Texas child support follows a formula, but the amount a court orders depends on evidence you gather and present. A Houston child support lawyer at Kamal Law Firm Family Law and Immigration Lawyers can help you open a support case, respond to one, or return to court when an existing order no longer fits your family. We represent parents across Harris County, Fort Bend County, and surrounding communities from our office on Savoy Drive.
Some parents come to us before any order exists, while others hold an order set years ago that no longer reflects what either household earns. Either way, the result turns on documented income and correctly applied guidelines. Call (713) 524-4529 to talk through your options in a free case evaluation.
Why Choose Kamal Law Firm, PLLC for Child Support Cases in Houston?
We have spent more than 10 years guiding Houston area families through family law matters, and support questions run through most of the cases we handle.
Our founder, Farah Kamal, is a certified mediator, a member of the State Bar of Texas Diversity Committee, and an attorney admitted to the U.S. District Court. That mediation background matters here, since disputes over income, childcare costs, or insurance premiums can often be settled in negotiation rather than a contested hearing.
Our team is fluent in Spanish, Urdu, and Hindi, so we can explain the process in the language a client prefers. We also answer client questions within 24 hours, because support cases move on court deadlines that do not wait.
How Texas Calculates Child Support
Texas uses a percentage model rather than a shared income model. The court starts with the paying parent’s monthly net resources, applies a percentage set by statute, and then decides whether that figure fits the child’s situation.
Under Texas Family Code Chapter 154, a guideline amount is presumed reasonable and in the child’s best interest. A parent who wants a different number carries the burden of showing that the guideline result would be unjust or inappropriate.
What Counts As Net Resources
Net resources extend beyond a paycheck. The statute counts wages, commissions, overtime, tips, bonuses, self-employment income, interest, dividends, net rental income, retirement benefits, unemployment benefits, capital gains, gifts, and prizes.
From that total, the court subtracts a defined list:
- Social Security taxes.
- Federal income tax calculated for a single person claiming one exemption and the standard deduction.
- Union dues.
- The cost of health and dental insurance ordered for the child.
- Nondiscretionary retirement contributions, when the parent pays no Social Security taxes.
A new spouse’s income is excluded from the calculation entirely, and courts may not subtract a new spouse’s needs from either parent’s net resources.
Guideline Percentages and the Net Resources Cap
When monthly net resources reach $1,000 or more, the guideline schedule sets the percentages at 20 percent for one child, 25 percent for two, 30 percent for three, 35 percent for four, and 40 percent for five. Six or more children draw no less than the amount for five. A reduced schedule applies to monthly net resources below $1,000.
Those percentages apply only up to a statutory ceiling. Effective September 1, 2025, the Office of the Attorney General raised that ceiling from $9,200 to $11,700 in monthly net resources. Income above the cap is not automatically counted; instead, a court may order additional support based on the child’s proven needs.
Medical and Dental Support are Ordered Separately
Health and dental coverage are not folded into the percentage. The guidelines assume a court will order medical and dental support in addition to the base amount, and both are enforceable like child support.
Courts also allocate uninsured costs, dividing deductibles, copayments, and out-of-pocket medical, vision, and dental expenses between the parents according to their circumstances.
Filing a Child Support Petition in Houston
Two roads lead to a Texas support order. You can ask the Office of the Attorney General to open a case, which proceeds through the Child Support Review Process, an in-office negotiation that ends with a proposed order sent to a judge.
Filing your own suit is the other route. It usually moves faster and gives you more say over conservatorship terms and possession schedules. Agency cases cost nothing but move on the agency’s timeline.
Where To File Your Child Support Case
Houston support suits are filed with the Harris County District Clerk and heard in the family district courts. Attorney General cases are assigned to the IV-D child support courts in the Family Law Center at 1115 Congress.
A first support order generally follows this sequence:
- Confirm parentage through an acknowledgment of paternity or a court finding.
- File an original petition in the county with jurisdiction over the child.
- Serve the other parent and wait for an answer.
- Exchange financial records, including two years of tax returns, pay stubs, and a financial statement.
- Attend mediation or negotiate a proposed order.
- Present the agreement, or try contested issues, at a hearing.
Retroactive Child Support
A court can reach backward. Where no prior order existed, a judge may order retroactive support, and an award covering the four years before filing is presumed reasonable.
That presumption can be rebutted when the paying parent knew of the child and worked to avoid a support obligation.
Modifying a Child Support Order in Texas
An existing order does not adjust itself when a job changes. Modification requires a new court order, and Texas Family Code Chapter 156 gives parents two separate paths to one.
The Material and Substantial Change Standard
The first path asks whether circumstances have materially and substantially changed since the order was rendered or since a mediated settlement agreement was signed. Job loss, a significant raise, a new child, a changed possession schedule, and rising medical needs are all common grounds.
The statute treats one situation as a change by definition: Incarceration of the paying parent for more than 180 days qualifies automatically.
The Three-Year Rule
The second path skips the change analysis. A court may modify without proof of changed circumstances when three years have passed since the last order. The monthly amount must also differ from the current guideline figure by 20 percent or $100.
One exception catches parents off guard. Where your order was an agreed order that already departed from the guidelines, the three-year rule is unavailable, and you must show a material and substantial change.
What the Higher Cap Means for Older Orders
Orders set under the previous $9,200 ceiling did not change on their own. A parent whose income sat at or above the former cap may now find the guideline figure differs from the current order by more than 20 percent.
Timing matters here. Modified support runs from the earlier of service or the other parent’s appearance in the suit, so months that pass before filing are not recalculated.
Child Support Matters We Handle in Houston
Our attorneys work across the range of support issues, including:
- Establishing a first support order, with or without a divorce.
- Modifying an order upward or downward after an income change.
- Enforcement when payments stop, including income withholding.
- Disputes over self-employment income and unreported earnings.
- Medical support, dental support, and uninsured expense allocation.
- Support for an adult child with a disability.
- Termination of support when a child graduates or turns 18.
Several of these matters overlap with custody, and we address both together rather than opening two cases.
Frequently Asked Questions About Houston Child Support
How long does child support last in Texas?
Support generally continues until the child turns 18 or graduates from high school, whichever happens later. It can end sooner if the child marries, is emancipated, or dies.
Can we agree on an amount instead of using the guidelines?
Yes. Parents may sign a written agreement that deviates from the guidelines, and a court will enter a corresponding order when the judge finds that those terms serve the child’s best interests.
What if the other parent is self-employed or paid in cash?
Self-employment income counts, calculated as business income minus ordinary and necessary expenses. Courts may disregard depreciation and other deductions that reduce taxable income without reducing cash flow.
Does support change if the children stay with me more often?
Possession time is one factor a court weighs when deciding whether a guideline amount is appropriate. By itself, it does not reduce the percentage.
Do I keep paying if I lose my job?
The order stays in force until a court changes it, so payments continue to accrue. Should your income drop, file for modification promptly, because any adjustment applies only from service or appearance forward.
Can the Attorney General’s office and a private attorney both be involved?
Yes. The Attorney General represents the State’s interest in the support case rather than either parent, so many parents retain private counsel to protect their own position while an agency case is open.
