Short answer. Yes. A debtor who pays his creditor before having knowledge of the assignment is released from the obligation. The new creditor cannot make you pay a second time; his remedy is against the person who took your money after selling the debt away.

What the law says

The debtor who, before having knowledge of the assignment, pays his creditor shall be released from the obligation.

The rule, and why it exists

The text is a single line: The debtor who, before having knowledge of the assignment, pays his creditor shall be released from the obligation. A debt can be sold or transferred without the debtor's consent — that is ordinary commerce, and it is how receivables, loans and instalment accounts change hands. But the debtor cannot be expected to guess that it has happened. The law therefore puts the risk on the parties who arranged the transfer: if they wanted payments redirected, informing the debtor was their job. Until that is done, paying the person you have always paid does exactly what paying a debt is supposed to do — it extinguishes it.

"Knowledge", not a particular kind of notice

The article turns on knowledge, and that cuts both ways. It means a formal notice is not the only thing that can bind you — if you actually knew the credit had been assigned, you cannot pay the old creditor and then plead the absence of a letter. Equally, it means an assignee who quietly bought your account and never told you cannot rely on the deed of assignment as though you had read it. Registration of the assignment between the assignor and assignee, or a note in someone else's files, is not knowledge on your part. The practical question is always the same: what did you know, and when could that be shown?

Proving the payment is the real battle

Nearly every dispute of this kind is decided on documents rather than on the rule itself. Keep the official receipt, the bank transfer confirmation, the deposit slip naming the account you paid into, and the message thread in which the old creditor gave you those payment instructions. Dates matter more than anything: the date of your payment against the date you were told of the transfer. If a collection agency or a new lender is now demanding the same amount, ask them in writing for a copy of the assignment and the date it was made, and do not pay anything on account while the position is unclear — a partial payment to the new claimant is easily read as an acknowledgement.

The limits of this protection

The article covers payments made before knowledge. Instalments falling due after you have been properly informed must go to the assignee, and continuing to pay the old creditor out of habit or loyalty will not be excused. Nor does the provision fix the parties' own quarrel: the assignee who was deprived of the payment still has a claim against the assignor who collected it, and that fight is not yours. Finally, being released from the amount you paid is not the same as being released from the whole debt — anything genuinely still outstanding remains owing to whoever now holds the credit. If you are being pursued for money you have already paid, gather the proofs and take advice before the demand turns into a case.
