All depends on the lawyers... A good lawyer will prevent him from getting custody or alimony, and yes he will have to pay child support, Prolly very little at first, but as soon as he gets a job, it will be recalculated etc... As far as the infidelity goes, it could be very influential in deciding custody and alimony, but has to be proven with evidence, suspicion isn't usually very effective in court. The important thing is that she seek legal council as soon as possible, and definately before anything is sold etc...
