Life changes. Jobs disappear. Incomes shift. Children grow, and their needs evolve. When the child support order you are living under no longer reflects reality, Texas law gives you a path to change it - but only if you follow the right process.

Key Takeaways

• In Texas, you can usually modify child support if there has been a material and substantial change in circumstances or if the order is at least three years old and the guideline amount would differ by 20% or $100 from the current order.

• Parents must keep paying under the current order until a judge signs a new child support order. Informal agreements between parents do not legally change child support obligations and will not protect you in court.

• Lopez Lawyers handles child support modification cases across Texas with a primary focus on Dallas–Fort Worth and San Antonio. Call (469) 399-0469 or message us online for assistance with your case.

• A material change in circumstances can justify modifying support. Concrete examples include income changes, job loss, a new child for the obligor, changes in where the child lives, serious medical needs, or incarceration for at least 180 days.

• A Texas child support modification lawyer can calculate guideline support, negotiate with the other parent or the attorney general, gather evidence, and present the modification case in court - protecting both your finances and your child's well-being.

Texas Child Support Modification: How Lopez Lawyers Can Help You Now

If you are a parent in Dallas–Fort Worth or San Antonio whose existing child support order no longer fits your reality - maybe you lost a job in 2025, received a significant promotion, or your child develops serious medical needs that did not exist when the order was signed - you are not stuck. Texas law allows you to seek a court-ordered change.

A child support modification is not a private handshake deal. It is a formal adjustment to an existing child support order, entered by a judge, that replaces the old obligation with one that reflects current circumstances. Until a judge signs that new order, the old one controls.

Lopez Lawyers, led by David Lopez, focuses exclusively on divorce, child custody, property division, and child support. The firm regularly handles modification cases in Dallas County, Tarrant County, Collin County, Denton County, Bexar County, and surrounding areas throughout Texas.

If you are worried about overpaying, not receiving enough, or falling behind on child support payments, do not wait. Call (469) 399-0469 for a confidential child support modification review, or message us online any time - day or night. We will explain your options in plain English, evaluate whether you meet the legal standard for a modification, and outline a plan before you make any decisions.

When Can You Modify a Child Support Order in Texas?

Texas courts follow specific rules under Texas Family Code Chapter 156 for changing an existing child support order. You cannot simply decide to pay a different amount or file a petition without meeting one of two legal standards.

Two primary pathways to modify child support in Texas:

1. Material and substantial change in circumstances. You must show that the circumstances of the child, the paying parent (obligor), or the receiving parent (obligee) have materially changed since the date the current order was rendered or the date a mediated settlement agreement was signed.

2. The three-year / 20% or $100 rule. A court can modify child support every three years if conditions change and the monthly guideline amount would differ from the current order by at least 20% or $100. Texas allows modifications every three years under this rule without requiring proof of any other changed circumstances - as long as the order was based on guideline support.

Both the parent who pays and the parent who receives support can file to modify. The Texas Attorney General's Child Support Division can also initiate modifications in certain child support cases it manages.

These standards apply statewide - whether you are in a Dallas family court or a Bexar County courtroom. Child support can be modified due to changed circumstances, but agreeing with the other parent is helpful though not enough on its own. A judge must still sign a new order before anything becomes legally enforceable.

Understanding "Material and Substantial Change" in Texas Child Support Law

Texas law does not give a precise definition of material and substantial change. Instead, judges look at the specific facts of each case to decide whether the change is real, important, and ongoing - not just a short-term fluctuation.

Typical scenarios that often qualify:

• Income changes. A significant increase or decrease in either parent's income - such as a layoff, a major raise, or a shift to commission-based pay. A parent's income increase or decrease can necessitate support changes.

• New children. A new child for the obligor in a different household can justify a modification request, because guideline calculations account for other children.

• Medical or special needs. Changes in the child's medical needs may require support adjustments - for example, a new diagnosis requiring ongoing therapy or specialized education.

• Living arrangements. A change in where the child lives or which parent has primary custody or possession can shift who should pay child support.

• Incarceration. Incarceration for at least 180 days is a valid reason for modification, provided the incarceration is not for failure to pay child support or for family violence.

A material change in circumstances must be proven for modification. Changes must be shown to justify modifying child support amounts - the petitioner carries the burden of proof.

Lopez Lawyers helps parents gather pay records, medical bills, school records, and other evidence to prove a material and substantial change in both agreed and contested modification cases.

