How to Modify Conservatorship or Possession in Texas

The Petition to Modify process, the material and substantial change standard, and what the court considers

When can you modify a Texas family court order?

You can ask a Texas court to modify a conservatorship, possession, or child support order if there has been a material and substantial change in circumstances since the order was signed (§ 156.101). The change must affect either the child or one of the parents — it must be real, significant, and not something that was anticipated when the original order was entered.

The two-year waiting period

Under § 156.101(a), if a final order was signed less than one year ago, you must file an affidavit with your Petition to Modify alleging one of the following:

  • The child's present environment may endanger the child's physical health or significantly impair the child's emotional development
  • The managing conservator has voluntarily relinquished primary care and possession of the child for at least six months
  • The child is 12 or older and expresses a preference

Wait at least one year

If your order is less than one year old and none of these exceptions apply, the court will likely dismiss your petition. Texas courts disfavor repeated modification suits that destabilize children's lives.

What counts as a material and substantial change?

Courts have found material and substantial changes in circumstances in situations including:

  • A parent relocating to another city, state, or country
  • A significant change in either parent's work schedule that affects the ability to exercise possession
  • A parent remarrying or cohabitating with someone who poses risks to the child
  • Documented substance abuse or domestic violence by a parent
  • The child developing special needs that the current order does not address
  • A parent's consistent violation of the possession order over an extended period
  • The child turning 12 and expressing a preference

The following are generally not sufficient on their own:

  • General disagreements about parenting style or decisions
  • A desire for a “better” schedule without changed circumstances
  • Minor or temporary difficulties in exercising the current order

How to file a Petition to Modify

  1. File in the original court — The district court that entered the original order retains jurisdiction unless the child and all parties have lived elsewhere for at least six months
  2. Complete the Petition to Modify — State the material and substantial change, the current order, and the modification you are requesting
  3. Attach a supporting affidavit — A sworn, notarized statement of the facts establishing the change in circumstances
  4. Pay the filing fee — Varies by county; fee waivers are available if you qualify
  5. Serve the other parent — Service by citation through the district clerk (see the service guide for details)
  6. Await a temporary orders hearing — The court may set a temporary orders hearing while the case is pending, especially if immediate changes are needed

Modifying child support separately

Child support can be modified independently of conservatorship. Under § 156.401, a support order may be modified if:

  • Three years have passed since the order was rendered or last modified, and the monthly amount would differ by at least $100 or 20% from the guidelines
  • A material and substantial change in circumstances has occurred, regardless of how long ago the order was entered

Use the three-year rule

If it has been three years since your child support order, you may be able to modify support even without a dramatic change in circumstances — as long as the new guideline amount differs by at least $100 or 20%.
