Child Support Modification in Southlake, TX: When Income Includes Bonuses, Equity, or Business Earnings
In a city like Southlake, a parent's income is often more complicated than a single paycheck. Bonuses, equity compensation, commissions, and business earnings can rise and fall from year to year. When income shifts, or when a child's needs change, many parents wonder whether their child support order can change too.
Can child support be modified in Southlake? In some situations, yes. A court may modify support when specific legal requirements are met. A change in income, or an informal agreement between parents, does not change a court order automatically.
The Two Main Routes Under Texas Law
Under Texas Family Code Section 156.401, a court may modify an existing order when one of the legal standards is met. Generally, a parent may seek modification if:
There has been a material and substantial change in circumstances relating to the child or a person affected by the order, since the date of the earlier order or underlying agreement.
At least three years have passed and the guideline amount differs enough. The current order must generally differ from the guideline amount by at least 20% or $100.
Exceptions apply, and meeting a standard does not guarantee an outcome. If parents agreed to a support amount that differs from the guideline amount, modifying it can be more difficult.
Why Variable Income Raises Special Questions

Texas guideline support is based on the paying parent's net resources, which can include more than base salary. That makes documentation especially important for Southlake parents whose pay is not fixed.
Equity compensation. If part of your pay comes from stock options and other equity compensation, records showing how and when it vests or pays out can matter.
Bonuses and commissions. A single unusual year may not show a lasting change. Pay records covering a longer period help show the pattern.
Business and self-employment income. Tax returns and business financial records help explain real earnings.
Military pay. Deployments and allowances can change a family's finances. See military divorce in Southlake for how service affects family-law decisions.
A temporary setback or a voluntary career change does not automatically qualify. The court looks at the facts and the applicable standard.
Spousal Support and Child Support Can Interact
If your order includes spousal support, changes in income may affect more than one obligation. This guide to alimony and spousal support in Southlake explains how the two differ.
Other Changes That Commonly Prompt a Request
Higher child expenses. Medical, insurance, and educational costs may grow. Records supporting the request help.
New living arrangements. Where a child lives and child support are separate legal issues. Texas law provides that joint conservatorship, by itself, is not grounds to modify support.
Does Moving Within Southlake Change Anything?
A move within Southlake, or between Tarrant and Denton counties, does not automatically change a support order. The court with continuing, exclusive jurisdiction generally keeps an important role, so a move does not necessarily mean a new court.

Agreements Must Be Formalized
Parents can agree to a different amount, but until the order is legally modified, the original generally stays in effect. A parent who pays less based on an informal deal may face enforcement for unpaid support. Divorce mediation in Southlake can help parents reach a workable agreement, which can then be put into a legally effective form. For why clear terms matter, see Child Support Agreements That Work.
Timing Matters
Under Section 156.401, a modified amount generally applies only to support accruing after the earlier of service of citation or an appearance in the modification suit, subject to exceptions. A later order will not automatically erase support that accrued earlier, so prompt advice is worthwhile.
Records to Gather
The current order and any earlier modifications
Pay stubs, tax returns, and records of bonuses or equity payments
Business financial records, if you are self-employed
Medical, insurance, and other child-expense records
Documents showing when the change occurred
Southlake Child Support FAQs
Can I stop paying support if my income drops?
No. An order stays in force until it is legally changed. Keep following it and explore a modification promptly.
Does a large bonus mean support goes up automatically?
No. Support changes only through the legal process, and the court looks at the circumstances and the applicable standard.
Does equal parenting time reduce support?
Not automatically. Joint conservatorship alone is not grounds for modification.
