How to Cancel a Stock Certificate (5 Steps)

Retrieve the stock certificate from your broker, or vault, if it is stored in your possession.
Flip the stock certificate over and write 'VOID,' in bold letters, across the back of the certificate. Your broker can perform this task for you.
Record a date of cancellation, such as 'January 01, 2010' or '01/01/10.'
Jot down the transaction date printed on the right side of the certificate. Record the date in your books.
Figure the age of the canceled stock certificate. For example, 'Certificate 1234 was canceled on January 01, 2010, just nine months after the original transaction date.' Record this information in your books.
