Child Custody

Child Support

Child support follows state guideline formulas, not a judge's mood. Understanding the inputs—both incomes, overnights, health insurance, childcare—lets you check the math and request corrections.

Key takeaways

  • All states use a guideline formula; most account for parenting time.
  • Support and parenting time are legally separate—never withhold one over the other.
  • Report income honestly; imputed income applies when courts believe you are underemployed.
  • Modification usually requires a substantial change (job loss, schedule change).

Legal / educational information

What goes into the formula

Gross incomes of both parents, number of children, overnights with each parent, health-insurance premiums for the child, and work-related childcare. Some states add extraordinary medical and school costs.

Legal / educational information

If you lose your job

File for modification immediately. Arrears generally cannot be reduced retroactively before your filing date.

Frequently asked questions

Not automatically. Most formulas reduce support with more overnights, but a higher-earning parent may still pay.
