n. a time stated in a contract in which a late payment or performance may be made without penalty. Often after the grace period ends without payment or performance by the person who is supposed to pay, the contract is suspended. Example: if a person does not pay his/her insurance payment (premium) by the stated deadline, he/she usually has a few days extra to pay before the absolute deadline. If the person does not pay by then, the insurance company cancels the contract, i.e. your insurance.
