For purposes of this subpart, the term “adverse party” means any person having a substantial beneficial interest in the trust which would be adversely affected by the exercise or nonexercise of the power which he possesses respecting the trust. A person having a general power of appointment over the trust property shall be deemed to have a beneficial interest in the trust.
A person shall be considered to have a power described in this subpart even though the exercise of the power is subject to a precedent giving of notice or takes effect only on the expiration of a certain period after the exercise of the power.
Notwithstanding any other provision of this subpart, this subpart shall apply only to the extent such application results in an amount (if any) being currently taken into account (directly or through 1 or more entities) under this chapter in computing the income of a citizen or resident of the United States or a domestic corporation.
In the case of any transfer directly or indirectly from a partnership or foreign corporation which the transferee treats as a gift or bequest, the Secretary may recharacterize such transfer in such circumstances as the Secretary determines to be appropriate to prevent the avoidance of the purposes of this subsection.
