California parents who keep contents of their estate plans confidential aren't doing heirs any favors. Children can be disappointed, and sometimes angered to the point of litigation, by making assumptions about inheritances or roles as fiduciaries.
This question can only be answered by you as a testator, the will creator. The decision to designate a spouse or other relative as the executor of your estate depends on the qualities, abilities and willingness of the family member.
The word "executor" sounds like a title that could enhance a resume. In fact, a person who can handle the responsibilities of a California executor is probably well qualified for many jobs. Estate administrators known as fiduciaries have immense responsibility to a decedent, beneficiaries and probate court.
