Texas Custody, Support & Visitation Modifications
Life changes. Jobs end. Parents move. Children grow up. When the order you have no longer matches the life you’re living, Texas law lets you modify it – but only if you meet a specific legal standard. We help Houston parents do it correctly.
What Is a Modification in Texas Family Law?
A modification is a formal court request to change an existing family law order. The most commonly modified orders are:
- Conservatorship – who has decision-making rights, including the right to designate the primary residence
- Possession and access – the visitation schedule
- Child support – the amount, who pays, or who provides health insurance
- Geographic restriction – where the custodial parent can live
A modification is not an appeal. It’s a new lawsuit asking the court to update its prior order because something significant has changed.
The Modification Standard in Texas
To modify a custody (conservatorship or possession) order, you must prove:
- A material and substantial change in the circumstances of the child, a parent, or another party affected by the order, since the date of the order; AND
- The modification is in the best interest of the child.
Examples of changes Texas courts have found “material and substantial”:
- A parent’s job loss, promotion, or relocation
- Remarriage or a new partner in the household
- A change in the child’s needs (medical, educational)
- New evidence of unsafe behavior by the other parent
- A child’s age and developmental needs shifting
- Incarceration or substance abuse by a parent
- The custodial parent denying the other parent’s possession or access
For child support modifications, the standard is a little different – see below.
Modifying a Texas Child Support Order
Texas allows child support to be modified when either:
- It has been 3+ years since the last order AND the calculated guideline support would differ by 20% or $100/month, OR
- There has been a material and substantial change in the circumstances of the child or a person affected by the order.
Common triggers:
- A change in the obligor’s income (up or down)
- A change in the children’s living arrangements
- Health insurance costs changing
- New children for whom the obligor has a legal duty of support

The "Within 12 Months" Trap
If you ask the court to change the parent with the exclusive right to designate the child’s primary residence within 12 months of the prior order, Texas imposes an affidavit requirement – you must file a supporting affidavit alleging:
- The child’s environment may endanger their physical health or significantly impair their emotional development;
- The parent currently designated has consented to the change and a change is positive for the child; or
- The parent has voluntarily relinquished primary care and possession for 6+ months and the change would be in the child’s best interest.
Without a sufficient affidavit, the court won’t even hold a hearing. This rule exists to prevent parents from re-litigating custody every few months.
Modifying the Possession Schedule
Possession orders are modified when the existing schedule no longer works because:
- A parent’s work schedule has changed
- The child is in a new school or activity schedule
- One parent has moved (and the order doesn’t account for it)
- The child’s needs have changed as they’ve aged
Many possession modifications are resolved by agreement – the parents and lawyers draft a new schedule and present it to the court for approval. Contested possession modifications are tried like any custody case, applying the best interest standard.
Modifying a Geographic Restriction
If your order says the primary residence must remain in a defined area (e.g., Harris County and contiguous counties), and you want to move further – or you want to prevent your co-parent’s move – you need to modify (or enforce) the geographic restriction.
Relocation cases are among the most heavily litigated in family law. Courts weigh:
- The reason for the move (new job, family support, lower cost of living)
- The effect on the non-moving parent’s relationship
- The age and adjustment of the child
- Whether a modified possession schedule can preserve meaningful contact
Plan early. Don’t move first and litigate later.
Modification or Enforcement - Which Do I Need?
People often confuse the two:
- Modification = changing the order going forward because circumstances have changed
- Enforcement = holding the other party in contempt for violating the existing order
If your co-parent is *violating* the current order (refusing visits, not paying support), that’s an enforcement action (see Enforcements). If the current order no longer fits your life, that’s a modification.
You can sometimes file both at once – but the legal frameworks are very different.

How long does a custody modification take in Texas?
Uncontested modifications can be finalized in 2–4 months. Contested modifications with a hearing or trial typically take 6–12 months.
Can I modify a Texas order without going to court?
You and the other parent can agree to a modification, but it isn't legally binding until a Texas court signs an order. Informal agreements offer no protection if the other party later changes their mind.
What if my ex won't agree to modify child support?
File a modification suit. If you meet the statutory threshold (3 years + 20%/$100 difference, or a material and substantial change), the court can order a new amount regardless of whether the other parent agrees.
Can the other parent prevent me from moving?
Possibly - if the order has a geographic restriction. You may need to file a modification to lift or change the restriction before moving, particularly if you have the primary residence designation.
Does a job loss automatically reduce my child support?
No. Child support doesn't change until a new order is entered. If you've lost your job, file a modification immediately - your obligation continues to accrue at the prior rate until the new order is signed.
