How Does a Child Support Modification Differ From a Custody Modification?

Child support and custody are closely connected, but they are not the same thing. A custody order determines each parent’s rights, responsibilities, and parenting schedule, while a child support order establishes each parent’s financial obligations.
Because these issues are separate, one can be modified without changing the other. For example, a parent who loses a job or experiences a significant reduction in income may ask the court to modify child support even if the parenting schedule stays exactly the same.

In other cases, changes to conservatorship or possession may also affect child support. A parent who begins caring for a child substantially more often than under the original order may ask the court to review both the parenting arrangement and the amount of child support.

Understanding the difference helps ensure you request the appropriate modification. Depending on your circumstances, the court may consider changes to child support, conservatorship, possession and access, or more than one issue in the same case.

When Can the Harris County Family Courts Modify Child Support?

Texas law allows the Harris County Family Courts to modify child support when certain legal requirements are met. Under Texas Family Code Section 156.401, a parent generally may request a modification if either of the following applies:

• There has been a material and substantial change in circumstances affecting the child or either parent since the current order was entered.
• At least three years have passed since the order was established or last modified, and applying the current child support guidelines would change the monthly amount by either 20% or $100.

Meeting one of these requirements allows the court to consider a modification, but it does not guarantee that support will change. The judge reviews the facts, the evidence, and the applicable law before deciding whether a modification is appropriate.

Until a judge signs a new child support order, the existing amount remains legally enforceable. Parents should continue making payments as ordered unless and until the court approves a modification.

What Is the Three-Year Rule for Child Support in Texas?

Not every child support modification is based on a major life event. Texas law also allows parents to request a review when enough time has passed since the current order was entered.

If at least three years have passed since the order was established or last modified, and applying the current child support guidelines would change the monthly amount by at least 20% or $100, the court may modify child support even if there has not been another material and substantial change.

As an example, a Houston parent may have received regular raises over several years while the child support order remained unchanged. If recalculating support under the current guidelines results in a qualifying difference, the court may consider modifying the order under the three-year rule.

The three-year rule does not automatically result in a modification. The court may still consider the circumstances surrounding the existing order before deciding whether a change is appropriate.

What Qualifies as a Material and Substantial Change for Child Support?

When a parent relies on a material and substantial change rather than the three-year rule, the Harris County Family Courts evaluate what has changed since the last support order was entered. Common examples include:

• A significant increase or decrease in either parent’s income
• Job loss, a layoff, or a career change
• A serious illness, injury, or disability
• A meaningful change in the possession and access schedule
• A child developing new medical, therapeutic, or educational needs
• A parent becoming legally responsible for additional children
• A substantial change in health insurance or childcare costs

One common example involves a Houston parent whose employer downsizes its workforce. After several months of searching, the parent accepts a new position that pays substantially less than their previous job. If the reduction in income is genuine and ongoing, the court may determine that a child support modification is appropriate.

Likewise, a child who develops ongoing medical needs after the original order was entered may require additional treatment, therapy, or specialized care that significantly increases monthly expenses. Those added costs may also support a request to modify child support.

What Evidence Is Needed to Modify Child Support?

Whether you are requesting an increase or a decrease in child support, the court expects evidence showing why the existing order should be changed. Providing complete and accurate financial information helps the court determine whether a modification is appropriate under Texas law.

Depending on your circumstances, helpful documentation may include:

• Recent pay stubs
• Federal income tax returns and W-2 forms
• Proof of bonuses, commissions, or self-employment income
• Documentation showing a job loss or reduction in hours
• Health insurance premium information
• Childcare invoices or receipts
• Medical bills or records showing increased healthcare expenses for the child
• Documentation of disability benefits or other changes affecting income

For instance, a Houston parent who recently changed jobs should be prepared to provide documentation showing both their previous earnings and their current income. Similarly, a parent requesting additional support because a child now requires ongoing therapy or specialized medical care should gather records showing how those expenses have changed since the original order was entered.

Providing organized, up-to-date documentation allows the court to evaluate your request based on current financial circumstances rather than estimates or assumptions.

How Is Houston Child Support Calculated?

