The contract for purchase and sale is regulated by the Civil Code articles Art. 1793 through 1896. This contract is usually consensual, (it exist and has legal authority from the moment the buyer and seller agree what to sell and for how much) except in those cases where the law requires certain formalities. In the case of real estate, article 1801 of the Chilean Civil Code has established that the contract is not perfect or valid until the signing of a formal document called escritura pública. In order to get this document (which contains the contract itself) the text must be written in a certain format, in most cases prepared by an attorney. The draft prepared by the attorney must be transfered to an archive copy, usually a task for the Notary staff, and that copy is signed by the parties at the Notary's office. This formality does not imply just signing a document at the Notary. It is a special type of document that will become part of an Archive or Public Record at the Notary itself. At this point you just have a title. In order to be the actual owner of the property you must take a copy of the formalized contract and complete the ownership inscription at the Property Archive of the Registry. (Inscripción de Dominio en el Registro de Propiedad del Conservador de Bienes Raíces). That ownership inscription is the legal obligation to complete the transfer of property to your name. Until completed, you have simply bought the right to register as the legal owner.

After that long description of the legal procedure, confusing as it might be, the real question is: What do you need for a legal transfer of a property in Chile?

Well, like most things related to law, the devil is in the details.

What you must have to own real estate in Chile:

1. The formalized contract. (escritura pública otorgada ante Notario)
2. A copy of the formalized contract must be taken to the Registry for ownership inscription. (Inscripción de Dominio en el Registro de Propiedad del Conservador de Bienes Raíces).
3. A copy of that contract with a stamp from the Office of the Registry with the Number assigned on the Index Book (Repertorio), year of the Property Archive (Año del Registro de Propiedad), and number of that inscription in the year Archive. At this point you own the property.

Before signing the contract you must have:

1. The Title Report for the property (Estudio de Títulos). Make sure you have a good title, there are many problems and pitfalls with inscriptions, legal requirements, and eminent domain laws and regulations. This is specially common in rural areas. For this report we would highly recommend for you to hired your own attorney. Most lawyers are qualified, but better make sure they are experts on the issue. For the most part, real estate brokers have their own legal team, or they work in association with a lawyer. At some point this could be a clear case of conflict of interest. If there is any pitfalls, they may overlook them just to close the deal. A good title report is not an easy task, it takes time and expertise. As far as prices go, you have to have in mind that Chilean Attorneys are not as expensive as Americans. So for a little extra cash, you can double check everything is in order. Now, if you are buying with a loan from a Chilean Bank, they will take care of everything before approving the loan. In that case, you just have to rely on the bank's legal team. They are normally very good. Banks do not want you to have a bad title, on money they loaned you. The land is more theirs, than yours until you pay it.
2. If you have a tourist visa, work visa, or you are a foreign investor, and you do not have temporary or permanent residency in Chile, you must apply at the National Tax Office (Servicio de Impuestos Internos SII) for a RUT (Rol Único Tributario). This is just a number issued for tax purposes, required for all foreigners without legal residency in Chile for the purchase of stock, real estate or any acquisition that requires inscription and formalities in any type of public records. If you have residency, you will be issue a RUN or identity card number (Cédula Nacional para Extranjeros) and that same number will be used for tax purposes (to make it clear, in that case your RUN will be used as RUT also).
