Understanding Texas Custody and Material and Substantial Change: Key Insights for Parents

Last week, a dad told us he felt like he was starring in his own reality show called “Life Happens.” One minute, he was cruising along—work was steady, weekends with his kids were predictable, and even co-parenting had settled into a rhythm. Then life threw in a new job across town, a remarriage, and a house full of boxes. Suddenly, the old custody order didn’t fit his new reality. That’s where Texas Custody and Material and Substantial Change steps in.

At its core, this legal standard is what Texas courts use to decide if a custody order needs a tune-up when circumstances shift in a big way. The quick takeaway? If your life looks very different from when the original order was signed—and those changes affect your child’s stability—the court may allow a modification.

In this article, you’ll learn what actually counts as a “material and substantial change,” how parents in Texas have successfully navigated these tricky waters, and why judges sometimes say yes (or no) to custody modifications. Along the way, we’ll share practical strategies you can use right now, from smoothing transitions at home to understanding the evidence courts look for. You’ll also hear how The Law Office of Bryan Fagan, PLLC helps families like yours protect what matters most: your child’s future.

Key Takeaways

  • A ‘material and substantial change’ in circumstances is required under Texas Family Code to modify custody orders, with documentation of significant changes being essential.
  • The legal process for modifying custody involves filing a petition, presenting evidence of the change, and may be classified as uncontested or contested based on parental agreement.
  • Prioritizing the child’s best interest is of utmost importance in custody decisions, guided by the Holley factors that assess the child’s emotional, physical needs, and overall welfare.

Defining “Material and Substantial Change” Under Texas Family Code

Under Texas Family Code Chapter 156, courts require proof of a material and substantial change in circumstances before modifying a custody order. This standard ensures that custody arrangements remain aligned with what serves the child’s best interest, rather than the convenience of either parent. A material and substantial change is not just a minor adjustment in family life—it must be significant, continuing, and directly tied to the child’s well-being. For a deeper exploration, see our resource on Texas Custody and Material and Substantial Change.

Documenting these changes thoroughly is essential when seeking a modification. Examples may include relocation that impacts school or visitation schedules, a substantial shift in a parent’s work hours, remarriage that alters household dynamics, or new medical or educational needs for the child. Courts look for credible evidence, such as employment records, school reports, or medical documentation, to determine whether the change rises to the level required under Texas law.

Because custody modifications directly impact a child’s stability, judges apply this standard carefully. The goal, consistent with Texas Family Code §153.002, is always the child’s best interest. Parents considering a modification should be prepared to show not only that life circumstances have changed, but also that altering the custody order will create a more stable, supportive, and nurturing environment for their child.

At the Law Office of Bryan Fagan, we guide families through this process with compassion and precision, ensuring that parents understand both the legal standards and the emotional realities at play.

Examples of Material and Substantial Change in Texas Custody Cases

Understanding what qualifies as a material and substantial change is critical when seeking to modify a custody order in Texas. Courts rely on this standard, found in Texas Family Code Chapter 156, to determine whether circumstances have shifted enough to justify a modification. A Texas Custody and Material and Substantial Change case must demonstrate not just temporary or minor adjustments in family life, but significant and lasting changes that directly affect the child’s best interests. For a deeper explanation, you can review our article, Does Your Custody Order Need to Be Modified?.

Common examples of qualifying changes include a parent’s relocation or repeated moves, which may disrupt the child’s stability and lead the court to impose geographic restrictions. A new residence that substantially increases the cost of travel for visitation can also meet this standard. Likewise, substantial changes in a parent’s employment—such as working overnight shifts, taking a job that requires frequent travel, or losing employment altogether—may qualify if they reduce the parent’s ability to provide consistent care.

Child safety is another central concern for Texas courts. Under Texas Family Code §153.002, the child’s best interest is the primary consideration in any custody determination. Evidence of family violence, abuse, neglect, or unsafe living conditions can weigh heavily in favor of modifying an existing order. Courts take these matters seriously, often acting swiftly to ensure a child is not exposed to dangerous environments.

Beyond safety, the child’s evolving needs also carry significant weight. For example, the onset of a medical condition requiring specialized care, behavioral or developmental concerns, or even academic struggles may warrant a custody change. Household changes, such as remarriage or the introduction of new siblings, can shift family dynamics enough to justify a modification, particularly if these changes affect the child’s emotional well-being or daily routine.

