I have only seen it done once and not in its entirety. You still have a duty and an obligation to pay child support. However, I have seen it drastically reduced due to a parent being the minority shareholder in a three person corporation that generated millions annually. The majority two shareholders voted to reinvest all but $80,000 or so per partner back into the company. It allowed his counsel to argue that even if the minority shareholder was to vote to retain a larger amount he was helpless to do so. Further, the court should have no jurisdiction over the majority as reinvesting profits is done in common practice as good business sense. The court had no choice but to set the income at $80,000 for purposes of child support calculation.
