Divorce Support Forums: partner income be considered in CS Modification?

Any advice in this would be greatly appreciated...

My live in partner got divorced almost two yrs ago. At the same time that his papers for the divorce were finalized so were the papers for child support. Forward two yrs and now his ex wife is taking him back to court to modify the child support payments. My question is, can my income be considered in the modofication of the child support? Also since the child support papers were last filed me and my partner now have a son together. Will that also be taken into consideration? Things are really tight for us now and if we were have to give the ex wife more money we might even end up loosing our house. Does the court even care about that? My partner already gives the ex wife a good amount of money and now she wants to get more because she can't afford to pay her bills. She also built an illegal efficiency on the side of her house that she does not claim to the court. Which seems very unfair to me. Is there anything my partner cdan do about that?
Any suggestions would be great.

Thanks
