Colorado Code
Part 2 - Creation, Revocation, and Amendment of Power of Appointment
§ 15-2.5-206. Power of the Donor to Revoke or Amend

Source: L. 2014: Entire article added, (HB 14-1353), ch. 209, p. 776, § 1, effective July 1, 2015.
The donor of a power of appointment has the authority to revoke or amend the power only to the extent the instrument creating the power is revocable by the donor or the donor reserves a power of revocation or amendment in the instrument creating the power.
For example, the donor's power to revoke or amend a revocable inter vivos trust carries with it the authority to revoke or amend any power of appointment created in the trust. However, to the extent an exercise of the power removes appointive property from the trust, the donor's authority to revoke or amend the power is eliminated, unless the donor expressly reserved authority to revoke or amend any transfer from the trust after the transfer is completed.
If an irrevocable inter vivos trust confers a presently exercisable power on someone who is not the settlor of the trust (the settlor being the donor of the power), the donor lacks authority to revoke or amend the power, except to the extent the donor reserved the authority to do so. If the donor did reserve the authority to revoke or amend the power, that authority is only effective until the powerholder irrevocably exercises the power.
If the same individual is both the donor and the powerholder, the donor in his or her capacity as powerholder can indirectly revoke or amend the power by a partial or total release of the power. See Section 402. After the power has been irrevocably exercised, however, the donor as donor is in no different position in regard to revoking or amending the exercise of the power than the donor would be if the donor and powerholder were different individuals.
The ability of an agent or guardian to revoke or amend a power of appointment on behalf of a principal or ward is determined by other law, such as the Uniform Power of Attorney Act or the Uniform Guardianship and Protective Proceedings Act.
Other law of the state may permit the reformation of an otherwise irrevocable instrument. See, for example, Uniform Probate Code § 2-805; Uniform Trust Code § 415.
The rule of this section is consistent with, and this Comment draws on, Restatement Third of Property: Wills and Other Donative Transfers § 18.2 and the accompanying Commentary.
