Short answer. By subrogation, the person who pays steps into your creditor's shoes. He takes over the credit with all the rights attached to it — against you as debtor and against third persons such as guarantors and holders of mortgages. He does not become a fresh creditor with new terms; he inherits the old ones.
What the law says
Subrogation transfers to the persons subrogated the credit with all the rights thereto appertaining, either against the debtor or against third person, be they guarantors or possessors of mortgages

The debt does not disappear — it changes hands
This is the part that shocks borrowers. A relative, an employer or a company pays off the bank, and the borrower assumes the obligation is settled. It is not. Subrogation transfers the credit, meaning the whole claim moves to the payer intact. He can demand payment from you, and he can do it on the same footing the bank had. What he cannot do is invent better terms for himself. If the original credit was already partly paid, or bore a particular interest rate, or was subject to a defence you could have raised against the bank, all of that travels with the credit.
The securities travel too
The Code is explicit that the transfer reaches third persons, be they guarantors or possessors of mortgages. So a co-maker, a surety, or a person whose land was mortgaged to secure the loan is now answerable to the new creditor rather than the old one. They do not get released simply because the original lender was paid off and walked away. This is exactly why guarantors should be told when a third party pays: their exposure has not ended, only moved. It is also why a payer who wants real protection should make sure the mortgage or surety documents are properly annotated and assigned, not merely assumed to follow.
Conventional subrogation can be negotiated
The article ends with a qualification: this is all subject to stipulation in a conventional subrogation. Subrogation can arise by operation of law in the situations the Code specifies, or it can be agreed. Where it is agreed, the parties may reshape what passes — releasing a guarantor, waiving a security, adjusting what the new creditor may enforce. That agreement, being a contract, needs the consent of the parties concerned, including the debtor in a conventional subrogation. If someone is about to pay your debt, this is the moment to put the terms in writing, because silence leaves you facing the full original claim.
What this does not settle
Article 1303 tells you the effect of subrogation, not when subrogation happens. Payment by a stranger does not always produce it; the Code distinguishes payment made with the debtor's approval, payment by someone with an interest in the obligation, and payment by a volunteer, and the consequences differ. Partial payment raises its own questions about how the old and new creditors rank. Prescription periods keep running on the original credit. None of that is decided here. If you are the payer, or the debtor being pursued by one, have a lawyer look at how the payment was actually made and documented before anyone concedes anything.
