San Antonio Child Support Attorney

Child support matters carry real consequences for your financial stability and your child’s future. Whether you need to establish a new order, enforce payments the other parent has stopped making, or modify an arrangement that no longer reflects your circumstances, the decisions made in Bexar County family court will follow your family for years. Without an attorney who advocates specifically for you, those decisions may not reflect your full rights as a parent.

How Texas Calculates Child Support

If you are entering a child support proceeding, understanding how Texas courts calculate support can help you prepare. Under Texas Family Code Chapter 154, courts generally apply a guideline percentage to the paying parent’s monthly net resources. In many cases, the guideline percentages are 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more.

Courts may deviate from those guideline percentages based on the factors listed in Texas Family Code § 154.123, which can include the child’s age and needs, the parents’ financial circumstances, and health insurance or medical support obligations.

The 2025 Income Cap Update

As of September 1, 2025, the guideline cap used in child support calculations increased from $9,200 to $11,700 in monthly net resources. For one child, that produces a maximum guideline amount of $2,340 per month before any justified deviation.

If your order was finalized before September 1, 2025, the prior figures may still apply unless a court later modifies the order. If your circumstances have changed, you may have grounds to request a review.

Establishing, Modifying, and Enforcing Child Support in Bexar County

Where you are in the process determines the legal approach your case requires. Each of the three core scenarios follows a different path.

Establishing a child support order often begins with filing a Suit Affecting the Parent-Child Relationship, or SAPCR. Many parents first encounter the Texas Office of the Attorney General at this stage. The OAG can help establish and enforce support, but it does not represent either parent individually. We represent your interests and advocate for an outcome that reflects your family’s circumstances.

Modifying an existing order generally requires meeting the standard under Texas Family Code § 156.401. That usually means showing a material and substantial change in circumstances or showing that at least three years have passed since the last order and the monthly amount would differ by either 20% or $100 under the guidelines. A job loss, a significant income change, or a change affecting the child’s care may support a modification, depending on the facts.

Enforcement tools can include income withholding, license suspension, liens, passport-related enforcement, and contempt proceedings. Once child support becomes past due, reducing those arrears retroactively is generally very limited, so parents usually need to seek modification as soon as circumstances change.

Child Support for Unmarried Parents in San Antonio

Child support obligations apply equally to unmarried parents under Texas law. Before a court can enter a support order, however, paternity must be legally established.

For unmarried parents in San Antonio, paternity is usually established through an Acknowledgment of Paternity or through a court proceeding to adjudicate parentage. Once parentage is legally established, the same Texas Family Code Chapter 154 child support guidelines generally apply. Many unmarried parents rely on the OAG to establish or enforce support, but we can advise you based on your specific goals and circumstances.

Frequently Asked Questions About Child Support in San Antonio

Can I Modify Child Support If My Income Changes?

Under Texas Family Code § 156.401, a modification generally requires showing either a material and substantial change in circumstances or that three years have passed since the last order and the monthly amount would differ by at least 20% or $100 under the guidelines. A court reviews the facts of the case before deciding whether modification is appropriate.

Does the Texas OAG Represent Me in My Child Support Case?

No. The Texas Office of the Attorney General handles child support matters on behalf of the state, not either parent individually. A private child support lawyer in San Antonio advocates for your specific rights, whether you are seeking to establish, enforce, or modify an order.

When Does Child Support End in Texas?

In Texas, child support generally continues until the child turns 18 or graduates from high school, whichever occurs later. Support may end earlier in some circumstances, such as emancipation, and it may continue longer if the child has a disability.
