(1) Where a person entitled to inherit a compulsory share who becomes an heir has been limited by the designation of a reversionary heir, the appointment of an executor, or a direction concerning the partitioning of the estate, or where they have been charged with a legacy or a testamentary burden, they may claim their compulsory share if they disclaim their share of the inheritance; the period for filing a disclaimer does not commence until after the person entitled to a compulsory share has obtained knowledge of the limitation or charge.
(2) If the person entitled to a compulsory share has been appointed a reversionary heir, this is equivalent to a limitation of the appointment of an heir.