Each of these circumstances demonstrates how broad the concept of a material and substantial change can be, yet how carefully courts apply it to protect children. If you are considering whether your family’s situation qualifies, it’s important to seek guidance from an experienced attorney. The team at the Law Office of Bryan Fagan can help you evaluate your options, gather the right documentation, and present a strong case that prioritizes your child’s needs.

The legal process for modifying custody orders in Texas involves:

  • Filing a petition with the court clerk’s office.
  • Outlining the reasons for the requested modification in the petition.
  • Providing evidence of a material and substantial change.
  • Recognizing that both parents have the right to file for custody or visitation modifications.

Once the petition is filed, all parties listed in the current custody order must be notified of the proceedings. The modification request can be classified as uncontested if both parents agree on the changes or contested if there are disagreements. If the other parent does not respond or agree, the case becomes contested and requires a court hearing.

In cases where both parents agree on the proposed changes, an agreement must be drafted for the judge to sign. This agreement, once signed by the judge, must be filed to finalize the child custody orders modifying child custody orders. The court order has the authority to uphold, modify, or terminate the existing custody arrangement based on the evidence presented.

Providing valid reasons and credible evidence for the requested modification is crucial throughout this process. Whether the case is uncontested or contested, the final decision rests with the court, which the court considers will always prioritize the child’s best interests. In some cases, deferred adjudication may be an option.

Best Interest of the Child Standard

In any custody matter, Texas courts are guided by one unshakable principle: the child’s best interest. Under Texas Family Code §153.002, this standard ensures that custody decisions place the child’s safety, stability, and overall development above all else. When families face a Texas Custody and Material and Substantial Change, the court carefully evaluates whether a modification will truly enhance the child’s well-being. For a deeper look at how courts approach modifications, see our article, Texas Child Custody Order Modification: What You Need to Know.

Judges use the well-established Holley factors—first recognized by the Texas Supreme Court—to guide these decisions. These factors include the child’s wishes, their emotional and physical needs, potential dangers, each parent’s abilities, the stability of each home, and the parent’s capacity to support the child’s future. Courts may also weigh issues such as parental alienation, negative comments about the other parent, and the importance of maintaining sibling bonds.

Because life is always changing, courts remain flexible. The addition of a stepparent, the arrival of new siblings, or shifts in household routines can influence a child’s needs. Similarly, evolving circumstances—such as a child requiring additional emotional support or academic stability—can justify a custody modification. The goal is not simply to change an order for the sake of change, but to ensure that custody arrangements nurture the child’s emotional, physical, and psychological health.

Families navigating these issues often feel overwhelmed by the complexity of Texas law. That’s where the compassionate guidance of attorneys at the Law Office of Bryan Fagan makes a difference. Our team helps parents understand how courts evaluate best-interest factors, gather the right evidence, and present a compelling case.

Checklist for Parents Considering Custody Modification

Parents considering a custody modification in Texas should begin with a thoughtful and well-documented plan. Under Texas Family Code Chapter 156, a modification requires proof of a material and substantial change in circumstances that directly impacts the child’s best interest. Understanding what qualifies as such a change—and preparing the right evidence—is essential to presenting a strong case. For a deeper dive into this topic, see our article, Does Your Custody Order Need to Be Modified?.

Open and respectful communication with the other parent can often reduce conflict and may even result in agreed modifications, which are typically faster and less stressful than contested cases. However, when disagreements remain, careful documentation becomes critical. Parents should collect records such as employment changes that affect parenting time, medical reports demonstrating a child’s evolving health needs, school or daycare notes highlighting behavioral or academic concerns, and, when applicable, police reports or other official records that relate to safety issues.

It is also wise to keep track of changes in the child’s living environment or routines. Even small details—like changes in after-school care or challenges in transportation arrangements—can become important when courts consider whether the existing order still serves the child’s best interest. Courts give significant weight to consistency and stability, as reflected in Texas Family Code §153.002, which states that the best interest of the child is the primary consideration in custody matters.

Parents should avoid relying on informal, “handshake” agreements without court approval, since these are not enforceable and may complicate matters later. Acting promptly when significant changes arise not only helps protect the child but also prevents long-term disputes from escalating.

