Modifying Support: Changed Circumstances Cut Both Ways

Support orders are living numbers. His raise is your motion; and knowing how modification works also tells you how to defend the order when he cries poverty.

What California Law Says

Modification requires a material change of circumstances — income shifts, timeshare changes, new mandatory add-ons — measured from the last order, and takes effect no earlier than the filing date of the modification request under Family Code section 3653. Below-guideline stipulations modify freely upward to guideline.

How to Collect, Step by Step

1. Monitor for upward triggers: promotions, new employment, inheritance windfalls, reduced visitation.
2. File promptly when a change lands — retroactivity to filing means delay donates money.
3. Demand current income and expense declarations and employment records in the proceeding.
4. Defend downward attempts with the imputation toolkit when his hardship is voluntary.
5. Recalculate guideline with current numbers and get the new order entered cleanly.
