The scope of the donee's authority as to appointees and as to the time and manner of the appointment is unlimited except as the donor manifests a contrary intention.
The donee of a power of appointment which is presently exercisable, or of a postponed power which has become exercisable, can contract to make an appointment to the extent that the contract or the promised appointment does not confer a benefit upon a person who is not a permissible appointee under the power.
With respect to real property subject to a power of appointment, the interest of a donee and any appointee has priority as against creditors, purchasers, or encumbrancers of the real property, or as against a person having an estate in the real property, only from the time at which the instrument creating the power is duly recorded, but only if the creditors, purchasers, encumbrancers, and estate holders act in good faith or without notice. As against all other persons, this interest has priority from the time at which the instrument creating the power takes effect.
