Questão jurídica principal
Whether the acknowledgements of debt under Art. 82 LP were unconditional and enforceable
Decisão extraída
No; the repayment clause made exigibility conditional on a subsequent agreement between the parties, so the creditor had to prove exigibility by additional documents.
Fundamentação extraída
A provisional debt-enforcement title requires a clear, unconditional, due monetary obligation. A clause making repayment and interest depend on agreement is a true condition, not merely a payment modality.
