Shannon,
One of our companies "niche" specialities is exactly what you are looking for!
We track down defunct companies & their officers and get them to execute either missing assignments and or releases besides fixing title policy problems for our customers.

There are alot of title companies out there that have problems getting other mortgage companies release departments to either send them a release for recording or record a release not to mention mortgage companies trying to release mortgages with title chain problems..

Most likely we either know someone in the organization, have contacted them for possible business, run across the name, they are or have been a client or one of our clients know who they are and how to contact them.
With 29 years experience in the mortgage arena, we can help!
