Frequently Asked Questions

How is child support calculated?

Can child support be modified?
Yes, child support can be modified when there is a material change in circumstances such as job loss, income change, or change in custody.
Does overnight custody affect child support?
Yes, in many states the number of overnights the payor has reduces the support obligation, typically after exceeding a threshold like 110 nights.
