court, or forum selection clauses. Where the disadvantaged party understood the improvident terms of the contract, the contract is unconscionable if they were so reliant on the advantaged party that they assented out of perceived necessity; meanwhile, where the disadvantaged party did not understand the improvident terms, "the focus is on whether they have been unduly disadvantaged by the terms they did not understand or appreciate". The intended purpose of the doctrine of unconscionability is "the protection of vulnerable persons in transactions with others". Nominate contracts Both Québec and the common law provinces and territories have enacted special rules for certain categories of contracts, specifying standard rules and conditions applying to these contracts. Contracts for the sale of goods Both the Civil Code of Québec and statutes in the common law provinces provide for certain standard rules in relation to contracts for the sale of goods. The purpose of these provisions is to ensure that parties to sale of goods contracts, particularly buyers, are protected from unfair conduct and defective products. While the purposes underlying both are similar, there are substantive differences in the provisions themselves. In Québec, a sales contract is defined as "a contract by which a person, the seller, transfers ownership of property to another person, the buyer, for a price in money". The code provides for a series of protections for both buyers and sellers, and defines the statutory obligations of each.
