Copies are generally accepted and can be introduced as evidence in court. The only time originals are required is when there is a question regarding authenticity or the correctness of the documents. For instance, if you challenged whether or not you signed the documents, the originals would be preferred but not required if a forensic document examiner were required to do an examination of your signature, etc.
I do not think that original documents are ever destroyed until the loan is paid off.
Most of my practice is dedicated to bankruptcy litigation and I'm a BV rated Martindale-Hubbell litigation attorney and also a Super Lawyer in the areas of real estate and bankruptcy.
I am comfortable with the questions posed and subject matter. Your initial question was about what proof was required to validate a loan, and I think that's been answered.
I haven't seen a question about MERS, which is a private company - not a branch of the government - that simply created a database to keep up with loans, owners of those loans, transfers from one lender to another, etc.
Nevertheless, I'll be glad to opt out and allow someone else to assist you.
The question is open....
Have a good night.
