Had a long conference call with The Mouthpiece and associate. He's pretty much fed up with the counter-counter-counter game. We're drafting a letter to The Other Side that proposes everyone sit down with a mediator because, as The Mouthpiece put it, "Someone needs to explain to them what the law is in the Real World."
If they demur or fail to show, we're straight to the courthouse.
As far as the house kerfluffle goes, his recommendation was: stay put. If STBX stops paying the mortgage, don't pay it; she can't list it without my signature, and it'd take at least a year for the bank to get around to having me evicted (and since I'm an owner STBX can't have me evicted), and since The Other Side is holding "an immediate house sale" out as a threat to produce a "reasonable" (i.e., the one STBX likes) settlement, it's about time to call their bluff. Is STBX willing to take the hit to her credit rating that a foreclosure would produce? Let's see just how hard a game of hardball The Other Side wants to play.
