No, but they can contact him again under the pretense of renegotiating the mortgage agreement. Considering this is a bank that buys bad debt they most likely will use that as an excuse to harass him for a while until the bankruptcy is concluded, whatever the outcome may be.
This is the last time I'm going to say this. They can not put a lien on the WAKhando unless A. Phil's case is dismissed with prejudice and B. they actually finished the foreclosure proceedings AND have a deficiency judgement. It even says in the order for relief from stay that, in the event that Midfirst could somehow bully Phil into actually agreeing to keep the mortgage, such an agreement would be non-recourse i.e. Phil could not be held personally liable. I know it's fun to think Phil is getting fucked now but that's going to be entirely up to the trustee. If she grants his Chapter 7 wish then MidFirst is going to be another detractor that is outlasted by Phil's pigroach luck.
