11. State-Specific Notes

1. Income Shares Model: Indiana uses the Income Shares Model, which estimates what both parents would spend on children in an intact household, then divides that amount proportionally based on each parent's income.

2. Weekly Calculation: Indiana calculates child support on a weekly basis, unlike most states that use monthly figures.

3. Emancipation at 19: Indiana's age of emancipation is 19, which is older than many states. The court may also order educational support beyond age 19.

4. 2024 Guidelines: The current guidelines became effective January 1, 2024, after being adopted by the Indiana Supreme Court in late 2023.

5. Parenting Time Credit: A credit is available to the non-custodial parent based on the number of overnights exercised, reducing the support obligation to account for direct expenditures during parenting time.

6. In-Kind Benefits: Employer-provided benefits such as housing, vehicles, and meals are included in gross income at fair market value.
