Formation and validity

Nominate contracts in civil law jurisdictions and contracts subject to the United Nations Convention on Contracts for the International Sale of Goods (CISG) are subject to terms implied by the appropriate civil or commercial code or by the convention, respectively. Many civil law jurisdictions impose a legal duty of good faith which extends to the negotiation as well as performance of contracts. Under the CISG, a variety of terms implied by law are prescribed for contracts involving the international sale of goods. Generally, the goods must be of the quality, quantity, and description required by the contract, be suitably packaged and fit for purpose. The seller is obliged to deliver goods that are not subject to claims from a third party for infringement of industrial or intellectual property rights in the State where the goods are to be sold. The buyer is obliged to promptly examine the goods and, subject to some qualifications, must advise the seller of any lack of conformity within "a reasonable time" and no later than within two years of receipt.
