Questão jurídica principal
Whether the parties concluded a brokerage contract for the land sale.
Decisão extraída
The appellant did not prove that the respondent entered into a brokerage contract with him, expressly or by conclusive conduct.
Fundamentação extraída
A brokerage contract requires clear recognition by the client that the intermediary acts as broker. The correspondence showed only that a commission was mentioned and economically to be included in the purchase price; this did not show that the respondent was the contractual principal obliged to pay brokerage fees.
