If she wants to get lawyers involved, why tell you to do the work? B/c that is how female bullies operate. If she wants a D, make her to her own paperwork.

I think it's a threat, at the moment, to get back under her thumb. However, don't try to talk her out of doing the paperwork, or whatever. If she says anything further about "you" doing anything, you need to matter-of-factly inform her that if she wants it......she will have to do the work to get it. I think she has you so well trained, perhaps you didn't even question why you would look for lawyers, look up the paperwork, or whatever. It is a bad habit to follow her every word without, at least, questioning it yourself while going through all of this mess.

I'm not suggesting you initiate anything, but just like all bullies, you don't want her getting the idea you are trying to avoid her, either. Bullies believe you are afraid, when you try to walk around them.

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
