Right of accretion

(1) If any of the instituted co-heirs dies before the testator or renounces the inheritance or becomes incapable or unworthy of receiving it, his share shall be added to the shares of the other instituted co-heirs, unless the testator has provided otherwise. (2) The heirs shall also be entitled to the right to accretion, if the legatees do not want or are unable to receive the legacy.
