A South Dakota promissory note is a legally binding document that relays the terms whereby one party loans funds to another. The terms will include the start date of the loan, the principal sum (the amount of money lent), interest rate, repayment schedule, and (if applicable) late fees or collateral. A co-signer may be required to sign the contract to guarantee payment in the event that the borrower is unable to fulfill the contract. Although the document isn’t officially recorded, it may be used as evidence if legal action is required to enforce the agreement.
