The role of the notary in Portugal differs greatly from their role in Belgium and the Netherlands. A notary in Portugal looks after the interests of the Portugese government. He checks if all taxes are paid at the transmission and he guarantees that the contract is legally correct. A notary in Portugal will not protect you from fraud. To prevent fraud it is best to hire an independent lawyer.
During the financially process, a notary in Portugal barely takes part. The purchase costs are directly paid to the selling real estate agent. However it is advised to pay through a client bankaccount of your lawyer.
