Administrative Order No. 10 probably provides more Arkansas child support law than any other single document. Therefore there's no better place to start if you have questions about Arkansas child support, how its calculated, what you can deduct, etc. Here's the link to Administrative Order No. 10... http://courts.state.ar.us/pdf/admin_order10.pdf
Practice note: It appears that the child support chart is to be updated every 3 years. I think we may be overdue since the last time it was updated was 2002.
