Kernrechtsfrage
Whether the bank incurred liability based on reliance created by the financing confirmation and silence
Extrahierter Entscheid
No special legal relationship or attributable conduct by the bank established a protected reliance claim; the buyer could not infer consent to release the mortgage without full payment.
Extrahierte Begründung
The bank merely required a financing statement as a condition for the builder's credit. The disputed clause originated from the buyer's bank and was ambiguous; under the ambiguity rule it was construed against the drafting party. The bank's silence did not amount to consent.
