What's the use of a real estate license with a notarial certificate?

In the process of buying and selling houses, you need to transfer the ownership of the real estate license to you. Notarial certificate can only prove that the buying and selling procedures are legal, and there is no substantial transfer of property rights. It still belongs to the original owner. When he has a property dispute, the court will of course enforce the property under his name. You are fooled into thinking that this way is cheaper with less money, and you don't want to think about how the state will set up two institutions to handle property transfer procedures, which is much cheaper to handle notarization procedures. Obviously, this will not work.
