Comparative law notes

"Vício redibitório" is a hidden defect that renders the goods improper for the use they were made for, or that reduces their value (sec. 441 et seq. of the Brazilian Civil Code)". As opposed to a hidden defect, a "vício redibitório" is a defect that the seller or service provider does not necessarily know about in advance.

Definitions of hidden defect

a fault that cannot be seen, that the seller or service provider knows about, and that cannot be easily discovered by close examination

If you are selling a house, and know of a hidden defect, you should seek legal advice to avoid liability down the road.
