(3) This paragraph shall not apply to a beneficiary designation, will
or trust that manifests an intent that a contrary rule shall apply.
(b) The executor, trustee or other interested person under a

such proceeding, extrinsic evidence may be admitted to establish the
decedent's intent.

following the day on which the chapter of the laws of two thousand
eleven which amended this paragraph became a law, whichever date is
later, and not at any time thereafter. Notwithstanding the foregoing,
the time to commence such a proceeding may be extended, in the
discretion of the court, on a petition showing reasonable cause and on
notice to such persons and in such manner as the court may direct.
