Factors That Affect Child Support in South Dakota
Technical details and legal basis
South Dakota uses the Income Shares model (SD Guidelines (SDCL 25-7-6.2)) 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 South Dakota
- • South Dakota uses the Income Shares model, combining both parents' net incomes to determine the total child support obligation.
- • Each parent's share is proportional to their percentage of the combined net income.
- • The schedule covers combined net monthly incomes up to $12,000. For incomes above this amount, the court uses discretion.
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.
