Parents in the Houston metro area—including Friendswood, Clear Lake, and Pearland—often have questions when child support becomes part of a divorce or custody case. Texas law provides a structured system for calculating support, enforcing orders, and modifying obligations when circumstances change, but applying those rules to your family’s situation may be complex.

This page explains how child support generally works under Texas law, with a focus on families in and around Houston. It is for informational purposes only and does not constitute legal advice for your specific case.

Key Takeaways

Texas uses statutory guidelines to calculate most child support obligations based on the paying parent’s net resources and the number of children.
Net resources typically include wages, self‑employment income, certain benefits, and other income streams, with specific exclusions.
Courts may deviate from guideline amounts when the guideline number would be unjust or inappropriate under the circumstances.
Support is usually paid through wage withholding and processed by the Texas Child Support Disbursement Unit.
If a parent falls behind, enforcement tools can include license suspension, wage garnishment, liens, and contempt proceedings.
Child support orders may be modified when there is a material and substantial change in circumstances or when the three‑year/20%/$100 guideline test is met.

Quick Answer

In most Houston‑area cases, the court first determines the paying parent’s monthly net resources under the Texas Family Code. A percentage is then applied—typically 20% for one child, 25% for two, 30% for three, and so on, subject to a statutory cap. The court may adjust this amount based on the child’s best interests and special circumstances.

If the paying parent does not comply, the other parent (or the Texas Office of the Attorney General) may seek enforcement through wage withholding, judgments for arrears, license suspension, and, in serious cases, contempt. A support order may later be increased or decreased if there is a significant change in income, health needs, custody arrangements, or if enough time has passed to apply updated guideline figures.

How Child Support Works Under Texas Law

Legal framework for child support

In Texas, child support is governed primarily by the Texas Family Code, including:

Guideline child support and best interest factors: Tex. Fam. Code ch. 154
Possession and access (parenting time), which often interacts with support: Tex. Fam. Code ch. 153

Houston‑area courts—including those in Harris, Galveston, Brazoria, and Fort Bend Counties—are required to apply these statutes. Judges have discretion within this framework but must base decisions on the child’s best interests.

Who typically pays child support?

The parent ordered to pay support is commonly referred to as the “obligor.” The parent receiving support (often the primary residential parent) is the “obligee.” Either parent can be an obligor or obligee depending on custody arrangements and relative incomes.

The court may order:

One parent to pay the other parent directly (usually via the state disbursement unit), or
In some cases, both parents to provide support (for example, in split or shared custody situations).

Parents cannot permanently waive child support, because support is considered a right of the child rather than a right of the parent.

Calculating Child Support in the Houston Metro

Step 1: Determining the obligor’s net resources

Texas guideline support is based on the obligor’s “net resources,” not gross income. Under Tex. Fam. Code § 154.062, resources generally include:

Wages and salary (including overtime and bonuses)
Commissions, tips, and self‑employment earnings
Rental income, royalties, and dividends
Certain retirement benefits, pensions, and annuities
Unemployment benefits, disability benefits, and some other periodic income

Some sources are excluded, such as:

Means‑tested public assistance (for example, certain Supplemental Security Income)
Foster care payments
Some returns of principal or capital, depending on context

From gross resources, the court subtracts items specified in Tex. Fam. Code § 154.062(d), such as:

Federal income tax (using a single person, standard deduction basis unless evidence supports a different calculation)
Social Security taxes or mandatory retirement contributions
Union dues
The obligor’s health insurance or cash medical support for the child

The result is the obligor’s monthly net resources. This figure is subject to a statutory cap, which is periodically adjusted by the Texas Office of the Attorney General under Tex. Fam. Code § 154.125(a‑1).

