On the basis of the Civil Code (Art. 509 CC et al.) claims (debt) can be transferred to the assets of a third party. The claim has the creditor’s property right, who may freely dispose of it.
The buyer together with the claim assumes all the powers and duties of the creditor. This means that the buyer of claims may require the debtor to pay only the amount that was owed to the vendor. The debtor has the right to a fair hearing and can raise an objection against the existence and value of claims towards the assignee, which was vested in him towards the assignor at the date of claims transfer.
