How Does Child Support for Multiple Families Work in Texas?

 Posted on April 14, 2026 in Child Support

If you have children from more than one relationship, you may be worried that you’re going to be slammed with child support payments. The good news is that Texas understands that there are limits to how much of a parent’s paycheck can realistically go to child support, and they have a different system for determining how large payments will be for parents of two families. If you’ll be paying child support to more than one person, a Tarrant County child support attorney can help you know what your payment is likely to be.

How Does Texas Calculate Child Support for a Single Family?

Texas uses a percentage-of-income model to calculate child support for just one family. Under the Texas Family Code Section 154.125, the court starts with your net monthly resources. This is basically your income after taxes and certain deductions. It then applies a set percentage based on how many children you're supporting.

For one child, support is 20 percent of your net resources. For two children, it's 25 percent, and it increases from there. The percentages cap out at 40 percent of net monthly resources for five or more children.

Net resources can include things like:

• Wages and salaries
• Self-employment income
• Rental income
• Social Security benefits
• Veterans' benefits

The court subtracts Social Security taxes, federal income taxes (based on tax tables), union dues, and health insurance premiums paid for the child from your gross income to arrive at your net amount.

What Happens When You Have Children in More Than One Household?

Texas law has a separate but related system for children from different relationships who live in separate households. Per Texas Family Code Section 154.128, the court uses an adjusted calculation that is intended to reduce the percentage applied to your net income. This makes the resulting support amount less than if the standard support percentages had been used for all the children at once.

The first step for multi-household support is to figure out how much the person would be paying in child support if all the children lived in one household. This amount is then divided by the number of children the person has. Once the amount-per-child has been determined, it is multiplied by the number of children in the household that first started receiving support.

The resulting amount, called a credit, is then subtracted from the net monthly income of the paying parent, and the normal child support percentages are applied to this adjusted net monthly income for the number of children in the other household. The credit provides a discount of sorts to the paying parent by making the net income smaller. For example, twenty percent of $4,500 will be a smaller amount than twenty percent of $5000.

If you hear the phrases "before the court" or "not before the court," these are in reference to which children are in which household. The children in the first household to receive support are referred to as "not before the court." The children of the second household to receive support are "before the court." 

Will the Court Automatically Adjust My Child Support Payments If I’m Supporting Two Sets of Kids?

Adjustments for multiple child support payments aren't automatic. You will need to file a motion with the court to get your support orders updated. You’ll also need to provide documentation of your existing support obligations.

If you have further questions about your specific situation, speaking to a family law professional is a good choice. If you believe the support orders are incorrect or not realistic with your finances, you may need to go through an appeal process, which takes more time. Having someone to walk you through your old and new orders is a great way to make sure they’re fair and accurate.
