Yes, his child support obligation MAY be reduced. However, if he VOLUNTARILY quit his job then you need to argue that it was his choice to take a pay cut and your child should not suffer because of it. The amount of money needed to support your son has not changed--you both still live in CA. Also, if your son will stay with you in CA full-time, then the timeshare upon which the child support order was based will increase so you may be entitled to more child support if you play your cards right. I'd suggest hiring a lawyer to help you with this one--the legal arguments can be a bit complicated. I'm including links below which may prove helpful. Good luck.
