Understanding Child Support Decisions In Texas Courts
Child support is one of the most important, and most misunderstood, issues parents face during a divorce, custody case, or paternity action.
Parents throughout Harris County, Montgomery County, Houston, The Woodlands, Spring, Conroe, Magnolia, Tomball, Cypress, and surrounding communities who are unmarried or are facing divorce or child custody proceedings often ask the same question: How is child support calculated in Texas?
Texas child support laws are designed to ensure children receive consistent financial support from both parents, regardless of living arrangements. While many people assume child support is simply a percentage of income, the actual calculation can be more complex. Texas courts evaluate income, deductions, medical support, and the unique circumstances of each family.
What Is Child Support?
Child support is a court-ordered payment intended to meet a child’s basic needs after parents separate or divorce. Under Texas law, both parents have a legal duty to support their children. Typically, the parent who does not have primary custody pays child support to the parent who has the child most of the time.
Child support helps cover essential expenses such as:
- Housing
- Food
- Clothing
- Education
- Transportation
- Medical care
- Daily living costs
The goal is to ensure children continue receiving financial support from both parents.
How Texas Courts Calculate Child Support
Texas courts follow guidelines established by the Texas Family Code. The calculation generally involves two steps:
- Determining the paying parent’s net monthly resources
- Applying the guideline percentage based on the number of children
This guideline system is used throughout Texas, including courts serving Harris County and Montgomery County.
Net Resources
Net resources represent the income available for child support after certain deductions. Net resources may include salary, wages, overtime pay, bonuses, commissions, self-employment income, rental income, retirement income, unemployment benefits, and certain disability benefits. Courts subtract allowable deductions to determine net resources.
For parents with fluctuating income – such as business owners, contractors, or commission-based employees – calculating net resources may require detailed financial documentation.
Texas Child Support Guideline Percentages
| Number of Children | Guideline Percentage of Net Resources |
|---|---|
| One child | 20% |
| Two children | 25% |
| Three children | 30% |
| Four children | 35% |
| Five children | 40% |
| Six or more children | Not less than 40% |
These percentages are a starting point; courts may adjust support when circumstances justify deviation. For example: If the parents in a divorce have one child together – but if the parent who will be paying child support also has a child support obligation for another child in another case – then the guideline percentage for the one child of the divorce would be 17.5% instead of 20%.
Deviations from the Guidelines
Courts may deviate from guideline support when applying the standard calculation would be unfair or inappropriate. Factors that may justify deviation include:
- Extraordinary medical needs
- Special educational expenses
- Childcare costs
- Travel expenses for visitation
- The child’s unique needs
- Financial resources available to the child
- Other children the parent supports
Every case is fact-specific, and courts aim to reach outcomes that serve the child’s best interests.
Overtime, Bonuses, and Commissions
Courts may include overtime income if it is regular and recurring. Courts may include bonuses and commissions when they are frequent or predictable. Accurate financial records are essential when variable income is involved.
Self-Employment Income
Self-employment can complicate child support calculations. Courts may review:
- Profit and loss statements
- Business records
- Bank statements
- Tax returns
- Other financial disclosures
The goal is to determine true available income—not just what appears on paper.
Medical Support
Texas courts typically address medical support in addition to monthly child support. A parent may be ordered to provide health insurance if available at a reasonable cost. Courts may also order parents to share uninsured medical expenses. Medical support obligations are separate from standard child support payments.
Duration of Child Support
Child support usually continues until the child turns 18 and graduates from high school. Texas law does not require child support for college education or for any education beyond high school. Support may continue longer for children with disabilities requiring ongoing care. Specific circumstances may affect the duration of child support.
Additional Child Support Agreements
Parents will sometimes agree to include additional child support provisions in their Court Orders for such expenses as extracurricular activities, private school, automobiles for teenaged children, etc. The court will usually approve these agreements of the parties; however, most courts will not ordinarily order these types of provisions on its own. The specific child support obligations to which Texas courts concern themselves are those support obligations for monthly or periodic support in a fixed dollar amount, and for children’s health care.
Modifications
Texas law allows modifications when circumstances substantially change. Common reasons include job loss, income changes, medical issues, and changes in the child’s needs. Modifications require court approval; informal agreements are not legally binding.
Enforcement
Failure to pay child support can result in serious consequences. Enforcement options include wage withholding, property liens, license suspensions, contempt proceedings, and attorney’s fees. Parents facing financial hardship should seek legal assistance promptly.
