When buying property in Portugal, one of the most important legal steps is signing the Promissory Contract (Contrato-Promessa de Compra e Venda — CPCV).
This agreement protects both the buyer and the seller by establishing the terms of the property transaction before the final deed is signed. The promissory contract in Portugal secures the purchase price, sets deadlines, and defines the obligations of both parties.
Understanding how the CPCV in Portugal works is essential for anyone involved in a real estate transaction. In this guide, we explain how the promissory contract functions, what it includes, and why it plays a crucial role in the Portuguese property buying process.
If you want to understand the full buying process, see our guide to buying property in Portugal.
What Is the Promissory Contract in Portugal (CPCV)?
The Promissory Contract of Purchase and Sale, known in Portuguese as Contrato-Promessa de Compra e Venda (CPCV), is a legally binding agreement signed between the buyer and the seller before the final property deed.
This contract establishes the conditions under which the property sale will be completed. It acts as a preliminary agreement that secures the transaction until the official transfer of ownership takes place through the Deed of Purchase (Escritura Pública).

Why the Promissory Contract Is Important
The CPCV in Portugal plays a key role in protecting both parties involved in the property transaction.
The contract:
- secures the agreed purchase price
- defines deadlines for completing the sale
- establishes penalties if either party withdraws
- outlines the responsibilities of the buyer and seller
- provides legal certainty until the final deed is signed
For international buyers especially, the promissory contract helps reduce uncertainty and ensures that the property remains reserved while legal checks and financing are completed.
Key Elements of a Promissory Contract in Portugal
A promissory contract (CPCV) typically includes several essential elements that define the conditions of the transaction.
| Element | Description |
|---|---|
| Deposit (Sinal) | A financial commitment paid by the buyer, usually around 10% of the purchase price |
| Conditions | Requirements that must be fulfilled before the final deed (financing, inspections, etc.) |
| Completion Date | Deadline for signing the final deed of purchase |
| Penalties | Consequences if either party fails to fulfil the agreement |
| Payment Terms | Details of how and when payments will be made |
These clauses ensure that both parties understand their obligations and that the transaction proceeds smoothly.
Property Deposit in Portugal (Sinal)
One of the most important components of the promissory contract in Portugal is the property deposit, known as the sinal.
The deposit represents the buyer’s commitment to purchasing the property and is typically around 10% of the agreed purchase price, although the exact amount can vary depending on the negotiation between buyer and seller.
The deposit provides financial protection for both parties.
If the Buyer Withdraws
If the buyer decides not to proceed with the purchase after signing the promissory contract, the seller usually has the right to keep the deposit.
If the Seller Withdraws
If the seller cancels the transaction without valid justification, Portuguese law generally requires the seller to return double the deposit amount to the buyer.
This rule ensures fairness and discourages either party from breaking the agreement.

Conditions and Obligations in the CPCV
The promissory contract also defines the conditions that must be fulfilled before completing the final property transaction.
These conditions often include:
- mortgage approval from a bank
- completion of legal due diligence
- property inspection or structural checks
- confirmation that the property has no debts or legal issues
For example, many buyers choose to conduct a property inspection in Portugal before proceeding with the final purchase.
Completion Date and Final Deed
The promissory contract must specify a deadline for completing the transaction.
This deadline indicates when the parties must sign the final Deed of Purchase and Sale (Escritura Pública).
The deed is usually executed at:
- a notary office, or
- through a qualified real estate lawyer
After the deed is signed, the property ownership is officially transferred to the buyer and registered with the Portuguese Land Registry.
Payment Methods in Portugal Property Transactions
In Portugal, property deposits and payments are typically made through secure banking methods.
Common payment methods include:
- bank transfers
- certified bank cheques
Unlike some countries, escrow accounts are not commonly used in Portugal. Instead, transactions rely on the legal framework provided by notaries and lawyers.
Is the Promissory Contract Mandatory in Portugal?
The promissory contract (CPCV) is not legally required in Portugal, but it is widely used and strongly recommended.
Although it is possible to move directly to the final deed without signing a CPCV, doing so increases the risks for both buyer and seller.
In most property transactions, the CPCV acts as an important legal safeguard that secures the agreement before the ownership transfer.
Who Should Prepare the CPCV in Portugal?
The CPCV should always be prepared or reviewed by a qualified legal professional.
The safest option is to work with a real estate lawyer in Portugal, who can:
- verify the property records
- confirm ownership details
- ensure the contract complies with Portuguese law
- include clauses that protect the buyer or seller
