It goes cheerfully on. Acceptance, which is generally also a very difficult topic to digest, took place on Friday for the interior doors. I was not there. Now I receive the protocol based on the VOB. However, the offer and order confirmation (as the only contractual documents) do not refer to these, thus a work contract according to the Building Code. Therefore, now my requests to the architect (I am tired of already pre-chewing the result): 1. I ask you to check whether this assessment is correct. 2. I ask you to check whether the client suffers a disadvantage due to acceptance according to VOB instead of the Building Code. 3. I ask you to check whether the acceptance protocol or the acceptance is valid. 4. I ask you to check whether the due date of the “final invoice”, regarding a possibly invalid acceptance, has been reached. At the same time, the door installer issues an invoice without the word final invoice and without a note that it is conclusive. This is released to me as the "final invoice" by the architect. 5. I ask you to check whether this is a final invoice. 6. I ask you to check whether the payment deadline, if this is a final invoice, is legally in order. Then there is also a note on the acceptance protocol that another trade damaged a door. Here, too, there is some uncertainty about the transfer of risk and the burden of proof. Since I have checked the last five invoices, none of them have been "clean".
