Child Support in Indiana
Indiana uses the Indiana Child Support Rules and Guidelines, an income shares model, to calculate child support. The calculation starts with each parent's weekly gross income. It adjusts for children from prior relationships and other support obligations. From there, it computes a basic child support obligation and divides it between the parents. The guidelines took effect in 1989. Indiana courts update them periodically. Indiana's circuit and superior courts hear child support cases. Services are delivered at the county level. Each county's elected prosecutor operates under a cooperative agreement with the state Child Support Bureau, part of the Department of Child Services. Together they provide IV-D child support services to families.

The income shares guidelines
The Indiana Child Support Rules and Guidelines define weekly gross income for each parent. They cover self-employment income and in-kind payments. They also address cases where a parent is unemployed or underemployed. From there, the guidelines compute each parent's weekly adjusted income. This factors in support already owed for other children. Then they calculate the basic child support obligation. Additions cover work-related child care, health insurance, and extraordinary health or education expenses. The obligation is divided between the parents based on their share of the combined income.
Applying for services through your county prosecutor
Indiana delivers child support services through a partnership. The state Child Support Bureau, part of the Department of Child Services, works with the elected prosecutor's office in each county. Signing up for services is free. A parent applies through the state's child support enrollment page. The program can help establish paternity and set up a new order. It can also enforce an order that already exists.
Who hears an Indiana child support case
Indiana's circuit and superior courts handle general civil and family matters at the county level. They decide child support as part of a dissolution of marriage, a paternity action, or a standalone petition. The court applies the Indiana Child Support Rules and Guidelines to the parents' verified weekly income to calculate the presumptive obligation. It can deviate from the guideline amount under Support Rule 3 when the calculated amount would be unjust.
Modifying an existing order
An Indiana child support order can be modified when there's a substantial change in circumstances that makes the existing terms unreasonable. Confirm the current statutory rule with the county prosecutor's child support office or the Indiana courts before filing. Indiana also allows modification without proving changed circumstances once an order has been in place long enough that reapplying the guidelines would produce a significantly different amount.
Enforcement tools
Indiana's child support program, delivered through county prosecutors and the state Child Support Bureau, uses several enforcement tools not available outside the official program. These include income withholding directly from a paying parent's wages and interception of state and federal tax refunds. A parent who does not comply with a court support order can be brought before the court and held in contempt. License suspension is available as a remedy for parents who are significantly behind.
