What is the process for issuing new stock certificates because of a stock split?

Question

My company (an LLC) did a 10-for-1 unit split and investors can send in their old certificate for a new one if they want. I'm just wondering if the old certificates need to be voided and/or recorded in a certain way once we receive them.

Answer 1

The returned certificates need to be either manually voided or destroyed as they are being replaced by newly issued certificates.
