Divorce Support Forums: College and who's income could be considered?

I understand in CS issues, the NCP/CP and not usually spouses' incomes are considered. My husband's son lives w/us fulltime and attends college. Mom doesn't pay anything but agreed not to pursue CS increase last summer "in order to do her share". Husband's 16yr old daughter lives w/mom who just moved in w/wealthy boyfriend. She no longer has housing or utilies but wants more CS in '09 in addition to possible college $ from us for her daughter who'll attend in 2010. Ex has her own income but stepdaughter will most likely get financial aid since her mom's not married to her wealthy boyfriend. Also, stepson got fullride sports scholarship for next year and will only need help with spending $ from us which is great but could count against "help" his dad's provided when evaluated in '09.

Order was till age 18 but husband's ex talked him into extending it 2more years vs increasing CS last summer. Now, looks like we're in this for college too. The kicker, my son starts college in '09 right when all this is going on. I have my own CO w/his dad and hope to keep our situation out of court if at all possible.

So whose income could be considered in all this? Thanks!
