Section 601 Of Chapter 1. General Provisions From California Probate Code >> Division 2. >> Part 14. >> Chapter 1.
601
. If the law existing at the time of the creation of a power of
appointment and the law existing at the time of the release or
exercise of the power of appointment or at the time of the assertion
of a right given by this part differ, the law existing at the time of
the release, exercise, or assertion of a right controls. Nothing in
this section makes invalid a power of appointment created before July
1, 1970, that was valid under the law in existence at the time it
was created.
