may i ask y you wanna divorce with your hubby?
custody- usually, the judge will decide which living environment is more suitable for the kids, so might not necessarily for you to get the kid's custody, unless your husband gives up the custody to you.
if im not wrong, usually the judge wont seperate the kids, n most of the time, the custody will be given to the mother. but then again, have to see the environment n your ability.
housing- im not very sure if you can sell your house away anot, but i doubt so. you can still live together after you divorce i think.
