You can write void on the check.
Write Void in the check register and list it on your check log as a voided check.
In the memo section why it was voided- (returned, wrong amount etc.) and tear off the signature section of the check.
Then remove the check from your check book and staple on a piece of paper and keep with the rest of your records.
I don't use Quicken but Excel. What I do is keep the check on the "Worksheet" where all my checks, deposits are listed but in the $ column type VOID. That way the check is logged.
Thanks, I guess I was looking for a quick fix as in Quicken where the check is voided but the info is still there. I suppose I could just delete the check from Finance Manager and keep the actual voided check in the Treasurer's files.
