When buying property in Portugal, you will come across a specific agreement called the Contrato de Promessa de Compra e Venda (CPCV). The CPCV Portugal is a promissory contract that is significant in the property buying process as it provides substantial protection to buyers and sellers.

In Portugal, the CPCV acts as a preliminary agreement that precedes the final deed of sale, outlining the terms of a real estate sale. The promissory contract is legally binding and confirms the buyer’s intention to proceed with the purchase. It makes it difficult for either party to back out of the sale agreement, ensuring its completion and offering security to the buyer.

Although some sellers may suggest skipping this contract to reduce legal costs, doing so diminishes the buyer’s level of protection.

In this article, we’ll explain the role and importance of the promissory contract. We will also explore:

  • What is a promissory note?
  • Promissory contract and promissory note terms and how they differ
  • Why the promissory contract (CPCV) is always a good idea
  • Property deposits related to this written promise
  • The benefits of a secured promissory note versus an unsecured one

Understanding Types and Uses of Promissory Notes and Promissory Contracts

So, what is a promissory contract? Is it the same as a promissory note? These agreements can get confusing.

Below, we take a closer look at the differences between the two.

What is a promissory note?

promissory contract signingThe promissory note legal definition is a written, legally binding promise to repay a loan or debt under specific terms and conditions. It acts as a contract between a borrower and a lender.

A promissory note typically includes the principal loan amount, interest rate, repayment schedule (including the due date and any installment amounts), and details about late fees or penalties.

Although potentially issued by financial institutions, other organizations or individuals can use promissory notes to confirm the agreed terms of a loan. It is sort of like an IOU with more legal weight. It’s usually simple and focused on repayment of a debt, like a loan agreement.

What is a promissory contract?

On the other hand, a promissory contract, known as Contrato de Promessa de Compra e Venda (CPCV) in Portugal, is a preliminary agreement between a buyer and seller outlining the terms for a future property sale. It’s a legally binding document that secures both parties’ commitment to the transaction.

This contract is a crucial step in the Portuguese property buying process, acting as a safeguard until the final deed (Escritura) is signed.

The Promissory Contract (CPCV) in Portugal

buying a property in portugalThe promissory contract is a key step if you are considering buying a property in Portugal. It is not mandatory (although very common), and you can proceed directly to the final deed signing (Escritura) without it. 

Nonetheless, opting for the promissory contract offers substantial protection to the buyer, ensuring the completion of the sale.

Some sellers may propose bypassing this step to minimize legal expenses for both parties, but doing so significantly reduces the level of protection you have as the buyer. 

It is also possible to find a Portugal real estate lawyer, who charges reasonable attorney’s fees. The lawyer can assist you with drawing up the written agreement, understanding the subject matter hereof, and securing the promissory note in your favor. 

Before this stage, it is relatively easy for the seller to withdraw from the agreement, and this does happen in Portugal.

There are various reasons why sellers may choose to pull out, including:

  • The seller aims to relist the real estate to secure a higher price. 
  • In cases where the seller is a group of individuals, often siblings, not all of them may be willing to sell, and some may not even be aware that the property is on the market.

Signing the promissory note or CPCV significantly increases the likelihood of the sale proceeding. It defines the deal, specifying the property, purchase price, and payment date. While the deal may still fall through, at least you will have the advantage of having a written promise and reduced risk, with the CPCV protecting both parties. 

Why the Promissory Contract is a Critical Part of the Buying Process

Another crucial aspect of the promissory contract is that it formalizes all the agreed-upon terms and ensures both parties sign the document.

You may notice specific issues or missing paperwork that warrant further investigation during the house viewing. When you raise these concerns, the seller’s agent may attempt to downplay the issues, hoping you’ll proceed with the purchase without addressing them.

The CPCV prevents such practices by allowing you to include conditions such as the survey or property inspection not revealing any significant problems.

What’s more, the CPCV typically specifies what items will remain in the property upon completion of the sale. While it is not unheard of for sellers to take everything, including lightbulbs, it is also common for them to leave everything behind. This is especially the case when they are selling a property previously owned by a deceased relative and have no interest in retaining dated furniture.

Issuance timing: When do you get a promissory note or contract?

The promissory contract is the preliminary agreement that comes before signing a future property purchase agreement (final deed of sale). The purchase agreement, known as the Escritura in Portugal, finalizes the transaction, transferring ownership of the property from the seller to the buyer.

In the context of a mortgage loan agreement, a mortgage promissory note is put in place to ensure that the specified sum of money loaned, along with the interest, will be paid by the lender according to the agreed-upon terms. Your lender will typically provide you with a copy of the promissory note, along with several other documents, when you close on your home purchase.

Non-payment consequences: What happens if a promissory note is not paid?

The terms outlined in the promissory contract typically specify that if the buyer withdraws from the agreement, they forfeit the deposit. On the other hand, if the seller decides to back out, they usually have to compensate the buyer twice the deposit amount.

