Who gets what in a divorce?

The divorce is between a 40-something Man and his 40-something Wife. They have 2 children (11 and 16, both prefer mother). The mother takes care of the children 95% of the time and makes $90000. That would seem like a lot but its barely any because the husband doesn't have a real job and hasn't had one for probably 20 years except for one $15/hr job that lasted only 2 years, so the wife has to work 50 hours a week and still is the only parent that does stuff with the children. All he does is side jobs that only make him like $100 to $200 a week. He stays out late drinking sometimes and drinks almost every day (even if its just 2 beers). His side of the family treats her horribly. Not to mention the husband is close to just plain stupid. If it wasnt for the mother, the kids would be homeless.

CARS: the family has 4 cars. One of them is 10 years old that was bought by the wife for $18k is 2005 and another one that is 4 years old that was bought last year by the wife for $27k (she made/makes all payments). The truck is 20 years old and the wife helped pay for it ($1k). The only car the husband payed for was a 17 year old van that cost $600.

HOUSE: The house was bought in 2000 for $190k. The wife makes all payments. It is now valued at about $300k.

The only other semi-expensive things are classified as furniture (TVs, sofas, computers, etc) and were all payed for by wife.

Questions: Does the wife have to worry about losing anything? If so, what? Is there any other advice you would give to the wife?
