If there are no unusual problems, a typical California probate proceeding can be concluded in approximately seven to twelve months. Due to crowded court calendars, hearings are often held six to ten weeks after the initial probate petition is filed. After Letters of Administration are issued, there is a mandatory four-month creditor claim period. There may be other delays in getting a probate referee assigned, completing the inventory and appraisal, dealing with creditors, resolving tax issues, or will contests that could delay the probate for even longer periods.