For mortgage loans, if the borrower defaults and does not repay the amount owed, the legal recourse could include repossessing any collateral the borrower put up against the promissory note, sending the debt to a collection agency, selling the promissory note (so someone else can try to collect it), or filing a lawsuit against the borrower.

Every CPCV should contain specific details. Below, we’ve made a list of items that should be included in this contract:

Promissory notes and contracts: The basic details

  • Identification of parties: Identification of the buyer, seller, and their representatives, including names and contact information
  • Property details: A comprehensive description of the property, including its habitation license and registration number
  • Amount owed: The CPCV should clearly state the principal amount of the selling price for the property.
  • Details of the deposit and date of payments: Specification of the deposit amount, payment method, and clarification regarding any additional payments to be made between the promissory contract and the signing of the deeds (Escritura)
  • Inclusion of any additional items or furnishings that are part of the sale
  • Definition of the sale completion date: Including the details of the witness when the deeds will be officially signed
  • Recourse for delays: A provision outlining the course of action (for example, interest to be charged) in case of any delays in the payment schedule. Such provision should also include issues with real estate governing law, or property-related delays.
  • Conditions to be met: The CPCV should outline the conditions that each party must meet before the signing of the Escritura.
  • The place where the contract is entered into and is to be enforced
  • Signature line: For all parties to sign

These elements ensure that the promissory contract includes crucial information and establishes the framework for the subsequent stages of the property transaction.

The Difference Between a Secured Promissory Note and an Unsecured Promissory Note

Just like with loans, you can get a secured promissory note or an unsecured promissory note. A secured promissory note is backed by collateral, like an asset or something of value, that can be claimed if the borrower fails to pay.

Unsecured promissory notes, on the other hand, are not tied to any collateral, which makes them riskier for the lender.

In real estate deals, this matters. A secured promissory contract helps protect both parties and ensures the buyer’s deposit isn’t lost if something goes wrong. Unsecured agreements, especially verbal ones, leave buyers more exposed — especially if you’ve already handed over your deposit.

If the buyer or seller decides to pull out of a deal, promissory estoppel is always available. It prevents either party from backing out of a written promissory agreement or a promise when the other party has relied on it to their detriment.

Deposits According to Promissory Notes

One crucial stage in the property acquisition process involves placing a deposit and signing the promissory contract. After making an initial offer, the promissory contract confirms your intention to proceed with the purchase.

While submitting a deposit is a customary practice in numerous countries, it holds greater significance in Portugal due to the promissory contract (CPCV), which imposes significant obstacles for either the buyer or seller to withdraw from the agreement.

When entering into the promissory contract, it is customary for the buyer to provide a deposit, known as the Sinal, typically amounting to between 10 percent and 25 percent of the property’s value. Still, if both buyer and seller agree, this can be lower.

Payment according to the promissory agreement

Typically, the deposit is paid via a cheque or bank transfer, usually made payable to the seller directly or to the seller’s lawyer. It is worth noting that utilizing an escrow account to hold the deposit funds is not commonly observed in Portugal (an escrow account is a third-party account where funds are held before they are transferred from one party to another).

Key Takeaways About the Promissory Contract (CPCV)

Now that we understand the definition of promissory note or promissory contract, we can appreciate its importance. Although it may seem a time-consuming and stressful addition to the process of buying property in Portugal, the CPCV is an assurance and protection for the buyer.

Don’t bypass this; don’t let any seller or seller’s agent talk you out of signing a CPCV. In addition, make sure to use the help of a buyer’s agent, such as Goldcrest, to ensure that your best interests are always represented.

Frequently Asked Questions about the CPCV in Portugal

A promissory note, sometimes called a promissory contract, is a written promise to pay someone back a specific amount of money. When you sign one, you’re promising to repay a debt on a specific date or whenever the lender asks for it. It lays out all the details of the loan, including how and when you’ll pay the money back.

Yes, a promissory agreement is a legally binding contract. It is a legally binding agreement between two parties that establishes the terms and conditions for a specific transaction, often related to the sale or purchase of a property.

In Portugal, CPCV stands for Contrato de Promessa de Compra e Venda, which translates to “Promissory Contract of Sale.” It is a legal document that solidifies the buyer’s and seller’s intentions and obligations in a property transaction. You can get a real estate lawyer in Lisbon to draft the contract for you.

A promissory contract is an agreement between a buyer and seller confirming the intention to proceed with a property sale. One example of another type of contract that differs from this would be the Escritura, the final deed of sale, where both parties sign the deed once full payment is made and the property is officially sold.

Other contracts will serve completely different purposes. For example, a mortgage agreement is a contract specifically for financing a property purchase.

The promissory contract, also referred to as the promissory purchase and sale agreement, must include the following details:

  • The identification of the buyer, seller, and their representatives 
  • A property description, habitation license, and registration number
  • The principal amount of the selling price for the property
  • The deposit amount, payment method, and clarification regarding any additional payments between the promissory contract and the signing of the deeds, including attorney fees, interest rates, exchange commission, and property taxes. 
  • All the conditions that each party must meet before signing the final deed.
  • Deadline for completing the public deed

It is not a strict requirement, and real estate agents representing the sellers may try to avoid drawing up a promissory note to avoid additional legal fees. However, having a written promissory note stating the intention to sell is highly advised in case the deal falls through.

