Short answer. It is extinguished by merger, to the extent that you succeed to it. Article 1275 provides that the obligation is extinguished from the time the characters of creditor and debtor are merged in the same person. You cannot remain your own debtor, so the claim goes out rather than being paid.

Why the debt simply disappears
Article 1275 of the Civil Code needs only one sentence: The obligation is extinguished from the time the characters of creditor and debtor are merged in the same person. An obligation is a relation between two people, and it cannot survive when both ends land on the same one. Succession is the usual way this happens. You were your father's creditor; as his heir you step into his position on the other side of the same debt, and there is no longer anyone for you to demand payment from. The Code treats this as an extinguishment in its own right, not as a payment.
Merger only reaches your own share
This is the point that decides most family cases, because an only heir is rare. Article 1277 provides that confusion does not extinguish a joint obligation except as regards the share corresponding to the creditor or debtor in whom the two characters concur. Where you are one of four heirs, you have become the debtor of a quarter of what was owed to you, and only that quarter is wiped out by merger. The rest of the claim remains a claim, and it is asserted against the estate in the ordinary way alongside every other debt your father left.
It is not the same as being paid
The distinction has practical consequences. Extinguishment by merger means the claim is not satisfied out of estate funds ahead of distribution; it is netted against what you receive. If the estate is thin, an heir-creditor can find that the portion of his claim that merged has effectively been absorbed into an inheritance smaller than the debt. That is why the merged share and the surviving share need to be worked out early and recorded in the settlement documents, rather than left to be argued about when the property is being divided.
What proves the debt at this stage
Everything now turns on documents, because the person who could confirm the loan is gone. The promissory note, the acknowledgment receipt, the bank transfer or deposit slips, and any written demand made during his lifetime are what establish the claim against the estate. Bear in mind too that extinguishment of the principal obligation carries its accessories with it: Article 1276 provides that merger in the person of the principal debtor or creditor benefits the guarantors, so anyone who guaranteed the loan is released along with the part that merged.
