Questão jurídica principal
Whether the cantonal court correctly treated publication in the official gazette as valid service because no Swiss service address was designated.
Decisão extraída
The court held that, after a clear warning under § 29 ZPO/SZ, publication service was permissible when the husband failed to maintain a Swiss service address.
Fundamentação extraída
The prior order unambiguously required designation of a Swiss recipient for service throughout the proceedings; once the appointed Swiss lawyer withdrew, a new address had to be designated. The husband and his foreign counsel had to understand the consequences of non-compliance.
