UPDATE: Ally Financial's ResCap Wants to End Foreclosure Review Process
Looks like they are in bankruptcy and GMAC is also mentioned. They want the Bankruptcy Court to excuse them from the Independant Foreclosure Review under Chapter 11.
In 2010 I fought RH donnley corp. as a creditor and they were trying to skip out by filing an Omnibus objection on the debt they owed me. I stopped them in the Delaware court with a response to that objection and won.
It would seem to me that, anyone who has had a wrongful foreclosure from these institutions in the above link, and you have a foreclosure review number assigned to you, can file an objection with the court as a creditor in this case.
