So you’re dealing with a JDB? Ordinarily, I would think that improves your chances of settlement, since they paid cents on the dollar for the privilege of collecting from you but. . . .
You started with two strikes (a judgment) against you and I strongly suspect that you’re not prepared to contest this. (Incidentally, that’s a shame since the scuttlebutt is that Midland’s suits are notoriously vulnerable and they rely more on numbers than quality.) In a “who blinks first?” contest, I think you lose.
Your attorney is going to hire somebody to handle negotiations? No disrespect to counsel. I encouraged local input, but I have been in such negotiations for many years, albeit at a much higher level than I suspect applies to you, and never had that happen. Motions to Vacate can be treated very liberally, and I also suspect that you could win that round. Have you discussed a game plan with counsel, in the event you’re forced to try? Did you engage someone experienced in this area? (Those are rhetorical questions.) My final salvo would be to suggest that you get your retainer agreement, which could be for a “phone hour to multiple hours” particularized in writing before going much further.
