UCC-1 financing statements for business collateral are generally filed at the state level, through the Secretary of State, where the debtor is located, providing statewide lien coverage. However, this does not apply to all counties automatically for specific collateral types like real property, which often require separate, additional filings in the specific county records. Therefore, UCC liens are used for businesses but not often against persons, and especially when attempting to place a lien against real property.
