Frequently Asked Questions
Child Support in Texas
Discover what you need to know about Child Support Laws in Texas.
Texas calculates child support under Texas Family Code Chapter 154, using a percentage-of-income guideline (not an income shares model). The court starts with the obligor’s “net resources” and applies guideline percentages.
The calculation generally considers:
The paying parent’s monthly net resources (as defined by statute)
The number of children before the court
Texas guideline percentage rates (e.g., 20% for one child, 25% for two, etc.)
The guideline “cap” (a maximum amount of net resources to which the percentages apply)
Medical support (health insurance and/or cash medical support) and other court-ordered add-ons
Any court-approved deviations (based on the child’s needs and case facts)
For an estimate tailored to your situation, you can use the Deliberately.ai child support calculator above—but only a court order is legally binding.
Child support in Texas is commonly influenced by:
The obligor’s monthly net resources
The number of children and the guideline percentage applied
Whether income exceeds the guideline cap (courts can deviate above-guideline in some situations)
Health insurance and cash medical support allocations
Childcare or other child-related expenses (if ordered)
Court-approved deviations (special needs, extraordinary expenses, travel, etc.)
Self-employment income, bonuses, commissions, and fluctuating earnings may require detailed documentation.
There is no universal amount.
The final figure depends on:
The paying parent’s net resources
The guideline percentage based on the number of children
Whether the case involves the guideline cap
Medical support and other ordered add-ons
Any approved deviation
For a reliable estimate before filing or negotiating, use the Deliberately.ai calculator above—keeping in mind the court has final authority.
In Texas, child support generally continues until the child turns 18 or graduates from high school, whichever occurs later.
Always review your specific court order for termination terms.
Not necessarily.
Support may continue until high school graduation if the child is still enrolled.
Wage withholding may continue unless the order is properly terminated/updated through the required process.
Any unpaid arrears remain owed even after the obligation period ends.
Yes.
A child support order may be modified when:
There is a material and substantial change in circumstances, or
The order is at least 3 years old and the guideline amount would differ by 20% or $100 (whichever is applicable under the standard).
Modifications generally apply from the date a petition to modify is filed.
Timeframes depend on:
Whether the case is contested
Court/agency scheduling
Court availability
Whether income documentation is disputed
Uncontested cases may resolve more quickly.
Basic child support is intended to cover typical child-rearing costs such as:
Housing
Food
Clothing
Transportation
Utilities
Ordinary living expenses
Separate allocations commonly include:
Health insurance for the child
Cash medical support (when applicable)
Unreimbursed medical expenses (if ordered)
Other court-ordered child-related expenses
It can—but only if:
The expense is included in the support calculation/order, and
The order clearly reflects how medical support is allocated
Paying expenses outside the court order does not automatically reduce the monthly obligation.
Texas generally uses “net resources” (not just wages), as defined by statute. Net resources can include wages/salary and may include other income depending on the situation and allowable deductions.
If a parent is voluntarily unemployed or underemployed, the court may impute income based on earning capacity.
Nonpayment may result in enforcement actions such as:
Wage withholding/garnishment
Tax refund intercept
Bank account levy
Driver’s license suspension
Professional license suspension
Passport denial
Contempt proceedings
Arrears continue accumulating until fully paid.
Arrears generally:
Remain owed until paid in full
Can be collected through enforcement tools
Do not disappear when the child reaches adulthood
Yes.
Income withholding is common, and enforcement tools may be used when necessary.
Not automatically.
Texas guideline child support is primarily based on the obligor’s net resources and the percentage guideline, not directly on overnight counts the way some income-shares states do. Parenting time can still matter for deviations in appropriate cases.
In limited cases, yes.
If a child has a severe disability that prevents self-support, courts may consider continued support.
Parents generally cannot privately override a court order.
Any agreement must be approved by the court to be legally enforceable.
A lawyer is not required for straightforward cases, but it is strongly recommended when:
Income is disputed
Self-employment is involved
Arrears exist
A deviation is requested
Custody is contested
You will typically need:
Recent pay stubs
Federal tax returns
Proof of health insurance costs
Documentation of other income (bonuses, commissions, self-employment, rental, etc.)
Existing court orders
Incomplete documentation can delay proceedings.

How Long Does a Child Support Modification Take in Louisiana?
Michigan calculates child support using the Michigan Child Support Formula (MCSF), which Michigan courts are required to use when setting or changing child support.
Michigan’s approach is based on an income-shares model, meaning the formula estimates what parents would have contributed toward the child if they lived together, then allocates responsibility between parents.
The calculation is based on:
Both parents’ incomes (used to determine each parent’s support share)
Number of children
A statewide support schedule/formula inputs (per MCSF)
Parenting time / overnights (Michigan applies a parental time offset when overnights can be determined)
Medical support (health insurance and ordinary medical considerations)
Work-related childcare expenses
Other adjustments and court-approved deviations under the MCSF
