Based on what I understand of your question, you appear to asking about the validity of the Mortgage Electronic Registration System in holding title to your property while a tax except trust made transfers (possibly after the close date?) in violation of the Pooling and Servicing Agreement. Massachusetts recently had a ruling on the subject in Culhane v. Aurora Loan Servicing of Nebraska, which is discussed quite well in the Massachusetts Real Estate Law Blog located here: http://www.massrealestatelawblog.com/category/foreclosure/
Perhaps you can review the blog and formulate your question a little clearer.
