The unnotified assignment of receivables can create a very practical problem: you have paid the original creditor and, only afterwards, another party claims to have become the owner of the same credit. The doubt is understandable: do you have to pay a second time? Is the assignment valid even if no one communicated it to you? And can you request compensation if the erroneous payment caused you expenses or other damages?
The central point is knowing what you knew when you paid. I will help you distinguish the validity of the assignment between the two creditors from its effectiveness towards you, to understand which documents matter and to recognize alternatives when conflicting requests arrive. The lack of a personal letter can be important, but it does not allow by itself to always give the same answer.
The assignment can be valid even without communication to the debtor
The credit can be transferred without your consent. In the assignment of receivables, the assignor is the original creditor, the assignee is who acquires the credit, and the assigned debtor is the person or business that must pay. The agreement between assignor and assignee can transfer the credit even if the debtor did not participate in the stipulation.
Your position remains protected by a specific rule, however. Article 1264 of the civil code links the effectiveness of the assignment towards the debtor to their acceptance or notification. The distinction does not mean that the assignee can never request payment before these acts: it serves above all to establish whether the payment made to the previous creditor is liberating, that is, whether it extinguishes the debt.
Validity of the assignment and liberating payment are therefore different questions. The Court of Cassation has clarified that the assignment is perfected with the agreement between assignor and assignee, while the discipline of Article 1264 protects the debtor with respect to payment executed to the wrong party. You can read the principle in the review of the Court of Cassation on ordinance no. 11436 of April 30, 2021.
It is not enough, therefore, to ask whether the assignment exists. At least four elements must be separated: the relationship from which the debt arises, the date of the assignment, the moment you became aware of it, and the day you arranged the payment. A bank transfer made before clear communication poses a different issue than an installment paid after having recognized in writing the new owner.
When payment to the original creditor releases you
Payment to the assignor can release you if you were in good faith. Article 1264 provides that, before notification, the debtor who pays the original creditor is not released only if the assignee proves that they already knew about the occurred assignment. It is not sufficient, therefore, to demonstrate that the assignment contract had been concluded: the debtor's knowledge at the precise moment of payment counts.
The date of payment is the first fact to reconstruct. A PEC received after the execution of the bank transfer does not demonstrate, by itself, that before the transfer you knew about the transfer. On the contrary, a previous unequivocal communication, referred to the contract or invoice concerned, can make paying the assignor again risky. Any responses sent, signed repayment plans, or declarations with which you recognized the new creditor are also relevant.
Knowledge does not always coincide with formal notification. If a notification is missing, the assignee can attempt to demonstrate that you were informed anyway. For this reason, the content, origin, and date of emails, PECs, letters, and other communications must be read carefully. A generic message, which does not identify the assigned relationship or does not clarify who can receive the payment, does not automatically solve the problem.
The receipt must be linkable to the requested debt. The bank transfer receipt, the remittance reason, an invoice, the contract, the file number, and bank statements serve to understand whether you actually paid the credit that the assignee is claiming. If you made partial payments, it is necessary to distinguish the quota already paid off from the residual: the fact that a previous installment was paid correctly does not authorize ignoring a subsequent transfer of credit.
Bank assignments and non-performing loans: additional rules
Block assignments in the banking sector follow special rules. Article 58 of the Consolidated Banking Act concerns, in the foreseen cases, assignments to banks of businesses, business branches, assets, and legal relationships identifiable in bulk. The advertising fulfillments provided for by the rule, namely registration in the business register and publication in the Official Gazette, produce towards the assigned debtors the effects indicated by Article 1264 of the civil code. The text of Article 58 is reported in legislative decree no. 208 of 2025 published on Normattiva.
The absence of an individual letter does not therefore render every bank assignment ineffective. One must first understand whether the operation truly falls within the special discipline and whether your relationship is identifiable among those transferred. Whoever requests payment must in any case explain which credit they claim, which balance they consider due, and whether they act as the owner of the credit or as an entity in charge of collection.
For non-performing loans, individual information also exists. Article 114.10 of the Consolidated Banking Act establishes that, in the purchase of non-performing loans in the cases regulated by the rule, the manager, bank, or intermediary in charge must individually inform the assigned debtor on paper or another durable medium after the assignment and before subsequent recovery actions. The information must also be provided when the debtor requests it. The discipline was introduced by legislative decree no. 116 of 2024.
The new creditor must link the request to the original relationship
The assignment does not transform an uncertain claim into an unquestionable debt. The assignee takes over the credit, but must indicate which contract, invoice, loan, or other relationship constitutes the source of the request. If the amount has already been paid, is calculated incorrectly, or derives from a contested relationship, these circumstances remain relevant even after the assignment.
