What must a fixture filing include according to legal requirements?

A fixture filing must include identification of the real estate involved because this is a fundamental requirement in ensuring that the filing is enforceable against third parties and provides notice of the secured party's interest in the fixtures that are installed on the real property. In secured transactions, fixtures are considered part of the real estate to which they are affixed, and thus accurately identifying the real estate ensures that anyone searching property records can find the appropriate security interest in the real estate.

When a secured party files a fixture filing, they must comply with specific statutory requirements, which typically involve providing a description of the real estate, often by referencing the property’s legal description. This serves to protect the interests of the secured party while also clarifying the relationship between the secured collateral (the fixtures) and the underlying real property.

While identification of collateral location and market value might be relevant in other contexts, such as in the determination of priority among secured parties or for valuation purposes, they are not requisite components of a fixture filing itself. Therefore, the correct answer highlights the legal requirement to link the security interest to the real estate, solidifying the secured party's claims to the collateral.
