What does possession equal in terms of security interest?

In secured transactions, the principle of "possession equals automatic perfection" refers to the idea that when a secured party takes physical possession of collateral, their security interest is automatically perfected without the need for filing a financing statement. This concept is rooted in the Uniform Commercial Code (UCC), which provides that certain types of collateral, especially tangible goods, can achieve perfection through possession.

When the secured party possesses the collateral, it creates a visible claim to that property, ensuring that third parties are aware of the secured party’s interest. This automatic perfection is particularly useful in that it secures the creditor's interest without the formalities of filing, making it easier and quicker to protect their rights.

While temporary registration, evidence of ownership, and proof of sale address various aspects of property and transactions, they do not provide the same direct and immediate relationship to securing a perfection status as possession does in the context of secured transactions. Temporary registration refers to transitory legal status, evidence of ownership pertains to the documentation of ownership rights, and proof of sale indicates the completion of a transaction. None of these concepts directly equate to the automatic perfection conferred by possession in the realm of security interests.