If you have had a major life shift in the last 6–12 months, call (469) 399-0469 or send us a message online to see if your change is likely to qualify.

How Texas Courts Calculate Child Support (and What Changes on Modification)

Texas uses child support guidelines based on the paying parent's net monthly resources and the number of children being supported. Child support is calculated based on the obligor's net monthly resources, and child support payments depend on the number of children supported.

How "net resources" are calculated:

• Start with gross income from all sources (wages, overtime, bonuses, self-employment income, etc.)

• Subtract Social Security taxes, federal income tax (assuming a single filer with the standard deduction and one personal exemption), union dues or mandatory retirement contributions, and health insurance costs for the child

Guideline percentages:

Number of Children	Percentage of Net Resources
1 child	20%
2 children	25%
3 children	30%
4 children	35%
5 children	40%
6+ children	Not less than 40%

These percentages apply only up to the statutory net-resources cap. The maximum income considered for child support was previously $8,550 monthly under earlier caps, but effective September 1, 2025, the cap increased to $11,700 per month. Above that cap, a judge may order additional support based on the child's proven needs. Texas child support guidelines adjust every six years for inflation, which is why the cap changes over time.

In a modification case, the court re-applies these guidelines to new financial information. The judge may also consider factors under Texas Family Code § 154.123 - such as travel costs for long-distance visitation, special needs, or very high or very low incomes - to decide whether to deviate from the guidelines.

Lopez Lawyers regularly runs guideline calculations for parents in Dallas, Fort Worth, Plano, Frisco, San Antonio, New Braunfels, and nearby communities. We can explain what a realistic adjusted support amount might look like before you file.

Common Reasons Parents Seek to Modify Child Support

Most parents do not ask to modify child support lightly. A significant life change qualifies for a child support modification, and these requests usually follow real shifts in work, health, or the child's daily life.

The most common reasons for modification include:

• Job loss, reduced hours, or a major income drop making the current child support obligation unmanageable

• Promotion, new job, or business success suggesting support should increase to reflect current income

• A parent's move that significantly affects possession schedules and travel expenses

• A child developing serious medical conditions, mental-health needs, or special-education requirements that cost money the original order did not anticipate

• The paying parent becoming responsible for additional children in another household

• The child now primarily living with the other parent or a different caregiver than when the order was signed

Whether one parent seeks to lower support or the other seeks to raise it, the same legal standards apply. The evidence may look different - pay stubs and termination letters for a decrease versus proof of the other parent's higher earnings for an increase - but both sides must meet the burden of showing that circumstances have materially changed.

Agreed vs. Contested Child Support Modifications

An agreed (uncontested) modification means both of the child's parents accept the new child support amount and terms. They present an agreed order for the judge to sign. This is generally the fastest path.

A contested modification happens when parents disagree - over whether a change is warranted, how big the change should be, or what the correct guideline amount really is (for example, disputes about income, bonuses, or self-employment earnings from a person's business).

How Lopez Lawyers approaches agreed modifications:

• Drafting accurate paperwork that complies with the Texas Family Code and local Dallas or Bexar County rules

• Coordinating signatures and submission to minimize court appearances where allowed

• Reducing errors that might delay the judge's approval

Our strategy for contested modifications:

• Gathering evidence - pay records, tax returns, medical records, child-care invoices

• Negotiating with the other parent, their lawyer, or the Attorney General's office

• Preparing for hearings and, if necessary, a full evidentiary trial on the modification request

Even in agreed cases, the judge must still find that the new amount is in the child's best interest before signing the order. A lawyer can assist in gathering evidence and filing necessary documents for modification in either scenario.

Why You Still Must Follow the Current Order Until It's Changed

Under Texas law, you must obey your existing child support order until a judge signs a new one - even after you file to modify. Modifying a child support order in Texas requires a formal legal process, and nothing changes until that process concludes.

Informal "handshake" agreements - such as agreeing to pay less for a few months while you look for a new job - are not enforceable. If the other parent later asks the court system to enforce the original amount, you will owe every dollar the old court order required.

Potential consequences of unilaterally reducing or stopping payments:

• Accumulating arrears that cannot be erased retroactively by a modification

• Wage garnishment, liens on property, and interception of tax refunds

• Suspension of driver's, professional, or recreational licenses

• Possible contempt of court, including fines and even jail time in serious cases

If you truly cannot pay the ordered certain amount, act quickly. Consult a lawyer, gather proof of your changed circumstances, and file a prompt modification request instead of simply stopping payment. The court generally cannot lower support retroactively for months before a modification was filed.

