Powers of appointment

An exercise of a general power of appointment created on or before October 21, 1942, shall be deemed a transfer of property by the individual possessing such power; but the failure to exercise such a power or the complete release of such a power shall not be deemed an exercise thereof. If a general power of appointment created on or before October 21, 1942, has been partially released so that it is no longer a general power of appointment, the subsequent exercise of such power shall not be deemed to be the exercise of a general power of appointment if— The exercise or release of a general power of appointment created after October 21, 1942, shall be deemed a transfer of property by the individual possessing such power. For purposes of this section, the term “general power of appointment” means a power which is exercisable in favor of the individual possessing the power (hereafter in this subsection referred to as the “possessor”), his estate, his creditors, or the creditors of his estate; except that— In the case of a power of appointment created after October 21, 1942, which is exercisable by the possessor only in conjunction with another person— If a power of appointment created after October 21, 1942, is exercised by creating another power of appointment which, under the applicable local law, can be validly exercised so as to postpone the vesting of any estate or interest in the property which was subject to the first power, or suspend the absolute ownership or power of alienation of such property, for a period ascertainable without regard to the date of the creation of the first power, such exercise of the first power shall, to the extent of the property subject to the second power, be deemed a transfer of property by the individual possessing such power. The lapse of a power of appointment created after October 21, 1942, during the life of the individual possessing the power shall be considered a release of such power. The rule of the preceding sentence shall apply with respect to the lapse of powers during any calendar year only to the extent that the property which could have been appointed by exercise of such lapsed powers exceeds in value the greater of the following amounts: For purposes of this section a power of appointment created by a will executed on or before October 21, 1942, shall be considered a power created on or before such date if the person executing such will dies before July 1, 1949, without having republished such will, by codicil or otherwise, after October 21, 1942.
