According to my Duden, verschreiben can mean "jmdm den Besitz einer Sache urkundlich zusichern". I cannot think of a perfect English translation for that but what about "costs of deeds" or "document compilation costs". Try googling "costs of deeds" and "notary expenses" and you get the hit below - bit dodcy because it is Belgian, but perhaps you can come up with something a bit more elegant than "costs of deeds"...

or service costs or legal fees, since real estate transfer is always handled by a lawyer.
