North Carolina law uses the “Income Share” model for determining child support orders. Basically, both parents’ incomes are totaled together, and the court determines the cost of raising the child based on that total.
Then, the non-custodial parent is ordered to pay a percentage of that cost based on their proportional share of the parent’s combined income.
The judge will also consider how many overnights each parent has per year with the child when determining what child support payments will be.
