What Is Probate?
Probate is the court-supervised process of paying a deceased person’s debts and distributing their remaining property to heirs or beneficiaries. Conservatorships and guardianships are handled by the same Probate Division but serve a different purpose: a conservatorship lets the court appoint someone to manage the affairs of an adult who can’t manage them alone, while a guardianship gives someone legal authority over a minor child or their property. For a deeper explanation of the terminology involved, see our California probate terms glossary.
Getting Help With Forms: The Probate Facilitator and Conservatorship Workshop

If you’re representing yourself in a limited conservatorship or guardianship case involving a person only (no estate assets), the court’s Probate Facilitator, an attorney employed by the court, can help you understand and complete the required forms at no charge. Reach the Probate Facilitator by emailing probfac@contracosta.courts.ca.gov or leaving a voicemail at (925) 608-2066. Separately, anyone appointed as a conservator (except professional fiduciaries) is required to complete a Conservatorship Workshop covering the legal and financial responsibilities of the role; sign-up is mandatory in advance through the Contra Costa County Public Law Library at (925) 655-4627. For a broader look at what paperwork estates typically need, see our guide to required documents for an inheritance advance.

Frequently Asked Questions
Is there a separate courthouse for guardianships or conservatorships in Contra Costa County?
No. Unlike counties that split cases across multiple courthouses by case type, Contra Costa handles probate, guardianship, and conservatorship matters all in one place: the Wakefield Taylor Courthouse in Martinez.
Does the Probate Facilitator help with full estate administration?
No. The Probate Facilitator specifically assists with limited conservatorship or guardianship of a person only, cases with no estate assets involved. For estate administration, probate petitions, or anything involving property, you’ll generally need to work directly with the court clerk or an attorney rather than the facilitator.
What happens if I’m appointed a conservator but don’t complete the workshop?
The Conservatorship Workshop is a requirement, not optional guidance, for anyone appointed as conservator except professional fiduciaries. Sign-up must happen in advance through the Public Law Library, so it’s worth scheduling as soon as you’re aware you’ll be appointed rather than waiting until after the court order.
Can I file probate documents after the clerk’s office closes?
Yes, within limits. Contra Costa County courthouses have drop boxes, and any document deposited between 8:00am and 5:00pm is deemed filed that same day, even though the clerk’s windows themselves close at 4:00pm.
Where can I get free legal information about probate in Contra Costa County?
The Contra Costa County Public Law Library in Martinez, open 8:00am to 5:00pm on weekdays, offers legal research materials and workshop information, including the required Conservatorship Workshop sign-up, separate from the court clerk’s office itself.
