|It sounds like this QCD might have been prepared to correct her previously recorded & misspelled name? Reason I think this is because the name was on there correctly AND incorrectly, and in several places. Even if that was the case, then still the signature line was incorrect, and that posed a problem for you, the notary.
DURING working hours - I definitely agree, call title and ask, let them dictate how to fix and take notes on who said to do what.
AFTER hours - I will do what I know for absolute certain is correct, recordable, etc. Every problem has a solution - though we can't always offer the solution. When you said "crossed out", you mean you stuck through with one, single line using black ink, and printed correction with black ink, and had her initial with black? But - if the QC was to correct her vesting to begin with, it may be that you negated the intent of the verbiage? Just trouble-shooting here.
Without having the exact verbiage on the front of the deed, it's impossible to know what really was being done, and w/o that info, it's impossible to offer possible fixes.
