Indiana child support guidelines create a presumptive amount — the default amount courts should order. However, courts have discretion to deviate from the guideline amount when circumstances warrant. The guideline amount is a starting point, not an absolute.
Use the Indiana child support calculator to know the guideline amount before any discussion of deviation.
What Deviation Means
A deviation is a court-ordered child support amount that differs from the calculated guideline amount. It can be:
- Upward deviation: More than the guideline amount
- Downward deviation: Less than the guideline amount
Deviation requires the court to make specific findings explaining why the deviation serves the best interests of the child. Courts cannot deviate arbitrarily — the reasons must be documented in the order.
Grounds for Downward Deviation
1. Parents Reach a Voluntary Agreement
The most common deviation scenario: both parents agree to a different support amount and submit it to the court. However:
- Courts are not required to approve agreed deviations — they must independently find the agreed amount serves the child’s best interests
- Even if both parents agree to $0 support, the court must make findings supporting that amount
- The 2024 guideline update added a requirement that worksheets be filed even when parents agree to $0 support
What courts look for in agreed deviations:
- Both parents understand the guideline amount
- The child’s needs are being met by alternative arrangements (e.g., CP receives a larger share of other assets in settlement)
- No coercion in the agreement
2. High-Income Cases
When combined weekly income exceeds the top of the BSO schedule (currently around $2,500–$3,000/week combined), courts have discretion because the schedule does not extrapolate indefinitely. Courts may:
- Apply the guideline percentage to income above the schedule top
- Cap support at an amount that meets the child’s reasonable needs without excessive enrichment
- Adjust based on the child’s demonstrated needs and lifestyle
3. NCP Provides Substantial In-Kind Support
If the NCP provides housing, health insurance, clothing, or other direct benefits that the guideline amount would also cover, courts may reduce the cash support obligation to avoid double-counting.
4. Financial Hardship
When the guideline amount would leave the NCP below a subsistence income level, courts may reduce the obligation. Indiana’s guidelines include a low-income floor — below certain income levels, courts determine support case-by-case.
Relevant factors:
- NCP’s actual monthly expenses (housing, necessary food, transportation to work)
- Whether the NCP supports other dependents
- Whether the hardship is temporary or ongoing
5. Special Needs or Extraordinary Expenses
Conversely, this can support upward deviation when the child has:
- Significant medical needs not covered by insurance
- Educational needs requiring special programs or therapy
- Extraordinary activities or programs both parents contributed to during the marriage
Grounds for Upward Deviation
| Situation | How courts handle |
|---|---|
| Child’s special medical needs | Add specific medical cost-sharing above guideline |
| Child’s educational needs | Add private school or tutoring costs if historically provided |
| NCP has significant undisclosed assets | Court may attribute investment income from assets |
| Lifestyle discrepancy (NCP lives lavishly vs reported income) | Imputation of income + possible upward deviation |
How Deviation Works Procedurally
Step 1: Calculate the guideline amount using the standard formula. This must appear in all child support orders per the 2024 guideline update.
Step 2: Either party (or both jointly) requests deviation. The requesting party provides evidence supporting the deviation.
Step 3: The court makes written findings specifying:
- The guideline amount
- The deviation amount
- The specific reasons why deviation serves the child’s best interests
Without written findings, the order is subject to reversal on appeal.
What Courts Will Not Do
- Reduce support below $0 (negative child support is not permitted)
- Approve an agreed deviation without independent analysis of the child’s best interests
- Grant permanent deviation based on temporary circumstances without a review mechanism
- Deviate based solely on the NCP’s preference to pay less
Deviation vs Modification
Deviation is set at the time the order is established — it’s an agreement or finding that the guideline amount is inappropriate from the start.
Modification changes an existing order when circumstances change substantially after the order is in place. See when and how to modify Indiana child support for the modification process.
For an accurate starting point before any deviation discussion, run your numbers in the Indiana child support calculator and review what counts as income for Indiana child support.
