You have asked a few questions here, so let me try t address them one at a time:
-- this is available where there is a marital standard of living which one party cannot achieve post-divorce because of an inability to earn an income level sufficient to live at the former marital standard and the other party has an ability to pay support. In an 8 year marriage
, you likely loved a lifestyle that you cannot replicate through your own earnings. For some period of time, alimony would seem like a possibiity in your case. Your ability to work full time is an issue as you say you cannot, he argues you can. Working less than full-time (if legit), increases the support needed by you.
The court can order interim support during the pendency of your case or order him to maintain the status quo until final judgment, which brings up the rhetorical question of why would you leave if you have nothing and heis taking care of all the bills.
Distribution of assets -- assets acquired during the marriage by one, or both parties, from their work efforts, are generally marital assets subject to distribution. The marital home is subject to distribution. He has a claim that the down payment on the home was his before marriage property - however, that was 8 years ago and courts may not give him 1000% credit for that premarital component. All of the mortgage payments during the marriage are marital payments providing you with equity in the residence. Same for other assets.
Legal fees - you can make an application to the court for counsel fees and the court may grant it. However, the court might also look at how much in assets you are getting in the divorce and decide you can pay your own. If you have a joint credit card, put counsel fees onthat as the debt will have to be allocatedat the time of the divorce.
With your asset scenario and his income level, you have to get a legal consult on your case to make smart decisions moving forward, before you take action.
