I have 1+ years of experience and I am a background checked and a member of the NNA.
I make sure to go over all the pages and verify all signatures, initials, and dates are complete and properly filled out. All the documents are triple-checked. Mistakes are rarely made. If by any means it happens, I make sure to fix it ASAP.
As soon as the signing is done, documents are returned promptly and on time. I know my local FedEx drop-off times and will make sure to keep you informed throughout the process.
