A Louisiana Financing Statement Additional Party (LISA) is a document used to register a security interest in personal property in the state of Louisiana. It is typically used when someone is taking out a loan against a motor vehicle, boat, or other personal property. The LISA must be filed with the Louisiana Secretary of State in order to protect the lien holder's interest in the collateral. There are two types of Louisiana Financing Statement Additional Parties: the Debtor and the Secured Party. The Debtor is the person taking out the loan and the Secured Party is the person/entity providing the loan. The LISA must list the Debtor and Secured Party, as well as information about the collateral being used.
