Child Support in Texas — What Parents Need to Know

Texas figures child support using statutory guidelines that rest on the obligor's net monthly income together with how many children are being supported. Courts ordinarily follow these guidelines, though they may depart from them in light of the child's needs, the cost of health insurance, childcare expenses, and other relevant considerations.

To establish a child support order, the parties must either reach an agreement that is confirmed by court order, or the court must decide the matter after a hearing. When an order goes unpaid, enforcement may bring wage garnishment, license suspension, contempt proceedings, and, in serious cases, jail. To modify an order, you must show a material and substantial change in circumstances since the last order was signed.

Our firm takes on child support cases at every phase — first-time establishment, enforcement when payments stop, and modification when things change. We aim to protect your children's financial security while making sure the legal process is handled correctly from day one.


When Both Parents Agree — Flat-Fee Modifications

Where the parents have already agreed on a child support modification — for instance an income-based adjustment or a change connected to a new custody arrangement — the matter can frequently be resolved more efficiently and for less than a contested modification would cost.

An informal agreement between parents is not legally enforceable, even when it is put in writing. Enforcement through contempt or wage withholding is only possible under a court-signed order. Once you and the other parent have settled on changes, entering those changes properly as a court order is the crucial final step.

Eligible agreed child support modifications can be handled through our uncontested divorce service — attorney-guided, flat-fee, and built for parents who already agree on every term. A licensed attorney handles the drafting, filing, and court approval from beginning to end.

Establishing, Enforcing & Modifying Child Support in Texas

Establishing Support

When there is no existing child support order, the court must create one. That means calculating the obligor's net income, applying the guideline percentages, and handling add-ons such as health insurance and childcare. Doing this correctly at the outset — accounting for every income source and the proper deductions — sets your financial position for years to come.

Enforcing an Order

If a parent stops paying court-ordered child support, Texas courts can draw on powerful enforcement tools — wage withholding, tax refund interception, suspension of licenses (driver's, professional, recreational), and contempt of court, which may lead to jail time. Overdue support builds up as a judgment that carries interest. We can act fast to enforce your order and recover arrears.

Modifying an Order

Texas permits modification where a material and substantial change in circumstances has occurred — for example a notable rise or drop in either parent's income, a change in the child's needs, or a change in the custody arrangement. Any modification has to be made through a court order, since informal agreements between parents carry no legal force.

How Texas Calculates Child Support

20% 1 Child
25% 2 Children
30% 3 Children
35% 4 Children
40% 5+ Children

These percentages are applied to net monthly income — gross income after federal taxes, social security, state income tax, union dues, and health insurance premiums are deducted. A court may also order extra amounts for health insurance, unreimbursed medical costs, and childcare, and it may depart from the guidelines in light of the child's particular needs and other relevant factors.

Key Child Support Concepts in Texas

Net Monthly Income

The Texas guidelines are based on net income — gross monthly income less federal income tax, social security, Medicare, state income tax, union dues, and the cost of the child's health insurance. Calculating net income accurately is essential to arriving at the correct support amount.

Income Cap

The Texas guidelines reach only the first $9,200 of net monthly income (per recent statutory updates). Where an obligor earns more than that cap, a court may order additional support based on the child's proven needs.

Medical Support

On top of base child support, Texas courts direct a parent to carry health insurance for the child. Any unreimbursed medical expenses are usually divided between the parents in proportion to their incomes.

Arrears & Interest

Unpaid child support turns into a money judgment automatically by operation of law and gathers interest at 6% per year. Arrears never expire and stay collectible without limit — even once the child has grown up.

Interstate Support

Where the parents live in different states, the Uniform Interstate Family Support Act (UIFSA) determines which state has jurisdiction to establish or modify the order. We take on interstate child support cases and can advise on jurisdiction and enforcement across state lines.

The Child Support Process in Texas

1

Assess the Situation

We start by looking at any existing order, the income of both parties, and the child's needs — including health insurance, childcare, and special expenses. That review shapes the strategy for establishment, enforcement, or modification.

2

File or Respond

We file the right motion — a petition to establish, a motion to enforce, or a petition to modify — or answer a motion brought against you. Well-drafted pleadings protect your rights from the outset.

3

Exchange Financial Information

Each party discloses income, employment, and other relevant financial details. Making sure that disclosure is accurate and complete — and pushing back on inaccurate disclosure from the other side — is frequently where a case is won or lost.

4

Order Entered

By agreement or following a hearing, a court-signed order sets or changes the support amount, the payment method, and medical support. We make certain the order is thorough, specific, and enforceable right away through wage withholding where it applies.

Child Support FAQ — Texas

Texas applies income-based guidelines to the obligor's net monthly income, which is gross income after taxes, social security, Medicare, and health insurance premiums are subtracted. Under those guidelines the amount is 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more. Health insurance and childcare can add to that figure. Although the guidelines are the baseline in every case, a court can depart from them when the child's circumstances call for it.
Texas offers a wide range of enforcement measures. Among them are wage withholding orders, seizure of tax refunds, suspension of driver's and professional licenses, refusal of passport applications, and contempt of court — which can lead to jail time. Overdue child support (arrears) becomes a money judgment carrying 6% annual interest and never expires. An attorney can file enforcement proceedings promptly to halt non-payment and collect what is due.
Yes. To modify an order there must be a material and substantial change in circumstances since it was last set, such as a large rise or fall in income, loss of a job, a shift in the child's needs, or a change in custody. Texas additionally permits modification once three years have passed since the last order and the new guideline amount would differ by either $100 per month or 20% from the current one. The change has to be approved by the court, because informal parent-to-parent agreements cannot be enforced.
In Texas child support usually stops when the child turns 18 or finishes high school — whichever comes later — but never past age 19. It can also terminate if the child marries, has the disabilities of minority removed, dies, or enlists in the military. A parent's remarriage or the child starting college does not end it automatically. Whatever arrears are owed when support ends stay collectible.
No. A Texas court cannot order child support to pay for college expenses. Support concludes at age 18 or upon high school graduation. Parents are free to agree voluntarily to share college costs, and that agreement can be written into a final decree — but a court cannot force this duty on either parent. When you are working through a divorce or modification that involves college costs, be sure any agreement is properly set out in the court order.
The Texas guidelines reach only the first $9,200 of net monthly income (a figure adjusted periodically by statute). When an obligor earns more than the cap, a court may add support tied to the child's actual needs and documented expenses — but the guideline percentage by itself does not automatically extend to income over the cap. High-income child support cases call for careful evaluation of what a court is likely to award beyond the guideline threshold.
