Caveat emptor

Under the doctrine of Caveat Emptor, the buyer could not recover from the seller for defects on the property that rendered the property unfit for ordinary purposes. The only exception was if the seller actively concealed latent defects. The modern trend in the US, however, is one of the Implied Warranty of Fitness that applies only to the sale of new residential housing by a builder-seller and the rule of Caveat Emptor applies to all other sale situations (i.e. homeowner to buyer).(See Stambovsky v. Ackley, 572 N.Y.S.2d 672 (N.Y. App. 1991)) Many other jurisdictions have provisions similar to this.

Before statutory law, the buyer had no warranty of the quality of goods. In many jurisdictions, the law now requires that goods must be of "merchantable quality". However, this implied warranty can be difficult to enforce, and may not apply to all products. Hence, buyers are still advised to be cautious.

In addition to the quality of the merchandise, this phrase also applies to the return policy. In most jurisdictions, there is no legal requirement for the vendor to provide a refund or exchange. In many cases, the vendor will not provide a refund but will provide a credit. In the case of software, movies and other copyrighted material many vendors will only do a direct exchange for another copy of the exact same title. Most stores require proof of purchase and impose time limits on exchanges or refunds; however, some larger chain stores will do exchanges or refunds at any time with or without proof of purchase.

Laidlaw v. Organ, a decision written in 1817 by Chief Justice John Marshall, is believed by scholars to have been the first U.S. Supreme Court case which laid down the rule of caveat emptor in U.S. law.

This phrase has given rise to many informal variations, such as caveat reader (properly expressed in Latin as caveat lector).

It is a counter to caveat emptor, and suggests that sellers too can be deceived in a market transaction. This forces the seller to take responsibility for the product, and discourages sellers from selling products of unreasonable quality.

In the landmark case of MacPherson v. Buick Motor Co. (1916), New York Court Appeals Judge Benjamin N. Cardozo established that privity of duty is no longer required in regards to a lawsuit for product liability against the seller. This case is predominantly regarded as the origin of caveat venditor as it pertains to modern tort law in US.