Step 2: Applying the guideline percentage

Once monthly net resources are established (up to the cap), Texas guideline percentages in Tex. Fam. Code § 154.125 are generally:

1 child – 20% of net resources
2 children – 25% of net resources
3 children – 30% of net resources
4 children – 35% of net resources
5 children – 40% of net resources
6+ children – not less than the amount for 5 children

If the obligor has other children to support who are not the subject of the current case, the percentage is adjusted downward under Tex. Fam. Code § 154.129.

These percentages are presumptively reasonable and in the child’s best interest, but they are not absolute. The court may deviate based on statutory factors.

Step 3: Considering the child’s and parents’ circumstances

Under Tex. Fam. Code § 154.123, the court may consider many factors when deciding whether to follow or deviate from the guideline amount, including:

The child’s age and needs (educational, medical, special needs)
The ability of the parents to contribute to support
Any financial resources available for the child’s benefit
Time of possession and access between parents
Child care expenses
Alimony or spousal maintenance obligations
Other children the obligor or obligee must support
Costs of travel for visitation (especially relevant in large metros and long‑distance cases)
Any special or extraordinary educational, health care, or other expenses

In the Houston metro, factors such as high medical costs in the Texas Medical Center area, specialized schooling, or substantial commuting/travel expenses for exchanges may be especially important.

Example: Simplified guideline calculation

Assume:

Obligor’s monthly gross income from employment: $6,000
After allowable deductions, net resources (under the statute): $4,500
One child, no other children to support

Guideline support would often be:

20% of $4,500 = $900 per month

The judge may then adjust that figure up or down if there are significant special circumstances, but in many cases the guideline amount becomes the order.

Health Insurance and Medical Support

Texas law requires that child support orders include provisions for medical and dental support. Under Tex. Fam. Code §§ 154.181–154.187, the court generally orders:

One parent to provide health insurance for the child if it is available at a reasonable cost, and
Allocation of uninsured medical expenses between the parents, often 50/50 but subject to the court’s discretion.

The cost of health insurance for the child (the child’s portion only) is typically factored into the net resources calculation. The court may also order cash medical support if insurance is not available to a parent at a reasonable cost.

How Child Support Is Paid in the Houston Area

Wage withholding

Texas law strongly favors wage withholding (income withholding) as the default payment method. Under Tex. Fam. Code ch. 158, most child support orders include a requirement that employers withhold support from the obligor’s paycheck and send it to the Texas Child Support Disbursement Unit.

For Houston‑area parents, this means:

Your employer will receive an income withholding order.
Support is deducted and forwarded automatically, reducing the chances of missed payments.

Texas Child Support Disbursement Unit and recordkeeping

Payments typically flow through:

The Texas Child Support Disbursement Unit (statewide processing center), which logs payments and disburses them to the obligee.

This system creates an official record of payments that can become critical in enforcement or modification proceedings. Parents should generally avoid private, off‑the‑record payments unless clearly documented and approved by the court, as informal payments may be disputed later.

Direct payments and concerns

Although some parties attempt to make or accept direct payments (cash, apps, checks) outside the system, this may lead to:

Disagreements about whether payment was made
Difficulty proving payment in court

If a court‑ordered payment path exists, it is usually safest to follow it so there is a reliable official record.

Enforcement of Child Support Orders in the Houston Metro

When child support is not paid as ordered, the obligee (or the Texas Office of the Attorney General, if involved) may file an enforcement action under Tex. Fam. Code ch. 157.

Common enforcement tools

Texas courts and agencies have multiple methods to enforce support:

Wage garnishment / income withholding — If wage withholding is not already in place or is not capturing enough income, the court may strengthen or modify withholding orders.
Judgments for arrearages — Unpaid support (arrears) may be reduced to a money judgment, sometimes with interest, which can be collected like other judgments.
Liens against property — Under Tex. Fam. Code §§ 157.311–157.331, child support liens may attach to non‑exempt real property and other assets. This can affect home sales or refinancing in Houston’s active real estate market.
License suspension — Professional, driver’s, hunting, and fishing licenses may be subject to suspension in some circumstances when a parent falls significantly behind.
Interception of tax refunds and other payments — Certain federal or state payments (such as tax refunds) may be intercepted and applied to child support arrears.
Contempt proceedings — Under Tex. Fam. Code § 157.001 and related provisions, a court may hold an obligor in contempt for willful failure to pay court‑ordered support. This may result in fines, community service, or jail time in serious cases, although courts typically encourage compliance and payment plans before considering severe measures.

