If we accept the purpose that both attorneys and land surveyors apply principles of law toward ownership of real property, we must also accept the role of an assessor and staff as experts regarding the county Cadastre. The cadastral expert applies law, rules and common sense in forming an opinion of ownership and location of property boundaries for assessment purposes. This workshop adds to the body of knowledge of the participant in making the decision necessary for an accurate American Cadastre. This workshop focuses on the terminology and components of legal documents involved in the ownership and valuation of real property.
