If you are seeing an associate or solo practitioner, their hourly rate might be under $200. If it's a partner in a large firm it could be much higher.
Don't give him a copy beforehand, since he will charge you to look at it and you have no way to know if he took 5 minutes or an hour.
While they may charge a fraction of an hour for the smallest service (1/4 hour for a 2-minute phone call), they will likely charge you a full hour for a consult. If your appt is for one hour, make sure it doesn't go over, and that you don't give him any work to do afterwards. He can read the 5 pages in front of you and give you an opinion on the spot. If he says he needs to research something, tell him you thought you were working with someone knowledgable about divorce in your state, thank him, and leave.
Don't ask your H to pay your L fees. That will complicate matters and only save you $200 if that's all you're using the lawyer for. In contested cases, L fees can run to $10,000 quickly, over $40,000 in one case I saw here recently, and then it becomes worth it. I resisted this in my case, because I didn't have a lawyer and didn't think W needed one either. I didn't want W fighting me using my own money.
If you are worried about this, call the office and ask the secretary what this lawyer's standard hourly rate is. It is not a secret, but they don't like to tell you until afterwards.
