In the state of Arizona how many days does a person have to legally cancel a written and signed contract when not done in the buyer's home?

You have three business days to cancel a contract if: The sale was solicited in the consumer's home; or A gift was offered for attending a sales presentation that led to the contract; or A consumer's primary home is used as security and the loan is not used to purchase or construct the home. Otherwise, a signed contract - for a car, an item or a service - is legal and binding in all 50 states in the U.S.
