The California Probate Code provides some support. Probate Code §8200 states that an individual in possession of a decedent’s original will must file it either with the county clerk or the person named as the primary executor of the decedent’s will, within thirty (30) days of learning of the decedent’s death.
Probate Code §12202 provides that the heirs of a decedent and beneficiaries named in a decedent’s will have a right to have the Personal Representative appear in court to explain the status of the probate administration and Probate Code section 10950 allows the beneficiaries to request the Personal Representative file an accounting that shows an inventory of the estate assets and the receipts, disbursements, and sales that have occurred since the probate proceeding began.
