Mandatory documents and procedures for selling a house in Spain

To sell a house in Spain it’s essential to comply with a series of procedures and provide specific documentation that guarantees the sale is carried out legally, safely and in accordance with current regulations.

These requirements don’t only respond to an administrative matter, but fulfill an essential function of legal protection for both the seller and the buyer.

Having all the documents to sell a property allows verification of the property’s ownership, its legal situation and compliance with tax and urban planning obligations, avoiding incidents during the sale and subsequent conflicts.

These are the reasons that support the importance of complying with procedures and attaching the required documentation:

• Guarantee the legality of the sale: documents such as the property deed and the simple note from the Property Registry allow verification that the seller is the legitimate owner of the property and that the property is free of charges, mortgages or encumbrances.

This verification is fundamental to protect the buyer and provide full legal security to the transaction.

• Transparency and trust between seller and buyer: having all the documentation for selling a flat in order—such as the energy certificate or the certificate of being up to date with payments to the homeowners’ association—generates an environment of trust during negotiation.

The buyer can verify that the property complies with legal requirements and that there are no outstanding debts, which facilitates the agreement and speeds up closing the transaction.

• Prevention of future legal and tax problems: the lack of any of the necessary documents to sell a house can lead to claims, sanctions or subsequent conflicts.

For example, not providing the last IBI receipt can generate conflicts about the distribution of taxes and selling without an energy certificate can result in fines from the Administration.

• Streamline notarial and registry procedures: Notaries and Registrars require specific documentation to formalize the sale.

Having all the documents to sell a flat from the beginning allows the signing of the public deed and registration in the Property Registry to be carried out without delays or additional requirements.

• Compliance with current regulations: the sale of real estate in Spain is subject to strict regulation.

Complying with the procedures to sell a flat and providing the required documentation is a guarantee that the transaction is carried out in accordance with the law, protecting both parties and providing stability to the property market.

What documents you need to sell a house in Spain

Before putting your property on the market, it’s essential to have complete documentation that supports the transaction. Having all the necessary papers allows you to manage the sale efficiently, comply with current regulations and convey security and confidence to buyers.

Below, we explain the essential documents and additional ones that can facilitate the sale:

Essential documents for selling a house in Spain

1. Property deed: this document certifies that you are the legal owner of the property. Without the deed, the sale cannot be formalised. It’s the basis of any transaction and allows the Notary and Property Registry to verify your ownership.
   
2. Energy certificate: mandatory since 2013, the energy certificate classifies the property’s energy efficiency. Its absence can hinder the sale and even generate administrative sanctions.
   
3. Last IBI receipt (Property Tax): certifies that you’re up to date with municipal payments. It can be obtained through the corresponding Town Hall’s website.
   
4. Residents’ association certificate: this document (issued by the Administrator and signed by the President) certifies that there are no debts with the community.
   
   It’s especially important in houses and properties that are part of communities to ensure the buyer doesn’t assume pending responsibilities.
   
5. Simple note from the Property Registry: shows the legal situation of the property, including ownership, charges and encumbrances.
   
   It’s normally requested a few days before signing, although the Notary will request and attach to the purchase deed an updated simple note on the day of the deed to guarantee the most recent information.

Additional recommended documents

Although not mandatory, these documents can speed up the sale and add value:

• Property plans: help buyers understand the layout and dimensions of the property.
• Installation certificates: certify compliance of electricity, gas and water installations.
• Habitability certificate: ensures the property meets minimum requirements to be inhabited.
• Mortgage cancellation deed / zero debt certificate: essential if the property was mortgaged and has already been paid off.
• Utility receipts: demonstrate that water, electricity and gas payments are up to date, avoiding surprises for the buyer.

Having all the documents to sell a house allows the Notary to check that everything is in order and to ensure the legality of the transaction.

Documents to bring to the Notary on the day of sale

The signing of the deed before a Notary is one of the most important moments when selling a house and requires all documentation to be in order.

Arriving at the Notary with all documents ready is one of the most important steps to sell a house and allows you to focus on formalizing the transaction, without worrying about pending procedures.

When formalizing the sale, the Notary must have the following documentation:

➨ Simple note from the Property Registry

➨ DNI or NIE of the seller and buyer

➨ Property deed of the property

➨ Energy certificate

➨ Last IBI receipt (Property Tax)

➨ Homeowners’ association certificate

Procedures after selling a property in Spain

Selling a house doesn’t end with signing the deed before a Notary. Once the sale is completed, you must comply with a series of procedures after selling a house to close the transaction definitively and avoid legal or tax problems.

After the sale, the seller must take care of certain taxes, among which stand out:

• Municipal capital gains tax: this tax levies the increase in land value from when it was acquired until the sale. It’s mandatory and must be managed with the corresponding Town Hall.
• IBI (Property Tax): unless otherwise agreed, it’s normal to agree that the seller must pay the proportional part of the IBI corresponding up to the sale date.
• Declaration of the sale to the Tax Office: you must include the transaction in the income tax return for the year of sale.

For example, if you sold a house in 2025, you must declare the capital gain obtained in the 2026 tax year.

In addition to taxes, it’s important to manage utilities to avoid inconveniences for the new owner:

➨ Provide the buyer with information about suppliers and contract numbers to guarantee a smooth transition.

➨ Cancel or transfer water, electricity, gas and other service contracts.

How the costs of selling a house are divided

When selling a property, it’s essential to know which expenses correspond to the seller and which to the buyer, to avoid surprises and properly plan the transaction.

The Civil Code, in its article 1455, establishes that:

“The expenses for granting the deed shall be borne by the seller, and those for the first copy and others subsequent to the sale shall be borne by the buyer, unless otherwise agreed.”

In practice, this means that, unless there’s a specific agreement between the parties, each assumes the costs provided by law.

Below, we detail how the main expenses of a sale are divided:
