Commercial Code 3505.

  3505.  (a) The following are admissible as evidence and create a presumption of dishonor and of any notice of dishonor stated:
   (1) A document regular in form as provided in subdivision (b) which purports to be a protest.
   (2) A purported stamp or writing of the drawee, payor bank, or presenting bank on or accompanying the instrument stating that acceptance or payment has been refused unless reasons for the refusal are stated and the reasons are not consistent with dishonor.
   (3) A book or record of the drawee, payor bank, or collecting bank, kept in the usual course of business that shows dishonor, even if there is no evidence of who made the entry.
   (b) A protest is a certificate of dishonor made by a United States consul or vice consul, or a notary public during the course and scope of employment with a financial institution or other person authorized to administer oaths by the laws of any other state, government, or country in the place where dishonor occurs. It may be made upon information satisfactory to that person. The protest shall identify the instrument and certify either that presentment has been made or, if not made, the reason why it was not made, and that the instrument has been dishonored by nonacceptance or nonpayment. The protest may also certify that notice of dishonor has been given to some or all parties.
