Good question... I’m afraid not, because otherwise one could just go to the notary, but that’s not possible yet.....
Then he doesn’t have to wait for the creation/registration of the land charge at all.
So the only option left is the annotation of conveyance, otherwise there will be stomachaches!
Our notary appointment for the house financing was in May, with surveying, registration of the surveying and formation of the parcel and approval from the bank, 5 months have passed.
