Legal Basics: Understanding Documentation in Real Estate Transactions

Buying property abroad is an exciting step, but also a logistical challenge. The key to a safe transaction isn’t just choosing a beautiful view from the terrace, but carefully reviewing the legal basics and documentation. Differences in legal systems (e.g., civil law vs. common law) can mean that the process we know in Poland will look completely different in Spain, Greece, or Dubai.

In this article, we explore the most important legal aspects you need to know before signing any contract.

1. Due Diligence, or Legal Audit

Before paying a deposit, it is necessary to conduct due diligence of the property. This verification process aims to rule out legal defects.

  • Title Deed: The most important document confirming the actual owner. It has different names in different countries (e.g., Escritura in Spain, Tapu in Turkey).

  • Land Registry: A register where you can check whether the property is not encumbered with mortgages, easements, or third-party claims.

  • Urban Planning Certificate: Confirms whether the building was legally constructed and whether the plot is zoned for residential development.

2. Key Documents in the Purchase Process

Understanding the documentation is the foundation of a safe real estate transaction. Here’s a list of the documents you’ll likely encounter:

Preliminary Agreement (Reservation Agreement / Promissory Contract)

Specifies the price, closing date, and deposit amount. It’s important that it includes exit clauses (e.g., if you don’t get a loan).

Tax Identification Number (e.g., NIE in Spain, AFM in Greece)

Most countries require foreigners to obtain a local tax number, without which they cannot sign a notarial deed or open a bank account.

Energy Performance Certificate

A mandatory document in most EU countries that provides information on the building’s operating costs in terms of energy consumption.

3. The Role of a Notary and a Lawyer Abroad

In Poland, the role of a notary is crucial and guarantees the security of transactions. In international transactions, this role varies:

  • Notary: Often acts as an impartial official who merely confirms the identity of the parties and the fact that the contract was concluded.

  • Independent lawyer (Abogado/Lawyer): In countries such as Spain or Cyprus, the presence of a lawyer is essential. They, not the notary, conduct a thorough review of the documentation and represent your interests.

  • Important tip: Never use a lawyer recommended solely by the developer or seller’s agent. Choose an independent expert who speaks your language or is fluent in English.

4. Pitfalls and a crucial documentation schedule

Lack of knowledge of local law can lead to costly mistakes, such as assuming hidden utility debts, purchasing a property without building permits, or complications related to inheritance law. To avoid this, you should collect the appropriate documents at specific stages of the process:

  • Extract from the Land and Mortgage Register Its main purpose is to finally confirm who owns the property and whether it is free from mortgages or third-party claims. This document must be checked first, before signing the preliminary contract.

  • Occupancy Permit (License of Occupancy) This document confirms that the building was constructed in accordance with the design and meets all technical and legal standards allowing for safe living. Verification of this certificate is necessary at the property handover stage.

  • Notarial Deed (Ownership Transfer Agreement) This is the document that concludes the entire process and constitutes official proof of the change of ownership under the law of the given country. It is signed in the presence of a notary at the end of the transaction after all payments have been made.

 

Summary

Understanding the legal basis for purchasing real estate abroad is a process that requires patience and expert support. Remember that documentation in a foreign language should always be translated by a sworn translator, and each document should be reviewed by a lawyer specializing in international law before signing.
