"Under Texas law, the monthly child support net resource figure that is used to determine child support is capped. The net resource cap is $7,500 a month, which means that the maximum child support for two children is $1,875 per month (25 percent of $7,500). The payer of child support is also required to pay for the child's health insurance premium, because the payer is allowed to deduct that cost from gross income from all sources in determining net resource."
