(a) Except as provided in subdivision (b), in satisfying a share provided by this chapter: (1) The share will first be taken from the decedent’s estate not disposed of by will or trust, if any. (2) If that is not sufficient, so much as may be necessary to satisfy the share shall be taken from all beneficiaries of decedent’s testamentary instruments in proportion to the value they may respectively receive. The proportion of each beneficiary’s share that may be taken pursuant to this subdivision shall be determined based on values as of the date of the decedent’s death. (b) If the obvious intention of the decedent in relation to some specific gift or devise or other provision of a testamentary instrument would be defeated by the application of subdivision (a), the specific devise or gift or provision of a testamentary instrument may be exempted from the apportionment under subdivision (a), and a different apportionment, consistent with the intention of the decedent, may be adopted.
