Which document is essential for proving ownership of a property?

A certificate of title is essential for proving ownership of a property because it serves as a formal document that certifies the ownership of real estate. It outlines the legal rights tied to the property and confirms that the named individual or entity is the rightful owner as per public records. This document is crucial in transactions involving real estate, as it provides clarity on ownership and any claims or encumbrances that may exist against the property.

In contrast, other options do not serve the same purpose. A lease agreement primarily establishes the terms under which a property may be rented but does not indicate ownership. A title insurance policy provides protection against claims or losses due to defects in the title but is not a proof of ownership itself. An easement agreement grants specific usage rights over a property but does not pertain to ownership rights. Thus, the certificate of title is the definitive document for establishing and proving property ownership.
