Hi Bklyngrl,
I am in NY too, and if you agree on things, it's ok to use one lawyer, and keep it simple.
There is also a company called Divorce Associates, I think in Manhattan, that will do the paperwork, and it's very inexpensive, and you just have to work it all out with regard to division of your assets yourselves.
Divorce doesn't have to be expensive, but if you each get your own attorney, then they will, from my experience, make it messier and more expensive than it needs to be.
I'd look around on Google...you will find resources.
Sending good thoughts your way.
