Short answer. Yes. Under Article 1293 of the Civil Code, substituting a new debtor may be made even without the knowledge or against the will of the original debtor. The only indispensable consent is the creditor's — not yours. If the creditor agreed, the substitution is valid even though you were not consulted.
What the law says
Novation which consists in substituting a new debtor in the place of the original one, may be made even without the knowledge or against the will of the latter, but not without the consent of the creditor.

The original debtor's consent is not required
Article 1293 of the Civil Code draws a deliberate contrast: the substitution of a new debtor may be made even without the knowledge or against the will of the latter, but not without the consent of the creditor. Your knowledge and agreement are legally irrelevant to whether the substitution takes effect. The creditor's consent — which was given here — is the one condition the law makes non-negotiable. If the creditor has agreed to accept a different person as debtor in your place, the novation is valid whether or not you were informed.
Why the law is structured this way
The reason your consent is not required relates to who bears the credit risk. The creditor extended an obligation based on their assessment of the debtor. Only the creditor can decide whether a different person is an acceptable substitute — and only the creditor has an interest worth protecting when the debtor changes. The original debtor, once released, carries no ongoing exposure. If the new debtor fails to pay, the creditor cannot go back to the original debtor under a valid novation. The creditor's consent therefore protects the creditor; excluding the debtor's consent avoids giving the debtor a veto over their own release.
What this means for the new debtor's rights
Article 1293 also specifies that payment by the new debtor gives them certain rights. If the new debtor paid without your knowledge or against your will, they can recover from you only what their payment actually benefited you — not the full amount paid if that amount exceeded what you gained. Additionally, the new debtor who paid without your consent cannot compel the creditor to subrogate them in the creditor's rights — such as those arising from a mortgage, guaranty, or penalty. Paying to step into the creditor's secured position requires the original debtor's knowledge and cooperation.
Confirming you are fully released
If the creditor has accepted a new debtor in your place, the critical practical question is whether the original obligation was fully extinguished — or whether the creditor simply added a co-debtor without releasing you. Article 1293's novation requires that the new debtor replace the original one, not merely join the obligation. To confirm your release, review any document the creditor signed and ask whether it expressly discharges you. An ambiguous or informal agreement may not constitute a proper novation. A lawyer can review the arrangement and advise whether you are genuinely freed from the debt.
