Questão jurídica principal
Whether the claimant had active standing to sue for the brokerage fee
Decisão extraída
The claimant had active standing because she signed the brokerage contract; the alleged assignment of the claim was not proven.
Fundamentação extraída
The defendant's evidence, including an email referring to a transfer of the contract, was insufficient and the contrary allegation was contested; the defendant bore the burden of proving that the claimant was no longer the creditor.
