine whether the paying spouse has sufficient remaining income to pay maintenance.
When both obligations exist, the paying spouse may face significant financial strain if combined payments exceed reasonable limits. Indiana courts must balance the requesting spouse's maintenance needs against the paying spouse's ability to meet their own basic living expenses after satisfying child support. This interaction often results in lower maintenance awards when substantial child support obligations already exist.
Modification of Support Orders in Indiana
Indiana permits modification of both spousal maintenance and child support when material changes in circumstances occur. For child support, IC 31-16-8-1 provides two distinct pathways: demonstrating substantial and continuing changed circumstances that make the existing order unreasonable, or showing the current order differs by more than 20% from what guidelines would produce after at least 12 months have passed since the order was issued or last modified.
Common qualifying changes for modification include job loss, significant income changes, changes in the child's medical needs, changes in parenting time schedules, and new support obligations for other children. For spousal maintenance, modification typically requires showing that the original circumstances have materially changed, such as the recipient spouse becoming self-supporting or the paying spouse experiencing involuntary income reduction.
Automatic Termination Events
Spousal maintenance automatically terminates upon the death of either party or the remarriage of the recipient spouse under Indiana law. Some courts also terminate maintenance when the recipient begins cohabitating in a marriage-like relationship, though this requires court action rather than automatic termination. Child support terminates automatically when the child turns 19, though obligations may continue longer for children with special needs or may extend to cover college expenses under IC 31-16-6-2.
Tax Treatment of Support Payments
For Indiana divorce agreements finalized after December 31, 2018, neither spousal maintenance nor child support payments affect federal income taxes. The paying spouse cannot deduct maintenance payments, and the recipient spouse does not report them as taxable income. This change resulted from the federal Tax Cuts and Jobs Act of 2017, and Indiana conforms to federal tax treatment.
This uniform tax treatment eliminates the historical distinction where alimony was tax-deductible while child support was not. For divorces finalized before 2019, the old tax rules continue to apply unless the parties modify their agreement and explicitly elect the new treatment. Tax planning now focuses on property division and filing status rather than support payment structure.
Enforcement Mechanisms for Support Obligations
Indiana provides robust enforcement tools for child support, including mandatory income withholding through the Indiana State Central Collection Unit (INSCCU), driver's license suspension, professional license suspension, tax refund interception, passport denial for arrearages exceeding $2,500, and contempt of court proceedings with potential jail time. The state charges a $55 Annual Support Enforcement Fee (ASFE) per case and applies 1.5% monthly interest on past-due amounts.
Spousal maintenance enforcement relies primarily on contempt of court proceedings. Unlike child support, maintenance payments do not automatically route through INSCCU, and wage withholding requires a separate court order. Enforcement tends to be more cumbersome for maintenance, making inclusion of automatic wage withholding language in settlement agreements advisable.
Filing for Divorce in Indiana: Costs and Timeline
Indiana divorce filing fees range from $157 to $185 depending on the county, with Marion County (Indianapolis) charging $177. As of April 2026, verify current fees with your local clerk's office as amounts may change. Additional costs include service of process ($28 through Sheriff's Office or $40–$75 through private process server), certified copy fees ($30–$50), and potential mediation costs.
Indiana imposes a mandatory 60-day waiting period under IC 31-15-2-10 before any divorce can be finalized. This waiting period runs from the date of filing, not from service on the other spouse. Even in completely uncontested cases where both parties agree on all issues, the earliest possible final decree date is 61 days after filing. Contested divorces involving disputes over property, custody, or support typically take 6 to 18 months to resolve.
Residency Requirements
To file for divorce in Indiana, at least one spouse must have resided in Indiana for six months and in the filing county for three months under IC 31-15-2-6. These requirements must be satisfied before filing; the 60-day waiting period runs after filing. Unlike some states, Indiana does not require spouses to live separately before filing for divorce.
