Key legal question
Whether Art. 170 ZGB survives the death of a spouse and can still ground disclosure claims by the surviving spouse.
Extracted holding
As a rule, the marital disclosure duty ends with dissolution of the marriage by death; no special circumstances justified a post-death claim here.
Extracted reasoning
The court held that Art. 170 ZGB is a self-standing marital disclosure right, but after death it may continue only exceptionally. The appellant showed no applicable exception from the doctrine and no sufficient protected interest.
