How Child Support Is Calculated in Oklahoma
Factors That Affect Child Support in Oklahoma
Technical details and legal basis
Oklahoma uses the Income Shares model (Oklahoma Child Support Guidelines (43 O.S. § 118)) 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 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).
- • The court may deviate from guidelines based on the child's special needs, extraordinary medical expenses, or other factors that make strict application of the guidelines unjust.
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.
