Key legal question
Whether Swiss courts remained competent to order maintenance measures after the German divorce action was filed.
Extracted holding
No Swiss protective jurisdiction existed after the German divorce proceedings were pending; maintenance measures had to follow the divorce forum, and no exceptional gap in legal protection was shown.
Extracted reasoning
Existing protective measures continue until changed, but after divorce proceedings begin new measures may only cover the pre-filing period. An Art. 10 IPRG safety jurisdiction requires a legal-protection gap or unenforceability/untimeliness abroad, which was not demonstrated because German law allowed interim maintenance orders and enforcement in Nürnberg was feasible.
