Does the debtor have the right to receive surplus proceeds after the auction of a property?After a property subject to fiduciary conveyance is auctioned, does the debtor have the right to receive any remaining balance? Yes. The law ensures the fiduciary debtor’s right to receive any amount that exceeds the total debt, provided that the auction was regularly conducted and that there is an actual economic surplus after full payment of the debt and statutory expenses.
This right derives directly from the principles of prohibition of unjust enrichment and contractual balance.
What is meant by “surplus proceeds” in fiduciary conveyance?
Surplus proceeds are the amount remaining after:
· full settlement of the debt;
· payment of contractual charges;
· deduction of procedural expenses;
· satisfaction of auction costs.
If the proceeds from the sale exceed the total amount due, the difference does not belong to the creditor and must be returned to the debtor.
May the fiduciary creditor retain the surplus amount?
No.
Undue retention of surplus proceeds constitutes unjust enrichment and violates the legal regime governing fiduciary conveyance.
The fiduciary creditor holds the asset under a resolutory title, not as an absolute owner entitled to the economic surplus. Its role is limited to satisfaction of the credit.
Is the surplus due even in an extrajudicial auction?
Yes.
The extrajudicial nature of the procedure does not eliminate the debtor’s substantive right. Fiduciary conveyance, even when carried out outside the courts, remains subject to:
· civil legislation;
· the principles of objective good faith;
· subsequent judicial review of legality.
The fiduciary creditor must render accounts and return any surplus, if it exists.
What happens when the property is sold for less than the debt?
In that case:
· there is no surplus to be returned;
· the creditor may not demand additional amounts from the debtor, unless expressly provided by law;
· the obligation is extinguished within the limits established by law.
The economic outcome risk of the auction is inherent to the fiduciary conveyance system.
Can failure to return the surplus give rise to liability?
Yes.
Failure to return surplus proceeds may result in:
· an obligation to refund the amount;
· application of monetary correction and interest;
· civil liability of the fiduciary creditor;
· judicial scrutiny of the procedure.
Transparency in calculating amounts is a legal duty of the creditor.
Must the debtor go to court to receive the surplus?
Ideally, no.
The surplus should be returned voluntarily. However, if the creditor resists, the debtor may seek judicial relief to:
· compel accounting/rendering of accounts;
· determine the correct amounts;
· obtain restitution of the surplus.
Judicial oversight functions as a mechanism to ensure balance and effectiveness of the substantive right.
Conclusion: the credit has limits—the surplus does not belong to the creditor
Fiduciary conveyance is a legitimate security instrument, but it does not authorize the improper appropriation of values.
The fiduciary creditor:
· is entitled to satisfaction of the credit;
· is not entitled to the economic surplus;
· must act with transparency and good faith.
In Real Estate Law, security is not a prize.
It is a legal limit on the exercise of credit.
