What documents do you sign before the notarized deed when buying property in Spain?

When buying property in Spain, the first documents you sign often seem like a formality. Reservation, preliminary contract, deposits: for many investors, everything looks routine. In practice, however, every stage matters for the security of the transaction and your capital. In this article, I explain what you are really signing before the notarial deed, divided into the primary and secondary market, and what roles the individual parties play.

Primary market: contracts and roles of the parties

In the primary market, the developer and buyer play a key role, and the agent and lawyer are also involved in the process.

• The buyer signs a reservation agreement, and then a preliminary contract (most often the so-called contrato de arras or CPCV), which formalizes the commitment to purchase the property.

• The developer prepares the property for sale and is responsible for the complete documentation, required urban planning licenses, and payment schedule.
  
• The agent supports the organization of the transaction and advises on procedural matters but does not perform a full legal analysis.
  
• The lawyer conducts due diligence: verifies the title of ownership, absence of mortgage encumbrances, tax arrears and debts towards the community, urban planning licenses, and the consistency of data in the cadastre and property register.

When purchasing on the primary market, it is also worth understanding the legal protections that safeguard payments when buying off-plan properties.
We discuss this topic in more detail in the article: legal protections when buying off-plan property in Spain.

Secondary market: contracts and the role of the lawyer

The situation on the secondary market looks somewhat different:

• The buyer and seller sign a preliminary contract (most often the so-called contrato de arras), which regulates the terms of the sale.

• The agent supports the process of property search and organizes formalities, as well as advises which documents are worth consulting with a lawyer.
  
• The lawyer is responsible for comprehensive legal verification of the property: legal status, absence of encumbrances, taxes, debts towards the community, as well as preparing the preliminary contract and representing the client during the notarial deed.

Notary and lawyer: transaction security

The notary formalizes the deed and confirms the transfer of ownership, but it is the lawyer who protects your interests: verifies contracts, checks encumbrances, and represents you in all key transaction activities.

Micro-case: typical investor situations

We often assume that signing documents before the notarial deed is a formality and a “safe step.” In practice, these first documents build the transaction structure: safeguards, payment deadlines, and document verification are crucial.

Most investors discover that lack of document verification by a lawyer can lead to delays or unforeseen costs. This is the moment when the investor starts thinking in terms of a real estate portfolio rather than a single unit.

Checklist: how to prepare for the notarial deed

Before the deed, make sure that:

• the reservation and deposits are properly secured,
  
• the preliminary contract includes key conditions and the possibility of withdrawal,
  
• the developer’s or seller’s documentation is complete and correct,
  
• the lawyer verifies documents and conducts due diligence,
  
• the agent supports the organization of the transaction and advises during the preparation of documents.
  

Summary – key conclusions

Signing documents before the notarial deed does not mean the purchase is finished but builds the structure of the entire transaction. The differences between the primary and secondary market are significant, and the responsibility of each party: buyer, seller/developer, agent, and lawyer, determines the investment’s security.

The first signatures do not buy the property but give you control and certainty in the next stages.
