Factors That Affect Child Support in Kansas
Technical details and legal basis
Kansas uses the Income Shares model (KS Admin Regs 29-5-300) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.
Important Notes for Kansas
- • Kansas uses the Income Shares model, combining both parents' gross incomes to determine the total child support obligation.
- • The Kansas guidelines convert gross income to a "domestic gross income" figure that accounts for maintenance paid or received and other adjustments.
- • Kansas provides a detailed worksheet (Child Support Worksheet) that accounts for parenting time, child care, health insurance, and other factors.
- • The court may deviate from guidelines based on the overall financial condition of the parties and the best interests of the child.
Example Calculation
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined income: $8,000
Step 2: Parent A's share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation for $8,000 combined and 2 children.
Step 4: Multiply by Parent A's share (62.5%).
Adjustments for health insurance, child care, and parenting time may apply.