Texas calculates child support using statutory guidelines based primarily on the paying parent’s monthly net resources. Net resources include income from most sources after certain allowable deductions, including taxes and the cost of the child’s health insurance.

For one family, this calculation may be straightforward because the parent earns a regular salary. For another, the court may need to evaluate commissions, bonuses, self-employment income, or other sources of earnings before determining the appropriate amount of support.

The guideline percentages are:

• 1 child: 20% of net resources
• 2 children: 25%
• 3 children: 30%
• 4 children: 35%
• 5 children: 40%
• 6 or more children: Not less than 40%

These guidelines apply to monthly net resources up to the statutory cap, which Texas periodically adjusts. If a parent’s income exceeds that amount, the court may consider the child’s proven needs when determining whether additional support is appropriate.

The court may also order medical support and dental support and, in some circumstances, deviate from the guideline amount when the facts of the case justify a different result.

What Do the Harris County Family Courts Consider When Deciding a Child Support Modification?

Meeting the legal requirements to request a modification does not automatically mean the court will change your child support order. The judge must review the evidence and determine whether modifying support is appropriate under Texas law.

Although every case is different, the Harris County Family Courts commonly consider factors such as:

• Each parent’s current income and financial resources
• Whether either parent’s financial circumstances have changed since the existing order was entered
• The child’s current financial needs, including medical, educational, and childcare expenses
• The amount of parenting time each parent exercises, when relevant
• Health insurance and medical support obligations
• Whether the requested modification is supported by reliable financial documentation

Consider a Houston parent whose income has increased substantially over the past several years while the child’s educational and extracurricular expenses have also grown. The court may review updated financial records from both parents to determine whether the existing child support order still reflects the child’s current needs and the parents’ financial circumstances.

Every modification request is decided on its own facts. Providing complete financial records and documentation allows the court to evaluate the request using current information rather than relying on outdated figures or estimates.

How Do You Modify Child Support in Houston?

Although every case is different, most child support modifications follow the same general process.

What Happens If Child Support Is Not Paid?

A child support order remains legally enforceable until the court changes it. Missing payments or paying less than the ordered amount can result in significant legal consequences.

Depending on the circumstances, enforcement actions may include:

• Wage withholding
• Interception of tax refunds
• Suspension of a driver’s or professional license
• Liens against certain property
• Passport denial
• Contempt of court, including fines or jail time

A parent who experiences a sudden loss of income should not simply stop making payments. For example, a Houston parent who loses a job may still owe the full amount of child support until the court signs a modified order. Filing a request for modification as soon as possible may help prevent additional arrears from accumulating.

Can Parents Agree to Modify Child Support?

Yes. Parents may agree that child support should be increased, reduced, or adjusted to reflect their current financial circumstances. An agreed modification often resolves the issue more quickly than a contested court proceeding.

However, an agreement between parents does not automatically change a child support order. The new amount must be included in a written modification order and approved by the court before it becomes legally enforceable.

This situation commonly arises when a parent’s income changes because of a new job or when both parents recognize that the child’s financial needs have changed over time. Even if both parents have been following a different payment arrangement, the original child support order remains enforceable until a judge signs the modified order.

Until that happens, the existing child support obligation continues to apply, and unpaid amounts may still accrue as arrears.

Frequently Asked Questions About Child Support Modifications in Houston

Can child support be lowered if I lose my job?

Possibly. A genuine job loss, layoff, or significant reduction in income may justify a child support modification. However, the existing support order remains in effect until the court signs a new one. If you lose your job, it is important to request a modification as soon as possible rather than simply reducing or stopping payments.

Does my new spouse’s income affect child support in Houston?

Generally, no. A new spouse’s income is not included when calculating your child support obligation. However, if you become legally responsible for additional children, that circumstance may affect the child support calculation under Texas law.

Can parents agree to change child support without going to court?

Parents may agree to change child support, but the agreement does not become legally enforceable until it is approved by the court. Until a judge signs a modified order, the existing child support obligation remains in effect.

When does child support end in Texas?

In most cases, child support continues until the child turns 18 or graduates from high school, whichever occurs later. If a child has a disability requiring ongoing care, the court may order support to continue beyond adulthood.
