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.

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.

What happens if a borrower misses an installment payment in South Dakota?
If the borrower misses a payment, the lender can charge any late fee stated in the note and, if the note includes an acceleration clause, demand the full remaining balance immediately.
