Lost Your Contractual Agreement Bond Papers? Here's How to Get a Duplicate When Both Parties Don't Have It

I am working as a Lecturer on a contractual appointment basis. I had my Agreement Bond papers signed at the time of appointment and at every academic year renewal of service. Somehow, I lost my copy of the Agreement Bond papers, and the same is also not available with the other party. How can I get a duplicate of the contractual employment Agreement Bond papers?

Since the original papers are missing, and you are unable to trace them, a fresh agreement can be made mentioning the previous contractual appointments and can be jointly executed.