Contestations on the original relationship do not automatically disappear. The Court of Cassation has specified, with reference to factoring, that the debtor can raise exceptions against the assignee regarding the existence, validity, and exact fulfillment of the relationship from which the credit arises. Facts that modify or extinguish the debt, instead, require particular attention to the moment when the debtor received notice of the assignment. The principle is illustrated in the civil review of the Court of Cassation of September 2025.
A written response must be precise, not merely negative. If you believe you have already paid, indicate the date, recipient, amount, and the document proving the payment. If you do not recognize the credit, clarify which elements you contest: the assignee's ownership, the traceability of the relationship, the requested balance, interest, or the original contract. Simply stating that you did not receive a notification can leave other decisive points unanswered.
Avoid hasty acknowledgments of debt. An explicit and unequivocal declaration addressed to the assignee can have relevant effects as acceptance of the assignment, without however exempting the acting party from proving the existence and original validity of the credit if the fundamental relationship is contested. The Court of Cassation recalled this limit in ordinance no. 25318 of September 16, 2025, reported in the same official civil review.
Restitution and compensation respond to different problems
A double payment does not automatically grant the right to compensation. If payment to the assignor is liberating, the assignee cannot demand the same performance from you again. If instead the payment does not release you because you already knew about the assignment, it may be necessary to address both the assignee's request and the recovery of the sum paid to whoever was no longer authorized to receive it.
Recovering a sum and obtaining damages are distinct remedies. Restitution concerns money paid without it being due to the recipient. Compensation, on the other hand, requires further damage, conduct attributable to a subject, and the link between that conduct and the prejudice suffered. Bank fees, costs incurred for a procedure, or consequences deriving from incorrect communications cannot be presumed: they must be identified and proven.
Interest and recovery expenses must be verified item by item. An assignment does not allow adding amounts lacking a contractual or legal basis, nor ignoring payments already made. Before paying a residual amount requested by the assignee, it is necessary to understand whether the sum includes principal, interest, any expenses, and payments already accounted for.
How to avoid a second payment when you receive conflicting requests
Do not pay twice just to close the doubt. A second payment can be difficult to recover and does not clarify, by itself, who was authorized to receive the performance. If the deadline is not imminent or the request is incomplete, it is preferable to request a written response that identifies the credit, the title of the assignment, the residual amount, and the entity authorized for collection.
Keep an essential chronology. Put in order the contract or invoices, communications received, PEC delivery receipts, bank statements, receipts, and accounting records. Chronology allows comparing what you knew before payment with what was communicated to you afterwards. If the payment was directed to an entity that the assignee had expressly commissioned to collect, that commission also becomes a decisive fact.
The choice changes if the debt is only partially paid. For sums already paid, the liberating effect of the payment is discussed; for future installments or amounts, the entity authorized to receive them must instead be clearly identified. When communications are contradictory, a documented contestation can prevent silence from being mistaken for acceptance of the entire request.
Frequently asked questions
Can I pay the original creditor if I have not received notification?
You can be released if you paid without knowing about the assignment. The absence of notification is an important element, but the assignee can prove that you were already informed with other elements. For future deadlines, it is not advisable to rely solely on previous practice: ask who is authorized to receive the payment and keep the response.
Who must prove that I knew about the assignment?
Proof of knowledge lies with the assignee. When payment to the assignor occurs before notification, it is the new creditor who must prove that the debtor already knew about the transfer. The dates of communications, delivery receipts, and any responses from the debtor therefore assume concrete relevance.
Is a simple email enough to oblige me to pay the new creditor?
Not only the medium used matters, but the clarity of the content. The message must be reliable and allow you to recognize the relationship concerned, the entity that purchased or manages the credit, and the economic request. A generic email does not automatically prove either the ownership of the credit or the balance due.
Can I contest the amount even after the assignment of the credit?
Yes, the assignment does not cancel contestations on the original relationship. You can assert, depending on the circumstances, payments already made, calculation errors, lack of performance, or other reasons affecting the existence and exact amount of the credit. However, it becomes important to indicate the facts and documents supporting the contestation.
Can I request compensation if I paid twice?
Compensation requires something more than just the duplication of payment. First, it must be clarified whether one of the sums must be returned and by which entity. Further damage can be requested only if you identify attributable conduct, actual prejudice, and the nexus between that conduct and the damage suffered.
The useful clarification before making a decision
The question is not just whether a letter arrived. We need to understand which credit was assigned, when you had effective knowledge of it, who you paid, and whether the entity asking for money today proves title and amount. If you have already made a payment or received mutually incompatible claims, you can contact me to examine the facts and documents that truly affect your position.
