How Can Child Support Orders Be Modified After a Significant Life Change?
Your child support order was built on a snapshot of your family: A parent’s paycheck, the child’s health insurance, and where the child lived when the judge signed it. When that snapshot changes, Texas law lets a court modify the order if circumstances have materially and substantially changed, or if three years have passed and the amount differs from the state guidelines by 20% or $100.
Timing matters. A new amount generally applies only to payments due after the other parent is served with the case or appears in it, so the old order controls until you take formal action.
At The Torres Attorneys, we help parents in Corpus Christi, Dallas, and Fort Worth decide whether their situation meets that standard and which route to a new order fits, whether an Attorney General review or a petition in family court. A consultation lets us review your current order and explain your options.
How Child Support Works in Texas
Texas sets child support mainly as a percentage of the paying parent’s monthly net resources, meaning income after deductions such as taxes and the child’s health insurance. The guideline starts at 20% for one child and rises 5% for each additional child, reaching 40% for five or more. Since September 1, 2025, those percentages apply to the first $11,700 of monthly net resources, up from $9,200.
Once a judge signs the order, that number is the legal obligation, regardless of what the parents later work out. The Attorney General’s office states that informal agreements between parents do not change a court-ordered amount. A paying parent who cuts payments on a handshake deal can still owe the full balance, and a receiving parent who accepts less may struggle to collect it later.
How to Make a Modification
A Texas child support order can change in only two ways: through the Attorney General’s Child Support Review Process, an in-office negotiation available when you have an open case with that office, or through a court hearing on a suit to modify filed in the court with continuing, exclusive jurisdiction, usually the court that issued the original order. Either parent can ask, and the payment can go up or down easily because the new figure is based on current income.
Either way, you must meet one of the grounds in Texas Family Code Section 156.401: a material and substantial change in the circumstances of the child or a person affected by the order since it was signed, or the three-year rule. Under that rule, if three years have passed since the order was set or last modified and the monthly amount differs from the guideline amount by 20% or $100, the court may update it without proof of a major life event.
One exception matters for many parents. If you agreed to an amount that departs from the guidelines, the three-year rule is unavailable, and only a material and substantial change will support a modification. Checking that language in your order is central to our child support modification work.
Life Changes That Qualify for Modification
Texas law does not list every change that counts as material and substantial, so courts weigh the facts of each case. Common examples, some written directly into the statute, include:
A significant rise or drop in the paying parent’s income, such as a layoff or a much higher-paying job.
New children the paying parent must support, which can trigger the lower percentages Texas uses for parents with children in more than one household.
A change in the child’s health insurance coverage or its cost.
The child moving in with the other parent.
The paying parent’s incarceration for more than 180 days, or release when support was reduced or suspended during that time.
The reason for an income change matters too. If a court finds a parent is intentionally earning significantly less, it can base support on earning potential rather than actual pay.
Some changes do not qualify. A court may not count a new spouse’s income, the receiving parent’s higher standard of living is not a reason to raise payments, and a joint conservatorship order alone is not grounds for a change.
Steps to Take to Start the Process
File a formal request early, because a new amount generally reaches back only to the date the other parent was served or appeared in the case. Months of informal negotiating can mean months of payments no court can adjust later.
From there, the process usually looks like this:
Review your current order, noting when it was signed or last modified and whether the amount was agreed to or follows the guidelines.
Gather proof of the change, such as pay stubs, tax returns, a termination letter, insurance statements, or a new child’s birth certificate.
Choose your route. With an open Attorney General case, you can submit a Request for Review of your court-ordered amount online or by mail, and the office asks parents to send only one request to avoid delays. Otherwise, or when facts or custody are disputed, a petition to modify goes to the court with jurisdiction over your order.
Make sure the other parent is properly served or formally appears, which sets the date that controls any change.
Keep paying under the current order until a new one is signed, because arrears that build up in the meantime will not be erased.
If the other parent agrees to the new amount, the case may resolve without a contested hearing. If not, a judge decides based on the evidence each side presents.
