(1) A transaction is deemed to be performed on the date when its legal effects arise.
(2) If legal effectiveness of a transaction requires registration in the land register, in the ship or shipbuilding register or in the register of liens on aircraft, such transaction is deemed to be performed as soon as the other conditions of its legal effectiveness are met, the debtor’s declaration of intent has become binding and the other party has requested registration of such transaction. If the registration of a priority notice was requested in order to secure the claim on the transaction, sentence 1 applies, with the proviso that such request for priority notice stands in lieu of the request to register the transaction.