If you are falling behind or anticipate missing a payment, call (469) 399-0469 or contact Lopez Lawyers online before the problem escalates.

Special Situations: When the Child's Living Situation or Caregiver Changes

Changes in where the child lives or who provides day-to-day care can strongly affect both child support and custody orders. These situations deserve careful analysis because they may shift the entire support dynamic.

Scenarios that frequently arise:

• The child begins living primarily with the parent who used to pay support, effectively reversing who should receive money

• The child moves to live with a grandparent or other relative for at least six months, raising questions about standing and support obligations

• The child relocates to a new county - for example, from Dallas County to Bexar County - or out of state, triggering possible venue or jurisdiction questions

In some situations, a nonparent (like a grandparent, aunt, or older sibling) who has had care, control, and possession of the child for a sufficient period may have standing to seek changes to custody or support orders under Texas Family Code Chapter 102.

These shifts can lead to a complete change in who pays and who receives child support, along with new visitation and possession schedules that affect travel costs and support calculations.

Lopez Lawyers can evaluate standing and strategy for relatives or new caregivers and can coordinate child custody modification and child support modification in a single, coherent plan.

Working with or Without the Texas Attorney General on Modifications

The Texas Attorney General Child Support Division (OAG) plays a significant role in child support cases across Texas - establishing, modifying, and enforcing orders, especially when one parent receives state services. The Texas Office of the Attorney General can facilitate modifications through the Child Support Review Process (CSRP).

Key differences between relying solely on the OAG and hiring private counsel like Lopez Lawyers:

	OAG	Private Counsel (Lopez Lawyers)
Represents	The State of Texas - not either parent	You, the individual parent
Caseload	Large volume; limited individualized attention	Focused on your specific goals and finances
Strategy	Applies guidelines broadly	Tailors approach to your custody, income, and long-term plan
Availability	Government schedule and process	Direct attorney access

Parents can have both: the OAG may be involved in the case while a parent is still represented by Lopez Lawyers to advocate for their interests in hearings and negotiations.

The typical OAG modification process involves administrative reviews, a notice of proposed order, and - if the party cannot reach an agreement - a court hearing. An experienced lawyer can help parents prepare documentation and appear at local child support courts in Dallas or San Antonio.

If you received an OAG notice about modifying child support, immediately call (469) 399-0469 or send us a message online to avoid signing an order you do not fully understand.

The Child Support Modification Process with Lopez Lawyers

Lopez Lawyers uses a structured process to keep modification cases focused and efficient while protecting the client's long-term interests. Here is what you can generally expect:

Step 1 - Initial strategy consultation. We review your current order, recent financial and life changes, and realistic outcomes under Texas child support guidelines. This consultation helps you decide whether to file and what to request.

Step 2 - Investigation and documentation. We collect pay stubs, tax returns, medical bills, child-care receipts, and proof of any new children or changes in living arrangements. A lawyer can assist in gathering evidence and filing necessary documents for modification - and thoroughness at this stage matters.

Step 3 - Negotiation and mediation. Where appropriate, we attempt to reach an agreed modification that the court can approve, often saving time and money.

Step 4 - Court hearings. If the case is contested, we prepare testimony, exhibits, and arguments to show a material and substantial change and why the proposed order is in the child's best interest.

Step 5 - Final orders and implementation. We ensure the signed order is filed correctly and explain what you need to do going forward - such as adjusting employer withholding or updating the form of payment.

Throughout the process, we keep clients informed at each stage with a practical, no-nonsense explanation of timelines and what to expect in the same court that has jurisdiction over your case.

Cost, Timing, and What to Expect Financially

Many parents hesitate to contact a lawyer because they worry about cost while already struggling with child support payments. That concern is understandable - but waiting often makes things worse.

Factors that affect the cost of a child support modification case:

• Whether the case is agreed vs. contested

• Complexity of income issues (self-employment, multiple jobs, bonuses, or high-asset situations)

• Whether child custody or visitation is also being modified at the same time

• The responsiveness of the other party and the schedule of the court

General expectations on timing:

• Agreed modifications can sometimes be completed in weeks, depending on court availability

• Contested modifications can take several months or longer, particularly in crowded urban dockets like Dallas County and Bexar County

• Many modification cases can take at least six months to process, depending on complexity and document delays

Lopez Lawyers will discuss fee structures and expected ranges up front. We may suggest cost-saving strategies such as narrowing the issues, gathering documents efficiently, and pursuing negotiation or mediation where appropriate.

