Child Support with Children from Previous Relationships

Child support calculations become more complex when the obligor — the parent who pays support — has children from more than one relationship. Texas law addresses this situation through the "multiple household" guidelines found in Section 154.128 and Section 154.129 of the Texas Family Code. These provisions ensure that the support obligation is adjusted fairly to reflect the obligor's total parental responsibilities.

When an obligor has other children they are legally obligated to support — whether through a prior court order or children living in their current household — the guideline percentages are reduced. For example, if the court is calculating support for one child before the court and the obligor has one other child they are obligated to support, the guideline drops from 20 percent to 17.50 percent. With two other children, it drops to 16 percent. The reductions continue as the number of other supported children increases.

The Texas Family Code provides a detailed table of these adjusted percentages. For two children before the court with one other child to support, the guideline is 22.50 percent rather than the standard 25 percent. For three children before the court with one other child, it is 27.38 percent rather than 30 percent. These adjustments recognize that the obligor's resources must be spread across all of their children, not concentrated on those before the current court.

It is important to note that the obligor bears the burden of proving the existence of other children they are obligated to support. A court order establishing paternity and support, birth certificates, and evidence of actual financial support for children in the current household are all relevant. Simply having other children does not automatically trigger the reduced percentages — the obligor must demonstrate a legal obligation or actual support.

These calculations can be confusing and are frequently a source of disputes in child support cases. When multiple households are involved, careful attention to the statutory tables and accurate documentation of all support obligations is essential for arriving at a fair and legally correct support amount.
