Every distributor intending to avail himself or herself of the benefits of this article shall serve on the retailer or other commercial user by certified or registered mail, return receipt requested, or by personal service, within sixty days after completing the delivery of transportation fuel and record in the office of the county clerk and recorder of the county where the retailer or other commercial user is located, a statement containing a just and true account of the amount due to the distributor, after allowing all just credits and offsets, and containing a correct description of the taxes paid for the delivery of transportation fuel to the retailer or other commercial user and an affidavit of service or mailing of the statement. Any immaterial error or mistake in the account or description of the taxes paid does not invalidate the lien. The statement required by this section must include the name of the distributor, the name of the retailer or other commercial user, and the physical address of the retailer or other commercial user in the county where the retailer or other commercial user is located. The statement must also include the name and physical address of any other person, if any, against whose property the lien is filed and a description of the property to be charged with the lien.
