California Code, Business and Professions Code - BPC § 8768

If the matters appearing on the record of survey cannot be agreed upon by the licensed land surveyor or the registered civil engineer and the county surveyor within 10 working days after the licensed land surveyor or registered civil engineer resubmits and requests the record of survey be filed without further change, an explanation of the differences shall be noted on the map and it shall be presented by the county surveyor to the county recorder for filing, and the county recorder shall file the record of survey.  The licensed land surveyor or registered civil engineer filing the record of survey shall attempt to reach agreement with the county surveyor regarding the language for the explanation of the differences.  If they cannot agree on the language explaining the differences, then both shall add a notation on the record of survey explaining the differences.  The explanation of the differences shall be sufficiently specific to identify the factual basis for the difference.
