Narrative:

I thought my CFI was to expire jul/xb/99. I went to the local FSDO to revalidate my CFI and discovered my CFI had expired. It was at this time I realized I had given a student a signoff on jul/xa/99 by mistake. To prevent this from happening again, I will check my expiration date on my CFI prior to any more signoffs. To correct this error, I plan to revalidate my CFI and give the student from the error a new signoff for a new check ride.
