I am currently facing the same problem. I want/have to register a land charge and have read that the certified draft is partly sufficient. How exactly did it go with you? Was the bank okay with it or did they not care? The notary obviously didn’t see any problem with it either? Since it is about several hundred euros, I would be very grateful for an answer. A first inquiry at my bank was unfortunately answered with "that doesn’t work for us, we do it as usual." But I think they didn’t quite understand it either and feared not being able to enter the land register...
