Is there a cap on how much undue hardship can reduce the table amount of child support?

There is no fixed numerical cap, such as a maximum percentage, set out for how much an undue hardship finding can reduce the table amount; instead, the adjustment is meant to be tailored to the specific circumstances that established the hardship in the first place, so the reduction reflects what's actually needed to address that particular hardship rather than a standard formula applied across all cases. Courts have discretion to craft an adjusted amount once both stages of the test are satisfied, informed by the extent of the qualifying circumstance, such as the actual dollar amount of debt payments or travel costs involved, and the results of the household standard-of-living comparison.

Because there's no set formula, outcomes can vary significantly between cases with superficially similar circumstances, depending on the specific numbers involved and how the comparison plays out. A court is unlikely to reduce support so far that it undermines the basic purpose of child support, and undue hardship adjustments in practice tend to be measured rather than dramatic, but there is no statutory ceiling stated as a specific number. Because the outcome is fact-driven, getting a realistic sense of what adjustment might actually be achievable generally requires a detailed look at the specific numbers in a given case.
