(31)The contractual relationship between the credit servicer and the credit purchaser and the obligations of the credit servicer towards the credit purchaser should not be altered by the outsourcing of credit servicing activities to credit service providers. Credit servicers should be responsible for making sure that the outsourcing of their credit servicing activities to credit service providers does not result in undue operational risk, nor in non-compliance by the credit service provider with any requirements of Union or national law, nor restrict the capacity of a regulatory supervisor to perform its duty and safeguard borrower rights.
