Key legal question
Whether the debtor proved extinction of the claimed debt by compensation
Extracted holding
No. The alleged compensating claim was not shown by an enforceable title or an unconditional admission by the creditor, and the proposed file production was irrelevant.
Extracted reasoning
Definitive discharge requires strict proof of extinction under Art. 81 LP. Compensation is only relevant if the counterclaim itself is enforceable or admitted without reservation. The requested evidence could not establish that condition.
