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. Lenders have 6 years from the date of default to file a lawsuit under South Dakota's statute of limitations for written contracts.
How much notice must a lender give before demanding repayment in South Dakota?
A demand promissory note is due whenever the lender demands repayment - there is no fixed maturity date. The amount of notice required depends on what is written in the note itself; if no notice period is specified, repayment may be demanded immediately. Many demand notes include a minimum notice period (e.g., 30 days) as a courtesy term. In South Dakota, lenders have 6 years from when demand was first due to file suit.
What is the difference between a demand note and an installment note?
A demand promissory note has no fixed repayment schedule - the lender can call the loan at any time. An installment note has a set schedule of regular payments over a defined period. Demand notes are common for informal loans between family or friends, while installment notes are more common for larger, structured loans. Demand notes give lenders more flexibility but give borrowers less certainty.
