Key legal question
Whether the non-notarized transfer agreement for the GmbH share was void and the defendant could invoke the form defect
Extracted holding
The transfer agreement was formally invalid; the defendant's reliance on the defect was not abusive because the agreement was concluded and partly performed in ignorance of the form requirement.
Extracted reasoning
Art. 791 OR requires public notarization. The courts found the parties did not know of the form requirement and the defendant objected once aware. In such circumstances, no abuse of rights or healing of the defect was established.
