The FTC's Trade Regulation Rule states a consumer has three business days to cancel a contract ( for over $25.00) signed at a private residence, motel, or other temporary location. This "cooling-off" period applies to cash as well as credit transactions. The seller is REQUIRED to provide the buyer "NOTICE OF CANCELLATION" papers at the time of the transaction. (FTC Rule 16-CRF-429 and IN Code 24-5-10-1 thru 18 and IN Uniform Credit Code 24-4.5-2-501 & 502)
Indiana Law requires that consumers be given a contract, orally or in writing, for any home improvement project costing $150.00 or more. (Indiana Law #24-5-11-4). Your BBB suggests contracts be in writing.
