Hey there, old friend.
You are correct, the DOFD should be the month you filed BK. However, since the item will drop from your credit 7 years from that date, if the DOFD listed on your credit report is OLDER than the month you filed, let it be. This will mean that this item will fall off your report earlier than it technically should - which is good for you.
Further, your score is partially based on how long it has been since you have had any kind of delinquent account, so the longer the period from today and that date, the better.
Hope all is well. Feel free to PM me anytime. I was discharged in Oct 07 as you may recall, but still have not closed!
