My question involves child support in the State of: California

Im having a bit of difficulty figuring out the Judge in my case, It appears that he has purposly left out spousal support that my ex-gf gets from her previous marraige in caculating the income of my ex and myself for the purpose of child support. From my understanding, ALL income is counted towards what each parent is able to provide for the child. I believe he did this so that my ex would not have to pay me, the NCP even though she has full custody. My income is very limited right now, so I dont pay her much. It just galls me to think that these fools can get away with something like this. I really dont want my ex to pay me anything, I just want a fair proceeding. Who is supposed to be watching over these judges? who can I complain to if this continues to get out of hand? I would really hate to think that they can manipulate the very wording of the family code to their advantage as they deem fit......
