A Notario Publico is appointed by the State. They can not advise and consult the parties to a real estate transaction as they could possibly be in a situation of conflict of interest. They can not function as your lawyer. Their job in this situation is to be neutral, as the notary is working for the buyer, the seller, and the government. Therefore it is advisable to hire a lawyer to represent your interests. The lawyer will ensure there is no human errors or omissions and that your property title is registered correctly, review the chain of ownership, ensure the seller has the right to sell, and verify that taxes and utilities have been paid in full.
Hire a law firm that will provide a Title Guaranty and ensure you receive a free and clear title.
