PS - IL is not a community property state (50/50). IL is an "equitable division" state, in which property is divided according to "fairness", which is not necessarily 50/50. There is no formula. Generally, keeping the children's lifestyle as status quo as possible is how judges like to divide the marital property pool. In general whomever gets residential custody of the kids gets the lion's share of the assets (not so in our case with my DH kids simply because giving her all the $ meant she would give us the kids, but that is unusual and was by agreement).
Just wanted to put that out there. IL is also not a presumptive joint custody state.
Also, almost 100 pct of the time in IL what is written in the emergency/temporary orders (child support, alimony, visitation, property, etc) is very often what the plenary (final) orders are drawn from. To alter greatly from temporary orders is an uphill battle in general. Family judges like to see consistency in the case and very little contention. They like everything to be very orderly and civilized, people that vary from that are apt to get slapped down in court. I saw it happen with DHs ex dozens of times.
