# California AB 2393 (20112012) — Family law: child support formula.

Under existing law, the parents of a minor child are responsible for supporting the child. Existing law establishes statewide uniform guidelines for calculating court-ordered child support. These guidelines provide that if an obligor's net disposable monthly income is less than $1,000, there is a rebuttable presumption that the obligor is entitled to a low-income adjustment that reduces the child support amount. Under existing law, this presumption may be rebutted by evidence that applying the low-income adjustment would be unjust and inappropriate.
