Does the Superior Court of California have any jurisdiction over the Estate of the deceased?

The superior court, although a court of general jurisdiction, when sitting as a probate court is a court of special and limited jurisdiction in that its jurisdiction is circumscribed in probate proceedings by the provisions of the statute conferring such jurisdiction and it may not competently proceed in a manner essentially different from that provided.
