As used in this section and sections 2807 to 2809:

    (a) "Disposition or appointment of property" includes, but is not limited to, a transfer of an item of property or another benefit to a beneficiary designated in a governing instrument.

    (b) "Divorce or annulment" means a divorce or annulment, or a dissolution or declaration of invalidity of a marriage, that would exclude the spouse as a surviving spouse within the meaning of section 2801. A decree of separation that does not terminate the decedent's marriage is not a divorce for purposes of this section and sections 2807 to 2809.

    (e) "Relative of the divorced individual's former spouse" means an individual who is related to the divorced individual's former spouse by blood, adoption, or affinity and who, after the divorce or annulment, is not related to the divorced individual by blood, adoption, or affinity.

    (f) "Revocable" means, with respect to a disposition, appointment, provision, or nomination, one under which the divorced individual, at the time of the divorce or annulment, was alone empowered, by law or under the governing instrument, to cancel the designation in favor of the individual's former spouse or former spouse's relative, whether or not the divorced individual was then empowered to designate himself or herself in place of the individual's former spouse or in place of the individual's former spouse's relative and whether or not the divorced individual then had the capacity to exercise the power.
