PROB §9103: (a) Upon petition by a creditor or the personal representative, the court may allow a claim to be filed after expiration of the time for filing a claim provided in Section 9100 if either of the follow

(a) Upon petition by a creditor or the personal representative, the court may allow a claim to be filed after expiration of the time for filing a claim provided in Section 9100 if either of the following conditions is satisfied: (1) The personal representative failed to send proper and timely notice of administration of the estate to the creditor, and that petition is filed within 60 days after the creditor has actual knowledge of the administration of the estate. (2) The creditor had no knowledge of the facts reasonably giving rise to the existence of the claim more than 30 days prior to the time for filing a claim as provided in Section 9100, and the petition is filed within 60 days after the creditor has actual knowledge of both of the following: (A) The existence of the facts reasonably giving rise to the existence of the claim. (B) The administration of the estate. (b) Notwithstanding subdivision (a), the court shall not allow a claim to be filed under this section after the court makes an order for final distribution of the estate. (c) The court may condition the claim on terms that are just and equitable, and may require the appointment or reappointment of a personal representative if necessary. The court may deny the creditor’s petition if a payment to general creditors has been made and it appears that the filing or establishment of the claim would cause or tend to cause unequal treatment among creditors. (d) Regardless of whether the claim is later established in whole or in part, payments otherwise properly made before a claim is filed under this section are not subject to the claim. Except to the extent provided in Section 9392 and subject to Section 9053, the personal representative or payee is not liable on account of the prior payment. Nothing in this subdivision limits the liability of a person who receives a preliminary distribution of property to restore to the estate an amount sufficient for payment of the distributee’s proper share of the claim, not exceeding the amount distributed. (e) Notice of hearing on the petition shall be given as provided in Section 1220. (f) Nothing in this section authorizes allowance or approval of a claim barred by, or extends the time provided in, Section 366.2 of the Code of Civil Procedure.
