along with their signed TIL
Again there is no regulatory requirement to have this document signed.
We don't require signatures when we don't have to, requiring them is just one more thing the examiners can criticize you for when you don't have the signed form, and may the compliance gods have mercy on you if you have all signed forms in protected class files and don't happen to have one in a non-protected class file.
Don't get me wrong. I'm not saying these procedures are wrong or prohibited, I'm just saying such procedures can lead to more problems than they prevent, but as the old saying goes. If it's not broken, don't fix it. But watch for cracks..
