(a) Upon the expiration of five years after the date of entry of judgment in any proceeding pursuant to this chapter, or upon the expiration of five years after completion of notice by publication in an escheat action taken pursuant toSection 1415, the property covered by that proceeding or action shall permanently escheat to the state, except as provided in subdivision (b).

(b) Infants and persons of unsound mind shall have the right to appear and claim such property as provided in this title if born before the expiration of the five-year period; but it shall be presumed that there are no infants nor persons of unsound mind who are or will be entitled to claim this property unless and until they appear and claim the property as provided in this title. This presumption shall be conclusive in favor of any purchaser in good faith and for a valuable consideration from the state and everyone subsequently claiming under him or her, saving however, to infants and persons of unsound mind the right of recourse to the proceeds of any sale or other disposition of any such property by the state and as herein provided.

The named beneficiary or, if a court has rendered a judgment that the named beneficiary is dead, the blood relative of the named beneficiary shall be entitled to immediate payment upon this claim. If a court has not rendered a judgment that the named beneficiary is dead, payment of the claim of a blood relative of the named beneficiary shall be made on the day before the expiration of the five-year period described in this section. This subdivision shall not apply to authorize a claim by any person, including any issue or blood relative of that person, whose interest or inheritance was specifically restricted or barred by a provision in the donating or transferring instrument.
