California County Clerks Offices
Select to the county where you will file your commission, oaths and bond to see instructions or contact information:
A notary public must file an oath of office and bond with the county clerk’s office in the county where their principal place of business is located. This must be done within 30 calendar days from the commencement date of the commission. This 30 day period cannot be extended.
Statutes provide for filing the oath and bond by mail. It should be noted that the county processes documents in chronological order, but not necessarily on the date received due to the volume of documents. The oath and bond may be submitted to the county clerk prior to the commencement date of the commission and must be filed no later than 30 calendar days after the commencement date of the commission.
It is recommended that the oath and bond be submitted in person to guarantee timely filing. (Government Code section 8213(a).) – SOS Website
