Just happened to see your post here and it brought to mind a couple of thoughts.
This whole idea of "working with her on it(A divorce)" and somehow going to a lawyer together would not work, and I will tell you why.
first of all, in a D each person hires a lawyer to look after
best interests. That does not mean you set out to cheat your W. It just means that your lawyer will look at your situation, and what could happen in the future, and advise you accordingly. Likewise, I would suggest that your W would get her own lawyer, just to make sure she has someone giving her good,solid advice.
During my D, my Ex refused to pay a lawyer. I hired one, but he kept saying it was too expensive. But for me, I knew that I was not in a good frame of mind to make decisions that would affect me and my children for ever. I wanted to have someone else help me out. My lawyer made it clear from day one that she could only represent one person, and I was her client. If he had any questions, he could not ask her - he had to get his own lawyer. She even made him sign a statement that she had advised him to get legal representation but he refused. My lawyer wrote up the paper work, he stopped by her office to sign, and that was it.
Of course, only a few short months later he was telling everyone that I had "screwed" him, took him for everything. That my lawyer had cheated him out of everything. Of course I knew it wasn't true - and I knew that my lawyer had told him on several occasions that he really should hire a lawyer just to have a second opinion before he signed - but he refused. Looking back - I wish he would have spent the money. that way someone else could have given him advice.
Also - your lawyer will be able to anticpate a LOT of things that could happen in the future, and help you to prepare. My boys were young at the time. My lawyer put in writitng that child support would continue until they turned 21 as long as they were in school.(many times support stops at 18) My oldest is in college right now, and turns 21 this year. I am so glad that he has been able to recieve that check each month from his dad to help pay for college. If I did not have it in the D papers, his dad never would have paid it. That is one of many things a lawyer can help you with.
Your WW will spend the next couple of weeks on the internet looking for free advice. And she will find out that D is about way more than just filling out a form, getting it signed, and then you get to date anyone you want. In a way, it is good that she is looking this up and seeing how complicated it is. She needs to udnerstand that tearing apart a family is a BIG deal, and should not be taken lightly.
If she does go to a lawyer, you will hire one yourself. But that does not automatically mean that you both will spend thousands of dollars. You can each seek out your own professional advice, and still come to an agreemetns without going to court. (in the end, I paid a total of $2500 to my lawyer. It was worth every cent)
you seem to be really worried about all this stuff. That is understandable. I still think it is way too soon to tell if she will follow through with any of it. She is getting the biggest reality check right now. But perhaps it would be good for you to make an appointment, and sit with a lawyer for 1 hour asking all your questions. See a professional. Ask the questions. I think it will calm your fears.
FYI - my ex saw a lawyer once. Most of them will go at least once. But 6 months later he still had not taken the next step. He talked about it - but no action. I finally got tired of waiting and did it myself. I hope you don't have to do that. But if you do - hire your own lawyer and tell her to do the same, so neither of you can claim you were "screwed".
