A California Promissory Note is a legally binding document that outlines the terms of a loan between two parties. It serves as an agreement between a lender and a borrower, detailing the repayment of a loan. It includes the loan amount, the amount of interest to be paid, the repayment schedule, and any other terms agreed upon by the parties. There are several types of California Promissory Notes, including a Secured Note, Unsecured Note, Commercial Note, and Promissory Installment Note. A Secured Note is a loan that is backed by collateral, such as a car or house. An Unsecured Note is a loan that is not backed by any collateral, and repayment is based solely on the borrower's promise to pay. A Commercial Note is a loan specifically for business purposes. A Promissory Installment Note is a type of loan that requires the borrower to make regular payments over a certain period of time.
