    (1)  The  formal validity, intrinsic validity, effect, interpretation,
  revocation or alteration of a testamentary disposition of real property,
  and the manner in which such property descends when not disposed  of  by
  will, are determined by the law of the jurisdiction in which the land is
  situated.
    (2)  The  intrinsic  validity,  effect,  revocation or alteration of a
  testamentary disposition of personal property, and the manner  in  which
  such  property  devolves when not disposed of by will, are determined by
  the law of the jurisdiction in  which  the  decedent  was  domiciled  at
  death.
    (c)  A will disposing of personal property, wherever situated, or real
  property situated in this state, made within or without this state by  a
  domiciliary or non-domiciliary thereof, is formally valid and admissible
  to  probate  in  this  state,  if  it  is  in  writing and signed by the
  testator, and otherwise executed and attested  in  accordance  with  the
  local law of:
    (1) This state;
    (2)  The  jurisdiction  in which the will was executed, at the time of
  execution; or
    (3) The jurisdiction in which the testator was  domiciled,  either  at
  the time of execution or of death.
    (d)  A  testamentary  disposition  of  personal property intrinsically
  valid under the law of  the  jurisdiction  in  which  the  testator  was
  domiciled  at  the time the will was executed shall not be affected by a
  subsequent change in the domicile of the testator to a  jurisdiction  by
  the law of which the disposition is intrinsically invalid.
    (e)  Interpretation of a testamentary disposition of personal property
  shall be made in accordance with the local law of  the  jurisdiction  in
  which the testator was domiciled at the time the will was executed.
    (f)  Whether  a  testamentary  disposition  of  personal  property  is
  effectively revoked  or  altered  by  the  provisions  of  a  subsequent
  testamentary  instrument  or  by  a  physical act to or upon the will by
  which the testamentary disposition was made is determined by the law  of
  the  jurisdiction  in  which  the testator was domiciled at the time the
  subsequent instrument was executed or the physical act performed.

    (g) Subject to paragraphs (d), (e) and (f),  the  intrinsic  validity,
  effect,  revocation or alteration of a testamentary disposition by which
  a power of appointment over personal  property  is  exercised,  and  the
  question of whether such power has been exercised at all, are determined
  by:
    (1)   In  the  case  of  a  presently  exercisable  general  power  of
  appointment, the law of the jurisdiction in  which  the  donee  of  such
  power was domiciled at the time of death.
    (2)  In the case of a general power of appointment exercisable by will
  alone or a special power of appointment:
    (A) If such power was created by will, the law of the jurisdiction  in
  which the donor of the power was domiciled at the time of death.
    (B)  If  such power was created by inter vivos disposition, the law of
  the jurisdiction which the donor of the power intended  to  govern  such
  disposition.
    (C)  If  the  donor  is  himself  the  donee  of  a  general  power of
  appointment exercisable by will alone, the law of  the  jurisdiction  in
  which the donor of the power was domiciled at the time of death.
    (3)  The  formal  validity of a will by which any power of appointment
  over personal property is exercised is  determined  in  accordance  with
  paragraph  (c) on the basis that the testator referred to therein is the
  donee of such power.
    (h) Whenever a testator, not domiciled in this state at  the  time  of
  death,  provides  in  his will that he elects to have the disposition of
  his property situated in this state governed by the laws of this  state,
  the  intrinsic  validity,  including  the  testator's  general capacity,
  effect, interpretation, revocation or alteration of any such disposition
  is determined by the local law of this state. The formal validity of the
  will, in such case, is determined in accordance with paragraph (c).
    (i) Notwithstanding the definition of "real property" in  subparagraph
  (a)  (1), whether an estate in, leasehold of, fixture, mortgage or other
  lien on land is real  property  governed  by  subparagraph  (b)  (1)  or
  personal  property governed by subparagraph (b) (2) is determined by the
  local law of the jurisdiction in which the land is situated.