How Child Support Modification Interacts with Custody and Visitation

Child support, child custody (conservatorship), and visitation (possession and access) are related but legally distinct issues under Texas law. A change in one can trigger or justify a change in another.

How custody or visitation changes affect support:

• A shift in primary custody from one parent to the other typically changes who should pay child support

• A significant change in overnights or extended possession time can alter the support calculation

• Long-distance moves that affect travel costs and parenting schedules may justify a deviation from standard guidelines

Parents sometimes seek a combined modification - adjusting both custody orders and support at the same time - to create a coherent plan for where the child lives and how expenses are covered. Lopez Lawyers handles all four of David Lopez's core practice areas - divorce, child custody, property division, and child support - so the firm can align support changes with broader family-law strategy.

Texas courts will still evaluate child support under the guidelines, but they may consider new parenting-time arrangements in deciding whether a guideline or non-guideline support amount is in the child's best interest.

Frequently Asked Questions About Child Support Modification in Texas

Below are answers to practical questions that Texas parents frequently ask about the modification process. Each is answered in straightforward language to help you determine your next steps.

How often can I ask the court to modify my Texas child support order?

There is no strict limit on how many times a parent can request a modification. However, each request must meet either the material and substantial change standard or the three-year / 20% or $100 rule. Simply being unhappy with the amount is not enough.

Repeatedly filing weak or frivolous modification cases can frustrate judges and potentially result in an award of attorney's fees against the person who filed. Courts expect the petitioner to present real evidence of changed circumstances - not speculation or a desire for a different outcome.

Before refiling, consult with Lopez Lawyers to evaluate whether your circumstances have changed enough since the last order or last modification attempt to justify a new request.

Can I modify child support if my order is from another state but my child now lives in Texas?

Interstate child support cases are governed by federal and state rules like the Uniform Interstate Family Support Act (UIFSA), which determine which state has jurisdiction. Texas may or may not be able to modify an out-of-state support order, depending on where the child, both parents, and the original order are located.

Generally, if both parents and the child now live in Texas, the state can register and modify the foreign order. If one parent still lives in the original state, jurisdiction questions become more complex and require careful legal analysis.

Lopez Lawyers can review your order and living arrangements to determine the proper state and court for filing. Call (469) 399-0469 or contact us online with copies of your existing orders.

Will my child support automatically go down if I lose my job in Texas?

No. Child support does not automatically change when a parent loses a job. The current order remains in full effect until a judge signs a new one. Every payment you miss accrues as arrears.

Job loss can be a strong basis for a modification if it is genuine and not caused by intentional underemployment. But you must actively file a modification case and provide proof - termination letters, unemployment records, documented job search efforts. Courts look at whether the decrease in income is involuntary and whether you are making reasonable efforts to find new work.

Do not wait months hoping things will resolve. The court generally cannot retroactively lower support for the period before the modification was filed. If you recently lost your job, contact Lopez Lawyers quickly to discuss filing and strategies to minimize arrears.

Can we agree to a lower (or higher) amount than the Texas child support guidelines?

Texas allows parents to agree to a non-guideline child support amount, but the judge must find that the agreed amount is in the child's best interest before signing the order. You cannot simply write any number into an agreement and expect the court to approve it.

Non-guideline agreements can complicate future modifications. If the original order was based on an agreement that deviated from guidelines, you usually must prove a material and substantial change to modify it - you cannot simply rely on the three-year / 20% or $100 rule alone.

Lopez Lawyers can negotiate and document non-guideline agreements, explain the short- and long-term implications, and help you reflect on whether the proposed amount truly serves your child's needs before you sign.

Does Texas ever terminate child support completely before age 18?

Child support obligations end when the child turns 18 in Texas, or when the child graduates from high school - whichever comes later. In most cases, the obligation continues until at least one of those events occurs.

Limited situations may end support earlier: legal emancipation of the child, marriage of the child, or termination of the parent-child relationship. Each of these is a separate legal proceeding with strict requirements - they do not happen automatically.

Even if future support is terminated, past-due arrears generally remain collectible and cannot be erased except in unusual circumstances. Parents considering early termination or an end-of-support request should speak with Lopez Lawyers about the risks, alternatives like modification, and long-term impact on both parent and child.
