Short answer. No, not while any of the debt remains. Article 2089 makes a pledge or mortgage indivisible, so a debtor's heir who has paid only his share cannot have his portion of the property released until the whole debt is satisfied. A narrow exception applies where each thing secures a determinate part.
What the law says
A pledge or mortgage is indivisible, even though the debt may be divided among the successors in interest of the debtor or of the creditor. Therefore, the debtor's heir who has paid a part of the debt cannot ask for the proportionate extinguishment of the pledge or mortgage as long as the debt is not completely satisfied.

The security stays whole even when the debt splits
Inheritance can divide a debt among several heirs, but it does not divide the security that backs it. Article 2089 states this plainly: A pledge or mortgage is indivisible, even though the debt may be divided among the successors in interest of the debtor or of the creditor. Therefore, the debtor's heir who has paid a part of the debt cannot ask for the proportionate extinguishment of the pledge or mortgage as long as the debt is not completely satisfied. So paying your inherited share, on its own, does not carve your portion of the property out of the encumbrance.
Why partial payment does not release part
The logic is that the pledge or mortgage answers for the entire obligation, not for any single slice of it. The whole property stands as security for the whole debt, and it continues to do so until the last peso is paid. Allowing an heir to peel off his share of the collateral on paying his share of the debt would steadily erode the creditor's cover and defeat the very purpose of security. The debt is divisible among the successors; the lien over the thing is not, and it remains fully in place while any part of the debt is outstanding.
The exception for separately-secured portions
There is one situation where release can be partial. The article excepts the case where, there being several things given in mortgage or pledge, each one of them guarantees only a determinate portion of the credit. Where the parties expressly tied specific things to specific parts of the debt, the debtor gains a right to have a particular thing freed as the portion for which that thing is specially answerable is paid. This depends entirely on the parties having made that apportionment; without it, the ordinary rule of indivisibility governs and nothing is released early.
Check the document, then look to your co-heirs
Start with the mortgage or pledge instrument: does it assign specific things to specific portions of the debt? If it does, you may free the thing whose apportioned share you have paid. If it does not — the usual case — your payment does not unencumber your part, and the property remains fully bound until the entire debt is cleared. Your practical recourse then runs not against the creditor but among the heirs: having paid more than your ultimate share of the burden, you look to the co-heirs for contribution, while the collateral stays intact for the creditor.
