Frequently Asked Questions
What is the maximum interest rate for a promissory note in Missouri?
Missouri caps interest at 10% maximum. Charging above the legal limit is usury - in Missouri, the penalty is: forfeiture of all interest; double penalty if willful. Always confirm the current rate with an attorney, as usury laws can change.
Do I need a notary for a promissory note in Missouri?
Notarization is not required in Missouri 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 Missouri?
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 Missouri court. Lenders have 10 years from the date of default to file a lawsuit under Missouri's statute of limitations for written contracts.
Is an unsecured promissory note enforceable in Missouri?
Yes. An unsecured promissory note is a legally enforceable contract in Missouri even without collateral. If the borrower defaults, the lender can sue in Missouri court and obtain a judgment, which can be used to garnish wages or bank accounts. Lenders have 10 years to file suit.
Is a promissory note the same as an IOU?
No. An IOU is an informal acknowledgment of a debt - it typically lacks repayment terms, interest rates, and default provisions. A promissory note is a formal legal contract with specific terms including the loan amount, interest rate, repayment schedule, and consequences of default. Promissory notes are far more enforceable in court than informal IOUs.
Is a promissory note legally binding in Missouri?
Yes. A properly executed promissory note is an enforceable contract in Missouri. It must identify both parties, state the loan amount and repayment terms, and be signed by the borrower. Lenders have 10 years to pursue legal action to collect on a defaulted note.
What interest rate is legal for a Missouri promissory note?
Missouri allows private parties to agree to any interest rate in a written contract - there is no general usury cap for written agreements between adults (Mo. Rev. Stat. §408.020). If no rate is specified, 9% per year applies as the default. Consumer loans are subject to specific licensing requirements and rate limits under Missouri's consumer lending laws. Missouri's 5-year statute of limitations applies to written promissory notes. Criminal usury charges can apply for unconscionable rates.
