You have a court order. Maybe it was entered years ago. Maybe circumstances have changed dramatically since then — a new job, a move, a change in the child’s needs, a parent who has stopped following the order entirely. You know things need to change. But how do you make that happen?
In Texas, the answer is a modification suit. And the gateway to getting one granted is understanding a critical legal standard: material and substantial change in circumstances.
What Is a Modification?
A modification is a lawsuit filed to change an existing court order. You can seek to modify custody arrangements (conservatorship and possession), child support, or other provisions of your current order. It’s not just a request — it’s a new legal proceeding that requires you to meet a specific threshold before a court will even consider changing what’s already been ordered.
That threshold is the material and substantial change standard.
What “Material and Substantial Change” Actually Means
Texas Family Code Section 156.101 requires that before a court modifies a conservatorship order, the party requesting the change must show that the circumstances of the child, a conservator, or another party have materially and substantially changed since the date of the prior order.
Let’s break that down.
“Material” means the change is significant — not trivial, not minor, not just inconvenient. The change has to actually matter to the child’s life or welfare.
“Substantial” means the change is real and meaningful in degree. Courts aren’t looking for small fluctuations in circumstance. They want to see that something has genuinely and significantly shifted.
Together, these words create a high bar — deliberately so. Courts don’t want families cycling in and out of litigation every time life gets a little bumpy. The standard is designed to require a real, significant reason before reopening a custody arrangement.
What Qualifies as a Material and Substantial Change?
There’s no exhaustive list, but here are circumstances Texas courts have recognized:
- Relocation — a parent moving a significant distance away, especially if it disrupts the existing possession schedule
- Remarriage or new relationship — particularly if the new partner presents safety concerns for the child
- Significant change in income — affecting child support calculations substantially
- Change in the child’s needs — new medical diagnosis, educational needs, mental health issues requiring different care
- Parent’s job change or schedule change — making the existing order unworkable
- Domestic violence or abuse — occurring after the prior order was entered
- Substance abuse issues developing after the order
- The child’s own expressed preference — particularly as the child gets older
- One parent consistently violating the existing order
What does not qualify: general dissatisfaction with the order, minor disagreements about parenting choices, or the fact that you think you could do better. The standard requires a genuine change in circumstances — not just a change of heart.
The Two-Step Process
Courts essentially run a two-step analysis in modification cases:
- Has there been a material and substantial change? If the answer is no, the case ends there. The court won’t even consider whether a different arrangement might be better.
- If yes — is modification in the best interest of the child? This is where the Holley factors come in again. Even if you prove a change in circumstances, you still have to show that the modification you’re seeking actually serves your child’s best interest.
Both steps require evidence. Both require preparation. And both are winnable with the right approach.
Don’t File Prematurely
One of the most common mistakes I see is people filing for modification before they’ve built their case. They’re frustrated, things have changed, and they want relief now. But a modification filed without solid evidence of a material and substantial change can be dismissed — and worse, it can tip off the other side to strengthen their position before you’re ready.
Before you file, make sure you can clearly articulate the change, document it, and connect it to the best interest of your child. If you’re not sure whether what’s happened rises to the level required, let’s talk it through.
