Key legal question
Whether the executor had a duty to ensure timely funding and sale of shares for the agreed payment
Extracted holding
Yes. As executor and co-signatory of the agreement, he had to take the steps necessary to provide liquid funds on time.
Extracted reasoning
Tasks of an executor under Art. 518(2) CC include actions of this kind; the executor is subject to the same liability rules as an agent, so Arts. 398 and 97 ff. CO apply.
