School starts on August 12, 2026 at Conroe ISD — and for parents who need to change their custody order before the new academic year begins, the clock is already running. Whether you need to modify a geographic restriction so your child can enroll in a different school, adjust the possession schedule to align with a new work schedule, or update child support after a job change, the question is always the same: how long does this actually take in Montgomery County?
At Griffin & Cain, Attorneys at Law, we handle custody and support modifications in every Montgomery County family court. The realistic answer depends on whether your modification is agreed or contested — and whether you file today or next week.
The Realistic Timeline for Agreed Modifications
If both parents agree on the changes, the modification can move quickly. An agreed modification requires drafting the modification documents (your attorney does this), both parents signing the agreement, filing the documents with the court, and obtaining the judge's signature.
In Montgomery County, agreed modifications filed in the 284th, 410th, or 418th District Courts can typically be approved within 2–4 weeks after filing. Some judges will sign agreed orders on their regular submission day without requiring the parties to appear. Others want a brief prove-up hearing where one or both parents testify that the agreement is voluntary and in the child's best interest.
If you file an agreed modification by mid-July, you have a strong chance of having a signed order before August 12. But every day of delay compresses the window. Filing in the last week of July makes approval before school starts uncertain.
The Realistic Timeline for Contested Modifications
If the other parent opposes the modification, the timeline stretches dramatically. A contested modification requires filing a petition and serving the other parent with citation. There is a mandatory waiting period after service — the respondent typically has until the Monday following 20 days after service to file an answer. After the answer is filed, the court must set a hearing date on its docket. Montgomery County family courts typically have 60–90 day dockets for contested matters. Temporary orders may be available for immediate issues, but a full modification hearing takes months.
If you are filing a contested modification today — in late July — you should not expect a final hearing before August 12. What you can pursue, however, are temporary orders that address the most urgent issues while the modification case proceeds.
Using Temporary Orders to Bridge the Gap
Texas Family Code §156.006 allows the court to enter temporary orders during a pending modification. These orders can address temporary possession and access schedules pending the final hearing, temporary child support adjustments, temporary geographic restrictions or modifications, and temporary injunctions preventing either parent from taking specific actions (enrolling the child in a different school, relocating, etc.).
Temporary orders can be set more quickly than final hearings — sometimes within 2–3 weeks of filing. If your primary concern is ensuring your child is enrolled in the correct school by August 12, a temporary order can establish the school enrollment while the underlying modification case works through the full process.
Common Modifications That Need to Happen Before School Starts
Geographic restriction changes
If you need to move outside the geographic restriction in your order — from Conroe ISD to Magnolia ISD, for example — the modification must be approved before you enroll your child in the new district. Enrolling without court authorization puts you in contempt and gives the other parent grounds to seek an emergency order returning the child to the original school district.
Possession schedule adjustments
A new job, a shift change, or a relocation by one parent may require adjusting the weekday or weekend possession schedule. If your current order gives you Thursday overnights under the ESPO but your new work schedule makes Thursday pickup impossible, the schedule needs to change — ideally before school starts and the new routine kicks in.
Child support recalculations
If the other parent's income has changed, or if the new $11,700 child support cap affects your calculation, filing before the school year ensures the new support amount is in place when school expenses (supplies, activities, uniforms) begin.
Primary residence designation
If you and your co-parent agree that the child should change primary residences — moving from one parent's home to the other — the modification must be formalized before the child enrolls in the new school. School enrollment requires proof of residency, and the school district may require a copy of the court order designating the enrolling parent's home as the child's primary residence.
What Courts Look for in a Modification Request
To modify a custody order in Texas, you must demonstrate a material and substantial change in circumstances since the date of the current order. Courts consider changes in a parent's employment, income, or work schedule, changes in the child's needs (age, health, educational requirements), changes in a parent's living situation (new marriage, new partner, relocation), evidence that the current order is not working (frequent conflicts, denial of possession), and changes in law — such as the ESPO default or the updated child support cap — that create a new baseline for what the court would order today.
The change must also be in the child's best interest. This is the standard that governs every custody determination in Texas, and the court will evaluate the child's physical and emotional needs, the ability of each parent to meet those needs, the stability and suitability of each home environment, the child's ties to school and community, and the child's own preferences (if the child is 12 or older).
Don't Wait — File Now
If you need a custody modification before the 2026–2027 school year begins, every week you delay reduces the likelihood of having a signed order by August 12. Agreed modifications filed in mid-July can still be approved in time. Contested modifications filed now will likely require temporary orders to bridge the gap. And modifications that are not filed until August are too late for the start of school — full stop.
Call Griffin & Cain at (936) 441-2999 to discuss your modification. We can evaluate your grounds, advise whether an agreed or contested path is realistic, and file the necessary documents this week. We practice in every Montgomery County family court and can help you meet the school-year deadline.
