A UCC filing NH is a formal notice where a lender files with the secretary of state because they have a security interest against one of the properties. It provides notice that the investor has a stake, in the asset being used by you to fund the funding. The word “UCC filing” derives from the uniform commercial code. It was created to regulate the selling and leases of products. When the U.S. economy expanded, so did the need to control corporate transactions consistently. The UCC Filing NH was developed to standardize the mechanism of business dealings in states by providing more unity.
