Section 11-A-3.1. When right to income begins and ends

(a)  An  income beneficiary is entitled to net income from the date on
  which the income interest begins. An income interest begins on the  date
  specified  in the terms of the trust or, if no date is specified, on the
  date an asset becomes subject to a trust or successive income interest.
    (b) An asset becomes subject to a trust:
    (1) on the date it is transferred to the trust in the case of an asset
  that is transferred to a trust during the transferor's life;
    (2) on the date of a testator's death in the case  of  an  asset  that
  becomes  subject  to  a  trust  by reason of a will, even if there is an
  intervening period of administration of the testator's estate; or
    (3) on the date of an individual's death in the case of an asset  that
  is  transferred  to  a  fiduciary  by  a  third  party  because  of  the
  individual's death.
    (c) An asset becomes subject to a successive income  interest  on  the
  day  after  the  preceding  income  interest  ends,  as determined under
  paragraph (d), even if there is an intervening period of  administration
  to wind up the preceding income interest.
    (d)  An  income  interest ends on the day before an income beneficiary
  dies or another terminating event occurs, or on the last day of a period
  during which there is no beneficiary to whom a  trustee  may  distribute
  income.