Frequently Asked Questions
What is the difference between alimony and child support in Indiana?
Spousal maintenance (alimony) in Indiana compensates a spouse who cannot support themselves due to incapacity, caregiver duties, or need for rehabilitative training, with a maximum duration of 36 months for rehabilitative support under IC 31-15-7-2. Child support ensures both parents contribute to children's living expenses proportionally based on income until age 19 under IC 31-16-6-1. Child support follows mandatory guidelines while maintenance amounts are discretionary.
Which is typically more in Indiana: alimony or child support?
Child support typically produces higher monthly payments than spousal maintenance in Indiana because child support follows mandatory guidelines based on income while maintenance awards are discretionary and limited to narrow circumstances. For example, a parent earning $5,200 monthly might pay $880 monthly in child support, while maintenance awards rarely exceed $1,000–$1,500 monthly when granted at all. Indiana's restrictive maintenance statute means most divorcing spouses receive no alimony.
How long does spousal maintenance last in Indiana?
Rehabilititative maintenance in Indiana cannot exceed 36 months (3 years) from the final divorce decree under IC 31-15-7-2(3). Incapacity-based maintenance has no statutory limit and continues for the duration of the physical or mental disability. Caregiver maintenance ends when caregiving is no longer required or when the child turns 18. Settlement agreements may provide for longer periods if both parties consent.
At what age does child support end in Indiana?
Child support in Indiana ends when each child turns 19 years old under IC 31-16-6-6, not 18 as in most other states. Courts may extend support beyond age 19 for children with physical or mental disabilities or may order college contribution under IC 31-16-6-2. Child support also terminates upon the child's marriage, military enlistment, or emancipation by court order.
Can I receive both spousal maintenance and child support in Indiana?
Yes, a spouse may receive both spousal maintenance and child support simultaneously if they qualify for maintenance under one of the three statutory categories and are the custodial parent. However, courts calculate child support first using mandatory guidelines, then assess whether the paying spouse has sufficient remaining income for maintenance. Combined obligations often result in reduced maintenance when substantial child support already exists.
How is child support calculated in Indiana?
Indiana calculates child support using the Income Shares Model, which combines both parents' gross weekly incomes, references guideline tables for the basic support obligation based on number of children, adds childcare and health insurance costs, then divides the total proportionally between parents based on income percentages. The Indiana Judicial Branch provides a free calculator at in.gov/courts that generates court-ready worksheets for all 92 counties.
Can spousal maintenance be modified in Indiana?
Yes, Indiana courts may modify spousal maintenance upon showing material changes in circumstances, such as the recipient becoming self-supporting, the paying spouse experiencing involuntary income reduction, or the recipient remarrying or cohabitating. However, courts cannot extend rehabilitative maintenance beyond the 36-month statutory cap. Only settlement agreements can provide for extended maintenance periods.
Does marital misconduct affect support awards in Indiana?
No, Indiana is a pure no-fault divorce state, and marital misconduct including infidelity, abandonment, or abuse cannot be considered when awarding spousal maintenance or calculating child support under IC 31-15-7-2. Courts may only consider the statutory factors related to financial circumstances, employability, and children's needs when setting support obligations.
What happens if my ex stops paying child support?
Indiana enforces child support through the Indiana State Central Collection Unit (INSCCU) using mandatory income withholding, tax refund interception, license suspension (driver's and professional), passport denial for arrearages over $2,500, contempt proceedings with potential jail time, and 1.5% monthly interest on past-due amounts. Report non-payment to the INSCCU or file a motion for contempt with the court that issued the support order.
Can parents agree to no child support in Indiana?
Indiana courts must approve all child support arrangements and may reject agreements that provide inadequate support for children. While parents have flexibility in crafting custody and parenting time arrangements, child support must meet or exceed guideline amounts unless deviation is justified by specific circumstances documented on the worksheet. Courts prioritize children's financial needs over parental preferences.
