What is the effect of an increase in an obligor's income on child support payments?

When an obligor's income increases, the correct interpretation is that the child is entitled to a share of that increase in the form of higher child support payments. This principle is rooted in the idea that child support should reflect the financial ability of the parent to contribute to the child's welfare, which naturally grows with an increase in income. Courts often reevaluate child support obligations when a material change in circumstances occurs, such as an increase in income.

This adjustment is designed to ensure that the child’s needs are met appropriately in line with the resources available from the obligor. As a result, courts may either automatically or upon request update child support obligations to align with the increased earnings of the obligor.

In contrast, the other options do not accurately reflect how child support typically functions in relation to changes in the obligor's income. Child support payments do not automatically decrease with an increase in income, nor does an increase only affect the obligor's expenses. Additionally, child support is not static and thus does not remain unchanged if a significant income change occurs. Therefore, it is crucial to recognize the obligation to adjust support in the interest of the child’s needs and well-being.
