The next step will be the conclusion of a binding contract between the seller and the buyers, i.e. in Portuguese: CPCV (Contrato de Promessa de Compra e Venda). This agreement specifies what will be the subject of the transaction (description of the property and equipment), the agreed price and the deadline for concluding the final agreement. Signing the binding contract requires the buyers to pay a deposit to the seller. The deposit amount is usually 10% of the agreed price. As is the case with a deposit in Poland, if the buyers withdraw from the transaction, the deposit is forfeited to the seller. If the seller withdraws, he must return double the deposit to the buyer.
