Question juridique clé
Whether the rent-default notice and termination complied with Art. 257d OR despite errors in the stated arrears.
Solution extraite
The notice was sufficient because the tenant had to understand he had not fully paid the outstanding rent and was not actually misled about the amount due.
Motifs extraits
Minor inaccuracies in the calculation do not invalidate a notice under Art. 257d OR if the tenant still understands the payment obligation and the risk of termination; doubts about the amount work against the landlord only where they create genuine uncertainty.
