(a) Except as provided in subsections (b) and (c) of this section and in § 18-3-105(a), the time of creation of a nonvested property interest or a power of appointment is determined under general principles of property law.
(b) For purposes of this chapter, if there is a person who alone can exercise a power created by a governing instrument to become the unqualified beneficial owner of (i) a nonvested property interest or (ii) a property interest subject to a power of appointment described in § 18-3-101(b) or § 18-3-101(c), the nonvested property interest or power of appointment is created when the power to become the unqualified beneficial owner terminates.
(c) For purposes of this chapter, a nonvested property interest or a power of appointment arising from a transfer of property to a previously funded trust or other existing property arrangement is created when the nonvested property interest or power of appointment in the original contribution was created.
(d) For purposes of this chapter, if a nongeneral power of appointment or a general testamentary power of appointment is used to create another nongeneral power of appointment or general testamentary power of appointment, the nonvested property interest or power of appointment created through the exercise of the other nongeneral power of appointment or general testamentary power of appointment is considered to have been created at the same time the first nongeneral power of appointment or general testamentary power of appointment was created.
