Creditor's responsibilities
The financial institution that buys a merchant's rights, notably the right to collect an item's price and credit charges, has the same obligations as the merchant who sold it this contract, e.g. you buy a car in instalments from a dealer who cedes the contract to a financing company. Should problems arise, you can take recourse against the financing company and the dealer.
If you borrow money to buy or lease an item, the law also stipulates that, should a problem arise, you can use the same means to defend yourself against a lender as you would against a merchant, salesperson or lessor, provided that they regularly do business together.
For example, to buy a car, you borrow from the bank branch close to the car dealer's, who says that he has referred his customers there many times. If the car you bought has a hidden defect and you are being sued by the bank because you stopped making your payments, you can oppose the fact that the car has a hidden defect as if the bank had sold it to you. You can also ask the courts to suspend payments on your loan until the final ruling is handed down.
