In Indiana, child support does not depend on marriage — it depends on being a child’s legal parent. After the court establishes parentage, it calculates child support using the Indiana Child Support Guidelines, which aim to meet the child’s financial needs based on each parent’s circumstances. It is important to familiarize yourself with how the state decides legal parentage and what this means for child support.
How do courts establish parentage?
If you are not married, you and your partner can sign a paternity affidavit. This way, you can determine the child’s legal father. However, if you do not sign the affidavit, or if someone challenges paternity, either parent or the state can ask the court to make a decision after examining their case and circumstances. The court may also order DNA testing before officially naming the legal father of a child.
After establishing paternity, the court may order a parent to pay child support. Indiana requires support orders to follow the Indiana Child Support Guidelines and considers factors such as:
- Each parent’s income
- Parenting time
- Health insurance costs
- Daycare
Courts also consider other factors and expenses, such as those listed under Indiana Code Section 31-16-6-1. Bear in mind that when it comes to child support, you should not rely on informal agreements. Only a court order controls enforceable child support in Indiana.
Child support does not depend on your marital status
If you are not married in Indiana, you may still have to pay child support once the law establishes you as a parent. After that point, the court applies Indiana’s child support framework and issues an enforceable order. Many parents who are unsure of their rights seek guidance from a legal professional, who can help them navigate complex family laws and decide what to do next.
