Probating a will which exercises a power of appointment may mean more work than usual before jurisdiction is marked complete.
Pursuant to Uniform Rule 207.19(d):
In a probate proceeding where the will purports to exercise a power of appointment, a copy of the instrument creating the power of appointment must be furnished, and the petition for probate shall list those named in said instrument who are adversely affected by the probate of such will. Jurisdiction shall be acquired over such persons in the same manner as over distributees.
Estate planners should probably mull over this rule and its consequences before drafting a will purporting to exercise a power of appointment.
