Key legal question
Whether important reasons justified granting the requested surname change under Art. 30(1) ZGB.
Extracted holding
Yes. The concrete circumstances, especially the long-standing factual use of the mother's surname and the child's age and personality interests, outweighed the public interest in name stability.
Extracted reasoning
The lower court gave excessive weight to the father-name continuity and insufficient weight to the factual name use and future personality continuity. The child had used the mother's name at school and socially for years, and returning to the official name at age 15 would be unreasonable.
