This is just an example of what I do if closing is at 9am the next day.
I call and email to say, “Please kindly have the docs ready for printing by midnight because I will need time to print, review, flag and have everything ready before closing at 9am. If you are not able to get them in by midnight please reassign, Thank you.”
Luckily, 99.9% of the singing and title companies have the docs in between 12 hours to 7 days before scheduled signings for me:) But I never print docs until the night before! For those who are slow in getting the docs in, I give them at least 6 hours to get them in otherwise they will need to reassign to someone else.
