Did that happen to you?
When you have an escrow the escrow officer provides the wiring instructions. Then the lender uses those instructions to wire the money. The escrow officer would have to balance their account, so if they have money in the wrong account or don't have money they are going to let someone know. If the lender made a mistake I sure would like to see all parties, the receiving account, bank, escrow and lender make it all right.
I've never heard of this happening. Why do you ask?
