Earnest Money Contract: what it is, what it's for, and types

June 30, 2026

In Spain, an essential legal instrument for agreeing to the purchase and sale of a house is the earnest money contract. Here we will explain what it consists of, what this legal instrument must stipulate, how it works, examples of earnest money contracts that exist, etc.

We will also address what distinguishes this agreement from a reservation agreement, why it is mandatory, where and how payment is made, and its duration. So be sure to read until the end; you're sure to find it interesting.

What is this contract and what is its purpose?

In short, it is a private agreement made by two parties interested in negotiating a subsidized housing unit or any other property. It's a type of preliminary commitment prior to the specific signing of the purchase and sale, where one party pays the other a percentage of the agreed amount. 

This agreement is entered into for several reasons, such as:

  • The buyer is applying for financing from a financial institution.
  • The seller must pay off the mortgage, terminate a rental agreement, or register a document to hold title to the property. 
  • Because it is a new build house and construction has not finished. 

How do earnest money contracts work?

From what has been explained, we can infer that this housing reservation agreement operates to protect those who are negotiating. The buyer guarantees that they will not sell the property to third parties. The seller is protected against the buyer's withdrawal, retaining the earnest money as compensation for any inconvenience or damages that may have been caused.

Types of Earnest Money Contracts

Those who are negotiating should know that there are several types of earnest money agreements, and each has its own characteristics and different legal implications.

Depending on your case, you should consult which of these three types suits your situation.

Confirming Earnest Money

Its purpose is to reaffirm the parties' commitment to finalize the purchase-sale negotiation, thus representing an advance payment of the agreed price. This agreement is made exclusively when there is a firm conviction to proceed with the negotiation, and neither party can unilaterally withdraw from it. 

Penalty Earnest Money

This agreement aims to establish a financial penalty for non-compliance by the negotiators, implementing different legal consequences for whoever withdraws from the purchase-sale. If the buyer withdraws, they will lose the amount advanced, and if the seller fails to fulfill the agreement, they will refund the amount received plus an agreed-upon sum.

Penitential Earnest Money or Right to Withdraw

This is the most flexible agreement and allows either negotiator to unilaterally withdraw from the pact if they deem it appropriate for their interests. It is common for negotiators or parties to agree on an amount as a penalty in the event of not wishing to continue with the negotiation.

Differences or discrepancies between an earnest money agreement and a reservation agreement

Expert professionals agree that the discrepancy lies in: 

The legal effects 

They are for the negotiators, should the need arise to revoke the contract. 

Earnest money is regulated 

Specifically contained in the Civil Code

Reservation agreements are not 

They are definitely not provided for in the Civil Code.

The reservation agreement is binding 

They must comply, unless they have agreed otherwise regarding rescission.

What should an earnest money agreement include?

It is worth noting that an earnest money agreement should include, among other requirements, the following:

  • Parties' details: names, surnames, ID number (DNI), etc.
  • Description of the property subject to the purchase-sale, such as: location, registration information, certificate of occupancy, mention of any encumbrances on the property.
  • Purchase price and payment method. 
  • Specification of amounts paid by the parties.
  • Price of the earnest money contract, given to the owner for signature, stating that it will be deducted from the final price.
  • Timeframe for signing the purchase agreement.
  • The type of earnest money agreement being signed, and its expiration date.
  • Signatures of the negotiators.
  • How the property will be delivered.

How much money needs to be paid with this contract?

The payment of the amount specified in the earnest money agreement is always the buyer's responsibility, considered a "token" of their intent to negotiate. The percentage to be paid can range from 5% to 15% of the agreed price, but 10% is the most common. 

It must be clear that as soon as the purchase agreement is formalized, the amount paid as earnest money must be deducted at the end of the negotiation.

How and where is the earnest money paid?

As this is a private agreement, the parties can agree on the method and location for making or receiving the earnest money payment. Here are the different methods:

  • Earnest money payment in cash
  • Earnest money payment by bank transfer
  • Earnest money payment by check

Who keeps this money?

In the case of penal earnest money, the capital disbursed serves as a guarantee for compliance with the agreement. If the buyer breaches it, they lose that capital. And if the seller withdraws, they must refund double the earnest money or more, as agreed.

How long can an earnest money contract last?

In each earnest money agreement, the term that the negotiators or parties deem appropriate is agreed upon, but you should remember that the law establishes a maximum period. This period for transferring the property, after signing the earnest money agreement, is six months.

Can this agreement be extended?

We must emphasize that this is a private agreement, and nothing obliges the parties to sign an extension of that contract. If an extension is made, an addendum must be included. This addendum must specify the new term agreed upon by the negotiators for the final signing.

When are earnest money agreements not valid?

There are several scenarios that could render an earnest money contract invalid, let's look at some of them:

  • When there are multiple owners, and only one of them signs
  • When the amount of the earnest money is not established
  • When the period for the final signing is not defined
  • When the regulations of the Civil Code are not observed

Can a breach of an earnest money agreement be claimed?

The answer is yes. For example, if the buyer refuses to comply with what was agreed upon, the seller can resort to legal action. The seller can also request the signing of the negotiation and demand payment of the earnest money as fair compensation for the damages caused.

What happens to the agreement if I don't get the mortgage?

If the earnest money agreement was signed and financing is not secured, that money will be lost, as the agreement will be breached. However, the purchase agreement could contain a provision stating that, in the event of a default, the parties are exempt from paying earnest money.

What should be considered before signing an earnest money agreement?

There are many elements to review, so it's important to seek professional advice, but in its absence, you should confirm that:

The agreement complies with the regulations of the Civil Code

The involved parties are those who should be present

There is no overreach in the wording, such as adding illegal clauses
