Factors That Affect Child Support in Oklahoma
Important Notes for Oklahoma
- Oklahoma uses the Income Shares model, combining both parents' gross incomes to determine the total child support obligation.
- Each parent's share of the obligation is proportional to their percentage of the combined gross income.
- Oklahoma applies a shared parenting adjustment when the non-custodial parent exercises overnight visitation for more than 110 overnights per year (approximately 30% of the time).

Example Child Support Calculation in Oklahoma
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined monthly income: $5,000 + $3,000 = $8,000
Step 2: Parent A's income share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation from the guidelines schedule for $8,000 combined income and 2 children.
Step 4: Multiply the basic obligation by Parent A's share (62.5%) to determine their payment.
Note: Additional adjustments for health insurance, child care, and parenting time may apply.
