Good day, I owe my car financing a month, so I’m redeeming the sum X at Santander. Then they should send me the kfz letter (and no the debt bank does not want the letter as a pledge). But now the following problem, the buyer of my car will come by next Friday and want to pick it up, now I think the letter is not there within 3 days. Can you tell me if the car letter is still legally valid when I call the Santander and ask e can you fax it to me by fax (with timestamp or so) because the time window is very tight?
