When is a survey required to be filed in the County Clerk's land records in Oklahoma?

A survey must be filed in the County Clerk's land records in Oklahoma when it pertains to Plats/Subdivisions, making it crucial for maintaining official records regarding land use and developments. This requirement ensures that any new subdivisions or significant alterations to existing plots are properly documented, providing public access to this information, which is essential for legal clarity and facilitating transactions in real estate.

Filing these surveys not only helps to maintain the integrity of property boundaries but also assists in planning, zoning, and adherence to local regulations. The filing of subdivisions as an official record plays a vital role in the management of land development and is a critical element of Oklahoma's land surveying practice.

The other options do not accurately reflect the requirements set by Oklahoma law: not all surveys are mandated to be filed, the necessity for filing does not automatically trigger with a change in property ownership, and the assertion that no surveys ever need to be filed contradicts the regulations governing land records.
