I have spoken with several mediators and L and they all agree that the best approach for a uncontested D is that I would file and we would work with one L to dissolve the M. I will retain the L and have the documents prepared. You can work with the L that I retain to sechedule when you would be served the papers. If this is okay with you, let me know and I will begin the process.
You just showed your hand. If your wife has a L then she is not planning on going this route. Does your W have a copy of the pre-nup? If so does does her L? Why would you ask if this is OK? If you have been advised to file first and have more info your pre-nup isn't as strong as you thought, your wife hasn't made any effort to be around you..... What are you waiting for? Filing isn't the end, it does make the BGPs ride up a little though.
