How much notice must a lender give before demanding repayment in Illinois?
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 Illinois, lenders have 10 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.
