Question juridique clé
Whether the respondent could still invoke reduction of the testamentary annuity by objection after many years of unconditional payments.
Solution extraite
No. By paying the annuity for years with knowledge of the relevant facts, the respondent impliedly waived the reduction claim and could no longer raise it by objection.
Motifs extraits
Art. 533(3) ZGB allows the reduction claim to be raised by objection at any time while the heir possesses the estate, but waiver is possible after succession. Here the respondent knew the essential facts and nevertheless paid for about 20 years without reservation, which amounted to conclusive acknowledgment and a tacit waiver.
