06 May Can I legally complete a real estate property purchase just through a properly made contract with the seller instead of through a Notary in Spain?
Yes, you can. Private contracts, as opposed to public contracts (the ones signed in front of Notaries) also have validity and completion force in what refers to any permissible condition they include and are perfectly binding for you and your seller.
However, according to the Spanish legal system these contracts have no legal effects for/against third parties not knowing that such contract exists, such as banks, creditors, tax authorities, claimants, etc. Bearing this in mind you would understand how important it is that a purchasing contract is made “public”, and in Spain this is only legally possible through a Notary’s “Escritura” jointly with the registry at the Property’s Registry of the town where the property is situated. By means of this Escritura and registry, there is no third party who can allege the contract has no effects for/against him.
