Key legal question
Whether the signed care contract and related documents justified provisional debt enforcement opening for the full claimed amount.
Extracted holding
Only amounts clearly deriving from the signed contract and properly substantiated documents could support provisional opening; unsupported care-cost items could not be included.
Extracted reasoning
Under Art. 82 SchKG, the claim must rest on a signed debt acknowledgement with a determinable amount. The invoices lacked signatures, and the general conditions and price list were not filed, so the claimed additional care costs were not verifiable.
