Short answer. No. Article 1237 provides that whoever pays on behalf of the debtor without the knowledge or against the will of the latter cannot compel the creditor to subrogate him in his rights, such as those arising from a mortgage, guaranty or penalty. He gets a plain reimbursement claim instead.

What subrogation would have handed him

Article 1237 states it flatly: Whoever pays on behalf of the debtor without the knowledge or against the will of the latter, cannot compel the creditor to subrogate him in his rights, such as those arising from a mortgage, guaranty, or penalty. The rights listed are the whole point. Subrogation would have transferred not merely the debt but everything securing it. Article 1303 provides that subrogation transfers to the person subrogated the credit with all the rights appertaining to it, whether against the debtor or against third persons, be they guarantors or possessors of mortgages. A volunteer who pays behind your back does not acquire that arsenal.

What he gets instead

He acquires an ordinary personal claim, and a capped one. Article 1236 provides that whoever pays for another may demand from the debtor what he has paid, except that if he paid without the knowledge or against the will of the debtor, he can recover only insofar as the payment has been beneficial to the debtor. So he carries the burden of proving the benefit, and he sues as an unsecured creditor: no lien on your house, no guarantor to fall back on, no penalty clause to invoke. Against a debtor with little to seize, that is a materially weaker position than the one he displaced.

When subrogation does happen anyway

Subrogation is common enough; it simply needs a proper basis. Article 1302 presumes legal subrogation in three cases: when a creditor pays another creditor who is preferred, even without the debtor's knowledge; when a third person not interested in the obligation pays with the express or tacit approval of the debtor; and when a person interested in the fulfilment of the obligation pays even without the debtor's knowledge. That last case is the one people miss. A co-debtor, surety or owner of the mortgaged property is not a stranger to the obligation, and his payment can subrogate him whatever you thought of it at the time.

Which box the payer falls into

The answer usually turns on evidence already in your hands. Did you approve, even tacitly — a message, a request, or silence after being told what was about to happen? Did the payer have an interest of his own in the obligation, as co-maker, surety or third-party mortgagor? And has anything been signed since, because a deed of assignment or a conventional subrogation executed by the creditor changes the analysis entirely. Ask the creditor for whatever it issued when it accepted the money before conceding that anybody has stepped into its shoes.
