Questione giuridica chiave
Whether the pledge granted to secure the son's debt constituted an asset waiver for EL purposes.
Decisione estratta
The pledge was a conditional waiver only; the waiver materialized when the bank enforced the pledge and claimed CHF 426,527.25 in April 2002.
Motivazione estratta
A third-party pledge without legal duty and without adequate counterperformance is a voluntary support measure, but it is not yet a waiver. Only when the pledged asset is actually realized and the claimant's assets are reduced does a compensable waiver arise.
