Key legal question
Whether the lease contained a sufficient agreement on ancillary costs under Art. 257a(2) CO
Extracted holding
Yes. A reference in the lease to the adjacent special provisions for WEG apartments, with the detailed ancillary-cost rules placed side by side in the same four-page document, was sufficient.
Extracted reasoning
The tenant did not need to consult separate general terms; the ancillary-cost clause was clearly identifiable, prominently labeled, and embedded in the lease itself. This was not an impermissible global incorporation of standard terms.
