Key legal question
Whether the notary breached his duty by failing to verify the buyer's identity and civil capacity.
Extracted holding
The notary did not act arbitrarily in being found to have no breach, because systematic checks are not required absent concrete doubt.
Extracted reasoning
Under the old Vaud notarial law, the duty to verify capacity arises when there are indications of doubt; the cantonal court could reasonably find no such signs here.
