If you and your codefendant signed the same copy of a plea agreement but signed it on different days;and also on your codefendant copy of the plea agreement their are written corrections stating a different amount of time,but you guys are still being charged with the same charges,is that valid?
It's possible, but frankly no one can answer your question on this forum because more facts are needed. You need to talk to your attorney about this. Only they can answer your question properly.
