回复:想问问离婚配偶赡养费及财产问题, 在加州
"单算婚后收入,我能分到的部分基本上大约是多少" -- should be at least 50% (401K included). Potential more if you have the custody of the child.
"他说他买个房子给我住10年到孩子18岁,外加10K cash, then I will be on my own." -- Will child support be extra? If yes, basically, he is paying you monthly rent for 10 years. (You can treat the rent as alimony.) Sounds not too bad.
