Frequently Asked Questions
Child support is typically calculated using state guidelines that consider: both parents' gross incomes, number of children, custody arrangement (overnights with each parent), health insurance costs, childcare expenses, and other allowed deductions. Most states use either the Income Shares Model or Percentage of Income Model.
Included income generally encompasses: wages, salaries, commissions, bonuses, self-employment income, rental income, investment income, unemployment benefits, and certain disability payments. Some states may also consider overtime, while others exclude it if not consistent.
Yes, child support can be modified if there's a significant change in circumstances, such as: income changes of 15-20% or more, job loss, medical emergencies, changes in custody arrangements, or changes in the child's needs. Either parent can request a review through the court or child support agency.
Consequences for non-payment may include: wage garnishment, tax refund interception, license suspension (driver's, professional, recreational), property liens, credit reporting, passport denial, and even contempt of court charges leading to fines or jail time. Enforcement options vary by state.
Standard child support typically covers basic needs: food, shelter, clothing, and basic medical care. Extracurricular activities, private school, and college expenses may be addressed separately in the parenting plan or court order. Some states require divorced parents to contribute to college costs; others do not.
