§ 1420 Writing Authentication Evidence

• •If someone says they got a letter or message from a specific person, they can prove it’s really from that person by showing it was sent in reply to something they sent first.
• •This rule helps show that a message is real and not fake.
• •It’s like if you text your friend and they text back—you know it’s really them because they replied to you.

You email your boss asking about your work schedule, and they email you back with the details.

If someone later says your boss never sent that email, you can prove it’s real by showing it was a reply to your original email.
