Everything you need to know about the deposit agreement
Signing a deposit agreement is one of the most important steps in a real estate transaction. This agreement not only allows a property to be reserved, but also establishes a legal commitment between buyer and seller. However, many people are unaware of its implications, the different types that exist or the legal consequences in case of breach. Below, we explain everything you need to know about this key document to ensure a safe and transparent transaction.
What is a deposit agreement and what does it include?
A deposit agreement is a private contract in which the buyer and seller formalize their intention to carry out a real estate transaction. In it, the buyer pays an amount as a deposit or advance. This sum serves to reserve the property and ensure that both parties will comply with the agreed terms.
Although it is not mandatory, this contract is highly recommended, as it acts as a legal safeguard if either party decides not to proceed with the transaction. In addition, notaries often use it as the basis for drafting the final purchase deed, so it is essential that it includes all relevant details of the agreement.
Among the key elements it should include are the personal details of the buyer and seller, a description of the property, the agreed final price, the deposit amount, the deadline to complete the transaction and the consequences of non-compliance. It is also important to specify the type of deposit agreement being signed, as this determines its legal effects.
For professionals working in finance, law or real estate, understanding concepts such as deposit agreements is part of the essential knowledge required to manage transactions safely and accurately. For this reason, specialized programs such as a Master in Finance can provide key tools to correctly interpret these agreements and their impact on financial planning.
Types of deposit agreements
There are three main types of deposit agreements, each with its own legal implications. The choice between them depends on the level of commitment desired by both parties and the specific conditions of the agreement.
- The confirmatory deposit agreement is the simplest. It serves as proof of the purchase commitment and the advance payment of part of the price. If either party breaches the agreement, the other may seek legal enforcement of the contract or claim compensation for damages.
- The penalty deposit agreement establishes a financial penalty in case of breach. Neither party can withdraw from the contract unilaterally unless explicitly agreed. The affected party may demand compliance with the agreement or the agreed penalty, and in some cases both.
- Finally, the withdrawal deposit agreement, also known as cancellation deposits, offers greater flexibility. It is regulated by Article 1454 of the Spanish Civil Code and allows either party to withdraw from the contract without justification. If the buyer withdraws, they lose the deposit. If the seller withdraws, they must return double the amount received.
This last type is the most common in Spain, as it provides flexibility in case of unforeseen circumstances or changes of mind.

How is a deposit agreement paid?
The deposit agreement is signed when the buyer and seller agree to formalize the transaction, but before signing the public deed. Its purpose is to reserve the property and remove it from the market, providing security for both parties while the necessary steps are completed, such as securing a mortgage or preparing legal documentation.
The deposit amount typically ranges between 5% and 15% of the total property price, with 10% being the most common figure. This amount is not an additional cost, but is deducted from the final price once the purchase is completed before a notary.
As for the payment method, it can be made via bank transfer, cheque or any other method agreed by both parties. It is essential that this payment is recorded in the contract and that traceable methods are used to avoid future disputes. Although it is a private document, the agreement is often signed in the presence of a real estate agent or a lawyer, adding an extra layer of security.
It is important to note that the deposit is generally non-refundable if the buyer decides not to proceed, unless the contract includes a termination clause for justified reasons (for example, if a mortgage application is denied). Therefore, if such a clause is not included, it is advisable to obtain an independent valuation and a technical inspection before signing.
Understanding the legal and financial framework of these agreements is crucial for those aiming to make strategic decisions in the financial field. Programs such as a Master in Financial Management help develop a comprehensive understanding of these transactions and their role in business management.
Expiry of the deposit agreement
The deposit agreement has a defined validity period, which must be clearly specified in the document. Typically, a period of 30 to 90 days is set to complete the purchase deed, although it can be extended by mutual agreement if delays occur. During this time, neither party can sell or purchase the property with third parties without breaching the agreement. If the deadline expires and the transaction has not been completed, the consequences will depend on the type of deposit agreement signed.
In the case of withdrawal deposits, the agreed penalty applies: the buyer forfeits the deposit or the seller must return double the amount. However, in confirmatory or penalty deposits, legal action may be taken to enforce the contract or claim compensation for damages.
For this reason, it is advisable to set realistic deadlines and include possible extensions in the agreement. It is also important to anticipate exceptional situations, such as mortgage rejection or legal issues with the property, through specific clauses that allow the contract to be terminated without excessive penalties.
In conclusion, the deposit agreement is a key tool in the process of buying and selling a property. It helps secure the transaction and clearly define its terms and consequences. Proper drafting, choosing the right type of deposit agreement and understanding its implications are essential to avoid conflicts and protect both parties’ interests. Seeking professional advice and carrying out a thorough property review before signing are crucial steps to ensure a safe transaction.
