I think you should hire a lawyer, even if it is to hire someone to merely review the agreement before you sign it. You may not need a lot of legal advice, but if you sign a document without having a lawyer assist you, you may be signing something that is not in your favor. Additionally, if he has a lawyer, you would benefit from having someone advocating for you and making sure the process goes smoothly. He also be less likely to try to push you around as much if you have a lawyer as it seems he is trying to do by asking you to pay his lawyer fees.
If he has an attorney, you definitely need to be represented as well. You would be at a significant disadvantage if you attempt to represent yourself against an attorney who understands the in' sand out's of the legal system.
First of all, everyone really needs a lawyer even for that supposedly "simple" divorce. But now you are in a contested divorce versus a lawyer. You NEED counsel. I can almost promise you that it would be a very expensive mistake to respond without counsel.
