This is from my Title & Escrow company:
(And as the buyer, I did not have to have anything notarized.)
General Timeline for Closing Your Disney Purchase:
As soon as contracts are signed (no mention of having them notarized), they are sent to Disney for ROFR. Disney may take up to 30 days to approve the sale.
After Disney approval, closing documents sent to buyer/seller.
Buyer sends funds. Seller sends "properly signed and notarized deed." When both are received, deed is sent to be recorded.
Upon receipt of your recorded deed, a copy is made for Disney and mailed with any fees due and the original is then mailed to you, the buyer. Please allow 2 weeks from the time you receive your deed to verify owernship has been changed.
