Key legal question
Whether the cantonal court could grant definitive enforcement for nachehelicher Unterhalt based on the separation order found in the archive.
Extracted holding
No. The enforcement title had to match the debt claimed; because the wife had enforced post-divorce maintenance, the separation order could not serve as the title for that claim.
Extracted reasoning
The creditor must present the title relied on, and the claim enforced must be identical to the claim covered by that title. The court went beyond the pleaded basis by searching for another title of its own motion.
