GC-335: Capacity Assessment, CA Conservatorship

In a California probate conservatorship, this declaration records a clinician's capacity assessment of the proposed conservatee and submits it to the court under oath. It covers general physical and mental health, deficits in specific mental functions, and, as the petitioner requests, capacity to consent to specified or general medical treatment, a secured-perimeter dementia facility, or dementia medications.

Who completes it

The petitioner completes items 1 and 2, checking which capacity questions to answer and identifying the person. A California-licensed physician or licensed psychologist completes the rest and signs under penalty of perjury; no notary is needed.

Submitting and payment

How to submit it
Return the completed declaration to the petitioner or attorney, who files it in the court's confidential folder before the hearing. Secure or destroy your copy of the petition rather than sending it to the court.

  • Item 19 can refer to the optional Everyday Activities Attachment (GC-335A) for detail on daily living and instrumental activities.
  • Retitled and restructured effective January 1, 2025, replacing the Capacity Declaration. Form GC-334, an ex parte order, lets the clinician release information for the assessment.

Frequently asked questions

Who can complete GC-335?

A California-licensed physician, or a California-licensed psychologist practicing within the scope of the license. The form asks how long you have practiced, whether the person is your patient, how long you have known them, and the date and length of your most recent examination.

Which capacity questions does the clinician answer on GC-335?

Always Parts I and II on physical health, mental health and mental functioning. In Part III, only the items the petitioner checks in item 1: consent to specified treatment, to medical treatment generally, to a secured-perimeter dementia facility, or to dementia medications.

Is GC-335 confidential?

Yes. It is filed in the court's confidential folder. The petitioner gives the clinician a copy of the petition for reference but must not attach the Confidential Supplemental Information form (GC-312), and the clinician should secure or destroy that copy afterward.
