Frequently Asked Questions

What is the maximum interest rate for a promissory note in South Dakota?
South Dakota does not impose a general statutory cap on interest rates for private written contracts. Parties have flexibility to agree on a rate, but courts may still void terms they find unconscionable or predatory.
Do I need a notary for a promissory note in South Dakota?
Notarization is not required in South Dakota for a promissory note to be legally valid. Notarizing it anyway is strongly recommended - it deters forgery claims, simplifies court enforcement, and makes the note self-authenticating as evidence. Having 1 witness is also recommended.
What happens if a borrower defaults on a promissory note in South Dakota?
Upon default, the lender may demand immediate repayment of the full outstanding balance, charge any default interest rate specified in the note, and file suit in South Dakota court. As a secured note, the lender may also seize and sell the collateral to recover the outstanding amount. Lenders have 6 years from the date of default to file a lawsuit under South Dakota's statute of limitations for written contracts.
What collateral can be used for a secured promissory note in South Dakota?
Common collateral for secured promissory notes includes real estate, vehicles, equipment, bank accounts, or valuable personal property. The collateral must be described in detail in the note - make, model, serial number, or legal property description depending on the asset type. The lender's right to seize and sell the collateral upon default must also be clearly stated. For real estate collateral, a separate deed of trust or mortgage is typically also required.
What is the difference between a secured and unsecured promissory note?
A secured promissory note is backed by collateral - if the borrower defaults, the lender can seize the collateral to recover the debt. An unsecured note relies solely on the borrower's promise to repay; the lender must sue and obtain a judgment to collect. Secured notes carry less risk for the lender and typically carry lower interest rates as a result.
