It's unclear from your question, but considering he has a new wife--I am guessing you are already divorced. If you are already divorced and are seeking to see how much he makes because he is not paying support, you should be aware that he still has to pay you support anyway.  There are ways of going after bank accounts and wages to get those arrearages.  You could also levy on some types of pension accounts.If you want to know how much he makes, you can file a post-judgment request under California Family Code 3664, using form FL-396.  Your Ex has to respond.  If he doesn't and you do know of his employer, then you can file an FL-397 with his employer. There is no governmental organization where you can secretly pull all of his financial stuff using his SSN.  The FL-396 is the best place to start.