Defenses and clarifications

An obligor facing enforcement may raise issues such as:

Mistaken accounting (payments not credited properly)
Inability to pay due to job loss or disability (which may not erase arrears but may influence remedies)
Disputes about whether certain payments count as support

These issues are very fact‑specific. A local family lawyer can help gather records, challenge incorrect balances, and present defenses.

Local court practices

Houston‑area courts may:

Set compliance review dates to monitor payment plans
Order lump‑sum payments, increased withholding, or additional security for future payments
Emphasize co‑parenting responsibilities and the child’s needs when fashioning enforcement remedies

Because every court and judge may handle enforcement slightly differently, local experience can be important in planning an enforcement or defense strategy.

Modifying Child Support Orders

Child support orders are not set in stone. Over time, jobs change, children grow, and needs evolve. Texas law recognizes this and allows modification under Tex. Fam. Code ch. 156.

When can child support be modified?

There are two primary paths to modification under Tex. Fam. Code § 156.401:

Material and substantial change in circumstances — The court may modify a support order if there has been a material and substantial change in circumstances of the child, a person affected by the order (usually either parent), or another child supported by the obligor. Examples might include significant increase or decrease in a parent’s income, involuntary job loss or long‑term reduction in hours, major changes in the child’s medical or educational needs, or changes in custody or possession schedule.
Three‑year / 20% / $100 guideline test — A court may modify if at least three years have passed since the last order was rendered or last modified, and the monthly support amount differs by either 20% or $100 from the amount that would be awarded under the current guidelines.

Process for seeking modification

To change support in the Houston metro, a parent generally must:

File a petition to modify in the court that issued the original order (or to which the case has been transferred).
Serve the other parent with proper notice of the proceeding.
Gather evidence of the changed circumstances—pay stubs, tax returns, medical bills, custody schedules, etc.
Attend hearings or mediation as required by the court.

The judge will then decide whether a material and substantial change exists or whether the three‑year/20%/$100 rule applies, and what new support amount, if any, is appropriate.

Informal agreements vs. formal modifications

Parents sometimes agree informally to reduce or increase support because of life changes. However, unless the change is reflected in a revised court order:

The original court‑ordered amount generally remains legally enforceable.
An obligor may still be held responsible for the full original amount, even if the obligee agreed to accept less.

For this reason, it is usually advisable to seek a formal modification when circumstances significantly change.

How Custody and Parenting Time Affect Support

Although Texas guideline child support is primarily based on income, parenting time (possession and access) can influence the overall analysis.

Standard vs. expanded schedules

Under Tex. Fam. Code ch. 153, Texas provides standard possession orders (SPO) and may also order expanded or custom schedules. In the Houston metro, many cases involve:

Standard possession (weekends and some weekdays, plus holidays and summer)
Expanded standard (extended time on weekends and mid‑week)
Custom arrangements tailored to work schedules, school calendars, or long‑distance travel

The court may consider:

The amount of time each parent spends with the child
Travel expenses (for example, when parents live in different cities or parts of the metro)
Shared or nearly equal possession schedules

In more unusual situations, such as truly equal time and similar incomes, the court might find the guideline amount inappropriate and adjust support accordingly.

Relocation and long‑distance issues

Houston’s large geographic area and mobile workforce sometimes lead to relocation disputes. If one parent moves farther away and travel costs rise substantially, the court may:

Revisit child support to account for increased transportation expenses
Allocate travel costs between the parents

Any proposed relocation or significant change to the parenting plan should be discussed with counsel, as it may have ripple effects on support and custody.