Working with a knowledgeable Texas family law attorney can provide clarity and peace of mind during this process. The attorneys at the Law Office of Bryan Fagan regularly help parents navigate the complexities of Texas Custody and Material and Substantial Change, guiding them step by step to ensure the child’s needs remain front and center.

Common Mistakes Parents Make in Custody Modification Cases

Parents navigating custody modifications in Texas should be mindful of common pitfalls that can jeopardize their case. Under Texas Family Code Chapter 156, courts will only grant a modification when there is clear and convincing evidence of a material and substantial change that directly impacts the child’s best interest. One of the most frequent mistakes parents make is failing to present sufficient proof of this change. Without compelling documentation—such as employment records, school reports, medical records, or testimony—courts are unlikely to approve a modification. For further guidance, review our article, How to Petition for a Modification After a Change of Circumstances in Texas Family Law.

Another critical error is overlooking the importance of the child’s best interests. Courts apply the standard found in Texas Family Code §153.002, which makes the child’s emotional, physical, and psychological well-being the primary concern. A modification request that centers on the parent’s convenience rather than the child’s stability will rarely succeed. Parents should focus their case on how the change will improve the child’s daily life, school performance, or overall safety.

Poor communication with the other parent is also a recurring problem. Constant conflict or failure to cooperate can disrupt the child’s routine and paint a negative picture in court. Judges often look favorably on parents who demonstrate a willingness to co-parent respectfully, even in difficult circumstances.

Social media is another overlooked hazard. Posts that disparage the other parent, showcase irresponsible behavior, or reveal inconsistencies can easily be introduced as evidence. Parents should exercise extreme caution online during a pending custody case.

Finally, waiting too long to act can have serious consequences. If a substantial change has occurred—such as a relocation, job loss, or a child’s new health needs—delaying a petition can undermine credibility and weaken the case. Acting promptly and with proper legal guidance gives parents the best chance of success.

Client Success Stories

Client success stories illustrate the profound impact of effective custody modifications.

Navigating custody modifications effectively requires access to a range of resources.

Frequently Asked Questions

Can custody agreements be changed in Texas?

Yes. Custody orders in Texas (legally called conservatorship, possession, and access orders) can be modified if there has been a material and substantial change in circumstances and the change is in the child’s best interest. Parents can agree on modifications, or the court will decide if they disagree.

What constitutes a material change in circumstances regarding custody?

A material change can include a parent’s relocation, a new work schedule, remarriage, unsafe conditions, family violence, or significant changes in a child’s needs such as health or schooling. The change must be substantial, not temporary, and directly tied to the child’s stability and best interests.

What is the biggest mistake in a custody battle?

One of the biggest mistakes is focusing on attacking the other parent instead of proving how your plan serves the child’s best interest. Courts look for stability, cooperation, and credible evidence—like school records, medical notes, or calendars—not just accusations.

How to modify a custody agreement?

To request a modification, you must file a petition in the court that issued the original order. The petition explains the changes in circumstances and why the modification is in the child’s best interest. The other parent is served and may agree, or if they contest, the case can proceed through mediation or a hearing.

Can a child decide which parent to live with in Texas?

Not exactly. A child doesn’t get the final say, but children 12 or older may tell the judge their preference in chambers under Texas Family Code §153.009. The judge will consider the child’s wishes along with all other best-interest factors.

How far away can the custodial parent move in Texas?

It depends on the custody order. Many orders include a geographic restriction that limits how far the custodial parent can move—often within a specific county or nearby counties. To move farther, the parent usually needs court approval or the other parent’s agreement.

What qualifies as a change in circumstance?

Qualifying changes are substantial, lasting, and occurred after the original order. Examples include long-term job changes, relocation affecting parenting time, repeated violations of visitation schedules, or new health and safety issues affecting the child.

What are the requirements for a change of circumstances?

You must prove two things: (1) there has been a material and substantial change since the last order, and (2) modifying the order is in the child’s best interest. If you file within one year of the last order, stricter requirements apply—such as proving endangerment, voluntary relinquishment, or parental agreement.

What is interference with custody?

Interference happens when a parent or another person intentionally prevents or disrupts the other parent’s court-ordered time with the child. This could mean refusing exchanges, sabotaging visits, or manipulating schedules. Interference can lead to enforcement actions, fines, extra visitation, and in some cases, even a change in custody.
