Child Support Mediation in Texas: What You Can and Can't Negotiate

When parents separate in Texas, child support is one of the most contentious issues they face. Texas law provides a formula for calculating support — but that formula is a starting point, not a ceiling. Many families have circumstances that the standard guidelines don't fully address. Mediation gives parents the opportunity to build a child support arrangement that actually fits their family's reality.

How Texas Calculates Child Support

Texas uses a percentage-of-income formula to calculate child support. The paying parent's net monthly income is multiplied by a percentage based on the number of children:

• 1 child: 20% of net monthly income
• 2 children: 25%
• 3 children: 30%
• 4 children: 35%
• 5 or more children: 40%

The formula applies to net income up to a cap — currently $9,200 per month. Income above that cap is handled differently. There are also adjustments for parents who are already paying support for children from other relationships.

This formula works reasonably well for straightforward situations. But families are not always straightforward.

What You Can Negotiate in Mediation

Within the framework of Texas law and subject to court approval, parents can negotiate a wide range of child support provisions in mediation:

• Support amounts above the guideline — parents can always agree to more than the formula requires. This is common when one parent has significantly higher income or when the child has special needs that require additional resources.
• Division of additional expenses — the base child support amount covers basic living expenses, but medical costs, extracurricular activities, private school tuition, and other expenses can be allocated between parents in mediation.
• Health insurance — which parent carries the child on their health insurance, and how uncovered medical expenses are divided.
• College expenses — Texas courts cannot order parents to pay for college, but parents can voluntarily agree to college contribution provisions in mediation.
• Life insurance — agreements that the paying parent maintain life insurance to secure the support obligation in the event of their death.
• Modification triggers — agreements about when and how support will be reviewed or adjusted, such as when a child reaches a certain age or when a parent's income changes significantly.

What You Cannot Negotiate Away

There are limits to what parents can agree to in mediation when it comes to child support. Texas courts will not approve agreements that fall below the guideline amount without a compelling reason — and they will not approve any agreement that is not in the best interest of the child.

Parents cannot agree to waive child support entirely, or to amounts so low that they fail to meet the child's basic needs. The child's right to financial support from both parents is not something the parents can negotiate away — because that right belongs to the child, not to the parents.

When the Formula Doesn't Fit

The standard formula can produce results that feel unfair in certain situations. Mediation is particularly valuable in these cases:

• Self-employment or variable income — when one parent's income fluctuates seasonally or is difficult to document, the formula may not reflect actual financial capacity. Mediation allows both parents to negotiate an amount that accounts for the reality of variable income.
• Shared custody arrangements — when both parents have significant time with the child, a straight percentage formula may not reflect the actual cost distribution. Mediation allows parents to build a support structure that accounts for shared expenses.
• Children with special needs — children who require additional medical care, therapy, or educational support have costs that the standard formula doesn't capture. Mediation allows parents to build these costs into the support arrangement explicitly.
• High-income families — when income exceeds the guideline cap, the formula alone doesn't determine what's appropriate. Mediation allows high-income parents to negotiate support that reflects the child's actual standard of living.

Why Mediated Agreements Work Better

Child support agreements that parents build together in mediation tend to be followed more consistently than court-ordered amounts. When a parent understands why the number is what it is — when they had a voice in setting it — they are more likely to pay consistently and less likely to return to court seeking modifications.

That stability is good for children. Consistent financial support, combined with co-parents who can communicate without constant conflict, gives children the foundation they need to thrive after their parents' separation.