Once the CPCV or promissory contract is signed, it can be modified, but it requires the agreement of all parties involved.

The buyer or seller of the property can cancel the CPCV, but not without some liability. If either party seeks to cancel the agreement, the party canceling will be liable to pay double the 10 percent deposit paid with the CPCV.

Yes, a promissory contract is a legally binding agreement in Portugal. Both parties are obligated to fulfill the terms agreed upon, and failure to do so can result in legal consequences.

If there is proof of a signed written agreement, promissory contracts are enforceable in court. If the buyer or seller decides to pull out of a deal, promissory estoppel is always available. In these cases, the courts will determine if it’s fair to hold someone to their word based on how much the promise affected the other person’s deposit, agreements for final payment, and financial position.

When a promissory contract for the purchase and sale of a property is signed, it can be registered at the Conservatory for Real Estate Registry (Conservatória do Registo Predial) to protect the promissory buyer’s future ownership rights against third parties.

As a result, if the seller tries to sell the property to someone other than the promissory buyer, the promissory buyer can enforce their rights through the courts, compelling the seller to honor the original agreement and transfer ownership of the property to them.

A promissory contract can be terminated in Portugal by mutual agreement, fulfillment of its terms, or through legal action if there’s a breach. Specific conditions for termination should be outlined in the contract. This is referred to as the direito de retratação, the right to withdraw, and this can be stimulated in the promissory contract, allowing parties to back out under specific, mutually agreed conditions.

In the event of a breach of contract, known as an incumprimento in Portugal, the non-defaulting party has several options: They can seek to enforce the contract, activate a specific penalty clause, or terminate the contract and receive compensation based on the original deposit. Typically, the promissory seller keeps the original deposit, but the promissory buyer may be entitled to claim twice that amount.

Mutually agreed penalty clauses can also be included in the contract, known as cláusulas penais.

Much like the CPVC, a promissory note issued by a financial institution for a mortgage loan also protects both the buyer and seller in a property sale, such as if the borrower defaults or fails to honor the agreement of the loan amount.

The promissory contract is usually signed in front of a Notary (Notário). This helps to ensure legal compliance, verifies the parties’ identities, and certifies the document’s authenticity.

When foreigners purchase property, they need to be aware of the various property taxes involved, both at the time of purchase and on an annual basis. During the purchasing process, these taxes include the Property Purchase Tax/Property Transfer Tax (IMT) and Stamp Duty.

On an annual basis, owners are required to pay the Municipal Property Tax (IMI). Additionally, if you plan to sell your property, you should consider the Capital Gains Tax. For more information, refer to our article: Property Taxes in Portugal 2025: An Overview.

Let’s first answer the question: What is a promissory note? A promissory note is a written promise by one party to make a payment of money at a date in the future.

So, is a promissory note a contract?
A contract is broader — it lays out all the terms of an agreement between two or more parties, like buying a home, timelines, obligations, penalties, and more.

In Portugal, the promissory contract (Contrato de Promessa de Compra e Venda) is a formal pre-sale agreement with detailed conditions, not just a written promise to pay.

An IOU is a basic statement that just says that someone owes money, without many details. A promissory note goes further: It includes the amount owed, the repayment date, interest (if any), and both parties’ signatures. It’s much more formal and enforceable than an IOU.

As long as a promissory note includes all the essential elements (details of both parties, the loan amount, repayment terms, signatures), it’s a fully legally binding agreement. While not essential, you can have the promissory note notarized to add extra legal protection.

While promissory notes are useful, offering clear loan terms and legal enforceability, they’re not bulletproof.

If the terms are vague or not properly written, it can lead to misunderstandings, defaults, or legal headaches. Plus, enforcing them through the courts can take time if things go south.

The terms outlined in the promissory contract typically specify that if the buyer withdraws from the agreement, they forfeit the deposit. If the seller decides to back out, they usually have to compensate the buyer twice the deposit amount.

For mortgage loan promissory notes, if the borrower defaults and does not repay the amount owed, the legal recourse could include repossessing any collateral the borrower put up against the promissory note, sending the debt to a collection agency, selling the promissory note (so someone else can try to collect it), or filing a lawsuit against the borrower.

A promissory note typically contains the names and addresses of the parties involved, the amount to be repaid, the interest rate (if applicable), the payment schedule or due dates, and details about default and late payments.

Two examples are:

  • A written promise to repay personal loans between family members
  • A car loan promissory note

A promissory note serves as a formal commitment by one party to pay a specified amount of money to another, either when requested or at a predetermined future date.

By offering flexibility, promissory notes provide diverse opportunities in business, from banking and financing (student loans, mortgages, car loans) to loans and financing agreements between businesses.
