Key legal question
Whether the 16 November 2002 donation agreement constituted a valid written assignment of the registered shares.
Extracted holding
No. The agreement expressed only the obligational donation arrangement, not a sufficiently clear assignment declaration in the required written form.
Extracted reasoning
For Art. 165 OR, the assignment intent must be apparent from the document itself to third parties. The contract was titled and structured as a donation agreement and under the heading 'obligational transaction' did not clearly show a dispositive transfer of the shares.
