Caveat emptor

Caveat emptor /ˌkævɛɑːt ˈɛmptɔːr/ is Latin for "Let the buyer beware" (from caveat, "may he beware", a subjunctive form of cavēre, "to beware" + ēmptor, "buyer"). Generally, caveat emptor is the contract law principle that controls the sale of real property after the date of closing, but may also apply to sales of other goods. The phrase caveat emptor arises from the fact that buyers typically have less information about the good or service they are purchasing, while the seller has more information. The quality of this situation is known as 'information asymmetry'. Defects in the good or service may be hidden from the buyer, and only known to the seller.
