I am engaged to be married in CA- my fianc� and I pay child support to our "x"s but no alimony. One child is in the state of CA- the other is out of state. Will our incomes be combined and at risk for a higher combined income- higher monthly Payments, or will our salaries be looked at individually? Do we need a Pre- nup to protect our individual income? When we have our updated child support conference do we claim only our individual child or all children after we are married.
