“Caveat emptor é uma expressão latina e significa – literalmente – o risco é do comprador. Outra forma de traduzir a expressão seria: Compre por sua própria conta e risco. A situação oposta é o Caveat venditor” (definicao da wikipedia )
A warning that notifies a buyer that the goods he or she is buying are “as is,” or subject to all defects
When a sale is subject to this warning the purchaser assumes the risk that the product might be either defective or unsuitable to his or her needs.
This rule is not designed to shield sellers who engage in Fraud or bad faith dealing by making false or misleading representations about the quality or condition of a particular product. It merely summarizes the concept that a purchaser must examine, judge, and test a product considered for purchase himself or herself.
The modern trend in laws protecting consumers, however, has minimized the importance of this rule. Although the buyer is still required to make a reasonable inspection of goods upon purchase, increased responsibilities have been placed upon the seller, and the doctrine of caveat venditor (Latin for “let the seller beware”) has become more prevalent. Generally, there is a legal presumption that a seller makes certain warranties unless the buyer and the seller agree otherwise. One such Warranty is the Implied Warranty of merchantability. If a person buys soap, for example, there is an implied warranty that it will clean; if a person buys skis, there is an implied warranty that they will be safe to use on the slopes.
A seller who is in the business of regularly selling a particular type of goods has still greater responsibilities in dealing with an average customer. A person purchasing antiques from an antique dealer, or jewelry from a jeweler, is justified in his or her reliance on the expertise of the seller.
If both the buyer and the seller are negotiating from equal bargaining positions, however, the doctrine of caveat emptor would apply.
