How does a secured party establish a security interest in real property (land)?

Secured parties must perfect a security interests in land by publicly filing notice of the security in accordance with state recording statutes. Generally, mortgages and deeds of trust must be publicly registered in a government office where the land is located. This is typically known as the recorder or register of deeds office. This recording method is deemed necessary to give notice of ownership rights and interests to those who are interested in purchasing or loaning money for or against the property.

Note: In addition to providing notice, registration (filing) of mortgages also establishes priority for repayment if multiple people loan or lend money secured by the property.
