The Bank's Mortgage Department are usually pretty busy. For my case, I directly contact the Bank mortgage officer and the docuemnts are ready only 2 days before the settlement day!!! She even personally passed it to me at my doorstep to squize more time from posting it out.
Anyway, don't worry too much about the settlement date. There are usually a few days buffer or even longer time allowed for the "Final" settlement to take place even the pre-arranged settlement date has passed. Because unexpected collision on any parties during the settlement process is expected to happen, most of the time
