Key legal question
Whether the daughters were entitled to request clarification of their parents' divorce judgment under Art. 334 ZPO.
Extracted holding
No. A request for clarification may be filed only by the parties, intervening parties, or successors; the daughters were neither.
Extracted reasoning
The court held that third parties lack standing under Art. 334 ZPO. A child-benefit clause in a convention may be a contract in favor of a third party, but this does not make the children parties, interveners, or successors in the divorce proceedings.
