Is there anyway for me to track seller's movement?

I'm purchasing a new condo which already has its CoO done. The seller's agent told me this should make the closing process very smoothy. However, it turns out to be the other case - our closing date has been pushed for 2 months. I have checked the record and seeing its Tax Map has been approved 1.5 months before. However, the condo decalaration has never been posted on ACRIS. Right now I'm almost wondering if the seller is still moving forward and if there's anyway to check this (other than ask the seller's agent again). Could any one shed some lights over this? Also, is there anything else I should worried about before closing? e.g. any other paperworks that need to be approved by the SLOW gov. Thanks in advance for any advice :)