Special Situations Affecting Child Support

High‑income earners in the Houston area

The statutory guideline applies only up to the net resources cap established under Tex. Fam. Code § 154.125(a‑1). For parents whose income exceeds that cap (common in certain Houston industries like energy, medicine, or professional services):

The court generally applies the guideline percentage to the capped amount.
The court may order additional support above the cap if the child’s proven needs justify it under Tex. Fam. Code § 154.126.

High‑income cases often involve detailed proof of the child’s reasonable needs and lifestyle, as well as complex compensation structures (bonuses, stock, partnership draws, etc.).

Self‑employed parents and business owners

For self‑employed parents and business owners, determining “net resources” can be more complex:

Courts may examine business financials, tax returns, and evidence of in‑kind benefits (company car, housing, travel, etc.).
Excessive business deductions may be scrutinized to ensure income is not artificially reduced.

Parents who own businesses and are going through divorce may also wish to review business owner divorce, as valuation and support issues often intersect.

Children with special needs

If a child has significant medical or educational needs, the court may:

Order support above guideline amounts to cover therapies, specialized schooling, or equipment
Carefully allocate responsibility for health insurance, uncovered medical expenses, and transportation to treatment

Child support for an adult disabled child may continue beyond age 18 in some circumstances under Tex. Fam. Code § 154.302, if the disability existed or was known before the child turned 18.

Duration of child support

Under Tex. Fam. Code § 154.001, support typically continues until the earliest of:

The child turning 18 or graduating from high school (whichever occurs later, with some limitations);
The child’s marriage, emancipation, or death.

Support may continue indefinitely for an adult disabled child who requires substantial care and personal supervision and cannot support themselves, as provided in Tex. Fam. Code § 154.302.

FAQ

How is child support usually calculated for Houston families?

For most families, the court determines the paying parent’s monthly net resources under Tex. Fam. Code § 154.062 and applies guideline percentages (20% for one child, 25% for two, 30% for three, etc., up to a statutory cap) as provided in Tex. Fam. Code § 154.125. The court may adjust this amount if the guideline figure would be unjust or inappropriate.

Can parents agree to a different child support amount than the Texas guidelines?

Yes, parents may agree to an amount different from the guideline figure, but the judge must still approve the agreement and find that it is in the child’s best interest under Tex. Fam. Code § 154.124. The court is not required to accept an agreement that it considers inadequate or excessive.

What if the paying parent loses a job in the Houston area?

If the obligor loses a job or suffers a significant income reduction, they may request a modification of the support order under Tex. Fam. Code § 156.401 based on a material and substantial change in circumstances. Until the court signs a new order, the existing support amount remains in effect and continues to accrue.

How long do I have to enforce unpaid child support in Texas?

Texas allows enforcement of unpaid child support for a considerable time. Under Tex. Fam. Code § 157.005, a motion to confirm arrears may generally be filed up to 10 years after the child turns 18 or the support obligation ends, whichever is later. Specific deadlines and strategies should be reviewed with counsel.

Does child support automatically end when my child turns 18?

Not always. Under Tex. Fam. Code § 154.002, support generally continues until the child turns 18 or graduates from high school, whichever occurs later (subject to certain limits), or until the child marries, is emancipated, or dies. For a disabled child who cannot support themselves, support may continue indefinitely under Tex. Fam. Code § 154.302.

Can child support be changed if our custody schedule changes?

Yes. A significant change in the possession and access schedule may qualify as a material and substantial change in circumstances under Tex. Fam. Code § 156.401, justifying a modification of support. The court will consider the new schedule, each parent’s income, and the child’s needs in setting a revised amount.

Will the court look at my new spouse’s income when setting child support?

Generally, no. Under Tex. Fam. Code § 154.069, a court may not consider a new spouse’s income as part of the obligor’s net resources. However, overall household circumstances may sometimes be relevant to certain best‑interest considerations.
