Conservatee, ability vs capacity.

Hi all,

I have a caseworker for a state program what wants my conservatee to sign paperwork on the appropriate lines that indicate my conservatee is the "Recipient" of the services. The caseworker's viewpoint is "We want them to sign if they have the physical capacity to sign, even if its just a mark."

From my understanding, my conservatee legally cannot sign the paperwork as I am his conservator and serve that function. My conservatee has the physical ability to sign, but does not have the mental capacity to understand the nuances of what my conervatee is signing and attesting to.

If it matters to the question, we live in California.

Any clarity would be very appreciated.
